Description

The present invention relates to a copyright protection system, in particular the more stringent protection of the copyright, and about the copyright protection system that analysis is difficult even performed by a third party.

Conventionally, trial software downloaded from the Internet or shareware software such as software with limited functions has a trial period. After the trial period is over, use is restricted, registration is completed, and passwords etc. are entered Until it is done, the function is limited. If the user wishes to continue using the function or wants to use the function normally, he / she applies to the author for registration. Thereafter, the restriction or the like is lifted by inputting the password transmitted from the author or the like into the computer.
By the way, such shareware software and the like can be installed and used on a plurality of personal computers with this password. Therefore, it was easy to be transferred to others.

  In addition, the above-described problems also occur in software and music provided on a CD-ROM or the like. In particular, software, music, image data, etc. supplied or distributed as digital information are problematic because the quality does not deteriorate even if copied.

  In addition, the Internet connection and permission to enter the homepage are currently managed with a password, etc., and if you know this password etc., even someone other than the applicant for registration can freely use the copyrighted work such as the homepage. There is also a problem.

  Furthermore, users do not always access these copyrighted works from a single information processing device, and due to recent technological advances in information processing devices, information processing devices must be replaced early. Is likely to be. For this reason, it is necessary to give freedom to use while protecting the copyright (Patent Document 1).

Furthermore, if the copyright manager can easily grasp and process the state in which the copyrighted work is illegally used, it is possible to quickly deal with the illegality.
Furthermore, it is desirable that the copyrighted work can be used by a family other than the person who purchased the copyrighted work on a per information processing device basis.
In this case, it is desirable to protect the privacy of the person who purchased the copyrighted work.

Furthermore, while ensuring the use of such a copyrighted work, it is desirable that if it is the person who purchased the copyrighted work, the copyrighted work can be accessed by any information processing device owned by the person (patent Reference 2)
Furthermore, it is necessary to make copyright protection more strict and to make analysis by a third party more difficult.
Japanese Patent Laid-Open No. 2002-24450 Japanese Patent Application No. 2002-324344

The present invention has been made in view of such conventional problems, aims to provide a the more stringent protection of the copyright, and analyzed by a third party is unlikely to further performed copyright protection system And

For this reason, the present invention (Claim 1) is a copyrighted work in which the first authentication key is incorporated in advance, and a copyright capable of managing the right to use the copyrighted work in a state of being separated and independent from the copyrighted work. A copyright protection system provided with protection software, which includes registration information of at least one copyrighted work, unique information based on an information processing apparatus in which the copyrighted work is used, or a bio of an operator who operates the information processing apparatus A management file (file F1) for managing unique information based on metrics information, an encryption key generating means for generating an encryption key generated by a predetermined algorithm based on the unique information stored in the management file, and part or all files constituting the work that has been encrypted based on the encryption key, corresponding to the registration information and a second authentication key stored in the management file, The second authentication key acquired from the management file and the acquired previously incorporated the first authentication key has to work, and the first authentication key and the second authentication key of which is the acquired Authentication key determination means for determining whether or not they match, at least one of hardware, software, ID of a recording medium with an ID, and biometric information of an operator who operates the information processing apparatus Unique information detecting means for detecting the unique information, unique information comparing means for comparing the unique information detected by the unique information detecting means with the unique information stored in the management file, and an authentication result by the authentication key determining means And when the comparison result of the unique information comparison means matches, a decryption key is obtained by a predetermined algorithm based on the unique information stored in the management file. And a decryption key generating unit configured to decrypt the file based on the decryption key. The copyright protection software includes at least the management file, the authentication key determination unit, and the unique information detection. And a unique information comparison unit, a decryption key generation unit, and a decryption unit.

  The copyrighted work includes, for example, software such as business software and game software, files such as music, images, and moving images, homepages on the Internet, broadcast data broadcast from broadcast stations, videos, and the like. The copyrighted work may be stored in an information processing device such as a personal computer, mobile information terminal, game machine, TV, mobile phone, etc., but is stored as a content on a website on the Internet in the form of a homepage There is also. The management file is stored in the information processing apparatus of the user and manages registration information of at least one copyrighted work. Registration information is information managed by the copyright manager. It is desirable that the predetermined algorithm is predetermined or selectable so as to be different for each work. The predetermined algorithm may be specified by a key generation logical value indicating a logical procedure for generating the unique information key. The logic procedure may be partially variable, and command data for this variable may be set in the key generation logic value. By making the algorithm different for each work, it can be made difficult to analyze.

  Since the unique information is stored in the management file, the same data can always be referred to regardless of a partial change of the components in the information processing apparatus. For this reason, even if the specific information differs due to partial modification or the like, conversion such as decoding can be performed based on the stored specific information. A part of the file is a program instruction, data, or the like, and it is desirable that the location where the program instruction exists, the location where the data, etc. are referred to correspond to a part where the function is restricted. If it is part of the file, the startup speed is also fast. It is difficult to analyze the minute program by conversion such as encryption. It is possible to make the conversion key such as encryption and decryption unique and to make analysis difficult by a combination of unique information and random numbers that differ for each information processing device and a predetermined algorithm that differs for each copyrighted work. The conversion key does not need to be saved, and the file can be converted simultaneously with generation. Therefore, since the conversion key is not exposed to the outside and is not left in the information processing apparatus or the like, there is no worry of being analyzed. The conversion key is a key necessary for converting a file or data into data in a format that is difficult for a third party to analyze, such as encryption, decryption, compression, decompression, or the like. The conversion means may exist in the information processing apparatus on the user side, or may exist in the server on the copyright manager side.

The present onset Ming, stored in the management file, authentication key and authentication key such as a password that is corresponding to the work, the authentication key to determine whether to match the authentication key possessed by the work Judgment means, unique information detection means for detecting at least one of unique information such as hardware and software constituting the information processing apparatus, ID of recording medium with ID and biometric information, and detection by the unique information detection means Unique information comparison means for comparing the unique information stored with the unique information stored in the management file, and the unique information stored in the management file when the authentication is confirmed by the unique information comparison means and the authentication key determination means. configured to include a conversion key generated by the predetermined algorithm based on the information, and a conversion means for data converting the file based on the conversion key It may be.

After the file is converted into data, this file is used as a program command or data, or reproduced. At this time, it may be determined again whether or not it matches the authentication key. At this time, multiple protection by different methods of copyrighted works is possible. When the copyrighted work and the copyright protection software are independent, it is desirable from the viewpoint of safety that the authentication key match determination is performed on the copyrighted work side or on the copyright protection software side.
The unique information comparison means compares unique information. Therefore, the following data conversion is not performed in different information processing apparatuses. For the unique information, a predetermined weight, priority order, or the like may be considered. The conversion such as encryption is performed based on information unique to the personal computer, and the other information processing apparatus does not perform conversion such as decryption. The authentication key is not exposed to the outside and is secure. Since the authentication key is given based on the unique information and the determination of the personal authentication, strict management is possible.

Furthermore, the onset Ming, a management file that manages registration information of at least one work, is stored in the management file, and authentication key such as a password that is corresponding to the work, the authentication key is the work Authentication key determination means for determining whether or not the authentication key has, and at least one unique information such as hardware, software, ID of recording medium with ID and biometrics information constituting the information processing apparatus Unique information detecting means for detecting, unique information comparing means for comparing the unique information detected by the unique information detecting means with the unique information stored in the management file, and a part or all of the files constituting the copyrighted work when the unique information comparing means and the when it is confirmed in the authentication by the authentication key determination unit is configured to include a conversion means for data converting the file It may be.

Data conversion is performed on the file based on the determination result of the matching between the authentication key stored in the management file and the authentication key of the copyrighted work and the comparison determination result between the detected unique information and the unique information stored in the management file.
As a result, the file can be data-converted based on whether or not it is a registered authenticated person and whether or not it is a registered information processing apparatus. Therefore, unauthorized use of the copyrighted work can be prevented in advance.

Furthermore, the onset Ming, a management file that manages registration information of at least one work, is stored in the management file, and authentication key such as a password that is corresponding to the work, the authentication key is the work Authentication key determination means for determining whether or not the authentication key has, and at least one specific information such as hardware, software, ID of ID-added recording medium and biometric information constituting the information processing apparatus A unique information detecting means for detecting, a unique information comparing means for comparing the unique information detected by the unique information detecting means with the unique information stored in the management file, the unique information comparing means and the authentication key judging means; When the authentication is confirmed, a conversion key generated by a predetermined algorithm, a part or all of the files constituting the copyrighted work, and the file The may be configured with a conversion means for data conversion based on the conversion key.

  Judgment is made between the authentication key stored in the management file and the authentication key of the copyrighted work, the detected unique information is compared with the unique information stored in the management file, and conversion is performed using a predetermined algorithm based on the result. Generate a key. Based on this conversion key, the file is converted into data by encryption processing, compression processing, or the like.

Furthermore, the onset Ming, a management file that manages registration information of at least one work, is stored in the management file, hardware, software, ID and biometric information of the ID with the recording medium constituting the information processing apparatus At least one of the unique information, a conversion key generated by a predetermined algorithm based on the unique information, a part or all of the files constituting the copyrighted work, and the file based on the conversion key may be configured with a conversion means for data conversion.

  Since the unique information is stored in the management file, the same data can always be referred to regardless of a partial change of the components in the information processing apparatus. For this reason, even if the specific information differs due to partial modification or the like, conversion such as decoding can be performed based on the stored specific information.

Further product, the onset Ming, hardware constituting the information processing apparatus, software, and at least any one of the specific information such as the ID and the biometric information of the ID with the recording medium by a predetermined algorithm based on the peculiar information Conversion key, a part or all of the files constituting the copyrighted work, conversion means for converting the data of the file based on the conversion key, and setting means for setting the logical procedure of the algorithm May be .

  Since the algorithm logical procedure can be set, the algorithm can be made different for each copyrighted work when generating the conversion key. For this reason, analysis by a third party is difficult.

Furthermore, the onset Ming, stored in the information processing apparatus, the registered unique information is information that has been registered, the hardware constituting the information processing apparatus, software, ID of ID with the recording medium and biometric information, etc. Specific information detecting means for detecting at least one of the unique information, and unique information comparing means for comparing the unique information detected by the unique information detecting means with the registered unique information, the unique information comparing means when more than a predetermined ratio did not match in contrast with, or characterized by predetermined program processing is not performed.

  The comparison of the unique information may be determined based on a perfect match, or may be determined based on whether or not it is equal to or greater than a predetermined ratio. In this case, it is possible to absorb a partial mismatch of the unique information with respect to a partial change or the like of a part in the information processing apparatus within a predetermined margin. Therefore, the file can be converted even if the information processing apparatus is partially modified, and the user is relieved. For the unique information, a predetermined weight, priority order, or the like may be considered.

Furthermore, the onset Ming, management and advance part or work everything is data converted based on a predetermined conversion key, stored in the information processing apparatus of the user, a restoration key for restoring data該著crops A unique information detecting means for detecting at least one unique information such as a management file, hardware constituting the information processing apparatus, software, ID of a recording medium with ID, biometric information, and the like, and the unique information detecting means The storage means for storing the detected unique information, the comparison means for comparing the unique information stored in the storage means with the unique information detected by the unique information detection means, and the comparison result in the comparison means it may be configured and a data restoration means for performing data recovery of the work by the restoration key based.

  Some or all of the copyrighted work has been previously converted based on a predetermined conversion key. For example, it is provided in the form of a site on the Internet or a CD. The restoration key is stored and managed in a management file of the user information processing apparatus. It is desirable that at least one copyrighted work information is managed in the management file. When the identification is confirmed by the confirmation of the unique information, the copyrighted work is restored with this restoration key.

Furthermore, the onset Ming, a key generating unit for generating the predetermined conversion key and the restoration key is stored respectively in said management file and copyright management center, the same or corresponding across copyright management center and the management file and attached to the management number for managing the work of the individual, may be characterized by the restoration key generated by said key generation means is stored under the control number.
The key generation means generates a predetermined conversion key and restoration key. A work number is assigned to each work when the work is provided in the form of a download or a CD. This management number is the same or associated between the copyright management center and the management file. The generated restoration key is stored under the management number.
As described above, a different restoration key can be prepared for each copyrighted work to be downloaded. For this reason, security is improved.

Furthermore, the onset Ming, in advance part or all of the work that has been data converted based on a predetermined conversion key, a registration unit for registering request for permission to use該著crops, by the registration application, When the use of the copyrighted work is permitted, a sending means for sending a restoration key for restoring data of the copyrighted work to the user, and a restoration stored in the information processing apparatus of the user and sent by the sending means A management file for managing keys, data restoring means for restoring data of the copyrighted work based on a restoration key stored in the management file, and reproduction for reproducing or using the copyrighted work data restored by the data restoring means it may be configured and a like means.

  When the use of the copyrighted work is permitted by the registration application, a restoration key for restoring the data of the copyrighted work is sent to the user. At this time, a copyrighted work may also be sent. It is desirable that at least one copyrighted work information is managed in the management file.

Furthermore, the onset Ming, hardware constituting the information processing apparatus, software, and unique information detecting means for detecting at least any one of the specific information such as the ID and the biometric information of the ID with the recording medium, said intrinsic information detection and a storage means specific information detected by the unit is stored, the restoration keys may be characterized in that it is produced key based on the unique information stored in said storage means.

  Since the restoration key is generated based on the unique information stored by the storage unit, stable key generation can always be performed even when there is a change in the parts of the information processing apparatus.

Furthermore, the onset Ming, the restoration key is a key generated by a predetermined algorithm based on the unique information stored in said storage means, said predetermined algorithm is stored respectively in said management file and copyright management center the in sending unit, the sent predetermined algorithm instead of the recovery key, in the management file may be characterized in that the predetermined algorithm instead of the restoration key is managed.

  The restoration key is generated by a predetermined algorithm based on the unique information saved by the saving means. Since the restoration key itself is not stored in the management file, analysis by a third party becomes difficult.

Furthermore, the onset Ming is a recording medium, copyright protection system programs may be recorded.

  As described above, according to the present invention, a part or all of the files constituting the copyrighted work are converted based on the unique information stored in the management file. Regardless of the change of the parts and the like, conversion such as decoding can be surely performed based on the stored unique information. Further, since the conversion key is generated based on a predetermined algorithm, the program is hardly analyzed. If the conversion key is different for each work, the analysis becomes more difficult.

Since the conversion key is not exposed to the outside and does not remain in the information processing apparatus or the like, there is no worry of being analyzed.
After the file is subjected to conversion such as decryption, the file is used as a program command, data, or the like, reproduced, or the like. At this time, it may be determined again whether or not the authentication keys match. At this time, multiple protection by different methods of the copyrighted work (authentication key matching method and file conversion method such as encryption) is possible.

Since the configuration is such that the comparison of the unique information is determined based on whether or not it is greater than or equal to a predetermined ratio, it is possible to absorb a partial mismatch of the unique information caused by a change in the components in the information processing apparatus within a predetermined margin. For this reason, even if the information processing apparatus is partially modified, the file can be converted such as decryption, and the user is relieved. The conversion is performed based on information unique to a personal computer, and other information processing apparatuses do not perform conversion such as decryption.
The authentication key is not exposed to the outside and is secure. Since the authentication key is given based on the unique information and the determination of the personal authentication, strict management is possible.

  Hereinafter, embodiments of the present invention will be described. A schematic overall configuration diagram of the first embodiment of the present invention is shown in FIG. In FIG. 1, software 1 with function restriction (including trial version software) is downloaded on the Internet or obtained on a compact disc (including CD (MD, DVD, etc.)) or a flexible disc (FD). is there. The function-limited software 1 is, for example, application software, shareware software, game software, video software, music software, or the like.

  When installing the software 1 with function restriction on the personal computer 10, the execution file 7 is, for example, a case where a Windows (R) 95 of Microsoft (R) is used as a predetermined location of the basic drive (for example, an operating system (hereinafter referred to as OS)) In this case, the file F1 is created in the Windows (R) directory or the like.

  As shown in FIG. 2, the file F1 includes information unique to the personal computer obtained from the hardware information of the personal computer 10, OS information such as a user name and product ID number, a drive on which the function-restricted software 1 is installed, A directory (hereinafter referred to as directory information), installation information such as installation date / time, minute / second, information on whether or not the OS of the personal computer has been returned to the beginning, and uninstallation information of the software 1 with function restriction are stored.

  In FIG. 2, a history of installation information is taken for each function-limited software 1. Therefore, when the function-limited software 1 is installed, if the file F1 already exists, the file F1 is not overwritten and updated, but its installation information history is taken. In addition, since the file F1 is not overwritten and updated as described above, the data of the original file F1 is not lost when the software 1 with function restriction is uninstalled and then installed again as described later.

  The information specific to the personal computer 10 is, for example, a personal computer model such as FMVT423B for a Fujitsu (R) personal computer or PC9821Xa16W30 for a NEC (R) personal computer, and is information that can be acquired by software from existing hardware information. . However, this type does not necessarily need to be a full type, and may be partial information such as PC9821 and FMV.

  That is, information unique to the personal computer 10 is not recorded and prepared for the present invention, but may be information that can be read from existing hardware and system information. However, it is not preferable that it can be easily changed such as a CPU type even if it is readable. In other words, information that is premised on replacement of parts is not preferable as information. Also, modem location information, e-mail personal information, e-mail address, cookie, IP address, etc. can be used. However, since these pieces of information may be the same data in other personal computers, it is desirable to use them in combination with other hardware and system information.

  The OS information includes, for example, a user name, a product ID number, an OS installation execution date and time, etc. set at the time of installing Windows (R) 95. When using this OS installation execution date and time, for example, it is possible to refer to the update date and time of each directory of the basic drive in which the OS is installed.

  The installation information of the function-restricted software 1 includes, for example, the name of the function-restricted software 1, directory information in which the function-restricted software 1 is installed, and the date, time, day, hour, minute, and second of the execution in which the installation was performed. As shown in FIG. 2, the directory information and the year / month / day / hour / minute / second of installation execution are saved every time the software 1 with function restriction is installed.

  In this way, the directory information and the date, time, minute, and second of the execution of the installation are also acquired if the information on when, where and what software is installed on this personal computer can be obtained. It is because it can identify.

  However, it is not necessary to have all of these pieces of information. For example, it is possible to specify a personal computer in which the function-restricted software 1 is sufficiently installed only by installing the function-restricted software 1. In order to make it difficult for the user to recognize the year / month / day / hour / minute / second of installation execution, the year / month / day / hour / minute / second of installation execution may be intentionally shifted by a predetermined time.

  Further, the software 1 is executed by the first activation or the like, and it is possible to replace the installation information by using the time of each node used. Further, the creation date / time / minute / second of the file created at the time of the registration application described later may be used, or these information may be appropriately combined to form data.

  Furthermore, instead of (or in combination with) this installation information, it is also possible to use the numbers and symbols randomly generated by the function-restricted software 1 as registration application information. This is because even if the numbers and symbols are randomly generated, it is sufficient to specify the personal computer to be used and the software 1 with function restriction if the registration applicant and the registered applicant have the same data.

  The reason for saving the history is that the case where the software 1 with function restriction is uninstalled and then reinstalled is considered. This is because the drive and directory may be installed differently during re-installation.

  These directory information and installation execution year / month / day / hour / minute / second are grouped for each software 1 with function restriction in FIG. 2 and shown as one file. It is also possible to do. It is desirable that these pieces of information are encrypted and stored.

  The function-restricted software 1 is a function that is restricted in use. In addition to the original application software part created by the copyright holder, the software 1 with function restriction includes a registration software part 3 for officially registering the software 1 with function restriction and an identification software 5 described later. It is.

  In order to make the registration software part 3 function, for example, this function or the like is incorporated in the HELP or the like of the function-limited software 1 so as not to interfere with the use of the original application software part. Or it is good also as a special icon display, an executable file format, etc. The user tries the software 1 with function restriction, and when he / she wants to continue formal registration, after selecting HELP, the user subsequently selects the registration application button 11 by clicking or the like.

  The following operation is executed by selecting the registration application button 11. This will be described with reference to the flowchart of FIG.

  First, when the registration application button 11 is clicked in step 1 (hereinafter abbreviated as S1), the presence of the name of the function-limited software 1 is confirmed in the file F1 in step 3. Then, for example, the latest installation information is selected from the history of the file F1 of the software 1 with function restriction, and a mark * is added to the directory information and the year / month / day / hour / minute / second of execution as shown in FIG. Thereafter, in step 5, the installation information before this installation information is deleted from the history. This is because only the latest information with a mark * is registered information.

  Next, in step 7, a backup request for the file F1 is displayed on the screen so that a storage disk such as a flexible disk or MO is inserted into the flexible disk drive or the like. At this time, in step 9, the file name is saved by changing the file name to Fa with an arbitrary name in order to hide the file location under the Windows (R) directory.

  The reason why the file F1 is backed up in this way is because the case where an OS such as Windows (R) 95 is reinstalled after the application for registration is taken into consideration. In this case, the registration application work is wasted. Therefore, if it is clear that the OS will not be reinstalled after the registration application, such backup work can be omitted.

  Next, when the registration application of the function-limited software 1 is transmitted by e-mail, an e-mail registration application icon is clicked in step 11. At this time, e-mail software previously associated or registered with the function-restricted software 1 such as Microsoft® Exchange by Microsoft® is automatically started in step 13, and e-mail is sent in step 15. Automatically created.

  In the automatic creation of the e-mail, first, a transmission destination (for example, a copyright manager) determined in advance is automatically set based on information from the registration software portion 3. In addition, the following mail text is automatically input from the information stored in the file F1. In the mail text, items necessary for registering the function-limited software 1 such as the operating system, personal computer model, user name, software name, and registration fee are selected and entered.

  In addition, when the number of software reaches more than one, or when more than one PC is used, the OS used, PC type, user name, software name, registration fee, etc. are required for each PC for which registration application is made, which will be described later Items are selected and displayed. At this time, in order to change the registration fee according to the number, the total number is confirmed, a registration fee preset according to the total number is assigned and displayed, and the total amount is described.

  If there is no mistake in this display, the user clicks a confirmation button in step 17. At step 19, the email is sent. At this time, the file F1 is also attached and transmitted. However, in order to hide the location of the file F1, the name of the file F1 is changed to Fa and attached.

  The contents of the file F1 are encrypted. If the file F1 is automatically attached when an e-mail is sent, the file F1 can be sent without being recognized by the user. The file F1 attached to the e-mail is deleted immediately after the transmission is completed in step 23.

  Thus, the user can omit troublesome registration work. Confirmation can be made promptly without mistakes in information input. In addition, since this data is stored in an e-mail, it is possible to easily refer to a target personal computer that can be used for confirmation of purchase or the function-limited software 1 later by starting the e-mail software. Since the transmission data is text data, the amount of data is small, so the burden during transmission is light.

  The application for registration of the function-limited software 1 may be made to communicate with a server computer via a site on the Internet. At this time, the registration application button 11 is clicked to automatically connect to a site on the Internet provided by the copyright manager, and the file F1 is attached to the destination by the registration software portion 3 in the form of mail attachment or automatic data transmission. Sent. The contents of the file F1 are analyzed by the server computer, and the operating OS, personal computer model, user name, software name, registration fee, etc. are selected and displayed on the home page. If there is no mistake in this display, the user clicks a confirmation button arranged on the home page. Since the data at the time of registration is stored in the server computer, it is possible to refer to the target personal computer on which the purchase confirmation and the software 1 with this function restriction can be used later on the homepage.

  Data for which registration has been applied is stored in the copyright manager, etc., and if there are any abnormalities in the software 1 with restricted functions for each PC manufacturer or model, search and identify these users. Therefore, it is possible to promptly provide the user with the information, version upgrade information or version upgrade software.

  When the user makes an inquiry about the software 1 with function restriction, when the inquiry button (not shown) is clicked, the OS used, the computer type, the user name, and the software name are determined from the information stored in the file F1. Etc. are automatically entered. The destination is also automatically entered. The user describes only the contents of the inquiry and clicks the confirmation button to send it as an e-mail. For this reason, the inquiry work can be easily performed while proving that the inquiry is from the user.

  It is also possible to make an inquiry to the function-restricted software 1 via a site on the Internet. At this time, when the inquiry button is clicked, the site is automatically connected to a site on the Internet provided by the copyright manager, and the file F1 is transmitted to the transmission destination as an email attachment. Alternatively, the file F1 is automatically transmitted to the transmission destination. The contents of the file F1 are analyzed by the server computer, and the operating OS, personal computer model, user name, software name, etc. are determined. These pieces of information are preferably displayed on the user side. The user can make an inquiry by filling out an inquiry item in an inquiry column provided on the homepage and sending it.

  On the other hand, the user who cannot use the Internet mail clicks the mail registration application icon in step 25. At this time, the text editor is automatically activated in step 27, and a display in which items necessary for the registration application are entered in step 29 is displayed. The text sentence has the same description as the mail sentence. The text editor is not limited as long as the text can be displayed. If there is no mistake in this display, the user presses the confirmation button in step 31.

  Thereafter, in step 33, a request screen for inserting a flexible disk or the like into the flexible disk drive or the like is displayed. In step 35, the file F1 is saved on the flexible disk or the like with the name changed to Fa, and the text sentence of the registration application is also saved. The contents of the file F1 are encrypted. In step 37, registration can be made by mailing this flexible disk to the copyright manager.

  After that, the user remits the software purchase fee on the net or by mail or bank transfer. At the transmission destination, after confirming the payment, necessary information FB is extracted from the information of the transmitted file F1.

  The necessary information FB includes, for example, as shown in FIG. 4, a personal computer model, a user name, a product ID number, a software name, directory information where the software with function restriction 1 is installed, and a date of execution when the installation is performed. Date / time / minute / second (directory information and year / month / day / hour / minute / second of execution are those of the mark *), which is sufficient information for identifying the personal computer on which the software 1 with function restriction is installed.

  The restriction release file 8 includes a restriction release command in addition to the information FB. Since the transmission data of the restriction release file 8 is also text data, the amount of data is small and the transmission burden is light. The e-mail contains a mail text.

In this e-mail text, the contents of the information FB excluding the software name, the purchase price, the type of PC that can be used, the number, etc. are not displayed as confidential matters. On the sender (copyright manager) side, the restriction release file 8 is attached to the mail and transmitted to the user. However, if a registration application for the function-limited software 1 is made by communication with a server computer via a site on the Internet, a predetermined display item is displayed on the home page after the confirmation of the registration application. Then, after the user operates the confirmation button, the restriction release file 8 may be attached to the mail and transmitted, or the data may be automatically transmitted to the user. The received restriction release file 8 is automatically saved under a predetermined directory.
In addition, regarding the registration application sent by mail, the restriction release file 8 and a text sentence in which a part of the contents of the information FB is written and saved are stored on the flexible disk and mailed. However, the text sentence may be output on paper.

Next, a method for releasing the function restriction of the software with function restriction 1 will be described with reference to the flowchart of FIG.
The flowchart portion of FIG. 5 is incorporated in the identification software 5, for example. In FIG. 5, in step 51, the user saves the restriction release file 8 after receiving the electronic mail transmitted from the copyright manager or the like. However, the restriction release file 8 may be automatically saved when communicating with the server computer via a site on the Internet. It is also desirable to save the flexible disk when it is sent by mail. In step 53, the function-limited software 1 is executed.

  Next, in step 55, for example, it is determined whether or not the file F1 exists in the Windows (R) directory of the basic drive. If the file F1 exists, the process proceeds to step 57. In step 57, the user is made to select the restriction release file 8, or the drive or directory in which the restriction release file 8 exists. When the restriction release file 8 is automatically saved in a predetermined directory or the like, it can be automatically read.

  When applying for registration by mail, if the flexible disk is not in the flexible disk drive, a flexible disk is required. However, the restriction release file 8 may be automatically searched. In step 59, it is determined whether or not the content of the file F1 matches the content of the information FB of the restriction release file 8.

  However, when performing this comparison, it is conceivable that the function-restricted software 1 is uninstalled after the previous registration application work, and then the function-restricted software 1 is reinstalled. At this time, the installation drive and directory may be installed differently from the file F1.

  Therefore, when such uninstallation is performed, directory information in which the software 1 with function restriction is installed is not compared. For this reason, the uninstall information of the function-limited software 1 is described in the file F1. However, when the installation drive and directory are not used as information for specifying the personal computer to be used, the uninstallation information is not necessary.

  If the contents of the file F1 and the contents of the information FB in the restriction release file 8 match, it is determined in step 61 that the personal computer is the personal computer at the time of registration application of the registrant. In addition, when communicating with a server computer via a site on the Internet, such a determination can be made on the server side. It is desirable to confirm that the software name extracted from the function-limited software 1 matches the software name existing in the information FB. In addition, it is possible to confirm the coincidence with the file name, the capacity of the execution file for start-up and the update date and time. Thereafter, in step 63, a restriction release command is executed to release the restriction of the software 1 with function restriction. The execution of the restriction release command is determined, for example, based on whether or not the restriction release instruction of the information FB matches a restriction release instruction previously incorporated in the function-limited software 1.

  Before the registration application, the user confirms the trial using the trial version software, and the software 1 with function restriction is simultaneously sent from the copyright manager or the like when the restriction release file 8 is transmitted after the registration application. The function-limited software 1 can be associated with the trial version software by overwriting files in the same personal computer as the trial version software (installing files in the same directory or installing the function-limited software 1). After installation, it is possible to release the function restriction by a restriction release command (for example, a password).

  However, instead of this coincidence determination, what is selected as the contents of the information FB from the contents of the file F1, what is the order of description of the items, and the contents of the information FB are divided according to predetermined rules. It is also possible to eliminate the restriction release command by determining rules in advance between the software 1 with function restriction and the copyright manager side, for example, by making information mixed, and making a comparison.

  Moreover, you may use combining such judgment. In this way, codes that are computerized under predetermined rules are difficult to discriminate even if they are output as data outside the personal computer, and are safe from the point of information leakage.

  In step 65, even after the registration application, the function-restricted software 1 may be uninstalled and reinstalled, so that unnecessary history information (data after *) is deleted from the contents of the file F1. . In step 67, the software can be started in the state of software with no function restriction (hereinafter referred to as software 9 without function restriction).

  Next, the case where the file F1 does not exist in step 55 will be described. At this time, an error is displayed in step 69, and the process ends without releasing the function restriction. If the content of the file F1 does not match the content of the information FB of the restriction release file 8 in step 59, the process proceeds to step 71 and it is automatically determined whether or not the OS is reinstalled.

  The determination at this time is performed as follows, for example. When the OS is reinstalled, the date and time of the Windows (R) directory of the basic drive and a plurality of setting files are newly set. On the other hand, from the content of the information FB in the restriction release file 8, the date, time, minute, and second of execution when the software 1 with function restriction is installed is known.

  This date and time is compared with the date and time of the Windows (R) directory of the basic drive. If the date / time of the Windows (R) directory or the like is newer than the year / month / day / hour / minute / second of the execution of the installation of the function-limited software 1, the OS has been reinstalled after the registration application. On the other hand, if it is old, the OS is not reinstalled.

  If the OS has been reinstalled, the process proceeds to step 73. On the other hand, if the OS has not been reinstalled, it is not a personal computer when the registrant himself / herself applied for registration. Display and exit without releasing the function restriction.

In step 73, the information unique to the personal computer is compared between the contents of the file F1 and the information FB of the restriction release file 8. If the comparison results match, it is determined that the OS has been reinstalled on the same personal computer as the registration application, and the process proceeds to step 75. On the other hand, if the comparison results do not match, the process proceeds to step 69 to display an error, and the process ends without releasing the function restriction.
In addition, a plurality of data (for example, model numbers, serial numbers of hard disks and motherboards) can be acquired as information unique to the personal computer, and these data (if these data are changed, of these data) If it is possible to authenticate the personal computer used by the person almost certainly, it is possible to eliminate the need to re-install the OS in step 71.

  In step 75, a request is made to insert the file Fa stored for backup stored on a flexible disk or the like into a flexible disk drive or the like. In step 77, the name of the file is changed to F1 and the file is saved under the Windows (R) directory. However, the file F1 may be downloaded from a site on the Internet and stored.

Thereafter, in step 79, the UP code, which is the fact that the OS has been reinstalled, is stored in the file F1. Then, it progresses to step 61 and it determines with a registrant himself and performs the subsequent processes. This is because it is determined that the reinstallation of the OS is performed only in an emergency. In such a case, the file F1 is lost at the time of the registration application, and some kind of treatment is necessary.
In addition, multiple data can be acquired as information unique to the personal computer, and authentication of the personal computer used by the person can be done with these data (if these data are changed, some of these data) If it can be performed almost certainly, the following method can be used instead of resetting the file F1 via a flexible disk or the Internet.
First, an OS reset button (not shown) is pressed. At this time, a plurality of data as information unique to the personal computer is quantified. For quantification, for example, the number is left as it is, and the sign is digitized based on a predetermined function. For example, a function can be assigned by assigning 1 to a and assigning 2 to b. Each of the quantified numbers is subjected to a predetermined calculation such as addition to generate one unique information key. Since this unique information key is displayed on the screen, the user can contact the copyright manager with the unique information key. Contact may be made by telephone or FAX. The copyright manager adds a restriction release command and a password to be described later to this unique information key. Thereafter, encryption is performed based on the unique information key to generate a new password.
This encrypted data is notified to the user. The user inputs this data on a predetermined screen of the software 1 with function restriction or copyright protection software described later. The function-limited software 1 or the like decrypts the input data based on the unique information key. If the information unique to the personal computer matches, the restriction release command and the password are stored in the file F1 in association with the function-limited software 1 or the like.
As described above, even if the personal computer is not connected to the Internet and the file F1 is not backed up, the re-setup can be easily dealt with by telephone or the like.

Next, an intention display method for use with a plurality of (N) personal computers at the time of registration application will be described with reference to the flowchart of FIG.
Note that the same elements as those in FIG.

  In FIG. 6, in step 91, it is required to insert a flexible disk into a predetermined flexible disk drive. It is desirable to use the same flexible disk as that used for the backup described in FIG.

  This is to minimize the number of flexible disks to be used. In step 93, the contents of the file FN (F1, F2, F3...) Are stored as a file Fa on this flexible disk. The content of the file Fa is preferably encrypted. When a network is constructed, the contents of the file FN may be stored in a predetermined file stored in a specific personal computer (for example, a personal computer connected to the Internet) without using a flexible disk. Moreover, it is also possible to preserve | save via the site on the internet, the specific memory | storage means provided on the internet, etc. In the case of going through a site on the Internet, since it is necessary to connect to the Internet for each personal computer, the files F1, F2, F3,.

  In step 95, an inquiry is made as to whether or not there is another personal computer that wants to use the software 1 with function restriction. If the YES button is clicked, the registration completion work on the personal computer is canceled or terminated without setting a selection completion key in the flexible disk, which means completion of selection, in step 97.

  If you want to apply for the registration of the second personal computer regarding the use of the software 1 with this function restriction, return to Step 1. Function-limited software 1 is also installed on the second personal computer. In step 91, the same flexible disk as that used for the first unit is required.

  In step 93, the contents of the file F2 are additionally written in the file Fa on the flexible disk. However, you may preserve | save in the state made independent for every file FN (F1, F2, F3 ...). If it is desired to use another personal computer, the YES button is clicked in step 95. Click the NO button if there are no more personal computers you want to use. At this time, in step 99, the selection completion key is stored in the file Fa, flexible disk, or the like.

  Next, in step 11, the personal computer connected to the Internet is turned on, the function-limited software 1 is activated, and the registration application icon is clicked. Subsequently, in step 101, the same flexible disk as used in step 91 is requested. If the selection completion key exists in the file Fa or flexible disk in step 103, the number of personal computers selected in step 105 is added up.

In step 107, the total amount is calculated. The total amount is calculated based on an amount determined in advance according to the degree of increase in the number of units, for example, as the number of units increases, the price per unit is reduced or the price is set in stages. Alternatively, the relationship between the increase in the number and the price may be calculated as an approximate curve.
Thereafter, the processing of step 13 to step 23 is subsequently performed. If there is no selection completion key, there are still computers to be registered, so the process is repeated from step 1. At this time, in the case of a PC for which registration has already been applied, it is desirable to send a message “already registered”. When applying for registration, as described above, communication with the server computer may be performed via a site on the Internet.

  The same process is performed when the mail registration application icon is clicked in step 25. That is, if the same flexible disk is requested in step 101 and the selection completion key exists in this flexible disk in step 103, the number of personal computers selected in step 105 is added up. In step 107, the total amount is calculated. Subsequently, the processing of step 27 to step 37 is performed. If there is no selection completion key, the process is repeated from step 1.

  Note that the method of releasing the function restriction of the software 1 with function restriction is the same as the flowchart of FIG.

Next, a method for starting the software 9 without function restriction will be described.
In FIG. 7, in step 111, the function-unlimited software 9 is activated. If the file FN (F1, F2, F3...) Does not exist in step 113, there is a high possibility that the function-unrestricted software 9 has been copied from another personal computer. 9 is restricted again.

  If the file FN exists, the process proceeds to step 117 and it is determined whether or not an UP code exists in the file FN. If the UP code does not exist, it is determined that the OS has not been reinstalled, and the contents of the file FN are compared with personal computer-specific information and OS information in step 119. The information unique to the personal computer and the OS information are information acquired from the personal computer each time.

  The comparison with the information unique to the personal computer and the OS information is for accurately determining whether or not the personal computer is used in the registration application. If they do not match, it is not used on a registered personal computer, so the function restriction of the software 9 without function restriction is restricted again at step 115. If the comparison results match, in step 121, the function-unlimited software 9 is used as it is.

  On the other hand, if the UP code is present in step 117, the OS has been reinstalled, so in step 123, only the information unique to the personal computer is used and compared with the contents of the file FN. This is because the OS information may be changed by re-installing the OS. If the comparison results match, in step 121, the function-unlimited software 9 is used as it is.

  By adopting such a function-unlimited software 9 activation method, both the file FN and the non-function-restricted software 9 can be copied from a registered personal computer and used illegally on other computers, or there is no functional restriction. This is effective when copying only the software 9 and trying to use it illegally on another personal computer.

  Next, a method for enabling the software 9 without function restriction to be used by moving between personal computers will be described.

  FIG. 8 and FIG. 9 show flowcharts, and FIG. 10 shows the data flow corresponding thereto. Now, it is assumed that the data shown in FIG. However, for the sake of simplicity, the data of the file F1 is shown only in terms of installation time and personal computer type (see step (1) in FIG. 10).

  The personal computer 1 is in a state of software 9 with no function restriction. The personal computer 2 is installed with the software 1 with function restriction and is in a state where the function restriction is applied. As a next step from this state, the personal computer 2 is set to an unrestricted state and the personal computer 1 is function-restricted.

  First, operations and processing on the personal computer 2 side will be described. In FIG. 8, in step 201, the function-limited software 1 of the personal computer 2 is activated. In step 203, the movement application button 31 is clicked from the screen of the software 1 with function restriction of the personal computer 2.

  At this time, as shown in FIG. 10, the personal computer 2 includes data consisting of a click time T1S (S is a code indicating that the application has been made) when the movement application button 31 is clicked, and a model PC2S of the personal computer 2. Is created (step (1) in FIG. 10). This data is created only once, and is not created even if the movement application button 31 is clicked thereafter. For simplification of explanation, the model of the personal computer 2 is shown only as PC2, but for example, if a manufacturing number can be obtained, it is desirable that the number is also added to the model of the personal computer 2. Even when the serial number cannot be obtained, for example, it is desirable that the time T1 when the movement application button 31 is clicked is added to the model of the personal computer 2 (hereinafter the same).

  The created data is overwritten on the data portion corresponding to the software 1 with function restriction in the file FN under the Windows (R) directory of the personal computer 2, for example. Therefore, the initial data at the time of installation as shown in FIG. 2 does not remain, and only T1S and PC2S are stored in the file FN.

  In step 205, the data storage location is inquired and is selected. However, a storage location may be set in advance. This selection is either a movable medium such as a flexible disk, or any location in the hard disk if it is desired to move between networked personal computers. It may be via a site on the Internet or a specific storage means provided on the Internet. Data T1S and PC2S are stored in the storage location selected in step 207.

  Next, operations and processing on the personal computer 1 side will be described. In step 209 of FIG. 9, the function-limited software 9 of the personal computer 1 is activated. The personal computer 1 displays, for example, the personal computer 1 such as the personal computer 1 on the screen in order to indicate that the personal computer 1 is in a function-free state (step (1) in FIG. 10). In step 211, the movement acceptance button 33 is clicked from the screen (step (2) in FIG. 10). In step 213, the data storage location is inquired, so it is selected. However, a storage location may be set in advance. When saved via a site on the Internet, the server can automatically authenticate the person based on the exchanged cookie data and extract the saved file. Password and user I.D. D. And a password or user I.I. as described in the sixth embodiment of the present invention. D. The saved file may be extracted by automatic transmission and determination such as.

  In step 215, the data stored in step 207 is read and added to the data in file F1. For example, PC2, which is the type of the personal computer 2 that has been accepted for movement in step 217, is displayed on the personal computer 1 (step (2) in FIG. 10). At this time, the display of PC1 (without function restriction) and the display of PC2 (with function restriction) are distinguished by color coding or the like.

  Both the PC1 and PC2 are displayed as switches. Data is accumulated as a history in time series. It should be noted that the movement application process in FIG. 8 and the movement acceptance process in FIG. 9 may be repeated to display a larger number of switches. In this case, the destination can be selected from the plurality of personal computers. It is desirable that all information on these personal computers is registered on the site of the copyright manager.

  Next, operations and processing on the source personal computer will be described. In step 231 of FIG. 11, the destination personal computer is selected. For example, in step (3) of FIG. 10, the switch of PC 2 that is the movement destination is clicked on personal computer 1.

  Thereafter, in step 233, a flexible disk or the like is requested. As this flexible disk, the above-described flexible disk may be used, or an independent disk may be used. If it is desired to move between computers connected to a network, it may be located anywhere in the hard disk. When saved via a site on the Internet, it is possible to automatically authenticate the person on the server side from the exchanged cookie data and extract the saved file.

  In step 235, PC1-PC2R (R is a release request signal) indicating that the time T2 when the switch of PC2 is clicked and the function restriction release is transferred from the personal computer 1 to the personal computer 2 is additionally described in the file F1. The same data is stored on a flexible disk or the like. At this time, it is stored as a reference file Q1 on a flexible disk or the like. This reference file Q1 is transmitted through a site on the Internet. In step 237, the software 9 without function restriction of the source personal computer (personal computer 1) is set with function restriction and is changed to software 1 with function restriction.

Next, operations and processing on the destination personal computer will be described.
In FIG. 12, in step 251, the function-limited software 1 of the personal computer 2 is activated. In step 253, the use personal computer button 35 in the screen of the software 1 with function restriction is clicked (step (4) in FIG. 10). In step 255, the data storage location is selected. In the case of a flexible disk, a flexible disk is required. When saved via a site on the Internet, the server can automatically authenticate the person from the exchanged cookie data, extract the reference file Q1, and download it.

  In step 257, the data of the reference file Q1 is read from a flexible disk or the like. At this time, as shown in step (4) of FIG. 10, all of the personal computers PC1 and PCs to which S is applied from the contents of the reference file Q1 (PC1 in the case of step (4) of FIG. 10) are registered. PC2) is displayed. At this time, the PC 1 that is the movement source personal computer and the PC 2 that is the movement destination may be displayed by color coding or the like from the PC 1 -PC 2 R.

  Next, it is determined from the data read in step 259 whether or not the other personal computer other than the personal computer has its function restricted. In the case of step (3) in FIG. 10, since PC1 is restricted by PC1-PC2R, it is determined YES and the process proceeds to step 261. On the other hand, if NO is determined, the function restriction is not released in step 260.

  In step 261, it is determined whether or not the release request signal R is directed to the personal computer. In this case, since it is directed to the PC 2, it is determined YES and the process proceeds to Step 263. On the other hand, if NO is determined, the function restriction is not released in step 260.

  In step 263, it is determined whether or not the data of the file FN of the personal computer is included in the data read from the flexible disk or the like in step 257. In the case of FIG. 10, since only T1S and PC2S are stored in the file FN of the personal computer 2, they are included in the data of step (3) read from the flexible disk or the like. Therefore, it is determined as YES and the process proceeds to Step 265. On the other hand, if NO is determined, the function restriction is not released in step 260.

  In step 265, it is determined whether or not the release request signal R is newer than the data of the personal computer. Whether or not it is a new release request signal R is determined in the data accumulation order. However, if it is assumed that there is no difference in setting time between personal computers, it may be determined by time T. A reference number indicating the data accumulation order may be assigned, and the determination may be made based on the reference number. Or you may judge combining these.

  If it is determined that the signal is not the new release request signal R, “Old movement command” is displayed in step 267, and the function restriction is not released in step 260. In the case of a new release request signal R, the process proceeds to step 269. In step 269, it is determined whether or not the latest release request signal R is not yet received.

  If it has been accepted, “already accepted” is displayed in step 271 and the function restriction is not released in step 260. If not received, the process proceeds to step 273, and the data of the reference file Q1 such as a flexible disk is overwritten and updated on the file FN of the destination personal computer.

  Thereafter, in step 275, the restriction on the software 1 with function restriction is released. In step 277, the cancellation request signal R is deleted from the data of the flexible disk or the like and the file FN. Thereafter, in step 279, the released personal computer is displayed by color coding or the like.

  As described above, the function restriction on the personal computer 2 of the software 1 with function restriction is released, and the movement of the used personal computer is completed. As a result, for example, even when a new personal computer is purchased, the personal computer can be easily moved from the personal computer before purchase to the personal computer after purchase by performing the main movement operation.

  Further, while maintaining the number registered with the copyright manager, it can be used on a personal computer different from the registered personal computer. Therefore, between your home and office, between your company's computers, between computers connected by a network, between computers that can use the Internet, between computers that can use the Internet and computers that cannot use the Internet. The right to use can be transferred between each other.

  If the function restriction of the software 1 with function restriction is to be released again on the personal computer 1 side, the personal computer 2 is selected as the destination personal computer PC1 in step 231 of FIG. At this time, a history is stored in the file FN in the personal computer 2 as shown in step (5) in FIG. The data of the reference file Q1 is overwritten and updated on a flexible disk or the like. The data of the reference file Q1 is text data, has a small capacity, and can be stored together with other data on a single flexible disk or the like, which is convenient. The data of the same reference file Q1 need not always be overwritten and updated, and may be newly stored. Thereafter, the same processing as shown in FIGS. 11 and 12 is repeated. Moreover, the movement application and the movement acceptance process need only be performed once at the beginning. After that, it is easy because the work is performed between the movement source and the movement destination.

  Further, when the personal computer 2 is in the state of the software 9 without function restriction, the same applies to the case where it is desired to release the functional restriction of the software 1 with function restriction on the personal computer 3 as the third personal computer. In step 203 in FIG. 8, the movement application button 31 is clicked on the personal computer 3. At this time, only the click time T4S of the movement application button 31 and the type PC3S of the personal computer 3 are stored in the file FM under the Windows (R) directory. This data is also stored on a flexible disk or the like.

Thereafter, the flexible disk or the like is moved, and the movement acceptance button 33 is clicked on the personal computer 2. At this time, the data of T4S and PC3S are added to the existing data. By this work, PC1, PC2, and PC3 are displayed on the personal computer 2 as switches, and a color-coded display is displayed indicating that PC2 is currently releasing the function restriction.

  Therefore, PC3 is clicked in step 231 of FIG. To the file FN in the personal computer 2, T5 and PC2-PC3R are added on top of the data of T4S and PC3S. The same data is also stored on the requested flexible disk or the like.

  In this way, the history is accumulated and stored one after another. The history is added because the copied data becomes old data and cannot be used every time the history is added even if the contents of the flexible disk or the like are copied and saved. The function-limited software 9 of the personal computer 2 is function-restricted and becomes software 1 with function restriction.

  Subsequently, the work is transferred to the personal computer 3, and the used personal computer button 35 is clicked in step 253 of FIG. Thereafter, this flexible disk or the like is selected. As described above, in step 279, it is displayed by color that the PC 3 is releasing the function restriction. The function restriction of the software 1 with function restriction in the personal computer 3 is released, and the software 9 without function restriction is obtained.

  If the flexible disk is destroyed or lost, or the reference file Q1 is deleted, the reference file Q1 to be updated does not exist in step 233 when the moving operation is performed, so the reference file Q1 is newly created. Is done.

  Further, it can be confirmed from any personal computer by clicking on the personal computer button 35 in step 253 in FIG. 12 and selecting this flexible disk or the like to determine which personal computer is currently releasing the function restriction. However, if the reference file Q1 is automatically saved in a predetermined directory so that it can be referred to, the operation of selecting a flexible disk or the like is not necessary.

  Further, in FIG. 8 and FIG. 9, the movement application button 31 is clicked on the movement destination personal computer, and the movement acceptance button 33 is clicked on the movement source personal computer. However, a transfer application is made on the source PC, the function 9 of the source PC without function restriction is restricted, the data of the file FN is saved in the reference file Q1 such as a flexible disk, and the transfer is accepted on the destination PC for reference. The function restriction of the software 1 with function restriction may be released by referring to the file Q1.

Next, a data arrangement method when the data amount of the reference file Q1 such as a flexible disk increases will be described.
Since the reference file Q1 is only text data, a considerable amount of history can be saved. However, since other data files may exist on the same flexible disk, the data can be organized.

  In the software 9 with no function restriction, when data organization is necessary, the data organization button 37 is clicked. By this click, the contents of the file FN are organized into the data shown in FIG. At this time, the reference file Q1 may be arranged at the same time.

  In FIG. 13, T0 and PC1 which are the first data describe the data shown in FIG. 2 in a simplified manner as described in the step (1) of FIG. The first data, the data with S applied for movement, and the last movement command are left, and the intermediate data is deleted. The rearrangement code A is assigned to each personal computer (PCs 1 to 3 in the example of FIG. 13). However, this personal computer (PC 4 in the example of FIG. 13) that has been subjected to data rearrangement is not given the rearrangement code A.

  Further, the flowchart corresponding to FIG. 12 is changed as shown in FIG. That is, when it is determined in step 261 that the release request signal R is directed to the personal computer, the process proceeds to step 281 and it is determined whether or not the rearrangement code A directed to the personal computer exists.

  If the reference code A exists, the process proceeds to step 283, and the reference code A directed to the personal computer is deleted. Then, the process proceeds to step 265. For this reason, the process of step 263 is not performed. On the other hand, if the rearrangement code A does not exist, the process of step 263 is performed.

  As a result, each personal computer, flexible disk, and the like are automatically organized as the function restriction release personal computer is moved.

  Next, after performing the process in Fig. 11 to restrict the functions of a computer that is currently in use for use on another computer, the user wants to use this computer again without moving to another computer. explain.

  At this time, the used personal computer button 35 is clicked in step 253 of FIG. 14, and then this flexible disk or the like is selected. In step 259, it is determined that this personal computer is restricted, not another personal computer, so that functional restriction is continued in step 260.

  In this state, for example, the PCM switch which is the personal computer is clicked from the displayed personal computers PC1, PC2,..., PCM,. At this time, after it is determined in the example of FIG. 15 that the personal computer of the latest history information is PCM, T9 and PCM-PCN R are deleted from the reference file Q1 and the file FN.

  The same applies when the flexible disk or file is destroyed, lost, or deleted before moving to another computer. Returning to the movement source personal computer, the use personal computer button 35 is clicked in step 253 of FIG. 14, and then this flexible disk or the like is selected. In this state, for example, the PCM switch that is the personal computer is clicked. When the reference file Q1 does not exist on the flexible disk or the like, data is saved from the file FN.

  Next, FIG. 16 shows a method for activating the function restriction-free software 9 in consideration of moving the function restriction release between personal computers. The same elements as those in FIG. 7 are denoted by the same reference numerals, and the description thereof is omitted.

  In FIG. 16, in step 291, the destination personal computer is extracted from the latest movement history data in the file FN. For example, PCN is extracted in the example of PCM-PCN in FIG. This data is compared with information specific to the personal computer (eg, PCN) at step 123. If they match, the function-unlimited software 9 is executed in step 121 as it is. If they do not coincide with each other, the function of the software 9 without function restriction is restricted in step 115.

  The reference file Q1 and the file FN may be protected with a password, for example. The contents are preferably encrypted.

  Next, a case where the software 9 without function restriction is uninstalled on the destination personal computer will be described. In FIG. 17, the software 1 with function restriction is reinstalled in step 251. At this time, since the file FN already exists, it is not overwritten and updated.

As a premise, when the uninstall software is provided as an execution file or the like, the time T _UN when the execution file was started and the uninstall information UN code that is the fact of execution are recorded in the file FN. .

In step 301, it is determined whether or not a UN code exists in the file FN. If it exists, the process proceeds to step 303, and the latest movement history data is extracted from the file FN. For example, the PCM-PCN in FIG. 13 is extracted. In step 305, it is determined whether or not the UN code is generated after the latest movement history data. Comparison of this time is performed between the PCM-PCN T9 and the time is the time of occurrence of T _UN in FIG.

  If the UN code is generated after the latest movement history data, it is determined that the function-restricted software 1 is uninstalled and then reinstalled after the function restriction of the destination personal computer is released. it can. Therefore, the process proceeds to step 259 to apply exceptions.

  This exception application is performed by simplifying the processing of FIG. 12 as follows. First, in step 259, it is determined whether or not other personal computers are restricted from the latest movement history data. If YES, it is determined in step 261 whether the object is directed to the personal computer. If it is for the personal computer, it can be determined that the personal computer has been used before the uninstallation, so the restriction is removed in step 275. If the determination result in step 259 and step 261 is NO, the function restriction is continued in step 260.

  On the other hand, if the UN code is not generated after the latest movement history data in step 305, it is determined that the uninstall has occurred in the past and is ignored, and the processing after step 253 in FIG. Is called.

If the uninstall software is not provided as an executable file or the like, it is determined whether or not the uninstall has been performed as follows. That is, as shown in FIG. 2, the installed fact is left in the file FN as a history. If there is a fact that it has been installed after the latest movement history data in step 307, it is determined that the uninstallation has been performed, and the processing from step 259 is performed.
Further, whether or not uninstallation has been performed may be determined as follows. After confirming that the OS has not been reinstalled, the date and time are obtained from the directory or the like where the function-restricted software 1 has been reinstalled. Then, this date / time is compared with the date / time of the latest movement history data existing in the file FN. If the date and time acquired from the directory or the like is newer than the date and time of the latest movement history data, it is determined that the function-unlimited software 9 has been uninstalled on the destination personal computer.

  Next, a case where the OS of the destination personal computer is reinstalled will be described. At this time, a countermeasure is taken as shown in FIG. Note that the same components as those in FIG. 14 are denoted by the same reference numerals and description thereof is omitted.

  First, in step 251, the function-limited software 1 is reinstalled. At this time, the file FN is newly created. In step 253, the personal computer button 35 is clicked, and then this flexible disk or the like is selected. In step 311, the latest movement history data (T9, PCM-PCN in the example of FIG. 13) is extracted from the reference file Q1.

  In step 313, it is determined whether or not the OS has been reinstalled after the latest movement history data T9. The automatic determination of whether or not the OS has been reinstalled is the same as the processing in step 71. If the OS has not been reinstalled after the latest movement history data, the same processing as step 259 in FIG. 14 is performed as usual.

  On the other hand, when the OS is reinstalled after the latest movement history data, it can be determined as an emergency. Therefore, the process proceeds to step 259 to apply exceptions. This exception application is performed by simplifying the processing of FIG. 14 as follows. If YES in both step 259 and step 261, the restriction is removed in step 275. In step 315, the data of the reference file Q1 is updated to the file FN.

  Note that, as another coping method when the OS of this destination personal computer is reinstalled, it is also possible to return the state of all personal computers to the initial state when registration is completed. That is, if the OS is reinstalled in step 313 in FIG. 18, the history data of the file FN and the reference file Q1 is deleted, and the OS is reinstalled in the reference file Q1 on the destination personal computer. The UP code, which is a fact that has been broken, is stored.

  This UP code is detected by another personal computer, and history data is deleted when the UP code is not supported. After deletion, the UP code corresponding to each personal computer is processed. However, only the personal computer at the time of registration leaves the initial data of FIG. 2 and deletes other data.

  Next, a case where the OS is reinstalled on a personal computer other than the destination personal computer will be described. This can be dealt with by re-installing the function-restricted software 1 and then performing the transfer application in FIG. 8 and the transfer acceptance process in FIG.

  Next, a description will be given of a method of releasing the function restriction in units of personal computers or a group of a plurality of software 9 having no function restriction.

  In carrying out this method, it is desirable to store initial data and history data at the time of registration of a plurality of software 9 without function restriction (software 1 with function restriction) as one file FN. Alternatively, it is necessary to know in which file the history data and the like of the grouped function-unlimited software 9 (functionally restricted software 1) is stored in advance.

  As shown in FIG. 19A, the history of software 1 to software 3, which is software 1 with function restriction, is stored in the file FN of the personal computer PCJ. The software 1 and the software 3 are in a state in which the function restriction is released by the personal computer PCJ. The function restriction of the software 2 is released in another personal computer PCM, and the function restriction is applied in the personal computer PCJ.

  In this state, the move button 39 is clicked for each group from the screen of one function-unrestricted software 9 (step 321 in FIG. 20). In step 323, the software whose destination is the personal computer is selected by this click. In the example of FIG. 19A, software 1 and software 3 are selected.

  Since a selectable personal computer PC is displayed as a switch, in step 325, one of the personal computers as the movement destination is selected. For example, the personal computer PCX is selected. By this selection, the history of each software becomes as shown in FIG. 19B, and the latest movement history data PCJ-PCX R is added to software 1 and software 3. At this time, since the software 2 is used in a personal computer PCM other than the personal computer PCX, it is not changed.

  Note that T11 of software 1 and T8 of software 3 in FIG. 19B are the same data if they are time information, and are cumulative numbers for each software if they are cumulative numbers. In the case of a combination of time information and an accumulated number, the accumulated number portion is different data. When it is assumed that the time data is different for each personal computer, a combination of time information and a cumulative number is desirable.

  In step 326, the latest movement history data PCJ-PCX R is assigned a code G indicating that the movement is performed in groups.

  At step 327, the data storage location is inquired and is selected. This selection is either a flexible disk or a location on the hard disk or a site on the Internet if it is desired to move between networked personal computers. Except for the software 2, the history of the file FN is stored in the storage location selected in step 329. In step 331, the functions of the software 1 and software 3 in the personal computer PCJ are limited.

  Next, it moves to the personal computer PCX of the movement destination and clicks the movement button 39 for each group from the screen of one software 1 with function restriction (step 341 in FIG. 21). In step 253, the personal computer button 35 in the screen of the software 1 with function restriction is clicked. In step 255, the data storage location is selected. However, the data storage location can be set in advance.

  In the case of a flexible disk, a flexible disk is required. In step 257, the data stored in step 329 is read from a flexible disk or the like. A group batch movement code G is detected from the data read in step 343.

  When the group collective movement code G is detected, the processing after step 259 shown in FIG. For example, according to the stored data in step 329, the processing from step 259 onward for software 1 and software 3 is performed.

  Then, for each function-limited software 1, in step 275, instead of releasing the restriction, if all the determination results in steps 259 to 269 are YES, the restriction release key is set together with the group batch movement code G of the file FX. Record for software 1 and software 3. The above processing is performed at once for all the function-restricted software 1 that has been moved in a state where each function-restricted software 1 is not executed.

  When the function-restricted software 1 is executed in step 251, it is determined whether or not the group batch movement code G and the restriction release key exist. If they exist, the jump restriction is canceled in step 275. Do. After the cancellation, the group batch movement code G and the limit release key are deleted. On the other hand, if it does not exist, the processing from step 253 is performed according to FIG.

  Note that even when the group is moved collectively in FIG. 20, the function restriction release processing is not performed for all software 1 with function restriction at once as in the process of FIG. 21, but as shown in FIG. The restriction may be released for each software 1 with function restriction. In this case, the process of FIG. 12 is repeated for each function-limited software 1. If the group collective movement code G is not detected in step 343, an error is displayed in step 347.

  For each function-restricted software 1, the following processing is performed to release the function restriction. In the process of FIG. 14, a step 254 is provided between the step 253 and the step 255 to determine whether or not the group batch movement code G is detected. If detected, the process of step 255 is not performed. At this time, instead of step 257, the data is read from the history data of the function-limited software 1 in which the file names in the file Fx match. Thereafter, the processing after step 259 is performed.

  In the first embodiment of the present invention, it has been described that the function restriction of the software 1 with function restriction is released or restricted according to the conditions. However, the normal software 11 that is not originally provided with the function restriction is restricted with a password or the like. It is also possible to release and release. In this case, a password is also given by the copyright manager as the information FB of the restriction release file 8. This password is also stored in the history data of the file FN and the reference file Q1.

  Then, for example, step 111 in FIG. Step 121 can be executed by automatically inputting a password or the like, and the function limitation of step 115 can be dealt with by not administering a password or the like. Similarly, step 237 in FIG. 11 can cope with the function restriction by not administering a password or the like.

  For example, the password may be entered by clicking on a password entry field and then clicking a password administration key button (not shown). At this time, the password of the normal software 11 is extracted from the file FN and is administered to the password input field. Furthermore, Step 251, Step 275, Step 260 in FIGS. 12 and 14, Step 111, Step 115 in FIG. 16, Step 251, Step 275, and Step 260 in FIG. 18 can be similarly changed.

Next, a second embodiment of the present invention will be described.
The second embodiment of the present invention is another aspect of the method described in the flowchart of FIG. 6 regarding the intention display method for use with a plurality (N) of personal computers at the time of registration application.

  In FIG. 6, a personal computer to be used is determined in advance and a registration application is made. However, in FIG. 22, a registration application is made for a plurality of (N) devices at once, and a personal computer to be used after registration is determined. However, for only one unit, a registration application is made in the same manner as described in FIGS. 1 to 4 of the first embodiment of the present invention. This is the case.

  In step 401 of FIG. 22, the restriction release file 8 includes use permission signals for N units. Next, in step 402, the function-limited software 1 is executed. In step 403, it is determined whether or not the file Fx (x = 1 to N) exists in, for example, the Windows (R) directory of the basic drive.

  If the file Fx exists, the process proceeds to step 404. If the file Fx does not exist, the process ends at step 415 or does not release the function restriction. In step 404, the user is made to select the restriction release file 8, or the drive or directory in which the restriction release file 8 exists.

  At this time, for example, when the flexible disk is not in the flexible disk drive, the flexible disk is required. In step 405, it is determined whether or not the file Fx is the file F1 used when only one application is applied at the time of registration application. When the file Fx is the file F1, the process proceeds to step 407, and it is determined whether or not the content of the file F1 matches the content of the information FB of the restriction release file 8.

  However, in performing this comparison, the case where the software 1 with function restriction is uninstalled after the previous registration operation and the software 1 with function restriction is reinstalled after that is the same as the case of FIG. is there.

  When the contents of the file F1 and the contents of the information FB of the restriction release file 8 match, it is determined that the personal computer at the time of registration is correct. Then, the process proceeds to step 409, where it is determined whether or not the function restriction of the software 1 with function restriction has already been released. If it has not been released yet, the process proceeds to step 411 to release the function restriction. Thereafter, in step 413, the function-unlimited software 9 is ready to be executed.

  On the other hand, when the function restriction of the software with function restriction 1 has already been released in step 409, the process ends in step 415.

  If it is determined in step 407 that the contents of the file F1 and the information FB of the restriction release file 8 do not match, the same processing as in steps 71 to 79 and 61 in FIG. If it is determined that it has been installed, then the restriction is removed in step 411.

  On the other hand, when Fx does not match F1 in step 405, the process proceeds to step 425, and the contents of the file Fx are compared with the contents of the file Fα (α = 2 to M: where M is the number of registered data). If the contents of the file Fx coincide with the contents of the file Fα, the personal computer has already been registered in step 427, and the process proceeds to step 415 and ends.

  When the contents of the file Fx and the contents of the file Fα do not match, the process proceeds to step 429, and it is determined whether M is N−1 or less. If M is less than or equal to N−1, there is still room for new registration, so the process proceeds to step 431, and an inquiry is made as to whether or not the currently used personal computer is registered as the M + 1th personal computer.

  When registering as the (M + 1) th personal computer, the YES button is pressed in step 433. If not registered as the (M + 1) th personal computer, the NO button is pressed in step 435 and the process ends in step 415. When the YES button is pressed in step 433, the process proceeds to step 437.

  In step 437, the latest installation information is selected from the history of the file F1M + 1 of the software 1 with function restriction. The directory information and the year / month / day / hour / minute / second of execution are marked with *. Thereafter, the installation information before this installation information is deleted from the history.

  In step 439, a backup request for the file F1M + 1 is displayed on the screen so that a storage disk can be inserted into the flexible disk drive or the like as a precaution. At this time, the file name is saved by changing the file name to FaM in order to hide the file location under the Windows (R) directory. The file FaM is associated with the software 9 without function restriction.

Thereafter, in step 411, the restriction is released. As a result, in step 413, the (M + 1) th function-restricted software 9 can be used.
As described above, the function-free software 9 can be used with a number of personal computers permitted in advance by the copyright holder with a simple operation.

Next, a third embodiment of the present invention will be described.
In the first embodiment and the second embodiment of the present invention, the case where the registration software portion 3 and the identification software 5 portion are used in combination with the software with function restriction 1 from the beginning is shown. On the other hand, in the third embodiment of the present invention, the registration software part 3 and the identification software 5 part are independent software (copyright protection software 51) and are used separately from the software 1 with function restriction. It is.

  An example of the display screen of the copyright protection software 51 according to the third embodiment of the present invention is shown in FIG. The left half of the screen is a tree display section 41 in which drives, directories, and files are shown in a tree structure in a hierarchical structure, for example, as in the Explorer screen of Microsoft (R).

  In this screen, an executable file for installation, a compressed file, a file for starting software, and the like are displayed. Further, the right half of the screen is an activation icon display unit 43 in which, for example, each software activation icon is shown. A button unit 45 is disposed above the tree display unit 41 and the startup icon display unit 43.

  Next, the operation of the copyright protection software 51 according to the third embodiment of the present invention will be described. In the third embodiment of the present invention, first, the software with function restriction 1 and the copyright protection software 51 supplied by a recording medium such as a download or CD-ROM are installed in a personal computer. Next, the copyright protection software 51 is activated to display the display screen of FIG.

The execution file for starting the software 1 with function restriction is selected from the tree display unit 41, and then an icon creation button (not shown) of the button unit 45 is clicked. At this time, an activation icon 43a of the copyright protection software 51 (for function-limited software 1) is created in the activation icon display unit 43. However, instead of the startup icon 43a, startup files may be listed in a table format or the like.
When the function-restricted software 1 and the copyright protection software 51 are installed, the activation icon 43a of the copyright protection software 51 (for the function-restricted software 1) is automatically displayed in the activation icon display 43 or the like. Is preferably produced.

  As a result, the activation icon 43a, the copyright protection software 51, and the activation execution files of the function-limited software 1 are associated with each other. Therefore, by clicking on the activation icon 43a, after the copyright protection software 51 determines whether or not it is used on a registered personal computer, the activation execution file of the software 1 with function restriction is executed. Etc. can be processed in order. This process is the same even when the function-restricted software 1 is document creation software, and a document icon is created as the activation icon 43a of the copyright protection software 51 (for function-restricted software 1). Then, by clicking this document icon, the copyright protection software 51 determines whether or not it is used on a registered personal computer, and then the document saved by the document creation software is displayed. Although it is possible to execute the activation execution file of the software 1 with function restriction alone, in this case, for example, as will be described later, for example, a password is not given and the function restriction is not removed.

  At this time, for example, a file name is extracted from the start execution file. This file name may be used as the name of the start icon 43a. And the file F1 of FIG. 2 is produced. The file name is the software name, and the execution date / time / minute / second is, for example, the click time of the icon creation button. It also detects and records the directory where the startup executable file exists.

  Since the click time and directory are recorded under the same function-restricted software 1, even when the same function-restricted software 1 is upgraded, for example, registration application information made at the first time can be referred to It is. PC-specific information and OS information are recorded in the same way.

  Note that the activation icon 43a of the copyright protection software 51 (for the function-restricted software 1) can be registered in the start menu, startup, and desktop by selection in option setting. The same function as the activation icon 43a of the activation icon display unit 43 can also be obtained by activating the activation icon 43a registered therein.

  In addition to the file name, the capacity and update date and time of the start execution file may be recorded as information for specifying the function-limited software 1. You may make it take the log | history of such information.

  In the flowchart of FIG. 3, the registration application button 11, the e-mail registration application icon, the mail registration application icon, and the confirmation button are operated from the button unit 45. In step 1, after selecting the activation icon 43a of the copyright protection software 51 (for function-limited software 1), the registration application button 11 is clicked.

  In step 3, instead of the installation information, the icon creation button click time and the latest directory information of the startup execution file are selected. In addition, when it is desired to apply for registration of a plurality of software 1 with function restriction, the processing of Step 1 to Step 5 is repeated.

  In the present embodiment, the process of executing the software 1 with function restriction in step 53 of the flowchart of FIG. 5 is to click the execution button (not shown) of the button unit 45 after selecting the activation icon 43a. However, it can also be activated by double-clicking the activation icon 43a.

  In step 55, if it is determined that the file F1 exists, it is determined whether or not a restriction release key for the function-limited software 1 exists in the file F1. If the restriction release key already exists, the process jumps to step 117 in FIG. On the other hand, if there is no restriction release key, the process proceeds to step 57.

  Subsequently, when it is determined in step 61 that the user is the registrant by the determination in step 59, the process proceeds to step 63. In step 63, first, a restriction release key for the function restricted software 1 is assigned to the file F1. At this time, a password or the like is extracted from the information FB of the restriction release file 8 and stored in the file F1.

  The method of releasing the function restriction is performed as shown in FIG. 24, for example. However, as a premise of FIG. 24, it is assumed that a password or the like is added to the information FB of the restriction release file 8 of FIG. Considering the case where the same function-limited software 1 is upgraded, it is desirable to change the password every time the version is upgraded.

As a result, even when the upgraded function-limited software 1 is installed in the same directory, it is possible to perform processing such as applying different function restrictions for each version upgrade stage. Therefore, even in such a case, the registrant of the previous version can use the function of the previous version as it is.
When the upgraded function-limited software 1 is installed in a different directory, an item of the upgraded function-limited software 1 is newly added to the file F1. At this time, if the password or the like in the previous version can be used as it is, the copyright protection software 51 first confirms the presence of the previous version of the function-restricted software 1 in the file F1. Thereafter, the password or the like is copied from the information in the previous version of the function-limited software 1 item in the file F1 and added to the upgraded version of the function-limited software 1 item.
Further, it is assumed that the software 1 with function limitation is compared with a password or the like each time it is activated, and it is determined whether or not to cancel the limitation.

  In FIG. 24, in step 350, it is determined whether or not the restriction release key for the function-limited software 1 exists in the file FN. If it exists, the process proceeds to step 370 to determine whether or not the file Fβ already exists. If the file Fβ does not exist, the copyright protection software 51 creates the file Fβ in a predetermined directory or the like in step 351, and records the password in the file Fβ. In this case, if there is a password for each version upgrade, it is desirable to record all passwords in Fβ as a history. If the file Fβ already exists, it is possible that the file Fβ has been illegally copied. However, there may be a case in which the file Fβ remains without being deleted due to some cause of an abnormality in the system or the like. Therefore, the process is continued to the extent that a warning is issued for the first time. Thereafter, when the situation in which the file Fβ already exists is detected a plurality of times, the restriction may be continued in step 356.

  On the other hand, if there is no restriction release key in step 350, the process jumps to step 57 in FIG. 5 in step 354 to determine again whether or not the user is the registrant. Thereafter, in step 352, the start execution file is operated, and the software 1 with function restriction is automatically started.

  The function-limited software 1 first reads the password recorded in the file Fβ in step 353. If the password matches the password previously set in the function-restricted software 1 in step 355, the function-restricted software 1 is released in step 357 and becomes the non-function-restricted software 9.

In step 359, the file Fβ is immediately deleted to prevent leakage of this password. The password may be deleted from the file Fβ. However, this deletion may be performed when the copyright protection software 51 ends the copyright protection software 51 or when a predetermined time elapses after the password is assigned to the file Fβ. When the password match is not recognized at step 355, the software 1 with function restriction continues restriction at step 356.
The contents of the file FN in step 119 and step 123 can be compared with the information unique to the personal computer and the OS information after the software with function restriction 1 in step 352 is automatically started. It is. At this time, in order not to interfere with the use of the function-limited software 1, comparison processing is performed at a place where the CPU load factor is low, or the comparison timing is appropriately shifted from the activation timing of the function-limited software 1. It is desirable.

The result of the comparison is stored in the file F1 as a code, and this code is referred to when the next function-limited software 1 is automatically started. According to such a method, it is possible to shorten the time until the function-restricted software 1 is activated, because it is not necessary to extract information specific to the personal computer or OS information before the function-restricted software 1 is activated. Since the comparison process can be performed at a place unrelated to the startup time, a large number of points to be compared with the information unique to the personal computer and the OS information can be obtained. For this reason, the accuracy of comparison can be improved.
Further, this comparison may be performed only once a day, for example. In this case, the result code is stored in the file F1 together with the executed time. The copyright protection software 51 compares the current time with the stored execution time, and performs this comparison process if 24 hours have elapsed. The sign of the comparison result is referred to before starting each function-limited software 1. As a result, the time until each function-limited software 1 is activated can be shortened.
Furthermore, when a plurality of information unique to a personal computer is compared on the OS side and the result can be referred to, the time required for the comparison can be further shortened.
The above comparison processing can also be applied to the first embodiment of the present invention.

Prior to registration application, the user confirms the trial using the trial version software. Then, after the registration application, it is determined whether or not the content of the file F1 matches the content of the restriction release file 8 transmitted from the copyright manager or the like. If they match, the copyright protection software 51 gives a restriction release key to the file F1. Thereafter, the copyright protection software 51 may download the software 1 with function restriction from a copyright manager or the like when the restriction release key exists in the file F1. It is desirable to download the password at this time.
Alternatively, when a registration application is made, the software 1 with function restriction may be downloaded from a copyright manager or the like. At this time, the password and the restriction release key are also downloaded.

Furthermore, the restriction release file 8 is omitted, and information such as the contents of the restriction release file 8, the password, the restriction release key, etc. is recorded in the header part (property) of the software 1 with function restriction. Information such as the contents of the restriction release file 8, the password, and the restriction release key may be downloaded in the form of being embedded in the program. Even in this case, it is desirable that the copyright protection software 51 reads the watermark information and determines whether or not it matches the contents of the file F1.
The information is, for example, the file name of the software 1 with function restriction. However, author information, file capacity, function restriction contents, etc. may be added. According to the author information etc., the attribution of the copyright becomes clear. The digital watermark technique is a technique in which other information is embedded in digital information in a form that is not perceived by humans, and the embedded information can be taken out when necessary. Then, the embedded information is extracted based on the key information used at the time of embedding, and the embedded position information is created by a random number.

In order to embed watermark information in a program, for example, a blank existing between instructions in the program is used. When the number of blanks is one, information “0” is displayed. Define “1”. It is possible to embed information in the program by appropriately combining these pieces of information.
However, when downloading the function-restricted software 1, it is not necessary to download all the files of the function-restricted software 1, and only necessary files to be updated to the function-restricted software 1 may be downloaded. . The downloaded software 1 with restricted function is the same personal computer as the trial version software (overwriting files in the same directory, or associating addresses and the like with the trial version software when installing the software 1 with restricted function). It is preferable to perform the installation), and the function restriction may be released with a password under the above-described processing. Even when the software is updated to the function-restricted software 1 in this way, the activation process, the movement process, and the like are performed in the same manner as described above.

  Note that a part of the file of the function-restricted software 1 or the entire function-restricted software 1 is encrypted in advance by public key method (for example, RSA) or a common key method (for example, DES (Data Encryption Standard)) (or the like). Compression). When a part of the file is encrypted, it is desirable that this part corresponds to a function restriction part.

  The above-described password or the like is a secret key when the public key system is used for encryption and the function-limited software 1 is encrypted with the public key, while the common key system is used and the function-limited software 1 is used. Is encrypted with a common key, it is a common key. The relationship between the public key and the secret key is a key that is generated at the same time and has a certain close relationship, and data encrypted with the public key can be decrypted only by the secret key. Therefore, when a part of the file or the like is provided in advance by being encrypted with a public key in a recording medium such as a download site or a CD-ROM, the secret key is included in the information FB as a password or the like. On the other hand, when encrypted with the common key, the common key is included in the information FB as a password or the like. It is desirable that the public key (secret key), the common key, and the like differ for each function-limited software 1.

  For example, if the software 1 with function restriction is encrypted with a public key, the secret key is extracted from the information FB of the restriction release file 8 and stored in the file F1 in step 63 of FIG. In FIG. 24, the password recorded in the file Fβ in step 353 is a secret key. In step 355, the function-restricted software 1 is decrypted using this secret key as a key instead of determining whether the passwords match.

It is more desirable that the public key (secret key), the common key, and the like be different for each function-limited software 1 to be downloaded or for each CD-ROM. At this time, for example, the following processing is performed.
First, a serial number is assigned to each unit such as the software 1 with function restriction to be downloaded. The assigned serial number is stored in the database of the copyright management center. The serial number is stored in an attached file attached to each function-limited software 1. The attached file is downloaded to the user's personal computer when the software 1 with function restriction is downloaded. When a download request is made by the user (or when a CD-ROM or the like is created), a key is generated. For example, when a public key method is adopted, a public key and a secret key are generated. Based on this public key, a part of the file of the function-limited software 1 or the entire function-limited software 1 is first encrypted and downloaded to the user (or recorded on a CD-ROM) in this encrypted state. The The private key is stored along with the serial number in the copyright management center database.

  When installing the function-restricted software 1 on the user personal computer, the serial number is first saved in the file F1 from the attached file together with the software information and the like. When the user likes the trial and wants to formally register or purchase the function-restricted software 1, the user applies for registration via the copyright protection software 51. When applying for registration, the file F1 is transmitted to the copyright management center in step 19 of FIG. The copyright management center extracts the corresponding secret key from the database based on the serial number extracted from the received file F1. This secret key and serial number are included in the information FB of the restriction release file 8. If it is determined in step 61 of FIG. 5 that the personal computer is a personal computer at the time of registration application, a secret key is extracted from the information FB and stored for the serial number of the file F1. In FIG. 24, the password recorded in the file Fβ in step 353 is a secret key. In step 355, the function-restricted software 1 is decrypted using this secret key as a key instead of determining whether the passwords match.

  Next, when there is a function-restricted software 9 prepared separately from the function-restricted software 1 to be evaluated, and the user wants to formally register and purchase the function-restricted software 1 after evaluation. The case where the software 9 without function restriction is provided in the form of a download or a CD-ROM will be described.

  When the function-restricted software 1 is installed in the user personal computer, the software name, the product ID that is the product number of the software, and the like are stored in the file F1. When the user wants to obtain the software 9 with no function restriction, the user applies for registration through the copyright protection software 51. When applying for registration, the file F1 is transmitted to the copyright management center in step 19 of FIG. The copyright management center extracts the software 9 having no function restriction desired by the user from the product ID extracted from the received file F1. Thereafter, a part or the whole of the software 9 having no function restriction is encrypted. At the time of encryption, it is desirable to generate an encryption key based on personal computer specific information, OS information, system information, etc. extracted from the file F1. A key generation theoretical value a indicating the theoretical value for generating the encryption key may be defined. The key generation theoretical value a indicates a logical procedure for generating an encryption key as will be described in detail later.

  The key generation theoretical value a is stored in the database of the copyright management center and is included in the information FB of the restriction release file 8. The encrypted function-unlimited software 9 and the restriction release file 8 are sent to the user's personal computer via the Internet or the like. If it is determined in step 61 of FIG. 5 that the registrant is the personal computer at the time of registration application, the key generation theoretical value a is extracted from the information FB and stored for the software information in the file F1. In FIG. 24, when a password is administered to the file Fβ in step 351, personal computer specific information, OS information, system information, etc. are extracted from the file F1, and decrypted based on the key generation theoretical value a from these information. After the key is generated (a method for generating a decryption key based on the key generation theoretical value a will be described later), this decryption key is administered as a password. In step 355, the function-unlimited software 9 is decrypted using this decryption key as a key instead of determining whether the passwords match. The decrypted unrestricted software 9 is expanded on the memory and used. However, the information FB of the restriction release file 8 does not include the key generation theoretical value a, but the generated key (a secret key when the software 9 without function restriction is encrypted with a public key, In the case of encryption with a key, a common key) may be included. The generated key may not be generated based on personal computer specific information, OS information, system information, or the like.

  Next, another example of password comparison is shown. As shown in FIG. 29, in step 371, the copyright protection software 51 obtains the current date / time data from the personal computer. In step 351, this date / time data is added to the password, and then the data is administered to the file Fβ. On the other hand, the function-limited software 1 reads the password recorded in the file Fβ in step 353 and determines whether the passwords match in step 355. If the passwords match, the current date / time data is acquired from the personal computer at step 373. Thereafter, in step 375, the date / time data directly obtained from the personal computer is compared with the date / time data read from the file Fβ. If the time, particularly the second, is within a predetermined error range, the restriction is canceled in step 357 assuming that the function is normal. If the error range is exceeded, the process proceeds to step 356 and the restriction is continued.

  However, it is assumed that the startup time of the function-limited software 1 and the processing time required to exchange data via the file Fβ are somewhat different depending on the processing speed of the personal computer. Therefore, the processing time is estimated by detecting the type of personal computer, the type of CPU installed in the personal computer, the processing speed of the CPU, and the capacity of the installed memory, and the error range may be adjusted from this processing time. Good. The guess can be determined in advance through experiments or the like.

Further, the processing time may be estimated on the copyright protection software 51 side, and a predetermined amount of time may be added from the current date and time data acquired from the personal computer in step 371 to administer the data to the file Fβ. . As a result, the time error in step 375 can be made extremely small.
As described above, since it is considered to add date and time data that is a variable value to a password that is a fixed value, it is effective against illegal activities such as copying the file Fβ in advance.

Further, from the viewpoint of the fluctuation value, for example, a predetermined common key value is prepared on the copyright protection software 51 side and the function-restricted software 1 side, and the copyright protection software 51 and the function-restricted software 1 You may make it update this key value at the time of starting. The key value is preferably data having no regularity such as 2, 6, 15, 10, 50. At the first activation, 2 is added to the password. At the next startup, 6 is added to the password. The key value may be an M-sequence code or the like. The M-sequence code is a binary pseudorandom number sequence having a period of 2 ^P -1 (P is an appropriate positive integer) taking two values (0, 1, 1, -1, etc.). However, there may be a case where the data is inconsistent between the copyright protection software 51 side and the function-limited software 1 side due to an error or the like for some reason. In this case, the key value at that time is forced to match. However, if the discrepancy continues multiple times, the restriction continues at step 356.
It is desirable that these fluctuation values are also encrypted.

Even if the password is a fixed value, the copyright protection software 51 may sequentially administer each digit of the password to the file Fβ. The function-limited software 1 reads each digit of the password recorded in the file Fβ. It is desirable that a start code be added at the beginning of the password and an end code be added at the end of the password. This also makes it possible to prevent the entire password from being leaked or to prevent fraud.
Further, when one digit of the password can be read on the function-limited software 1 side, the reception confirmation code may be recorded in the file Fβ from the function-limited software 1 side. When this reception confirmation code is read on the copyright protection software 51 side, one digit of the next password is recorded in the file Fβ from the copyright protection software 51 side.

  On the other hand, another aspect of FIG. 24 is shown in FIG. When it is determined that the user is the registrant in step 61 in FIG. 5, the activation execution file is operated in step 360, and the function-restricted software 1 is automatically activated. In step 362, it is determined whether or not a restriction release key for the software 1 with function restriction exists in the file FN. If it exists, in step 361, the copyright protection software 51 automatically inputs the password in the password field on the password input screen of the function-limited software 1. Alternatively, a password field for inputting a password may be designated by a mouse operation or the like, and then the password may be automatically input.

  On the other hand, if there is no restriction release key in step 362, the process jumps to step 57 in FIG. 5 in step 366, and it is determined again whether or not the user is the registrant. After the password is entered in step 361, the confirmation button is automatically operated in step 363, and in step 364, it is determined whether or not the password matches the password previously set in the software with function restriction 1. When they coincide with each other, the restriction is released at step 365 and the software 9 without function restriction is obtained. If not, the function restriction is continued in step 367.

  Also, the registration application on another personal computer in step 95 of FIG. 6 is processed by making an inquiry on the display screen of the copyright protection software 51. Executing the software 9 without function restriction at step 111 in FIG. 7 means executing the software 1 with function restriction.

  Similar to step 53 in FIG. 5, after the activation icon 43a is selected, an execution button (not shown) of the button unit 45 is clicked. In step 121, the restriction is released as shown in FIG. In step 115, the restriction release key for the function restricted software 1 of the file FN is deleted. The movement request button 31 in FIG. 8, the movement acceptance button 33 in FIG. 9, and the personal computer that has been accepted for movement in step 217 are also provided in the button unit 45.

  Step 201 in FIG. 8 is to select the execution execution file for the function-limited software 1 from the tree display unit 41 and then click the icon creation button (not shown) in the button unit 45 on the personal computer scheduled to be moved. Thus, the activation icon 43a of the copyright protection software 51 (for software 1 with function restriction) is created. Then, the activation icon 43a is selected.

  The move destination button in step 231 of FIG. 11 selects the move destination personal computer displayed on the button unit 45 in a state where the activation icon 43a is selected. The function restriction in step 237 is to delete the restriction release key for the function restricted software 1 in the file FN after the destination personal computer is selected.

  The personal computer button 35 shown in FIGS. 12 and 14 is also provided in the button unit 45. In step 251, the activation icon 43a is activated. The process of step 275 is the same as the process of step 63 of FIG. 5 described above.

  Executing the software 9 without function restriction at step 111 in FIG. 16 means executing the software 1 with function restriction. In step 121, the restriction is released as shown in FIG. In step 115, the restriction release key for the function restricted software 1 of the file FN is deleted.

  The execution of the software 9 with no function restriction in step 111 can be performed by double-clicking from the start menu, startup, desktop, etc., so that each software can be used without being aware of the copyright protection software 51 at the stage of use. Is possible.

  A move button 39 is also provided in the button unit 45 for each group in step 321 of FIG. The switch section of the selectable personal computer PC is also displayed on the button section 45. In step 325, one personal computer that is the movement destination is selected. As the start icon 43a, those usable in the personal computer are displayed in different colors. In step 331, the restriction release key for the function restricted software 1 moved from the personal computer is deleted.

  Next, it moves to the personal computer PCX of the movement destination, and clicks the movement button 39 for each group from the button part 45 of the copyright protection software 51 (step 341 in FIG. 21). In step 253, the use PC button 35 of the button unit 45 is clicked. In step 255, the data storage location is selected. In the case of a flexible disk, a flexible disk is required. In step 257, the data stored in step 329 is read from a flexible disk or the like. A group batch movement code G is detected from the data read in step 343.

  When the group collective movement code G is detected, the processing after step 259 shown in FIG. Then, for each function-limited software 1, in step 275, instead of releasing the restriction, if all the determination results in steps 259 to 269 are YES, the restriction release key is set together with the group batch movement code G of the file FX. Records for each function-limited software 1.

  The above processing is performed at once for all the function-restricted software 1 that has been moved in a state where each function-restricted software 1 is not executed. Thereafter, the function restriction is released according to FIG.

  Further, when uninstalling software is provided as an execution file or the like in the function-limited software 1, the execution file or the like is selected, and then an uninstall button (not shown) of the button unit 45 is clicked.

At this time, the time T _UN when the execution file is activated and the uninstall information UN code that is the fact of execution are recorded in the file FN. If the uninstall software is not provided as an execution file or the like, it is determined whether or not the uninstall has been performed based on whether or not there is a fact that it has been installed after the latest movement history data of the file FN.

  These points are the same in the second embodiment of the present invention, and the function-restricted software 1 is executed in step 402 in FIG. 22 after the start icon 43a is selected and then the execution button of the button unit 45. Click (not shown). The use inquiry of the personal computer is also processed by making an inquiry on the display screen of the copyright protection software 51.

  In step 411, first, a restriction release key for the function restricted software 1 is assigned to the file FN, and the restriction is released as shown in FIG. In step 415, the restriction release key for the function-limited software 1 is not given to the file FN.

  As described above, by using the copyright protection software 51, it is possible to easily manage even the software 1 with function restriction created independently of the copyright protection software 51. Even if the software 1 with function restriction is created in any language, copyright protection is possible. Since the copyright protection software 51 and the function-restricted software 1 are independent of each other, the mutual responsibility is also clear. Even if the copyright protection software 51 exists, the performance, processing speed, etc. of the function-limited software 1 do not change at all.

  In addition, a single piece of copyright protection software 51 can manage a plurality of software 1 with function restrictions. The existing function-limited software 1 can be applied only by a simple modification of changing a password processing method (for example, reading a password from a file designated in advance). Further, if the copyright protection software 51 automatically inputs the password in the password field, no correction is necessary. Therefore, it contributes effectively to shareware software distributed on the Internet and the like.

  Also, an independent registration software part 3 and identification software part 5 (copyright protection software 51) are prepared in advance, and this registration software part 3 is provided for each function-limited software 1 etc. that is shareware software. In addition, the identification software portion 5 (copyright protection software 51) may be set together and distributed over the Internet or the like. In this case, the function-restricted software 1 and the copyright protection software 51 are associated in advance as described above. Then, at the time of decompression after downloading, etc., the activation icon 43a of the copyright protection software 51 (for function-limited software 1) is registered in the start menu, startup, and desktop. However, the registration location may be selected by option setting.

  By clicking on the start icon 43a based on the association between the start icon 43a, the copyright protection software 51, and the start execution file of the function-restricted software 1, the copyright such as whether or not it is used on a registered personal computer. After the determination by the protection software 51 is made, it is possible to perform processing in order, such as executing the activation execution file of the software 1 with function restriction. Registration application and transfer processing can also be performed using the registration software part 3. Of course, it is possible to execute the activation execution file of the software 1 with function restriction as before, but in this case, for example, a password is not given and the function restriction is not removed.

  When the copyright protection software 51 is resident in a resident task, the copyright protection software 51 can be activated by activating an icon in the resident task whenever necessary. Even when the copyright protection software 51 is not resident, the copyright protection software 51 can be activated by directly selecting and executing the execution file of the copyright protection software 51 from the explorer screen or the like. The copyright protection software 51 may be activated by right-clicking on the activation icon 43a to display a selection menu and selecting activation of the copyright protection software 51 from the selection menu. An activation icon of the copyright protection software 51 may be created. When the copyright protection software 51 is activated, a screen is displayed that enables registration application, transfer processing, and the like. The movement process part can be made independent of the registration application part, the identification software part, and the like. You may make it make the starting icon for a movement process independent.

Even in the case of set distribution in this way, it can be applied to the existing software 1 with function restriction only by a simple modification of changing a password processing method (for example, reading a password from a file specified in advance). The function-restricted software 1 can be used on a registered personal computer.
Also, an independent registration software part 3 and identification software part 5 (copyright protection software 51) are prepared in advance, and for each shareware software, etc., this registration software part 3 and identification software part 5 etc. The copyright protection software 51) may be incorporated and distributed on the Internet. However, since the registration software part 3 is irrelevant to the function processing, it can be left unincorporated.

  For this incorporation, when the shareware software or the like reaches a predetermined program step, a program such as identification processing of the copyright protection software 51 may be executed. Accordingly, the copyright protection software 51 program itself (identification software portion 5 or the like) may be incorporated in each shareware software or the like, or the copyright protection software may be included in a part of each shareware software or the like. A function for operating 51 (identification software portion 5 or the like) may be incorporated. When the copyright protection software 51 program itself (identification software portion 5 or the like) is incorporated in each shareware software or the like, it is possible to eliminate data exchange or the like via the file Fβ or the like. Therefore, the processing of step 370 and step 359 in FIG. 24 may be omitted.

  When a function for operating the copyright protection software 51 (identification software part 5 or the like) is incorporated in a part of the program, the identification software part 5 functions according to the operation instruction of the copyright protection software 51, and the same as described above. After processing, the copyright protection software 51 creates a file Fβ and records a password. On the other hand, in shareware software or the like, in a program step following the operation of the copyright protection software 51, the password recorded in the file Fβ is read to determine whether the passwords match. Even in this case, it can be applied to the existing software 1 with function restriction only by simple correction.

  The copyright protection software 51 may be distributed together with the function-restricted software 1 on a recording medium such as a CD-ROM, in addition to being distributed as a set with shareware software or the like. Further, only the software 1 with function restriction is stored in a CD-ROM or the like, and after the software 1 with function restriction is installed in the user's personal computer, the corresponding copyright protection software 51 is downloaded from a predetermined site. May be. Even in this case, since the directory in which the function-restricted software 1 is installed can be found by referring to the file F1, the association between the copyright protection software 51 and the function-restricted software 1 is maintained. Therefore, the copyright protection software 51 and the function-restricted software 1 can be installed in different directories. The directory may be confirmed in the registry.

The usable personal computer can be moved sequentially. If it is moved, the source PC becomes unusable. Therefore, it is possible to cope with movement within the office and movement between the home and the company. Moving work is also easy. You can easily move to a new computer when you purchase a new one. In this case, the right to use the software on the previous PC is transferred to the PC after purchase. It is also possible to move the function restriction release in units of groups or PCs.
It should be noted that part of the registration application process by the registration software part 3, the transfer process of the usage right, and the identification process by the identification software part 5 can be processed not by the personal computer side but by the Internet server side.

Even when the OS is reinstalled or the flexible disk is damaged, it can be easily dealt with. There is no problem that the copyright manager is forced to overuse a plurality of software licenses due to the purchase of a new personal computer or the re-installation of the OS, which may occur when the personal computer is limited.
Next, a description will be given of a case in which a plurality of function-limited software 1 is started in sequence when the personal computer is started. In the above description, the activation icon 43a of each copyright protection software 51 (for function-restricted software 1) is registered as a startup, and the activation process is performed. However, it is preferable to avoid that many software programs are activated at the same time.

  For this reason, as shown in FIG. 30, the function-limited software 1 that is desired to be activated when the personal computer is activated can be set in the activation order column 111 in a desired time sequence in the order of activation. At this time, the start icon 43a of each copyright protection software 51 (for function-limited software 1) existing in the start icon display section 43 can be moved to the start order column 111 by drag and drop. The order in the activation order column 111 can also be changed by drag and drop movement. And when starting, it starts so that there may be no duplication according to each order of order. For this reason, the load factor of the memory is monitored so that the next function-limited software 1 is not started until the start of one function-limited software 1 is completed. And when this load factor becomes below a setting value, the following software 1 with a function restriction | limiting is started. However, a timer may be set between the software 1 with function restriction, and the user may arbitrarily adjust the time of this timer.

A startup icon of the copyright protection software 51 is set for startup under the Windows (R) directory of the personal computer. As a result, the copyright protection software 51 is activated at the same time as activation of the personal computer, and then the software 1 with function restriction is activated in accordance with the specified order. In this case, after the judgment by the copyright protection software 51, such as whether or not to use it on a registered personal computer, is performed, the orderly processing such as executing the activation execution file of the software 1 with function restriction is performed. Can be done.
It should be noted that normal software that is not judged by the copyright protection software 51 can be set in the activation order column 111. In this case, an execution file for starting arbitrary software is selected from the tree display section 41, and then an icon creation button (not shown) of the button section 45 is clicked to start the software startup icon 113a. The icon display unit 43 is prepared. The start icon 113a is preferably displayed in a different color from the start icon 43a. This activation icon 113a can be inserted by dragging and dropping at a desired position in the activation order column 111.

In addition, an activation icon of the copyright protection software 51 may be registered in a start menu, a desktop, or the like to function as a program launcher.
Further, the operation procedure is sequentially recorded for the mouse operation and the keyboard operation, the reproducible software is registered in the middle of the activation order column 111, and the operation procedure is reproduced according to the pre-registered operation procedure. Can be automated after startup.
In this activation order column 111, it is also possible to set a software in which the copyright protection software 51 and the function-restricted software 1 are set. Even in this case, the activation icon 43a of the copyright protection software 51 (for function-limited software 1) may be set in a desired order.

Next, a fourth embodiment of the present invention will be described.
In the fourth embodiment of the present invention, as in the third embodiment of the present invention, the registration software portion 3 and the identification software 5 portion of the first embodiment and the second embodiment of the present invention are made independent software. This function is applied to video distribution software such as moving images and still images, music distribution software, compact discs containing video, music, and the like (hereinafter referred to as music distribution software).

  The music distribution software or the like is, for example, a trial restricted file 61 so that the intro part or the characteristic part can be seen and heard for a short period of time or only for a predetermined period after installation. In this case, only the intro part or characteristic part may be filed and the remaining part may be omitted, or the intro part or characteristic data part may be left and other data parts may be encrypted (or compressed). Etc.). However, the entire music distribution software or the like may be encrypted (or compressed) with respect to the entire trial restricted file 61 so that trial use is restricted.

  In the case of a still image or the like, the size is limited or the number of pixels and colors are limited. The limitation is, for example, that a mosaic is obtained by adding or subtracting a specific digital signal over a range where the original image is divided into a plurality of pixels in the vertical and horizontal directions or the entire range of the original image with respect to the digital information value of the color of each pixel The image quality is deteriorated in the wind or overall. An example of the display screen of the copyright protection software 71 according to the fourth embodiment of the present invention is shown in FIG. Note that the same components as those in FIG. 23 are denoted by the same reference numerals, and description thereof is omitted.

  In FIG. 26, the left half of the screen is a tree display unit 41 in which drives, directories, and files are displayed in a tree structure in a hierarchical structure, such as an explorer screen of Microsoft (R). However, the file name is extracted from the file 61 with trial restriction instead of a simple file name, and is displayed with a name that is easy to understand, such as a song name.

  Alternatively, only music distribution software or the like may be displayed as a list. The right half of the screen is a player 65 in the case of music distribution software or moving images, for example. The player 65 may be originally incorporated in the copyright protection software 71. However, for example, the necessary player 65 may be selected from the start menu by clicking the start 63 on the task bar.

  Note that the player 65 may be activated independently of the copyright protection software 71 when performing a performance or the like. Also, the copyright protection software 71 may be independent of the copyright protection software 51, but can also be made together by selecting a mode. In this case, for example, a mode selection button for selecting each mode such as application software, game software, music, moving image, still image, and the like is provided on the button unit 45.

  If the information stored on a compact disc is large, all the data is not filed and saved on the hard disk by installation, but a song name and a password to remove trial restrictions are required. It is only necessary to save the minimum file. The trial restricted file 61 is supplied by a download or a recording medium such as a CD-ROM. If you would like to continue to see and hear through trial use, first apply for registration as follows.

  In FIG. 3, the file 61 with trial restriction is selected from the tree display portion 41, and then the registration application button 11 in the button portion 45 is clicked. The installation information in step 3 is, for example, the time when the registration application button is clicked or the time when the trial restriction file 61 is selected. If it is desired to apply for registration of a plurality of trial-limited files 61 due to the presence of a plurality of pieces of music or the like to be listened to, the processes in steps 1 to 5 are repeated. Then, a selection completion button (not shown) of the button unit 45 is clicked. Thereafter, the processing after step 7 is performed.

  It is assumed that a password or the like is added to the information FB of the restriction release file 8 in FIG. The trial restricted file 61 is compared with a password or the like each time it is activated, and it is determined whether or not to release the restriction. If a part or all of the file of the trial restricted file 61 is encrypted (or compressed) in advance, it must be a key having a certain relationship with the key used for the encryption. It is not decrypted (or decompressed). A key having a certain relationship is included in the information FB as a password or the like. For encryption, for example, a public key method or a common key method can be adopted.

  The password is a secret key when the public key method is used for encryption and the trial restricted file 61 is encrypted with the public key, while the common key method is adopted and the trial restricted file 61 is shared. When encrypted with a key, it is a common key. The relationship between the public key and the secret key is a key that is generated at the same time and has a certain close relationship, and data encrypted with the public key can be decrypted only by the secret key. Therefore, when a part of the file or the like is provided in advance by being encrypted with a public key in a recording medium such as a download site or a CD-ROM, the secret key is included in the information FB as a password or the like. On the other hand, when encrypted with the common key, the common key is included in the information FB as a password or the like. It is desirable that the public key (secret key), the common key, and the like are different for each trial restricted file 61.

  The process of executing the function-restricted software 1 in step 53 of the flowchart of FIG. 5 is assumed not to be in the form of an executable file when the trial-restricted file 61 is a data file such as music distribution software. The For this reason, it does not fit in the form of execution.

  Therefore, the process of executing the function-restricted software 1 in step 53 starts the copyright protection software 71. In step 55, if the file FN exists, it is determined whether or not a restriction release key exists in the file 61 with trial restriction of the file FN (each piece of music, etc.). If there are a plurality of files FN, it is determined whether or not there is a restriction release key in the trial restricted files 61 (each music, etc.) of all the files FN.

  Also, if there are a plurality of trial-limited files 61 (each song etc.) in one file FN, it is judged whether or not there is a restriction release key over all the trial-limited files 61 (each song etc.). Is done. If there is no restriction release key, the process proceeds to step 57.

  In step 59, when the contents of the file F1 and the contents of the information FB of the restriction release file 8 are compared, information is recorded in advance in the header part of the trial restricted file 61, or information is included in a song or image by digital watermark technology. Is embedded in advance. Then, it is desirable to read the embedded information and compare the contents of the file F1 and the information FB of the restriction release file 8 with the read information to determine whether they match. Even if the restriction release file 8 is omitted and the content of the information FB is downloaded from the copyright manager side in the header part of the trial-restricted file 61 or in the form of a digitally watermarked song, image, or program. Good. In this case, the embedded information is read out and compared with the contents of the file F1.

  The information is, for example, a song name or a file name of the trial restricted file 61 (each song etc.). However, the author information and the contents of function restrictions may be added. According to the author information etc., the attribution of the copyright becomes clear. If the content of the function restriction is embedded, the watermark information can be read and the function restriction corresponding to the content can be applied at the time of reproduction. Even if the trial restricted file 61 (each song, etc.) is transferred to another playback device or the like that is capable of reading watermark information and restricting functions, the data specifications should be unified. For example, it is possible to perform playback processing according to the function restriction.

  If the trial-restricted file 61 for which registration has been applied in FIG. 3 is stored, and there is no restriction release key in the header part of the trial-restricted file 61 or watermark information embedded by the digital watermark technology, etc. You may make it progress to 57. If it is determined in step 61 that the user is the registrant, the process proceeds to step 63, and a restriction release key is set for the trial restricted file 61 (each song, etc.) of the file FN. In step 67, the trial restricted file 61 in which the restriction release key is set is distinguished by color-coded display or the like.

  Also, the registration application on another personal computer in step 95 of FIG. 6 is processed by making an inquiry on the display screen of the copyright protection software 51. The process of executing the software 9 without function restriction in step 111 in FIG. 7 is to start the copyright protection software 71. In step 113, it is determined whether or not the corresponding file FN exists for all the trial restricted files 61. In step 117, it is determined whether or not an UP code exists in the contents of the file FN.

  In step 121, instead of the processing in step 121, the processing in FIGS. 27 and 28 is performed. In FIG. 27, the file 61 with trial restriction is selected from the tree display unit 41 in step 501. At this time, the trial restricted file 61 to which the restriction release key is set in step 67 is distinguished by color-coded display or the like and can be selected from the trial restricted file 61 so that it can be easily selected.

  After selection, a selection button (not shown) of the button unit 45 is clicked in step 503. If it is desired to select a plurality of songs, step 501 to step 505 are repeated. When the selection is completed in step 505, the process proceeds to the next step 507, and a selection completion button (not shown) of the button unit 45 is clicked.

  At this time, reproduction is performed in the subsequent processing according to the selected order. However, a process of changing the order selected between step 505 and step 507 may be inserted.

  When the selection completion button is clicked, it is determined in step 509 whether, for example, the restriction release key is set for the first selected song. If the restriction release key is set, in step 511, the password assigned to the song is administered to the file Fβ.

  If the restriction release key is not set, the password is not administered to the file Fβ in step 513. In step 515, it is determined whether or not processing has been performed for all the selected restricted trial files 61, and if all the processing is completed, the process stops in step 517.

  Next, a method for reproducing the selected trial restricted file 61 will be described.

  In FIG. 28, the playback button of the player 65 is clicked at step 531. In step 533, the player 65 first reads data from the trial restricted file 61 according to the selected order. This data includes a password in addition to the song data. This password is incorporated in, for example, a header part or watermark information. The password is preferably encrypted. Subsequently, in step 535, the data of the file Fβ is read.

  In step 537, the data read from the trial restricted file 61 is compared with the data read from the file Fβ, and if the password corresponding to the trial restricted file 61 (for example, a song) matches, the trial restriction is given in step 539. Is released.

  In step 541, the password is immediately deleted from the file Fβ to prevent leakage. However, this deletion may be performed on the copyright protection software 71 side when the copyright protection software 71 is terminated. On the other hand, if the passwords do not match, the trial restriction is continued in step 543.

  If part or all of the trial restricted file 61 is encrypted (or compressed), the trial restricted file 61 is decrypted (or decompressed) using the password read from the file Fβ as a key. I do. For example, when the trial restricted file 61 is encrypted with a public key, it can be decrypted with a corresponding private key prepared as a password or the like (or when encrypted with a common key) The common key prepared as a password can be decrypted). Therefore, in step 63 of FIG. 5, the secret key is extracted from the information FB of the restriction release file 8 and stored in the file F1. In FIG. 28, step 533 is omitted, and the password recorded in the file Fβ in step 535 is a secret key. This secret key is applied to the file Fβ in step 511 of FIG. In step 537 of FIG. 28, instead of determining whether the passwords match, the trial restricted file 61 is decrypted using the secret key as a key. The decrypted data is expanded on a memory, for example. The player 65 performs reproduction based on the data of the trial restricted file 61 that has been decrypted.

It is more desirable that the public key (secret key), the common key, and the like are different for each trial restricted file 61 to be downloaded or for each CD-ROM. At this time, for example, the following processing is performed.
First, a serial number is given to each unit such as each trial restricted file 61 to be downloaded. The assigned serial number is stored in the database of the copyright management center. The serial number is stored in an attached file attached to each trial restricted file 61. This attached file is downloaded to the user's personal computer when the trial restricted file 61 is downloaded. When a download request is made by the user (or when a CD-ROM or the like is created), a key is generated. For example, when a public key method is adopted, a public key and a secret key are generated. Based on the public key, a part of the trial restricted file 61 or the whole trial restricted file 61 is first encrypted and downloaded to the user (or recorded on a CD-ROM) in this encrypted state. The The private key is stored along with the serial number in the copyright management center database.

  When the trial restricted file 61 is installed in the user personal computer, the serial number is first saved in the file F1 from the attached file together with the file information and the like. Then, when the user likes by trial listening or the like and wants to register or purchase the trial restricted file 61 officially, the user applies for registration through the copyright protection software 71. When applying for registration, the file F1 is transmitted to the copyright management center in step 19 of FIG. The copyright management center extracts the corresponding secret key from the database based on the serial number extracted from the received file F1. This secret key and serial number are included in the information FB of the restriction release file 8. If it is determined in step 61 of FIG. 5 that the personal computer is a personal computer at the time of registration application, a secret key is extracted from the information FB and stored for the serial number of the file F1. In FIG. 28, the password recorded in the file Fβ in step 535 is a secret key. In step 537, instead of determining whether the passwords match, the trial restricted file 61 is decrypted using the secret key as a key.

  Next, in addition to the trial restricted file 61 to be evaluated, a trial unlimited file 62 that is not trial limited is prepared, and the user evaluates the trial restricted file 61 and officially registers and purchases it. In the case where the user wants to use the file, a case where the trial unlimited file 62 is provided in the form of a download or a CD-ROM will be described. When the trial-restricted file 61 is installed in the user personal computer, the file name (song name, etc.), the product ID that is the product number of this file, and the like are stored in the file F1. When the user wants to obtain the unrestricted trial file 62, the user applies for registration through the copyright protection software 71. When applying for registration, the file F1 is transmitted to the copyright management center in step 19 of FIG. The copyright management center extracts the user-desired trial unlimited file 62 from the product ID extracted from the received file F1. Thereafter, a part or the whole of the trial use-restricted file 62 is encrypted. At the time of encryption, it is desirable to generate an encryption key based on personal computer specific information, OS information, system information, etc. extracted from the file F1. A key generation theoretical value a indicating the theoretical value for generating the encryption key may be defined. The key generation theoretical value a indicates a logical procedure for generating an encryption key as will be described in detail later.

  The key generation theoretical value a is stored in the database of the copyright management center and is included in the information FB of the restriction release file 8. The encrypted unlimited trial file 62 and the restriction release file 8 are sent to the user's personal computer via the Internet or the like. If it is determined in step 61 of FIG. 5 that the personal computer is a personal computer at the time of registration application, the key generation theoretical value a is extracted from the information FB and stored for the file information of the file F1. In FIG. 27, when the password is administered to the file Fβ in step 511, personal computer specific information, OS information, system information, etc. are extracted from the file F1, and decrypted based on the key generation theoretical value a from these information. After the key is generated (a method for generating a decryption key based on the key generation theoretical value a will be described later), this decryption key is administered as a password. In step 537, instead of determining whether the passwords match, the trial unlimited file 62 is decrypted using the decryption key as a key. The decrypted unrestricted trial file 62 is expanded on the memory and reproduced by the player 65. However, the key generation theoretical value a is not included in the information FB of the restriction release file 8, but the generated key (a secret key when the trial-use unrestricted file 62 is encrypted with a public key, In the case of encryption with a key, a common key) may be included. The generated key may not be generated based on personal computer specific information, OS information, system information, or the like.

  In step 537, it is determined whether or not the passwords match. Instead of the password, the information FB of the restriction release file 8 in FIG. 4 includes a plurality of initial digital signal data such as music pieces. When (for example, sampling data) is added as data, and there is a restriction release key, this data is administered to the file Fβ. Then, the data read from the trial restricted file 61 may be compared with the data read from the file Fβ.

  In addition, instead of comparing the data read from the trial restricted file 61 with the data read from the file Fβ, if there is a restriction release key in the header part or watermark information of the trial restricted file 61, for example, It is also possible to unconditionally play the file 61 with trial restriction on the player 65 side. At this time, for example, in step 511, a predetermined key for the file 61 with trial restriction is administered to the file Fβ.

  On the player 65 side, if this predetermined key exists in the file Fβ, the restriction of the trial restricted file 61 is canceled in step 539, and the performance or the like is continued. However, when the player 65 and the copyright protection software 71 are integrated, the process of exchanging a predetermined key via such a file Fβ is eliminated, so that safety such as further simplification and prevention of secret leakage is achieved. Can be achieved.

  In FIG. 7, for the trial restricted file 61 in which the file FN does not exist in step 113, the process proceeds to step 115, the processing of FIGS. 27 and 28 is not performed, and the trial restriction is not released. If there is a mismatch between step 119 and step 123, the restriction release key is deleted from the trial restriction file 61 of the file FN (each piece of music, etc.). The movement request button 31 in FIG. 8, the movement acceptance button 33 in FIG. 9, and the personal computer that has been accepted for movement in step 217 are also provided in the button unit 45.

  The move destination button in step 231 in FIG. 11 switches the move destination personal computer displayed on the button unit 45 in a state where the trial restricted file 61 is selected. Further, the function restriction in step 237 is to delete the restriction release key for the file 61 for trial use restriction (each piece of music, etc.) of the file FN after the destination personal computer is selected.

  The personal computer button 35 shown in FIGS. 12 and 14 is also provided in the button unit 45. The activation of the software with function restriction in step 251 is the activation of the copyright protection software 71. In step 275, a restriction release key is set in the file FN for each piece of music (file 61 with trial restriction). In step 279, the restricted trial file 61 with the restriction release key set is distinguished by color-coded display or the like.

  The function restriction in step 260 is that a restriction release key for the file 61 with trial restriction is not given to the file FN. The process of executing the software 9 with no function restriction in step 111 of FIG. 16 starts the copyright protection software 71.

  In step 121, instead of the processing in step 121, the processing in FIGS. 27 and 28 is performed. In Step 115, the restriction release key for the file 61 with trial restriction of the file FN is deleted.

  A move button 39 is also provided in the button unit 45 for each group in step 321 of FIG. The switch section of the selectable personal computer PC is also displayed on the button section 45. In step 325, one personal computer that is the movement destination is selected. Files 61 that can be used on the personal computer are displayed in different colors because of the presence of the restriction release key of the file FN.

  In the case where it is not appropriate to manage with a password as in a still image, a predetermined key may be administered in step 511 in FIG. The predetermined key is preferably a key common to all still images, unlike a password that is different for each music piece.

  In step 531 of FIG. 28, image display software is activated. In step 533, the file name for distinguishing still images is read. In step 535, a predetermined key is read from the file Fβ, and if the predetermined key exists in step 537, the function restriction is released in step 539.

  These points are the same in the second embodiment of the present invention, and the process of executing the function-restricted software 1 in step 402 in FIG. 22 starts the copyright protection software 71. The use inquiry of the personal computer is also processed by making an inquiry on the display screen of the copyright protection software 71.

  In step 411, a restriction release key is set in the file F1 for each piece of music. In step 413, the file 61 with the trial restriction set with the restriction release key is distinguished by color-coded display or the like. In step 415, the restriction release key for the file 61 with trial restriction is not given to the file FN.

  The player 65 can be played back by performing the processing shown in FIG. 28, so that the player 65 is started independently of the copyright protection software 71, and the trial restricted file 61 is selected on the Explorer screen of Microsoft (R), or the player 65 Reproduction processing is also possible in accordance with a procedure such as file-opening at 65.

Although the copyright protection software 71 has been described as being independent of the player 65 or the like, the function of the copyright protection software 71 may be included in the player 65 or the like. Further, the player 65 and the like may be configured by hardware, and copyright protection software 71 may be incorporated therein. In this case, the buttons of the button unit 45 may be hardware buttons.
In the processing from step 507 to step 517 in FIG. 27, the password administration process is not performed for all the selected trial-restricted files 61, but the password is administered to the file Fβ for each song sequentially. Subsequently, the reproduction process may be performed in step 531. At this time, it is desirable to administer a fluctuation value such as time information in addition to the password to the file Fβ.
Further, each time a password is administered, it may be compared with personal computer-specific information or OS information as shown in step 119 of FIG.

In the present invention, the hardware is described as a personal computer. However, the present invention is not limited to a personal computer, and can be widely applied to any information processing device (game machine, mobile phone, television, etc.) that handles copyrighted works. The flexible disk may be another movable recording medium (such as a memory or a card).
Further, for example, in the header portion or watermark information of the trial restricted file 61, information necessary for movement information such as the contents of the file F1 and a password is recorded, and the trial restricted file 61 is moved between information processing devices. You may make it make it. In this case, the copyright protection software 71 records this information in the file 61 with a trial restriction or reads it from the file 61 with a trial restriction when moving.

  Further, in the restriction release file 8 of each embodiment, in addition to this information FB, movement between information processing devices (may be between information processing devices that are different from each other) is used for the software 1 with function restriction and trial use. You may make it provide the movement restriction | limiting code | cord | chord which makes restriction or impossible for every restricted file 61. FIG. In this case, it is possible to move only between a designated number of times (for example, once), a designated period, or between designated information processing devices, or it is possible to use the function-limited software 1 or the like only on an information processing device for which registration is applied. .

  Further, for example, the downloaded software 1 with function restriction and the file 61 with trial restriction can be used only for two weeks. If the trial restricted file 61 is an electronic book, an electronic magazine, an electronic comic, or the like, it is possible to realize an electronic library that can lend an electronic book or the like on the Internet. However, it is not limited to lending and may be charged.

  Download the copyright protection software 71 and the trial restricted file 61 from the electronic library site. As a result of trial listening to the trial restricted file 61 (for example, a book), if it is desired to request the rental of this book, the application for registration etc. using the copyright protection software 71 is the same as described above, so it is omitted. . From the electronic library side, a password or the like may be transmitted to the information FB of the restriction release file 8, and the trial restricted file 61 may have a minimum file capacity (thus, several pages in the case of an electronic book etc. If the application for registration is made, the remaining official version files may be downloaded.

In this electronic library, for example, after two weeks have passed since lending, the copyright protection software 71 deletes the restriction release key for the file 61 with the trial restriction of the file FN. However, when two weeks have passed, the copyright protection software 71 may warn on the screen so that the restriction release key is automatically returned to the electronic library and guide the operation method at that time.
This warning message describes, for example, “The return time of the lent electronic book has passed. Please process the return. After connecting to the Internet, press the designated return button in the button section 45.” When the user presses the return button after connecting to the Internet, the URL of the electronic library site preset in the browser is entered. Thereafter, the copyright protection software 71 deletes the restriction release key for the file FN with the trial restriction of the file FN, and automatically transmits this restriction release key to the electronic library server. However, in this case, it is desirable to delete the trial restricted file 61 itself or automatically transmit the trial restricted file 61 deleted from the user's personal computer to the electronic library server.

  As a result, browsing of the trial restricted file 61 is restricted or cannot be browsed. On the electronic library side, the received restriction release key can confirm that the trial restricted file 61 has been returned and can be utilized for management. By limiting the lending period to, for example, two weeks, the interests of the copyright holder can be protected. In the case where dedicated reproduction software for reproducing the trial restricted file 61 is provided, the reproduction software can be configured to exchange predetermined keys via the file Fβ. In addition, a case in which general reproduction software is applied instead of such reproduction software may be considered. However, even in this case, the lending period is specified in the header portion and watermark information of the trial restricted file 61 together with the author information. Then, the copyright protection software 71 extracts this information and compares it with the file FN or the like, so that it is possible to deal with unauthorized copying of the trial restricted file 61. The user can use the trial restricted file 61 in another information processing facility by moving the file. Therefore, it is stored in the mobile information processing terminal and can be carried in the vehicle.

  On the electronic library side, it is determined whether or not this transmission has been performed accurately and necessary data has been transmitted. When it is determined that the transmission is accurate, a specific reception confirmation signal is transmitted to the copyright protection software 71 from the server on the electronic library side. When the reception confirmation signal is received, the copyright protection software 71 prevents the warning message from being displayed. Note that the copyright protection software 71 issues a warning if the copyright reception software 71 does not confirm this specific reception confirmation signal for a long period of time. Thereafter, registration application for lending other books is prohibited.

Next, a fifth embodiment of the present invention will be described.
In the fifth embodiment of the present invention, when connecting to the Internet or the like, it is impossible to connect from a device other than the information processing device for which registration has been applied or the information processing device to which the use permission has been transferred. When connecting to the Internet or the like, if the user ID and password set for each provider match, it can be accessed from any information processing device, for example, a plurality of devices. For this reason, it is impossible to connect from a device other than the information processing device that has applied for registration or transfer.

  An example of the display screen of the copyright protection software 81 is the same as the display screen of the copyright protection software 51 of the third embodiment of the present invention shown in FIG. Provider registration is selected from a mode selection switch (not shown) of the copyright protection software 81. The provider name can be selected from the copyright protection software 81, for example. At this time, it is desirable that the URL of this provider is also selected at the same time. In addition, it is desirable to display provider names that can be selected by selecting a region such as a residence.

  An execution file (or icon) for starting up an Internet connection is selected from the tree display unit 41, and then an icon creation button (not shown) in the button unit 45 is clicked. At this time, an activation icon 83a for Internet connection is created in the activation icon display section 43. As a result, the startup icon 83a, the copyright protection software 81, and the startup executable file for Internet connection are associated with each other.

  Therefore, by clicking on the activation icon 83a, the determination by the copyright protection software 81, such as whether or not it is used on a registered personal computer, is made, and then the execution file for starting the Internet connection is executed. You can follow the process. And the file F1 of FIG. 2 is produced. The software name is the provider name, and the execution date / time / minute / second is, for example, the click time of the icon creation button. Directory information is not required.

  In step 1 of FIG. 3, the registration application button 11 is clicked. If there is no problem with the items described in the e-mail or the like in step 15 or step 29, the confirmation button is clicked in step 17 or step 31.

  The restriction release file 8 includes the user I.D. D. And a password. In step 53 in FIG. 5, after the activation icon 83a is selected, an execution button (not shown) of the button unit 45 is clicked.

  In step 59, it is determined whether or not the content of the file F1 matches the content of the information FB of the restriction release file 8. As a result, if they match, the use permission code is written in the provider name of the file F1 in step 63. At this time, the user I.D. D. And the password are recorded in the file F1.

  When connecting to the Internet, it is determined whether or not a use permission code exists in the file F1 from the provider name and the user name. If it exists, after the processing of FIG. 7 is performed, the password is automatically input and transmitted on the dial-up connection screen, and the connection is completed. If there is no use permission code, the dial-up connection screen is not erased or activated, and connection to the Internet is not performed.

  For example, the password may be entered by clicking on a password entry field and then clicking a password administration key button (not shown) from the button unit 45. Alternatively, the password input field may be clicked, and then the password may be automatically administered. At this time, the password for the provider is extracted from the file F1, and is administered and transmitted to the password input field.

  Executing the function-unlimited software 9 in step 111 in FIG. 7 is the same as in step 53 in FIG. In step 121, it is determined whether or not a use permission code exists in the file F1 from the provider name and the user name when connecting to the Internet.

  If it exists, after the processing of FIG. 7 is performed, the password is automatically input and transmitted on the dial-up connection screen, and the connection is completed. If the use permission code does not exist, the process proceeds to step 115 where the dial-up connection screen is not erased or activated, and connection to the Internet is not performed. If there is a mismatch at step 119 or the like, the use permission code is deleted from the file F1.

  When the use of the Internet is moved between information processing devices, the processing from FIG. 8 is performed. Step 201 in FIG. 8 is to select the execution file (or icon) for starting the Internet connection from the tree display section 41 on the personal computer scheduled to be moved, and then click the icon creation button (not shown) in the button section 45. Thus, an activation icon 83a is produced. Then, this activation icon 83a is selected. In step 203, the movement application button is clicked from the button unit 45. In step 209, the activation icon 83a is selected on the source personal computer. In step 235 of FIG. 11, the provider name, user name, password, and the like are also saved.

Step 251 in FIG. 12 selects the activation icon 83a on the destination personal computer. In step 275, the same processing as in step 121 is performed.
Note that a movement restriction code may be further added to the restriction release file 8. According to the movement restriction code, it is possible to restrict the movement destination to only one place or not to allow movement.

  As described above, only the registrant can use it. It becomes impossible to access the Internet simultaneously from multiple information processing devices. You can easily transfer Internet usage rights even if you buy a new information processing device. The password stored in the file F1 is encrypted and can be decrypted and used only at the time of use, and the registrant is not informed of the document. Since the connection screen is deleted immediately after connecting to the Internet, it is not easily known and it is difficult to lend it to others.

Next, a sixth embodiment of the present invention will be described.
In the sixth embodiment of the present invention, copyright protection software is used for a WWW (World Wide Web) homepage that is permitted to enter with a password or the like, electronic payment, and the like.

  An example of the display screen of the copyright protection software 91 is the same as the display screen of the copyright protection software 51 of the third embodiment of the present invention shown in FIG. A password issuance is selected by a mode selection switch (not shown) of the copyright protection software 91. Connect to the Internet and open a home page where you want permission to issue a password.

  At this time, the file F1 is created by clicking the registration application button 11. In the file F1, as shown in FIG. 2, the homepage title is substituted for the software name, and the homepage URL is automatically obtained and recorded instead of the directory. Also, the date, time, minute and second when the registration application button 11 is clicked are recorded.

  A registration application is made according to FIG. 3, and the restriction release file 8 is transmitted. In the case of electronic payment, the card number, name, address, etc., which are credit card information, are transmitted only once at the time of registration application. However, this information transmission is preferably performed separately by fax or mail from the point of data leakage. The transmitted data is stored in a database on the server side. The restriction release file 8 includes the user I.D. D. A password is provided. Further, a movement restriction code may be added. Execution of step 53 in FIG. 5 is activation of the copyright protection software 91.

  If there is no restriction release key in step 57, a request screen for selecting a restriction release file is displayed. If it is confirmed in step 59 and step 61 that the user is the registrant, the process proceeds to step 63. In step 63, the homepage admission permission code is given to the homepage title of the file F1.

  Next, after reopening the homepage, a password administration key (not shown) is clicked from the button unit 45. In this case, first, the homepage title and the homepage URL are automatically extracted. Then, the contents of the file F1 are compared with the homepage title and homepage URL that are automatically extracted.

  Thereafter, it is determined whether a homepage admission permission code corresponding to the homepage exists. D. The password is extracted, and is administered and transmitted to the password input field. This eliminates the need to remember a different password for each homepage. Operation is extremely simple and can be done in a short time. Only the registrant can use it.

Note that when the homepage title is present in the contents of the file F1, the color of the password administration key may be changed to indicate that it can be clicked.
Further, it monitors whether or not the homepage title and homepage URL that are automatically extracted are present in the contents of the file F1. When the presence of the homepage admission code corresponding to this homepage is confirmed, the user I.D. D. Alternatively, a password may be extracted and administered and transmitted to a password entry field or the like. Furthermore, the transmitted user I.D. D. If the registered credit card information that matches on the server side is extracted from the database based on the password, electronic payment after the user purchases a product or the like by Internet shopping or the like becomes possible. User I. D. If the information at the time of registration application can be automatically communicated from the file F1 in addition to the password, the accuracy of the personal authentication is further improved. Note that all these pieces of information may be transmitted after being encrypted. Similarly, it can be applied to stock transactions and financial transactions.

In addition, since user authentication can be performed reliably, for example, a coupon can be given to a user once per person or a privilege limited to the user can be given to the user on the server via the Internet. For example, it is possible to challenge a lottery or the like only a predetermined number of times.
In addition, the user can use the user I.D. D. If the password is given in advance, the user I.D. D. You can also register your own password. In this case, the user first connects to the Internet and opens a home page for which an automatic password entry is desired. Next, a file F1 is created by clicking a registration button (not shown). If the file F1 has already been created, it is not overwritten. In the file F1, instead of the home page title and directory, the home page URL is automatically acquired and recorded. Then, the entered user I.D. D. The password is acquired by the copyright protection software 91 and stored in the file F1. However, user I.D. D. The password may be stored in the file F1 after the key is separately input on the registration screen by the copyright protection software 91.

Next, when the user visits this site again, after opening the home page, a password administration key (not shown) is clicked from the button unit 45. In this case, first, a home page title and a home page URL are automatically extracted from the home page. Then, the contents of the file F1 are compared with the homepage title and homepage URL that are automatically extracted.
If there is a match as a result of the comparison, the user I.D. D. The password is extracted from the file F1, and is administered and transmitted to the password input field or the like. This eliminates the need to remember a different password for each homepage. Operation is extremely simple and can be done in a short time.

Note that when the homepage title is present in the contents of the file F1, the color of the password administration key may be changed to indicate that it can be clicked.
In addition, the homepage title and the URL of the homepage are extracted every time the URL is changed. Then, it is monitored whether or not the homepage title and homepage URL automatically extracted are present in the contents of the file F1. When the presence is confirmed, the user I.D. D. Alternatively, a password may be extracted and administered and transmitted to a password entry field or the like.

  Also, the homepage title and homepage URL for which password registration application has been completed by the registration application button 11 or password registration has been performed by the registration button may be listed in the tree display section 41. Then, a home page title and a home page URL are selected from the tree display unit 41, and an activation icon 83a for Internet connection is activated from the activation icon display unit 43. As a result, the homepage is opened simultaneously with the Internet connection, and user I.D. D. And password can be administered automatically and promptly.

  In FIG. 7, the copyright protection software 91 is activated in step 111. If there is a mismatch at step 119 or the like, the homepage admission permission code is deleted at step 115. In step 121, processing after the password administration key is clicked from the button unit 45 becomes possible. Apply for password registration with the registration application button 11 or register the password with the registration button. D. Both passwords can be moved. In FIG. 8, a home page title and a home page URL are selected from the tree display unit 41 in step 201. In step 203, the movement application button is clicked from the button unit 45.

  In step 209 of FIG. 9, the copyright protection software 91 is activated. In step 237 of FIG. 11, the homepage admission permission code of the movement source personal computer is deleted. Step 251 in FIGS. 12 and 14 starts the copyright protection software 91 on the destination personal computer. As a result of updating the file F1 in step 273, the homepage title, the homepage admission permission code for each URL of the homepage, etc. are also updated. It is also possible to move all homepage titles, homepage URLs, passwords, and the like in units of groups in the processing after step 321 in FIG.

Next, a seventh embodiment of the present invention will be described.
The seventh embodiment of the present invention protects copyrights in units of broadcasting stations, such as digital broadcasting, instead of the software 1 with function limitations and the files 61 with trial limitations, and records, records, etc. from the broadcasting stations. It tries to protect the data acquired by.

  Viewers apply for registration for viewing on a broadcasting station basis. When applying for registration, the file F1 of FIG. 2 is created. However, OS information and directory information are not necessary unless they are sufficient to identify each information processing device. Instead of the installation information such as installation execution date and time, the execution date and time at the time of registration application are set as the execution date and time. In addition, as information for specifying each information processing device, information that records the use of a specific operation switch together with the execution date, time, minute, and second may be used. In addition, a code for specifying a broadcasting station is recorded instead of the software name.

  When the content of the file F1 matches the content of the information FB of the restriction release file 8 in step 59 of FIG. 5, it is determined in step 61 that the information processing device is the application for registration of the registrant himself. The restriction release file 8 may be obtained via the Internet or the like. In step 63, the program can be viewed. If the user wants to view the program on another information processing device, the program is performed according to the moving method described in FIG. In this case, the processing of step 201, step 209, step 251, and step 111 is activation of each information processing device. The processing in step 121 enables viewing of the program.

  Further, when recording each program, the program name, movement permission code, code for identifying the broadcast station, etc. received accompanying the program are additionally recorded in the file F1. As the movement permission code corresponding to the program, a code transmitted using a carrier band such as characters different from the carrier band of video may be used. This movement permission code is added to a program as a digital signal, and is a code that designates permission as to whether or not a work to be recorded can be moved between information processing devices.

  In FIG. 7, the content of the file F1 is compared with the execution date and time at the time of registration application in place of the information and OS information specific to each information processing device at step 119, and whether or not the information processing device is at the time of registration application. to decide. If it is determined that the information processing device is at the time of registration application, the program recorded in step 121 can be viewed.

  If the movement permission code is present in the program, it can be viewed by the processing of FIG. 16 after moving to the information processing device applied for movement in accordance with FIGS. At this time, viewing cannot be performed on the source information processing device in step 237 of FIG. The movement history stored at this time may be stored in association with the copyrighted work recorded on the video tape by a video deck instead of a medium such as a flexible disk. In this case, it is not necessary to select the data location in steps 253 and 255 of FIGS.

Next, an eighth embodiment of the present invention will be described.
The eighth embodiment of the present invention automatically detects when the function-restricted software 1, the trial-restricted file 61 or the copyright protection software 51, 71, 81, 91, etc. are tampered with or copied. Therefore, it is possible to grasp the fact that fraud has been performed by sending a part or all of the contents or the altered software to the site of the copyright manager or issuing a warning. In addition, functional restrictions are imposed on software that has been altered in this way.

  The copyright protection software 101 includes a fraud detection software 103 for performing processing such as detecting fraud that has been tampered with, collecting software that has been fraudulently, and forcing a function restriction on the fraudulent software. Is incorporated. When it is determined by the fraud detection software 103 that the restriction release command or password of the information FB does not correspond to the function-limited software 1 or the trial-limited file 61, the function-limited software 1 of the file F1 The fraud detection code is recorded in the field of the trial restricted file 61. In addition, for example, it is assumed in advance that the activation icon 43a, the copyright protection software 51, the association between the activation execution files of the function-restricted software 1, and the like start the other activation execution files. Similarly, the fraud detection code is recorded in the column of the function-limited software 1 and the trial-limited file 61 of the file F1.

  Furthermore, the software name extracted from the function-restricted software 1 matches the software name existing in the information FB, but the same applies when the software name is different from that registered in advance. Further, the same applies when the file name, the capacity of the execution file for start-up, the update date and time, and the key data are different from those registered in the copyright protection software 51 or the like. Further, the same applies when the software 1 with restricted function that is started after the copyright protection software 51 or the like performs the identification process or the like is different from that registered in the copyright protection software 51 or the like in advance.

  Further, when the function-restricted software 1 or the like is activated, icons and titles are displayed in the title bar and the resident task. The copyright protection software 51 etc. extracts color digital data values for each pixel with respect to these icons and titles, or screen display portions having characteristics peculiar to the software 1 with this function restriction. However, the digital data values of colors for these icons and titles, or screen display portions having a characteristic characteristic of the function-limited software 1 or the like are registered in advance in the copyright protection software 51 or the like.

  For each pixel, it may be sampled data rather than all pixels. The extraction of the color digital data value is performed when the load factor of the CPU immediately after startup is detected and the load factor falls below the set value, and the color digital data value for the startup initial screen can be extracted. However, it is not limited to this, and arbitrary timing may be sufficient. The extracted digital data value of the color is compared with the digital data value registered in advance in the copyright protection software 51 or the like. Only one type of digital data value to be compared is registered if the initial startup screen is always uniform according to the feature color of the software 1 with limited functions, etc., and there are multiple types of initial startup screens, etc. Multiple types are registered in. When a plurality of types are registered, the plurality of types of digital data values are compared to see if there is a match between the comparison results. Also, multiple types of digital data values may be registered according to the screen resolution, the screen resolution is read from the system, the digital data value according to the resolution is selected, and the screen resolution Alternatively, the digital data value may be obtained by calculation.

  If there is no match as a result of the comparison, the fraud detection code is recorded in the column of the function-limited software 1 and the trial-limited file 61 of the file F1. When these fraud detection codes are recorded, the copyright protection software 51 or the like deletes the restriction release key for the function restricted software 1 or the trial restricted file 61 of the file F1. Therefore, the function restriction of the software 9 without function restriction is continued again. The fraud detection code differs depending on the content of fraud, and the file F1 is recorded with the fraud detection code, the time when the fraud was detected, the drive and directory information in which the function-limited software 1 and the like exist, the software name, etc. The These pieces of information are preferably left as a history.

  If a fraud detection code is recorded, the contents of the file F1 and part or all of the software 1 with function restriction, etc., when connected to the Internet are in the background on the copyright manager side in the background. It should be uploaded automatically. When connected to the Internet, for example, when the function-restricted software 1 or the trial-restricted file 61 is downloaded, an inquiry e-mail is transmitted, or the like. The file may be all of the function-restricted software 1 or the like, or may be a corresponding portion where fraud is detected. On the copyright manager side, fraudulent facts can be confirmed by verifying the contents of the uploaded file F1 and the software 1 with function restriction. Or notify the user of the fact that there was a possibility of fraud or that repair is necessary, and send the software with restricted functions 1 etc. to the copyright manager's site by attaching it to an e-mail. A warning may be issued. Even if a button that can be automatically attached to such an e-mail, sent or uploaded, or stored in a storage medium and mailed is provided on the display screen of the copyright protection software 51 or the like. Good.

  In addition, a set of a plurality of function-limited software 1 and copyright protection software 51 etc. or a software 1 with function restriction previously associated with the copyright protection software 51 is provided on the site of the copyright manager by downloading. Presented as possible. Then, the user may purchase a set of new function-restricted software 1 and copyright protection software 51 or the like from this, or may purchase upgraded version of function-restricted software 1 and copyright protection software 51 or the like. Is possible. In such a case, it is possible to detect fraud as described above with respect to other already downloaded copyright protection software 51, function-restricted software 1 and the like by newly downloaded copyright protection software 51 and the like.

  When newly downloaded copyright protection software 51, function-restricted software 1 or the like is activated or installed, an illegal detection process is performed. First, the copyright protection software 51 or the like reads the contents of the file F1 shown in FIG. 2 to confirm the existence or directory of the other already downloaded copyright protection software 51 or function-limited software 1 or the like. To do. Thereafter, the unauthorized detection processing as described above can be performed in the same manner for the confirmed copyright protection software 51, function-limited software 1 and the like.

  At this time, since it is necessary to perform fraud detection processing based on the latest data, only the copyright protection software 51 having the latest installation execution date and time of the function-limited software 1 or the like may be able to perform fraud detection processing. Alternatively, each activated copyright protection software 51 goes to a directory in which the copyright protection software 51 with the latest installation execution date and time of the software 1 or the like with the function restriction exists, reads the latest data, and based on the data. An unauthorized detection process may be performed. The file F1 may be recorded with the time when the previous fraud detection process was performed, and the fraud detection process may be performed only when a predetermined time has elapsed from this time. Further, each time the latest version of the copyright protection software 51 is installed, the data referenced when detecting fraud is overwritten and updated so as to be the latest, and is always stored in a predetermined directory. Then, when each copyright protection software 51 is activated, an illegal detection process may be performed based on the latest data.

  Further, depending on the contents of the fraud, there may be a case where the corresponding copyright protection software 51 or the like does not exist and the file Fβ and the software 1 with function restriction exist. In this case, when the user purchases a new function-restricted software 1 or the like from a copyright manager site or a recording medium such as a CD-ROM, it is confirmed that this file Fβ exists for a predetermined time or more. It is possible to detect fraud. After confirming the presence of the software 1 with function restriction, it is possible to detect fraud even if the copyright protection software 51 corresponding to the software 1 with function restriction does not exist. When fraud is detected, the copyright protection software 51 or the like deletes the file Fβ. Then, the user may be warned of fraud, or the content may be notified to the copyright manager's site when connected to the Internet.

Alternatively, the copyright protection software 51 in which the file capacity and update date / time of the existing copyright protection software 51, key data, function-restricted software 1 to be activated by the copyright protection software 51, etc. are newly downloaded. The same applies when the data value is different from the registered data value.
Further, when the copyright protection software 51 confirms the fraud detection code by referring to the file F1 or the like, the copyright protection software 51 functions by deleting the restriction release key or the like for the software 1 with function restriction that has been fraudulently detected. While the restriction is continued, a warning message may be displayed for a certain period of time when all other software 1 with restricted functions for which fraud has not been detected is activated.

  This warning message may be, for example, “There is a possibility that the software has been partially broken or has been altered without the consent of the copyright holder. The copyright administrator will cancel the warning or repair it. Please press the designated repair button in the button section 45 after connecting to the Internet. " When the user presses the repair button after connecting to the Internet, the URL of the copyright manager site preset in the browser is input. After that, the contents of the file F1 and part or all of the function-restricted software 1 in which fraud is detected are automatically transmitted to the copyright manager.

  On the copyright manager side, it is determined whether or not this transmission has been performed accurately and necessary data has been transmitted. If it is determined that the transmission is accurate, a specific reception confirmation signal is transmitted from the copyright manager's server to the copyright protection software 51. When the reception confirmation signal is received, the copyright protection software 51 does not display a warning message. If the copyright confirmation software 51 does not confirm this specific reception confirmation signal for a long period of time, the function restriction is applied to all other software 1 with restricted functions that have not been detected illegally after the warning. You may make it apply. At this time, it is possible to perform a simple process of temporarily deleting the restriction release key of the function restricted software 1 or the like.

  In addition, this repair button has a problem of unknown cause due to incompatibility between the software on the user's personal computer or the possibility that the software was partially broken, so it seems that the copyright manager wants to receive a diagnosis. It can be used in any case. In this case, after selecting at least one activation icon 43a such as software to be requested for diagnosis in the activation icon display unit 43, the repair button is pressed. The file F1 and the selected software file are transmitted to the copyright manager.

  As a result, fraud detection of the copyright protection software 51 based on self-diagnosis by the copyright protection software 51 and the function-restricted software 1 (or the trial-restricted file 61) associated with the copyright protection software 51 can be performed. In addition to being possible, when the copyright protection software 51 and the software 1 with function restriction (or the file 61 with trial restriction) associated with the copyright protection software 51 are newly downloaded and executed, the software is executed. An illegal state that has been performed by the copyright protection software 51 on the previously installed copyright protection software 51 and the software 1 with restricted function (or the file 61 with trial restriction) associated with the copyright protection software 51 Is also detected.

  If the copyright protection software 51 itself has been tampered with, it may not be possible to detect fraud by self-diagnosis of the software 1 with restricted function (or the file 61 with trial restriction) associated with the copyright protection software 51. However, fraud can be detected by the copyright protection software 51 related to other software 1 with function restriction (or file 61 with trial restriction) that is separately installed or upgraded. Software and the like are improving day by day, and new and upgraded products are put on the market one after another. Users are likely to purchase these new products. Therefore, the copyright protection software 51 previously installed and the function-limited software 1 (or the trial-limited file 61) associated with the copyright protection software 51 can be protected semipermanently.

  At this time, by sequentially following the history of the file F1, all installed copyright protection software 51 and software 1 with function restriction (or file 61 with trial restriction) associated with this copyright protection software 51, etc. Fraud can be detected. When fraud is detected, a warning is given even when the function-restricted software 1 (or the trial-restricted file 61) or the like unrelated to fraud is used. Even if the software 1 with function restriction (or the file 61 with trial restriction) is deleted from the personal computer by the user, the name and directory of the software 1 with function restriction, the contents of fraud detection, etc. are recorded in the file F1. The warning will continue. This warning cannot be released unless the copyright manager is contacted. When contacting, the copyright manager can recognize the illegal state. Therefore, even if the altered function-limited software 1 or the trial-restricted file 61 is transferred to another person, it is possible to detect an illegal state at any of the transfer destinations.

  It should be noted that the above-described fraud detection is an example, and it is conceivable that various new types of techniques will be applied in the future for tampering and the like. Even in such a case, the copyright manager can acquire and analyze data on this new type of fraud by feedback. For this reason, it is a short time to incorporate in advance a method for detecting and regulating fraud against this new type of trick for new works such as software provided to users through downloads, CD-ROMs, etc., or works to be upgraded. Can be done within a minimum, and damage can be minimized. Since the copyright protection software 51, the function-restricted software 1 and the like have been applied for registration in advance, it is possible to specify a user who is illegally using the software. Since the right to use is granted after the user is authenticated, it is easy to verify.

Next, a ninth embodiment of the present invention will be described.
In the ninth embodiment of the present invention, when an improper writing such as someone else's fault or slander is made on an electronic bulletin board or chat, a warning is given to the writer by e-mail or the writer is notified. It makes it possible to identify the victims and enable them to rescue them quickly.

  In each of the above-described embodiments, a registration applicant is registered in the database of the server for a registration application for the function-limited software 1 or the trial-limited file 61, a registration application necessary for permission to use the WWW homepage, electronic payment, etc. Information, e-mail number, etc. are recorded. On the server side, the writing time is recorded when the entry is sent from the writer. Then, the user I.D received on the server side in relation to this description item. D. Based on the password, the writer of the entry can be extracted from the database. This user I.D. D. The password is recorded with the writing time and stored separately on the server side. As described in the sixth embodiment of the present invention, the user I.D. D. In the case where only the person can use the password, the writer can be accurately identified.

  In addition, it is desirable to add an IP address, cookie information, or the like automatically acquired by the copyright protection software 91 or the like to the registration application items. At this time, the user I.I. D. Even if the password is not requested on the server side, the description item from the database based on the IP address and cookie information received on the server side at this time due to the relationship with the time when the entry item was written. Can be extracted. Furthermore, a warning e-mail can be immediately sent to the writer. If the warning does not indicate a conversion attitude, it is possible to inform the victim of his / her name and address. For this reason, the victim can be quickly remedied.

Next, a tenth embodiment of the present invention will be described.
In the tenth embodiment of the present invention, fingerprints, handwriting, voiceprints, retinas (using fundus blood capillaries), irises, hand sizes and shapes, palm patterns, back blood vessels, facial features Biometrics information based on shape (collation as two-dimensional position data, collation by three-dimensional measurement), keystroke, mouse operation trap, gene information, and the like is used. In addition to using biometric information, an ID-recording medium that can be individually authenticated, such as smart media, a memory stick, and an SD card, may be used as the personal identification data. These ID-added recording media are stored in the recording medium in a form in which an authentication code ID for identifying each recording medium is assigned in advance.

  These biometrics information includes copyright protection software 51, 71, 81, 91, 101 (hereinafter abbreviated as copyright protection software 51), which indicates the presence of drivers such as fingerprint authentication devices and ID-added recording media. After automatic detection, biometrics information, authentication code ID, etc. acquired from the fingerprint authentication device or the copyright protection software 51 are automatically stored in the file F1 in relation to the OS information, or the fingerprint authentication device The personal identification data obtained as a result of the authentication is recorded in the file F1. However, the biometric information and the identity verification data may be recorded in the file F1 by the user himself / herself registering in advance with the copyright protection software 51 or the like.

Further, the biometric information and the like may be used when applying for registration of the function-limited software 1 and the trial-limited file 61 as follows. FIG. 31 shows a registration application method based on personal authentication.
In FIG. 31, in step 601, biometric information such as a fingerprint, an authentication code ID, and the like are registered with the user's personal computer through the fingerprint authentication device and the like. In step 603, when the registration application button 11 is pressed to purchase the function-limited software 1 or the like in the copyright protection software 51 or the like, biometrics information or the like is obtained in step 605 from the fingerprint authentication device or the like (or the copyright protection software 51 or the like). ) Is detected.

  If the biometric information or the like is confirmed between the biometric information registered in step 607 and the detected biometric information or the like, the biometric information is output from the biometric information or fingerprint authentication device in step 609. The personal identification data and the like are stored in the file FN together with installation information, OS information, personal computer specific information, and the like. However, in this case, different biometric information and ID-added recording media may be applied to each function-limited software 1 or the like. If they do not match at step 607, the process returns to step 601 to correct the registration data such as biometric information.

  Thereafter, in step 611, a credit card number is input. In step 613, the file FN data including the biometric information or the personal identification data is transmitted to a site on the Internet provided by the copyright manager together with the credit card number. In the server computer at the site, the credit card number received in step 615 is associated with the file FN data including biometric information or identification data and stored in the database. In addition, since the transmission of the restriction release file 8 and the like are the same as those in the first embodiment of the present invention, the description thereof is omitted. The data of the restriction release file 8 is, for example, as shown in FIG. In step 616, the function-limited software 1 or the like can be purchased. However, when it is confirmed that a driver such as a fingerprint authentication device or an ID-added recording medium is present when applying for registration, request a fingerprint or request an ID-added recording medium. You may make it require registration of such information.

Next, when the user presses the registration application button 11 to purchase again the function-limited software 1 or the like in step 617, biometric information or the like is detected by the fingerprint authentication device or the like in step 619.
If it is confirmed in step 621 that the biometric information or the like registered in the file FN matches the detected biometric information or the like, the biometric information or fingerprint is checked in step 623. The file FN data including the personal identification data output from the authentication device or the like is transmitted to a site on the Internet provided by the copyright manager. If there is a mismatch in step 621, the process returns to step 601 to perform new registration processing in step 622, and the registration data such as biometric information is corrected.

In step 625, the server computer at the site identifies the matching principal data from the file FN data, and extracts the credit card number associated with the principal data. In step 616, the software 1 with limited functions can be purchased with this credit card number.
As described above, the credit card number is only input at the first time, and thereafter, the credit card number is processed after the personal authentication. Since the identity authentication is performed with high accuracy, the credit card number is not used by anyone other than the principal. Further, since biometric information and the like are registered in the file FN, it can be used for personal authentication in each processing flow described later.

Next, an eleventh embodiment of the present invention will be described.
In the eleventh embodiment of the present invention, biometric information registered in the file FN is used for authentication of the registrant, thereby making it possible to make a more accurate determination of the registrant. is there. For example, between steps 73 and 75 in FIG. 5, biometric information or the like is first detected, and then compared with the biometric information or the like registered in the information FB of the restriction release file 8. If YES in step 75, the flow advances to step 69.

  Also, between step 73 and step 75 in FIG. 22, biometric information or the like is first detected, and then compared with the biometric information or the like registered in the information FB of the restriction release file 8. If YES in step 75, the flow advances to step 415.

Next, a twelfth embodiment of the present invention will be described.
In the twelfth embodiment of the present invention, transfer of usage rights in units of personal computers is made possible, and a personal computer with usage rights applies for registration of software 1 with restricted functions using personal authentication such as biometrics information. It can be used only for a person who has made it available or who has made it usable. This is to protect the privacy when used.
In addition, when only the person who applied for registration uses the function-restricted software 1 or the like, it is possible to use the function-restricted software 1 or the like even on a personal computer that is currently restricted by the move process. is there. This is because it is desirable that the purchased person can freely use the software on any personal computer.

Further, the selection of such a processing method can be automatically determined and performed. Further, it is possible to apply such processing to any personal computer regardless of whether or not there is an internet connection.
The operation of the twelfth embodiment of the present invention will be described below using FIG.
In step 651, the copyright protection software 51 or the like automatically detects the presence of a driver such as a fingerprint authentication device or an ID-added recording medium. When the presence is not detected, the restriction process that does not use the personal authentication based on the biometric information or the like described in step 652 until the ninth embodiment of the present invention is performed. Therefore, it can be used even when there is no fingerprint authentication device or ID-added recording medium, but when a fingerprint authentication device or ID-added recording medium is present, more versatile copyright protection can be achieved as follows. It becomes possible.

If the presence of a driver such as a fingerprint authentication device or a recording medium with an ID is detected, in step 653, the biometric information or identification data of the registration applicant of the function-limited software 1 or the like is registered in the file FN. It is determined whether or not. If it is not registered, in step 652, a restriction process that does not use personal authentication based on biometric information or the like is performed.
If registered, in step 655, the usable setting is made if necessary for a person other than the registration applicant in the unit of each function-restricted software 1 or the like. In this case, it is desirable to set the availability of a person other than the registration applicant under the management of the registration applicant. For example, the registration applicant first opens a third party availability setting screen (not shown). However, the third party availability setting screen is opened only when the detected biometric information or the like matches the biometric information or the like of the registration applicant. Thereafter, additional registration of persons other than the registration applicant is performed on the third party availability setting screen. However, you may make it the setting which can be used for persons other than a registration applicant arbitrarily. Then, the biometric information or identification data of the person who has been made available is stored in the file FN in step 657.

When the function-restricted software 1 is activated in step 111, it is determined in step 113 whether the file FN exists. If it exists, in step 663, personal identification data such as an ID is detected from the user's biometric information, an ID-added recording medium, or the like. At this time, an ID-added recording medium or the like is requested by the copyright protection software 51 or the like. On the other hand, if the file FN does not exist, the function restriction is continued in step 115. In step 667, registered biometric information or identity verification data is read from the file FN.
In step 669, a match between the biometric information and the like registered in the file FN and the detected biometric information and the like is determined. If a match is confirmed, it is determined in step 671 whether “only registered applicants are used” is set. The setting “used only by registered applicants” can be set with a button, for example. If a match is not confirmed at step 669, function restriction continues at step 115.

If “used only by registration applicant” is set, it is determined in step 673 whether or not the biometric information detected based on the data of file FN belongs to the registration applicant. If the authentication code ID of the recording medium with ID is registered and stored as the data of the file FN, it is determined whether or not the authentication code ID belongs to the registration applicant. If it is a registration applicant, the process of step 117-step 123 of FIG. 7 is performed, and it starts as software without a function restriction at step 121. Therefore, if “Only registered applicants use” is set in advance and the registered applicant himself / herself is using the function-restricted software 1 or the like, on all computers that can be moved regardless of the movement process. The function-limited software 1 or the like can be used.
When the biometric information detected at step 673 is not for the registration applicant, the function restriction is continued at step 115.

  On the other hand, if “Use only by registered applicant” is not set in step 671, it is determined in step 675 whether or not the personal computer has the function restriction released by the movement process. If it is a personal computer from which the function restriction has been removed, the processing from step 117 to step 123 is performed, and in step 121, it is activated as software without function restriction. Therefore, if the person who can be used in step 655 in advance is a personal computer for which the function restriction has been removed, the function-limited software 1 or the like can be used. On the other hand, if there are drivers such as fingerprint authentication devices and ID-added recording media, even if the personal computer has been released from the function restriction, there is no match between the biometric information and identity verification data such as ID. The software 1 with limited functions cannot be used.

  On the other hand, if it is a personal computer for which the function restriction has not been lifted, a warning such as “Please move the software so that it can be used on this personal computer” is issued in step 677, and the function restriction is made in step 115. To continue. By performing the movement process, the user can use the function-limited software 1 or the like on the personal computer.

Next, FIG. 34 shows a method of starting the software without function restriction 9 in consideration of moving the function restriction release between personal computers. 7 and 33 are denoted by the same reference numerals and description thereof is omitted. FIG. 34 corresponds to FIG. Biometrics information, identification data such as an ID, etc. are transferred from the source personal computer to the destination personal computer via the reference file Q1.
In FIG. 34, in step 652, when a driver such as a fingerprint authentication device or an ID-added recording medium is not detected, it can be set so that it cannot be used in units such as software 1 with function restriction. Also good. As shown in FIG. 34, the same function as that of the movement source personal computer of FIG. 33 can be secured even in the movement destination personal computer.
As described above, transfer of usage rights can be performed on a PC-by-PC basis, and if biometrics information, etc. is available, any PC can be freely used by registration applicants under automatic recognition. it can. It is possible to set a person who can use the unit 1 such as the software with function restriction, and it is possible to deal with various uses while protecting the copyright. All of these processes can be applied to any personal computer regardless of whether or not there is an internet connection.

Next, a procedure for setting “used only by registered applicant” will be described.
In FIG. 35, in step 701, the copyright protection software 51 automatically detects the presence of a driver such as a fingerprint authentication device or an ID-added recording medium. If the presence is not detected, it is not possible to set “used only by registered applicant” in step 703. If detected, it is determined in step 705 whether biometric information or identification data of the registration applicant such as the software 1 with function restriction is registered in the file FN. If it is not registered, it cannot be set to “used only by the registration applicant” in step 703.

  If registered, it is determined in step 707 whether or not the setting button “used only by registered applicant” is pressed. If the setting button has been pressed, movement processing in units of personal computers cannot be performed in step 709. On the other hand, if the setting button has not been pressed, in step 711, movement processing in units of personal computers is performed. In step 713, the contents of the PCN file FN are read. In step 715, it is determined whether or not the function restriction is released for each function-limited software 1 or the like. In the case of a PC whose function restriction has been lifted, in step 717, the function restricted software 1 is set to be usable only by the registered applicant.

Thereafter, in step 719, the use code H only for the user is stored in the file FN together with the set time T1. Here, a setting state of codes that can be used only by the person is simply illustrated in FIG. In FIG. 36, PC1 is a personal computer whose function restriction has been lifted, and PC2 and PC3 are other personal computers that are capable of moving and whose function is currently restricted. When PC2 and PC3 are pre-registered by pressing the movement application button 31 for movement processing, only the person himself / herself uses the release code K as the initial value at the set times T01 and T02. Yes.
In step 721, insertion of a flexible disk or the like is requested. In step 723, the contents of the file FN are stored on a flexible disk or the like. However, instead of inserting a flexible disk or the like, it is possible to connect to a site on the Internet and store the data in the database of this site. In step 725, the use of the function-restricted software 1 or the like is restricted to the person himself / herself.

On the other hand, in the case of a personal computer (PCM) whose function restriction has not been released in step 715, insertion of a flexible disk or the like is requested in step 727. If insertion of a flexible disk or the like is confirmed in step 729, the contents of the file saved in step 731 are read. If the insertion of the flexible disk or the like is not confirmed in step 729, the process proceeds to step 711. However, instead of inserting a flexible disk or the like, it is possible to connect to a site on the Internet and read data from the database of this site.
In step 733, it is determined whether or not the data of the file FM is in an inclusive relationship with the contents of the read file. Here, it is determined whether or not the mutual personal computers are in a relationship capable of movement processing. If it is not possible to move, an error is displayed in step 735. If there is a relationship in which movement processing is possible, it is determined in step 737 whether or not the use code H exists only for the user in the data acquired from the personal computer (PCN) whose function restriction is currently released.

  If the personal use code H does not exist, in step 739, a warning “Please set the personal computer (PCN) on which the function restriction has been released first” is given, and then in step 711 move on. Do not set “Use only for registered applicants” on the PC (PCN) side where the function restriction has been lifted first, and set the PCs (PCM) side on which the function restriction has been removed to “Registered applicants only” Is set to “Use”, the person can use it on a personal computer (PCM) whose function restriction has not been lifted. On the personal computer (PCN) whose function restriction has been lifted, This is because the copyright becomes virtually unprotected because it can be used.

If it is determined in step 737 that the use code H exists only for the user, it is determined in step 741 whether or not the time given the use code H only for the user is newer than the data of the personal computer (PCM). If it is new data, in step 743, the personal computer (PCM) is set to “used only by registration applicant”. In step 745, the code H used only by the user is stored in the file FM together with the set time. In step 747, the contents of the file FM are stored in a flexible disk or the like. In the example of FIG. 36, since the set time T1 of PC1H is newer than the set time T02 of PC2K, PC2K is changed to PC2H at the set time T2.
In step 749, the use of the function-limited software 1 or the like is restricted only to the person himself / herself. On the other hand, if the data is old in step 741, an error is displayed in step 751 because the copyright may not be substantially protected.
In step 753, the user can freely use the function-limited software 1 or the like without moving between the personal computer (PCM) and the personal computer (PCN).

  The setting “used only by registered applicants” may be performed in a group. In the example of FIG. 36, the PC 3 may be a personal computer that does not have a driver such as a fingerprint authentication device or an ID-added recording medium. In this way, the present invention is applicable even if a personal computer that does not have a driver such as a fingerprint authentication device or a recording medium with an ID is included.

Next, a procedure for canceling the setting “used only by registered applicants” will be described.
In FIG. 37, it is determined in step 771 whether or not the setting release button “used only by registered applicant” is pressed. If it has been pressed, the contents of the file FN are read at step 773. In step 775, it is determined whether or not the personal computer has been released from the function restriction in the movement process. In the case of a personal computer (PCM) whose function restriction has not been released, it is determined in step 777 whether or not the use code H exists only in the file FM. If it exists, the use code H for the principal is updated to the use cancellation code K only for the principal in Step 779. However, it is desirable to save as a history.

  In step 781, only the user himself / herself, the use cancellation code K is stored in the file FM together with the release time. In step 783, insertion of a flexible disk or the like is requested. If a flexible disk or the like is inserted in step 785, the contents of the file FM are saved in the flexible disk or the like in step 787. However, instead of inserting a flexible disk or the like, it is possible to connect to a site on the Internet and store the data in the database of this site. In step 789, the use of the function-limited software 1 or the like is restricted. In the example of FIG. 36, PC2H is changed to PC2K at release time T3.

  On the other hand, in the case of a personal computer (PCN) whose function restriction is released in step 775, insertion of a flexible disk or the like is requested in step 791. If the insertion of a flexible disk or the like is confirmed in step 793, the contents of the file stored in step 795 are read. If the insertion of the flexible disk or the like is not confirmed in step 793, the process proceeds to step 797, and the setting “used only by registration applicant” is continued. However, instead of inserting a flexible disk or the like, it is possible to connect to a site on the Internet and read data from the database of this site.

  In step 801, it is determined whether or not the data of the file FN is in an inclusive relationship with the contents of the read file. Here, it is determined whether or not the mutual personal computers are in a relationship capable of movement processing. If there is no possible relationship for movement processing, an error is displayed in step 803. If there is a relationship that can be transferred, it is determined in step 805 whether or not data for all personal computers for which registration has been applied by transfer is available. If data for all the personal computers is not available, a request for data for other personal computers is made at step 807, and the process proceeds to step 797. If one of the other PCs is set to “Use only by registered applicants” and the function restriction has been lifted, the setting of “Used only by registered applicants” will be canceled. While the personal use of a personal computer (PCM) that has not been released can still be used, on the personal computer (PCN) whose function restriction has been released, a licensed person can use it. This is because it is no longer protected.

  If the data for all the personal computers are collected in step 805, the use cancellation code K exists only for the user in the data acquired from the file FM of the personal computer (PCM) whose function restriction has not been canceled in step 809. It is judged whether or not. If the personal use code H exists in the data of the personal computer (PCM) for which the function restriction has not been released, in step 811, the “personal computer (PCM) for which the function restriction has not been released is registered first”. Please cancel the setting of “Use only by applicants”. Is issued and the process proceeds to Step 797.

  If the personal use release code K exists in the data of the personal computer (PCM) whose function restriction has not been released, in step 813, the time when the personal use release code K is added is the personal computer (PCN). ) Whether the data is newer. If the data is old, an error is displayed in step 817 because the copyright may not be protected. If it is new data, it is determined in step 815 whether or not there is still another personal computer (PCM) whose function restriction has not been released. If it remains, the processing from step 809 is repeated.

After confirming that there is a use-cancellation code K for only the personal computer (PCM) for which the function restriction has not been released, set “Use only for registered applicants” for this personal computer (PCN) in step 821 In step 823, the use-only release code K is stored in the file FN together with the release time. In step 825, the contents of the file FN are stored on a flexible disk or the like. In the example of FIG. 36, PC1H is changed to PC1K at release time T4.

  As described above, in step 827, the subsequent processing is performed by movement in units of personal computers by normal movement processing. In this way, while protecting the copyright and ensuring free use only by the applicant for registration, it is also possible to transfer the usage rights in units of personal computers. It is possible to set the number of people who can use the software with the function restriction in units of 1 and so on, and it is possible to increase the degree of freedom in use and protect privacy. In addition, when using the function-limited software 1 or the like in both the source and destination information processing apparatuses, it is possible to obligate the application of the same ID-added recording medium and the use by the same person. Furthermore, the use of the ID-added recording medium or the like is obligated in the use of the transfer source information processing apparatus, but the use right even if the transfer destination information processing apparatus does not have a driver or the like for the ID-added recording medium. Can be moved and used properly. In this way, it is possible to move not only between information processing apparatuses in which drivers for ID-added recording media and the like exist together, but also between information processing apparatuses in which drivers for ID-added recording media exist and information processing apparatuses that do not exist The degree of freedom increases. An appropriate movement processing method can be automatically selected for such various movement forms.

  10 to 12 have been described on the assumption that the movement data is accumulated as a history. In this regard, in the present embodiment, the information processing apparatus at the movement source and the movement destination is obliged to apply the same ID-added recording medium or use by the same person as a general rule. We decided to see the coincidence of IDs. For this reason, when movement is performed only between information processing apparatuses obliged to apply a recording medium with ID, it is possible not to accumulate movement data as such history. However, by performing such accumulation even between the information processing apparatuses that obligate the application of the ID-added recording medium, between the information processing apparatus in which the driver for the ID-added recording medium exists and the information processing apparatus that does not exist as described above It is possible to move on the Internet while protecting the copyright.

  34. In step 651 and step 652 in FIG. 34, when a driver such as a fingerprint authentication device or an ID-added recording medium is not detected, setting is made so that the function-limited software 1 or the like cannot be used. Although described as being possible, it is also possible to disable the movement process itself as described in FIGS. 54 and 55 below. 54 corresponds to FIG. 8, and FIG. 55 corresponds to FIG. The same elements as those in FIG. 8 and FIG.

  In FIG. 54, in step 1601, the copyright protection software 51 determines whether or not the application of the fingerprint authentication device or the recording medium with ID is obliged when moving. However, this requirement can be selected in advance for each function-limited software 1 or the like. If it is determined in step 1601 that there is no obligation, the process proceeds to step 205. On the other hand, when it is determined to be obligatory, the process proceeds to step 1603, where it is determined whether or not there is a fingerprint authentication device or a driver for an ID-added recording medium in the information processing device for which the transfer application has been made. If there is a driver, the process proceeds to step 205. If the driver does not exist, a message is displayed in step 1605 that the use of a recording medium with an ID or the like is necessary when moving the function-limited software 1 or the like. In step 1607, the movement process cannot be performed, and the movement process ends in step 1609.

As shown in FIG. 55, the same applies to the acceptance of movement. In the case of the software 1 with function restriction and the like that requires application of a fingerprint authentication device or an ID-added recording medium at the time of movement, the movement acceptance is performed. Moving processing cannot be performed except when an ID-added recording medium driver or the like is present in the information processing apparatus. In addition, when the mandatory application of the recording medium with an ID is selected for each function-limited software 1 or the like, the mandatory information is stored in the file F1 via the restriction release file 8. Also good. In this case, the processing in steps 1601 and 1605 to 1609 performed in the case of the transfer application in FIG. 54 is omitted, and in step 1603 there is an ID-added recording medium driver or the like in the information processing apparatus to which the transfer application has been made. In step 207, the confirmation code indicating this is stored. At the time of accepting movement, it is also possible to determine whether or not movement is possible based on FIG. 55 after determining the presence of a confirmation code to that effect.
In step 273 of FIG. 12, the file is updated to the file FN in a state where the authentication code ID and the like are included in the reference file Q1. Further, at this time, it may be determined whether to apply a recording medium with an ID or the like.

Next, a thirteenth embodiment of the present invention is described.
In the thirteenth embodiment of the present invention, usage rights are transferred in units of personal computers via the Internet.
FIG. 38 shows an operation flow for the source personal computer. In step 847, it is determined whether or not the setting for enabling transfer of usage rights in units of personal computers is made via the Internet. It is assumed that the setting is performed in advance by the user when it is desired to transfer the usage rights in units of personal computers via the Internet. If no setting has been made, in step 849, movement in units of personal computers is performed without going through the Internet. Such movement processing is based on the processing of FIGS.

  If the setting has been made, the processing after step 851 is performed. In step 851, the transfer application button is clicked with the copyright protection software 51 of the transfer source personal computer whose function restriction is released. However, in the copyright protection software 51 or the like, only the part of the transfer processing of the usage right for each personal computer may be independent software. In this case, the movement application button is clicked after starting this independent movement processing software.

  In step 853, it is determined whether or not the application is by the registrant of the function-limited software 1 or the like. The determination of the personal authentication is compared between the biometric information of the applicant for registration or the personal identification data (hereinafter also including the authentication code ID of the ID-added recording medium) and the data stored in the file FN. If they do not match, an error is displayed in step 855, and the movement process is not performed. If they match, the data of the file FN is read in step 857. Thereafter, in step 859, the connection to the Internet is made, and in step 861, the data of the file FN is transmitted to a site on the Internet. The data in the file FN includes the right to use the software 1 with function restriction as shown in FIG.

  In step 863, personal authentication is performed at the site. This personal authentication is based on I.D. D. The identity of the person is confirmed when the biometric information and identity verification data of the applicant or password match. However, the identity may be confirmed by cookie data or the like. In step 865, the received transfer application data is stored in the site database. In step 867, a function restriction command is transmitted from the site on the Internet to the personal computer PCN of the movement source. In step 869, the personal computer PCN receives this function restriction command. In step 871, the functions of the function-limited software 1 and the like are limited.

Since such movement processing is performed via the Internet, unlike the case of using a flexible disk or the like, there is no possibility of being destroyed or using previous data. For this reason, data may not be accumulated. Moreover, it is good also as movement in a group lump. However, when the data is accumulated, this processing through the Internet and the processing of FIGS. 8 to 21 performed without going through the Internet and the movement data have commonality. The user can use two types of movement processing methods in a mixed manner as appropriate. For example, if there are other data files that you want to save, you can carry the moving data together on a flexible disk, etc. Depending on the mood at that time, it can be selected.
Further, the personal authentication may be processed using personal computer-specific information or OS information, regardless of the biometric information of the applicant for registration and personal identification data. You may make it use combining both.

  FIG. 40 shows an operation flow for the destination personal computer. In step 877, it is determined whether or not the setting for enabling transfer of usage rights in units of personal computers is made via the Internet. It is assumed that the setting is performed in advance by the user when it is desired to transfer the usage rights in units of personal computers via the Internet. If no setting has been made, in step 879, movement of the personal computer is performed without going through the Internet. Such movement processing is based on the processing of FIGS.

  If the setting has been made, the processing after step 881 is performed. In step 881, the movement acceptance button is clicked with the copyright protection software 51 of the destination personal computer whose function restriction has not been lifted. In step 883, it is determined whether or not the application is by the registrant of the function-limited software 1 or the like. This identity authentication determination is compared between the detected biometric information or identity verification data and the registration applicant's biometric information or identity verification data stored in the file FM.

  If they do not match, an error is displayed in step 885, and the moving process is not performed. If they match, the data of file FM is read in step 887. Thereafter, in step 889, the connection to the Internet is made, and in step 891, the data of the file FM is transmitted to a site on the Internet.

In step 893, personal authentication is performed on the site. This personal authentication is based on I.D. D. The identity of the person is confirmed when the biometric information and identity verification data of the applicant or password match. However, the identity may be confirmed by cookie data or the like. In step 895, after the transfer is accepted, the data of the file FN including the right to use the function-restricted software 1 or the like stored in the site database is transmitted to the transfer destination personal computer. In step 897, this data is received by the destination personal computer. Thereafter, in step 899, the function restriction of the software 1 with function restriction, etc. is released based on the right of use of the software 1 with function restriction, etc., at the destination personal computer.
As described above, the function restriction of the function-limited software 1 or the like is performed on the movement source personal computer, while the function restriction is released on the movement destination personal computer.

Next, a fourteenth embodiment of the present invention is described.
The fourteenth embodiment of the present invention relates to a case where a new personal computer is purchased after the old personal computer has been disposed of in the event of replacement or failure of the personal computer. In such a case, the right of use can be transferred to a new personal computer more appropriately by authenticating the user based on the biometric information and identification data of the applicant for registration.

  In FIG. 41, when both an old personal computer (PCN) before purchase and a new purchased personal computer (PCM) exist in step 901, it is possible to cope with the transfer processing of the usage right described in step 903. On the other hand, if the old personal computer (PCN) is to be disposed of, the new purchase button is first clicked on the old personal computer (PCN) in step 905. In step 907, biometric information, identification data, and the like are detected. Judgment of personal authentication is performed between the biometric information or the identity verification data detected in step 909 and the biometric information or identity verification data of the registration applicant stored in the file FN.

  If they do not match, an error is displayed in step 911 and the movement process is not performed. If they match, after being connected to the Internet in Step 913, the data of the file FN is transmitted to a site on the Internet in Step 915. In step 917, data is received at the site, and in step 919, the data is stored in the site database. In step 920, the data in the file FN of the old personal computer (PCN) is deleted. In step 921, the site issues a disposable password to the old personal computer (PCN). The user records this disposable password.

  In step 923, a new purchase button is clicked on a newly purchased personal computer (PCM). In step 925, biometric information, identity verification data, and the like are detected. Judgment of personal authentication is performed between the biometric information or identification data detected in step 927 and the biometric information or identification data of the registration applicant stored in the file FM.

  If they do not match, an error is displayed in step 911 and the movement process is not performed. If they match, after being connected to the Internet in step 929, a disposable password is entered in the password entry field in step 931. Thereafter, in step 933, the data of the file FM is transmitted to a site on the Internet. In step 935, it is determined whether the data of the file FM and the biometric information of the registration applicant, which is the data of the file FN, or the identity verification data match.

  If they do not match, the movement process is stopped in step 911. If they match, in step 937, information on the personal computer (PCM) newly purchased as the destination personal computer is additionally entered in the data of the file FN at the site to complete the movement code. As a result, as the movement data, for example, PCMS, TS pre-registration information and the latest code indicating that the movement processing is performed at time T in PCN-PCM are added and completed. The completed movement data is transmitted to the personal computer (PCM) in step 939, and the data in the file FM is overwritten on the transmitted data in step 941.

As described above, it is possible to deal with a case where an old personal computer is disposed of in advance in the event of replacement of a personal computer or a failure.
In the above description, the movement data is completed on the site side, and the data information of the file FM of the newly purchased personal computer is updated. However, the data information of the file FM of the newly purchased personal computer and the data information of the restriction release file 8 may be changed to those of the newly purchased personal computer based on personal authentication. The flowchart in this case is shown in FIG.

  In FIG. 42, in step 951, biometric information, identification data, etc. are detected. Judgment of personal authentication is performed between the biometric information or the personal identification data detected in step 953 and the biometric information or personal identification data of the registration applicant stored in the restriction release file 8.

  If they do not match, in step 955, a warning that the applicant is different from the registration applicant is issued, and the processing is stopped. If they match, in step 957, the restriction release file 8 and the data of the newly purchased personal computer file FM are transmitted to a site on the Internet. However, if the old personal computer and the site can be connected to the Internet, transmission to the site may be possible on the assumption that the data of the file FN of the old personal computer has been deleted. In step 959, the data of the restriction release file 8 is received at the site. In step 961, the site determines whether the data of the restriction release file 8 and the biometric information of the registration applicant or the personal identification data that is the data of the file FN stored in advance match.

  If not, the process is stopped at step 955. If they match, in step 963, the data of the restriction release file 8 and the data of the file FN stored in advance are changed to those according to the newly purchased personal computer. The data to be changed is, for example, information unique to a personal computer, OS information, installation information, or the like. However, it is desirable to save the data before the change for fraud detection described later. In step 965, the changed data is received by the newly purchased personal computer and the data is updated.

Next, a fifteenth embodiment of the present invention is described.
In the fifteenth embodiment of the present invention, a countermeasure will be described in the case where it is possible to use the function-limited software 1 or the like on a plurality of personal computers due to fraud.
43, first, in step 981, at the time of application registration from the personal computer PCN, the copyright manager site receives the data of the file FN simultaneously with the registration information. However, it is not limited to the application for registration, and it is desirable to receive it at the time of application for movement and at the time of movement acceptance. In step 983, the data reception time is recorded. In step 985, the data of the file FN is stored in the database of the site together with the reception time. The data transmission time may also be recorded, or the time difference between the copyright manager site and the personal computer PCN may be measured. Even when the data of the file FN is sent by mail, the reception time can be recorded.

  On the other hand, the same applies to other personal computers PCM that can be moved. At the time of application registration from the personal computer PCM, the copyright manager site receives the data of the file FM at the same time as the registration information in step 987. Such data can be received when applying for registration of various applications even when the personal computer PCM is not moving. However, it is not limited to the time of registration application, and it is desirable that it be received at the time of moving application or at the time of moving reception. In step 989, the data reception time is recorded. In step 991, the data of the file FM is stored in the database of the site together with the reception time.

  After that, cookie information and user I.D. D. Then, personal authentication is performed based on a password or the like (or a match between personal computer-specific information and OS information), and history information and the like are extracted from the file FN in step 993. In step 995, history information and the like are extracted from the file FM. In step 996, the history information of the file FM is compared with the history information of the file FN. In step 997, it is determined whether or not there is a match in the registered data information even with one function-limited software 1 or the like. If there is a matching function-restricted software 1 or the like, the process proceeds to step 998, where the restriction on the use of the personal computer (PCM) for which the use restriction has not been lifted is set to “used only by the applicant for registration”. It is determined whether or not the setting “used only by registered applicant” is canceled on the personal computer (PCN) that is being used. It is also desirable to determine whether or not such a state has occurred between both personal computers in the past history. In such a case, the personal use of the personal computer (PCM) whose function restriction has not been lifted can still be used, while the authorized person can use the personal computer (PCN) whose function restriction has been lifted. This is because the copyright is substantially not protected.

  If the result of determination is YES, a warning message is transmitted to the user in step 999, and use of all applications under the management of the copyright protection software 51 of the personal computer is stopped in step 1001. In step 1003, a necessary file may be automatically transferred to the site side when canceling the use suspension. By analyzing this file on the site side, it is possible to decipher the illegal method and use it for upgrading the copyright protection software 51 or the like that can cope with such an illegal operation.

  If NO as a result of the determination, it is determined in step 1005 whether or not the history information of the file FN and the history information of the file FM are in an inclusive relationship between personal computers whose usage rights can be transferred. . And when it is not in an inclusion relationship, it progresses to Step 999. On the other hand, if there is an inclusion relationship, it is determined in step 1007 whether or not both of the personal computers are in a usable state. This is because when a plurality of personal computers are both usable, it is considered that the copyright is not substantially protected. Whether or not both are in a usable state, for example, with respect to a personal computer (PCM), all the time zones that were permitted to use (from the date and time when the function-limited software 1 or the like is usable to the date and time when the usage is restricted) ) Is first calculated from the history information of the file FM. Subsequently, for the personal computer (PCN) as well, all the time zones that have been made available are calculated from the history information of the file FN. Thereafter, it is determined whether there is an overlapping portion between these time zones. If there is an overlapping part, it can be determined that both computers are in the usable state in this overlapping time zone. At this time, the process proceeds to step 999. On the other hand, if there is no overlapping part in the time zones of both personal computers, the process proceeds to step 1009. In step 1009, it is determined whether or not both biometric information and identity verification data exist. If it exists, it is determined in step 1011 whether the biometric information and the like match. If they match, the registration application process (or movement process) is continued in step 1013. If neither the biometric information nor the identity verification data exists in step 1009, the registration application process (or movement process) is continued in step 1013. If the biometric information and the like do not match at step 1011, the process proceeds to step 999.

  As described above, it is possible to detect and deal with the case where the use of the software 1 with restricted function in a plurality of personal computers is possible due to various frauds. Even when the transfer method of transferring the usage right without using the history of the file FN or the like is adopted, fraud can be detected by comparing the data of both personal computers by the same processing. The above processing can be detected at the time of application for movement, etc., when the movement processing is performed via the Internet. However, even when the movement processing is not performed via the Internet, the new software 1 with function restriction is provided. This can be dealt with by detecting data when applying for registration.

Further, depending on the fraud method, as described below, fraud can be detected by comparing the history of the file FN or the like in only one personal computer. This coping method is more effective when the movement process is performed via the Internet.
In step 1051 of FIG. 44, the data of the file FN is transmitted to the site on the copyright manager side at the time of application for registration of the new function-limited software 1 or the like (at the time of transfer application). In step 1053, this data is received. In step 1055, the reception time is recorded, and in step 1057, the data of the file FN is stored in the site database. The data transmission time may also be recorded, or the time difference between the copyright manager site and the personal computer PCN may be measured. Even when the data of the file FN is sent by mail, the reception time can be recorded.

  Thereafter, in step 1058, the received file FN data is compared with the previously received and saved file FN data. In step 1059, it is determined whether or not there is a match in the registered data information even if the function-limited software 1 or the like is included in the new data and the old data. If there is a matched function-limited software 1 or the like, the process proceeds to step 1060, where it is determined whether the new data includes the old data. If the new data includes the old data, the registration application process (movement application process) is continued in step 1061.

  On the other hand, if the new data does not include the old data, a warning message is sent to the user in step 1063, and then in step 1065, everything under the copyright protection software 51 of the personal computer is managed. The use of the application is stopped. In this case, it is desirable that the necessary file that is illegally detected is transmitted to the site of the copyright manager by the repair button. On the copyright manager side, it is possible to investigate what fraud has been done by investigating the transmitted file and the like. If it is valid, a release key is transmitted to the user. On the user side, when the release key is received, the warning is released.

  Regardless of the comparison due to the inclusion relationship in step 1060, as shown in step 1007 in FIG. 43, the received data of the file FN is different from the data of the file FN previously received and stored. It may be determined whether or not there is an overlapping portion in the usable period.

Next, a sixteenth embodiment of the present invention will be described.
In the sixteenth embodiment of the present invention, as described below, in the case of fraud, it is mandatory to return the right of use from the destination computer to the source computer after a certain period of time. It deals with fraud.
In step 1101 of FIG. 45, the elapsed time after installation is counted for each function-limited software 1 or the like. The elapsed time data is stored in the file FN in step 1103. In step 1105, it is determined whether or not movement has been made. If yes, elapsed time data is also moved in step 1107 during movement processing. In step 1109, the elapsed time is continuously accumulated in the destination personal computer. In step 1111, it is determined whether the elapsed time is equal to or greater than a set value. If it is less than the set value, the process returns to step 1109 and the elapsed time is continuously calculated.

  If it is determined in step 1111 that the elapsed time is equal to or greater than the set value, in step 1113, the registered personal computer such as the function-limited software 1 is displayed, and an instruction is given to temporarily perform the moving process toward the personal computer. Is done. In step 1115, the moving process is performed on the registered personal computer according to the instruction, and when it is normally completed, the elapsed time is reset in step 1117 and the process returns to step 1101. If an illegal operation is performed due to an OS backup process or the like, the migration process is not completed normally. Therefore, after warning in step 1119, the use of the function-limited software 1 or the like is stopped.

If the movement process is not performed in step 1105, it is determined in step 1119 whether the elapsed time is equal to or greater than a set value. If it is less than the set value, the process returns to step 1101 and the elapsed time is continuously calculated.
If it is determined in step 1119 that the elapsed time is equal to or greater than the set value, the elapsed time is reset in step 1117 and the process returns to step 1101.
As described above, it is possible to check whether or not the transfer process is properly performed by making it mandatory to return the use right from the transfer destination personal computer to the transfer source personal computer after a certain period of time.

Next, a seventeenth embodiment of the present invention is described.
In the seventeenth embodiment of the present invention, movement processing can be performed automatically without pressing a movement application button or movement acceptance button.
In FIG. 46, “Move processing is automatically performed” is set in advance in the copyright protection software 51 of the source personal computer, and the destination is registered. The copyright protection software 51 or the like is resident in a personal computer, or after the copyright protection software 51 or the like is once activated, the copyright protection software 51 or the like is terminated even after the use of the software 1 or the like with limited functions is terminated. As long as there is no operation, it will reside on a personal computer. In step 1151, it is determined whether or not this setting has been made. If no setting has been made, a conventional manual movement process is performed in step 1153. On the other hand, if it is set, it is determined in step 1155 whether or not an OS termination operation has been performed. If an end operation has been performed, movement data is created in step 1157. When group batch movement is set, batch movement data is created.

In step 1159, it is determined whether or not a flexible disk or the like exists at a designated location such as a flexible drive. If not, a flexible disk or the like is requested in step 1161. In step 1163, data is saved, and in step 1165, the OS is terminated.
Thereafter, the flexible disk or the like is moved to the destination personal computer. It is assumed that “moving processing is automatically performed” is set in advance in the copyright protection software 51 or the like in the personal computer of the moving destination. The processing of the destination personal computer will be described based on the flowchart of FIG. Instead of moving the flexible disk or the like, the movement processing based on the flowchart of FIG. In this case, the source PC becomes the destination PC.

In FIG. 47, the OS is started in step 1201. In step 1203, it is determined whether or not “Move process automatically” is set. If it is not set, a conventional manual movement process is performed in step 1205. On the other hand, if the setting has been made, the process proceeds to step 1209 when the function-limited software 1 or the like is activated in step 1207 or when the OS is activated. In step 1209, it is determined whether or not a flexible disk or the like exists at the designated location. If not, a flexible disk or the like is requested in step 1211. In step 1213, the data stored on the flexible disk or the like is read, and in step 1215, the movement process is automatically performed.
As described above, the user can easily move along with the movement of the file, for example, without being aware of the movement process. Note that the present invention can be applied in the same manner even when moving processing is performed via a site on the Internet without using a flexible disk or the like.

Next, an eighteenth embodiment of the present invention will be described.
In the eighteenth embodiment of the present invention, the software 1 with function restriction, the file 61 with use restriction, and the like can be downloaded in an encrypted or compressed form on the copyright manager side based on specific key information. The specific key information includes information specific to the personal computer, OS information, installation information, etc., biometrics information of the applicant for registration, information identical to the content of the restriction release file 8 of the personal identification data, or a part of them. Use.

  In FIG. 48, when applying for registration of the function-limited software 1, the usage-restricted file 61, etc., first, in step 1251, biometric information or identification data of the registration applicant is detected. And it is judged whether this detected biometric information etc. correspond with the data previously registered of the file F1. If they match, in step 1253, the biometric information and the like are transmitted to the site on the Internet together with the information of the file F1. In step 1255, an encryption key (or compression key) is generated based on the transmitted biometric information and the like. In step 1257, the function-restricted software 1, the use-restricted file 61, and the like are encrypted (or compressed) using the generated encryption key as a key. However, the associated copyright protection software 51 or the like may not be encrypted.

In step 1259, the encrypted function-restricted software 1 and the use-restricted file 61 are downloaded and stored in the user's personal computer. At this time, the restriction release file 8 is also downloaded and stored at the same time. The restriction release file 8 includes a password. On the other hand, when using the function-restricted software 1, the use-restricted file 61, etc., in step 1251, biometric information or identity verification data of the registration applicant is detected in the same manner. Then, it is determined whether or not the detected biometric information or the like matches data registered in advance in the file F1. If they match, a decryption key (or a decompression key) is generated in step 1261 based on this biometric information and the like. If they do not match, no decryption key is generated. In use, a decryption key is generated each time a match is determined, so that the copyright can be protected more reliably.
The encrypted (or compressed) function-restricted software 1, use-restricted file 61, etc. are decrypted (or decompressed) based on the decryption key (or decompression key), and expanded in the main memory in step 1263. Used, regenerated, etc. The expansion to the main memory is desirably performed only for the executable file. It is desirable that the executable file exists only in the main memory only at the time of execution, and the auxiliary storage device exists in an encrypted (or compressed) format.

In use, reproduction, etc., it is determined whether or not the file F1 exists. If it is determined that the file F1 exists, it is determined whether or not the restriction release key exists in the file F1. If there is a restriction release key, the process proceeds to step 671 in FIG. Therefore, it is determined what has the right to use, and it is determined whether it matches the information unique to the personal computer or the OS information. However, since the encryption key and the decryption key are both generated based on biometric information, which is common data, the restriction release key may be unnecessary. The method of canceling the function restriction is performed by the process of FIG. 29, for example. If the passwords do not match at step 355 of FIG. 29, the function restriction is continued.
As described above, since it becomes possible to use it only by using processing such as decompression and decryption, fraud is hardly performed.

  As for specific key information, biometric information and the like are detected again each time, and then a decompression key and a decryption key are generated. For this reason, when the decompression or the like succeeds, it can be accurately determined that the registration applicant is using the personal computer or the personal computer used at the time of the registration application. Accordingly, the step of comparing both the contents of the restriction release file 8 and the contents of the file F1 as in step 59 of FIG. 5 may be omitted.

In addition, since encryption, decryption, and the like are performed based on specific key information, it is possible to substantially determine the relationship between the three parties, such as the contents of the restriction release file 8, the contents of the file F1, and the software 1 with function restriction. . Based on this determination, the copyrighted software 1 or the like can be changed to the software 9 or the like without function restriction, or the use of the software 9 or the like without function restriction can be permitted to protect the copyright more highly.
Furthermore, when using the software 1 with function restriction, etc., the function can be restricted or released based on the password.

Next, a nineteenth embodiment of the present invention is described.
In the nineteenth embodiment of the present invention, a copyrighted work such as music software reproduced and output by an information processing apparatus such as a personal computer is acquired as digital data, processed again into the form of music software, etc., and the information processing apparatus or other information This is about measures taken when the data is stored in the processing device.
The copyright protection software 71 and the like are resident in the information processing apparatus. The player 65 as the reproduction software is independent of the copyright protection software 71 and the like, and will be described below assuming that there is something that is not associated with anything. However, the same processing can be performed even if the copyright protection software 71 or the like is associated with the player 65.

  In step 1301 of FIG. 49, the player 65 which is reproduction software is activated. In step 1303, it is specified by selecting a file such as music distribution software or a moving image. In step 1305, reproduction is performed. At the same time, the copyright protection software 71 and the like acquire the digital data reproduced and output in step 1307. The acquired digital data is calculated in step 1309. In this calculation, for example, the acquired digital data is integrated (or integrated), and the time from the start time to the end time is counted, or the average value is calculated by dividing the integrated value by the time. Further, a plurality of sampling data of the intro part (or the end part) of the digital data may be extracted and compared with data stored in advance. In step 1311, the data downloaded in advance from the site on the copyright manager side is compared with the data of these calculation results. On the site of the copyright manager side, data of the result calculated in advance in the same manner for each file such as music distribution software or video is prepared and transmitted to the user when the user applies for file registration.

  As a result of the comparison, if they match or fall within a predetermined error range, it is estimated that the file is illegally copied. Then, the process proceeds to step 1313, where it is determined whether or not the file has a copyright. Whether the file is legitimate can be determined by determining whether the file format, file name, file capacity, header information, watermark information, and the like are legitimate. If the result of the comparison in step 1311 is a mismatch or the predetermined error range is exceeded, it is determined that the file has not been illegally copied, and the process returns to step 1303 to reproduce the next file. If it is determined in step 1313 that this file is properly copyrighted, the process returns to step 1303.

  On the other hand, if it is determined in step 1313 that this file is not properly copyrighted, in step 1315 the copyright protection software 71 or the like assumes that the selected file has been illegally copied. Remember. In step 1317, if the copyright protection software 71 or the like is associated with the player 65, the next reproduction is disabled. In step 1319, the use of the software 1 with restricted function under the management of the copyright protection software 71 or the like is stopped. That is, when the copyright protection software 71 or the like has jurisdiction over the music distribution software, the software with function restriction is also provided even when the music distribution software side detects fraud. It is possible to increase the degree of warning to the user by stopping the use of the one side.

On the other hand, when the user presses the repair button in step 1321, the file detected in fraud in step 1323 is transmitted to the site on the copyright manager side. On the copyright manager side, it is possible to investigate what kind of fraud has been done by investigating the transmitted file and the like. If it is valid, a release key is transmitted to the user. On the user side, when the release key is received in step 1325, the warning or the like is canceled in step 1327.
As described above, even when an illegally copied file exists in the information processing apparatus, it is possible to detect the presence and give a warning or the like. Unauthorized detection is possible regardless of the file format.

Next, another method according to the nineteenth embodiment of the present invention will be described.
When the copyright protection software 71 or the like is associated with the player 65, the reproduction in FIG. 49 is not actually reproduced as a sound. For example, when another song is being played on another player 65, this reproduction is performed. In the player 65, another music distribution software is sequentially automatically extracted from the information processing apparatus and played back. Automatic extraction is determined by the file format. It is desirable to process the playback by fast-forwarding. Then, the reproduced digital data may be acquired, and the acquired digital data may be calculated in step 1309. The reproduction in this case is not for listening as a sound, but only for detecting fraud. The detection of fraud continues as long as the music distribution software remains in the information processing apparatus.

Next, a twentieth embodiment of the present invention will be described.
In the twentieth embodiment of the present invention, the copyright protection software 51 and the like, the function-limited software 1 and the trial-limited file 61 stored in one information processing apparatus can be used in a plurality of information processing apparatuses. It is about the case. Such a case occurs, for example, in a school or the like where a plurality of students use the function-restricted software 1 stored on the teacher's personal computer from other personal computers.

FIG. 50 shows a flowchart. Note that the same elements as those in FIG. 24 are denoted by the same reference numerals and description thereof is omitted.
It is assumed that the user has purchased a usage right for the number of units that can use the function-restricted software 1 or the like in advance so that the information processing apparatus can be used by a plurality of information processing apparatuses. The number of units that can be used in parallel is stored in the file F1 in advance.

In FIG. 50, in step 1351, the number of units that can be used in parallel is read. In step 1353, one unit is subtracted from the number of units that can be used in parallel. In step 1355, if the remaining number is one or more, the process proceeds to step 351, and the subsequent activation of the function-limited software 1 or the like is performed. However, if the remaining number becomes zero, the function restriction is continued in step 356. However, for example, when the use of the function-restricted software 1 or the like is completed for one unit, one unit may be added to the remaining number. In this case, the function-limited software 1 or the like can be used with another unit.
As described above, the function-limited software 1 or the like can be used by only the number of information processing apparatuses whose usage rights have been purchased in advance.

Next, a twenty-first embodiment of the present invention will be described.
In the twenty-first embodiment of the present invention, one information-restricted software 1 or the like is registered for one information processing apparatus, and a plurality of registration applications are applied by upgrading the function-restricted software 1 or the like. This is the case when
Such a case is assumed depending on the mode of fraud. FIG. 51 shows a flowchart as a countermeasure.
In step 1401, a registration application for the function-limited software 1 or the like is made to the site. In step 1403, the sales quantity X of the function-limited software 1 or the like is managed for each user in the site.

  Next, a case where the same user wants to purchase an upgraded product such as the function-limited software 1 will be described. In such a case, in step 1405, the personal authentication is performed at the site after being connected to the Internet. For example, the user authentication may be cookie information or user I.D. D. , Based on a password or the like (or a match between personal computer-specific information and OS information). If the personal information matches, a registration application is made to the site for the upgraded product such as the software 1 with function restriction in step 1407. Now, it is assumed that the user wants to apply for Y number of upgraded products such as the software 1 with function restriction.

  In step 1409, the registration application for the number Y is made to the site, and the sales number Y is managed for the upgraded product such as the software 1 with function restriction for each user in the site. When it is determined in step 1411 that the sales quantity X of the function-limited software 1 or the like is smaller than the sales quantity Y of the upgraded product, only registration for X pieces is performed in step 1413. Not done. When it is determined that they are equal or larger, registration is performed for all the Ys for which registration has been applied in step 1415.

Next, a twenty-second embodiment of the present invention is described.
The twenty-second embodiment of the present invention relates to the case where the use of the function-limited software 1 or the trial-limited file 61 is restricted (or stopped) after the use period (for example, 20 days) has elapsed. Such a use period is provided, for example, to promptly apply for registration. The function-limited software 1 or the like is provided on a compact disc or downloaded on the Internet. The function-restricted software 1 or the like may have been purchased (but not registered) by a user at a store or on the net.
A serial number is assigned to the function-limited software 1 or the like. The serial number is provided to prevent duplicate user registration. This serial number is stored in a file or attached as a seal in a form printed on a paper medium. The serial number is preferably encrypted.

  The personal computer which is the information processing apparatus of the user is installed with the software 1 with function restriction and the copyright protection software 51 etc. (and the player 65). The function-limited software 1 or the like may be integrated with or separate from the copyright protection software 51 or the like. In FIG. 52, the installer is activated in step 1431. In step 1433, the current time T1 of the personal computer is extracted. In step 1435, it is determined whether or not a separate end date is provided for the function-limited software 1 or the like. This expiration date is provided, for example, because the software may be upgraded to new software every year or the maintenance service period may be terminated in one year depending on the application of the software 1 with restricted functions, etc. Yes.

  If an end deadline is provided, the end deadline is calculated and set based on the current time T1 already extracted in step 1437. If no end time limit is set in step 1435, the process proceeds to step 1439. In step 1439, a password is generated. However, a password saved in advance in the copyright protection software 51 or the like may be used. In step 1441, the serial number is read from the saved file. Alternatively, the user manually inputs the serial number and character string printed on the sticker. The read or input serial number or password is stored in the file F1 in step 1443. It should be noted that when reading or inputting the serial number, it is desirable to be able to determine whether or not the serial number has been normally input. For this reason, the serial number includes a numerical value for checking in addition to the identification number part for individually identifying the software 1 with function restriction or the like. This numerical value for checking is a numerical value obtained as a result when appropriate arithmetic processing such as addition, subtraction, and multiplication is performed on each digit of the serial number, for example. The copyright protection software 51 or the like checks the identification number portion based on this check numerical value, and if it does not match, it prompts the user to input again. In step 1445, the process by the installer ends.

Next, an operation method when a usage period (for example, 20 days) is set for use of the function-limited software 1 or the like will be described based on the flowchart of FIG.
In step 1451, an activation icon such as software 1 with function restriction is activated. First, the copyright protection software 51 and the like are operated by this activation icon. In step 1501, the current time T2 of the personal computer is extracted. In step 1505, it is determined whether the registration work has been completed. If the restriction release key is not stored in the file F1, the registration is not completed and the process proceeds to step 1461. In step 1461, a registration application screen is displayed by the copyright protection software 51 or the like.

  In step 1463, if the registration button is pressed on this registration application screen, the process proceeds to step 1465. In step 1465, necessary items for registration application are entered on a predetermined screen. In step 1467, the entered items are put on the Internet or a flexible disk together with the file F1 and sent to the site of the copyright manager by mail. In the site of the copyright manager, after receiving these data in step 1469, the serial number is confirmed in step 1471. In step 1473, it is determined whether or not registration with this serial number has already been performed. If there is no registered one, the process proceeds to step 1475, and the restriction release file 8 is transmitted to the user or put on a flexible disk or the like and mailed. The restriction release file 8 preferably includes a serial number. If it is determined in step 61 that the registrant is the original person by comparing the file F1 and the restriction release file 8 in step 59, the restriction release key (or the decryption key or the decompression key) is changed to the restriction release file 8 in step 1477. Is stored in the file F1. In step 1479, by referring to the restriction release key, the function-limited software 1 or the like can be used. This use is based on the processing shown in FIGS. 7, 24, 28, 29, and the like.

  On the other hand, as a result of the determination in step 1473, if registration with the serial number has already been performed, the process proceeds to step 1481 and a notification to that effect is given. In step 1483, a software purchase screen is displayed. If the software purchase button is pressed in step 1485, in step 1487, purchase processing such as entry of necessary items for purchase is performed on a predetermined screen. The entered items are put on the Internet or a flexible disk or the like in step 1489 and sent to the site of the copyright manager by mail. In step 1491, a new serial number is assigned from the site of the copyright manager. This serial number is sent to the user in the restriction release file 8. On the user side, it is desirable to backup this serial number separately on a flexible disk or the like.

  Next, if the restriction release key is stored in the file F1 in step 1505, the registration is completed, and the process proceeds to step 1507. In step 1507, it is determined whether or not it is within a set end deadline (for example, one year). If it is within the expiration date, the process proceeds to step 1479. On the other hand, if the end deadline is exceeded, the process proceeds to step 1513. At this time, the function-limited software 1 or the like is stopped or function-restricted.

On the other hand, if the registration application screen is displayed in step 1461 and the cancel button is pressed in step 1463, the process proceeds to step 1464. In step 1464, T2-T1 is calculated with respect to the time T1 already stored in the file F1 in step 1433, and it is determined whether this calculation result is 0 day or more and 20 days or less. In the case of 0 day or more and 20 days or less, since it is a usage period, the process proceeds to step 1479. Therefore, although it can be officially used for 20 days after the installation of the software 1 or the like with function restriction, a registration application screen is displayed every time it is activated. The user is expected to complete registration during these 20 days.
On the other hand, if the calculation result in step 1464 is less than 0 day or exceeds 20 days, it is outside the usage period, and the process proceeds to step 1513.

Next, a twenty-third embodiment of the present invention is described.
The twenty-third embodiment of the present invention is about copyright protection multiplexing. As shown in FIG. 24 of the third embodiment of the present invention, copyright protection is performed by passing a password from the copyright protection software 51 etc. to each software-restricted software 1 side and judging whether the passwords match. However, in the twenty-third embodiment of the present invention, in addition to such a method, a part of the file (file F10) constituting the software 1 with function restriction (the file 61 with trial restriction) is partially encrypted (or compressed). The file is decrypted (or decompressed, etc.) and used when a match of passwords and a match of unique information such as personal computer specific information, OS information, and system information are determined. However, the file encryption / decryption processing part added in the twenty-third embodiment of the present invention can be used independently of the password match determination shown in FIG.
Hereinafter, a case where an instruction for starting the copyright protection software 51 or the like is incorporated in a part of the program such as the software 1 or the like with each function restriction will be described.

Next, operation | movement of 23rd Embodiment of this invention is demonstrated based on the flowchart of FIG.
FIG. 56 shows a method of encrypting the file F10 at the time of installation by the installer on the user's personal computer 10. The file F10 may be obtained by extracting a part of the program in advance, or is a text data file or the like that originally exists in each function-restricted software 1 or the like and is read by the function-restricted software 1 or the like when used. Also good. The text data file is preferably data such as condition data related to program processing, for example. Since the file F10 can increase the execution speed, it is desirable that the file F10 has a small capacity. Further, it is desirable that a part of the program is extracted from a part to which the function is restricted and is located in the main routine during the processing operation of the program such as the software 1 with function restriction. This is because if the file F10 is set in a portion other than the portion where the function is restricted, a portion that does not operate in the originally usable portion where the function is not restricted is generated during the function restriction mode. In addition, the effect of copyright protection is weakened except for the main routine.

In FIG. 56, in step 2001, the function-restricted software 1 is installed on the user's personal computer by the installer. The copyright protection software 51 or the like may be installed at the same time as the function-restricted software 1 or may be installed separately from the function-restricted software 1.
In step 2003, it is determined whether or not the file F1 exists. If not, in step 2005, personal computer specific information, OS information, system information, etc. are extracted from the personal computer. Then, in step 2007, the file F1 is generated and the personal computer-specific information extracted from the personal computer is stored. Then, the process proceeds to the next step 2009. There are a plurality of personal computer specific information as shown in FIG. 57, but the data may be converted to a hash value. On the other hand, when it is determined in step 2003 that the file F1 already exists, the installation condition setting file is read in step 2009.

  In the installation condition setting file, in addition to the software information such as the product ID and the software name, which are the product numbers of the software 1 with function restriction, whether or not the file F10 exists, the file F10 is specified. At this time, a file encryption setting code is set. Further, a key generation logical value a indicating a logical value for generating a key for encryption and decryption (hereinafter referred to as a unique information key) is defined. The key generation logical value a indicates a logical procedure for generating a unique information key. For example, in this key generation logical value a, what number digit and what number digit are extracted from the head of the unique information data, what kind of calculation is performed, or how this extracted data is processed Logical procedure data such as whether to generate keys by arranging them is shown. The logical procedure may be variable, and command data for this variable may be recorded in the key generation logical value.

However, by specifying the key generation logical value a by a number or the like, one logical procedure for generating the unique information key may be determined. In this case, a plurality of logical procedures for generating the unique information key are prepared, and each logical procedure is programmed in advance corresponding to each key generation logical value. Details of the logical procedure for generating the unique information key will be described later.
Next, in step 2011, the read data is stored in the file F1. In step 2013, as shown in FIG. 57, the key generation logical value a belonging to the function-restricted software 1 is read from the file F1. Thereafter, in step 2015, personal computer specific information stored in the file F1 is read. The personal computer unique information is registered on the copyright manager side as described above, and then returned as the restriction release file 8 to confirm that the unique information matches. Further, the key generation logical value a may be transmitted by being included in the restriction release file 8 from the copyright manager side as the center.

  In step 2017, a unique information key is generated based on personal computer unique information and the like according to the theory indicated by the key generation logical value a. Alternatively, one of a plurality of logical procedures associated with the key generation logical value a may be selected, and a unique information key may be generated based on personal computer unique information or the like according to this theory. The value of the key generation logical value a is different for each function-limited software 1. The unique information key may be generated in consideration of time data and / or random numbers in addition to personal computer unique information and the like. In this case, the generated unique information key is a variable value that does not depend only on the personal computer. The time data and random numbers acquired at this time are stored in the file F1 and used again at the time of decryption.

  When generating the unique information key, the unique information keys 1 to N are rearranged in a predetermined order, or the unique information keys are generated using the result of calculating the unique information 1 to N through a predetermined function. Also good. Also, by specifying a part of the data of the unique information 1 to N (for example, specifying the character number corresponding to the first character from the beginning of each unique information), or by overlapping some of them and mixing them. Thus, a unique information key may be generated. The unique information key is safe because it is generated each time and does not need to be stored. Since the value of the key generation logical value a is also different for each function-limited software 1, it can be difficult to illegally analyze by the third party. If an analysis by a third party is assumed, the algorithm of the key generation logical value a must be analyzed for each function-limited software 1.

  In step 2019, the file F10 is encrypted using the generated unique information key. However, the encryption process may be a process such as compression. The unique information key may be used as a password for processing such as compression. Further, instead of the encryption processing, the file F10 is divided into a plurality of pieces, for example. Then, when used, it may be usable by combining and reproducing in order. Further, the machine language data of the file F10 may be separated into a plurality of files so that the original data can be reproduced by addition (may be other operations such as subtraction).

Next, the operation of each function-limited software 1 will be described.
In the flowchart of FIG. 58, the icon of the software 1 with function restriction is selected in step 2051, and activated by double clicking or the like in step 2053. After the activation, the process proceeds. In step 2055, when a function previously embedded in an appropriate place in the program is called, the copyright protection software 51 and the like operate. However, the copyright protection software 51 or the like may be activated and resident when the personal computer is activated. In step 2057, the product ID is passed from the software 1 with function restriction to the copyright protection software 51 and the like. In step 2059, the file F1 is searched based on this product ID. In step 2061, it is read whether or not a file encryption setting code is set under this product ID. If the file encryption setting code is set, decryption processing of the file F10 from step 2063 is performed. On the other hand, when the file encryption setting code is not set, the decryption processing of the file F10 from step 2063 to step 2087 is not performed, and the processing is passed to step 2089.

In step 2063, it is determined whether or not the function-restricted software 1 has already been registered with the copyright manager. If the function-restricted software 1 is not registered, the function restriction is maintained or stopped in step 2064 without decrypting the file F10 and releasing the function restriction. At this time, registration application of the function-limited software 1 is prompted.
If the function-restricted software 1 has already been registered, a password is acquired from the function-restricted software 1 in step 2065. This password is previously incorporated in the function-limited software 1 side. In step 2067, the password of the function-limited software 1 is extracted from the file F1. In step 2069, the password acquired in step 2065 is compared with the password extracted in step 2067 to determine whether or not they match. If the passwords do not match, in step 2064 the function restriction is maintained or stopped without decrypting the file F10 and releasing the function restriction.

If the passwords match, the personal computer unique information and the like are detected from the personal computer in step 2071 and compared with the unique information stored in the file F1 in step 2073. In step 2075, it is determined whether or not the number of pieces of unique information that coincide is, for example, 50% or more. However, a priority order may be set for the unique information, and it may be determined whether there is a mismatch between the unique information with a high priority. In addition, the unique information 1 to N is given a score having a weight based on the priority order, etc., and whether or not the total score of the matched unique information is equal to or higher than a predetermined ratio with respect to the total score when all match You may judge by. The priority weighting may be set, for example, such that information having a high probability of being used fixedly or information having a serial number or the like is set high. Furthermore, these methods may be combined.
Thus, by determining whether or not the predetermined ratio is exceeded, it is possible to determine the identity even when a part of the personal computer is changed.

In step 2075, if the number of matching unique information is less than 50%, an error occurs in step 2077. However, new unique information may be re-registered with the copyright manager without causing an error. If re-registered, the new unique information is stored in the file F1.
In step 2075, when the number of matching unique information is 50% or more, the process proceeds to step 2079, and the key generation logical value a belonging to the function-limited software 1 is read from the file F1. Thereafter, in step 2081, personal computer specific information stored in the file F 1 is read. As described above, since the personal computer specific information is read from the information stored in the file F1, it can be decrypted even if the actual personal computer specific information is changed due to the change of the parts. Become. When the unique information key is generated in consideration of time data and random numbers in addition to personal computer unique information and the like, the time data and random numbers are also read from the file F1.

  In step 2083, a unique information key is generated based on the personal computer unique information in accordance with the theory indicated by the key generation logical value a. The unique information key need not be stored. In step 2085, the file F10 designated in advance is decrypted using the generated unique information key. However, if the file F10 is subjected to processing such as compression, it is decompressed. The file F10 may be a specific image file, and the content of the file F10 may be embedded in the image file as watermark information. The unique information key is used as a password for processing such as decompression. In step 2087, it is confirmed that the decoding process has been completed.

  Thereafter, when the program processing reaches a predetermined function in step 2089, the product ID is passed from the software 1 with function restriction to the copyright protection software 51 and the like in step 2091. In step 2093, the product ID is searched in the file F1. However, step 2091 and step 2093 are the same as step 2057 and step 2059 and may be omitted. In step 2095, a password belonging to this product ID is extracted. In step 2097, the password is passed from the copyright protection software 51 etc. to the software 1 with function restriction. On the function-limited software 1 side, in step 2099, a comparison is made with a password previously held on the function-limited software 1 side. If they match, the function restriction of the software with function restriction 1 is released in step 2101, and the process proceeds to step 2103 and subsequent steps. The function restriction release routine at this time is processed according to a program previously built in the software 1 with function restriction.

After step 2103, the file F10 is called at a predetermined location shown in step 2105, and the processing of the file F10 is performed in step 2107. When the file F10 is a text data file, this text data file is used here. Thereafter, after predetermined processing is performed, in step 2109, the operation of the software 1 with function restriction is ended by a user operation.
On the other hand, if the passwords do not match in step 2099, the process proceeds to step 2064, and a function restriction maintenance or stop process is performed.
In the present embodiment, the encrypted file F10 belongs to the part where the function is restricted. Therefore, the processing of the file F10 is performed in step 2107 after the function restriction is released in step 2101.

  As described above, the decryption process is performed in advance, and then the decrypted program or file is used. For this reason, analysis by encryption is difficult. Since the file is a part, decryption speed is high. Encryption is encrypted as a unique key based on personal computer-specific information, random numbers, etc., and is difficult to decrypt. It is not decrypted by other personal computers because it is judged to match information unique to personal computers. Further, by changing the key generation logical value a for each product ID, the analysis can be made difficult. The key generation logical value a is safe because it is generated each time and is not stored. If the change in the parts of the personal computer is less than or equal to the predetermined ratio, it is determined that the same personal computer is used, and decryption is possible. Furthermore, the password for decryption is not exposed to the outside and is safe. Since the password is given based on the information unique to the personal computer and the judgment of personal authentication, it can be managed strictly.

Furthermore, since the software 1 with a plurality of function restrictions is collectively managed by the file F1, it is easy to monitor a copyright violation, and it is possible to collectively handle when a copyright violation occurs.
Furthermore, in addition to the password matching determination on the function-limited software 1 side, by encrypting a part or all of the file, multiple protection of copyrights by different methods is possible, and the protection is further tightened.
In the flowchart of FIG. 58, the decryption routine is embedded in the software 1 with function restriction. However, as described in the third embodiment of the present invention, the copyright protection software is activated together with the activation of the icon. At this time, after the decryption processing of the file F10 from step 2055 to step 2087 is performed first, the software 1 with function restriction in step 2053 may be activated. Alternatively, the copyright protection software may be made resident, and the decryption routine of the file F10 may be performed when the personal computer is activated. A plurality of files F10 may be decrypted simultaneously.

Next, another form of encryption of the file F10 will be described.
In the above description, the file F10 is encrypted at the time of installation. However, the file F10 may be encrypted on the center side. Hereinafter, a description will be given with reference to FIG.
In FIG. 59, after the installation of the software 1 with function restriction is performed, if the user wishes to purchase or register the software 1 with function restriction, the software with function restriction on the user's personal computer in step 2151. 1 registration application is made. In step 2153, the file F1 is transmitted from the user's personal computer to the center. In step 2155, the file F1 is received at the center. In step 2157, the key generation logical value a belonging to the function-limited software 1 is designated. The designation at this time is arbitrarily selected from a plurality of key generation logical values manually or automatically. Or you may make it set the value of a as a number or character input.

In step 2159, information specific to the personal computer is read from the file F1. Thereafter, in step 2161, an encryption key is generated based on the personal computer specific information and the like according to the logical procedure specified by the key generation logical value a. In step 2163, the file F10 is encrypted based on the encryption key.
In step 2165, the file F8 including the key generation logical value a is transmitted from the center side to the user's personal computer. At the same time, the file F10 is also transmitted to the user's personal computer. The file F10 is saved under a predetermined directory in step 2167. However, the file F10 may be transmitted together with another file of the software 1 with function restriction that has not been encrypted, and may be overwritten.

Hereinafter, the decoding process and the like are performed as shown in FIG.
The function-restricted software 1 can be similarly applied to a trial-restricted file 61 such as music. If the encryption is applied to a part of the trial restricted file 61 or the like, only that part cannot be viewed. Further, the unique information may be biometric information or identity verification data instead of the unique information or in addition to the unique information. Further, the encryption / decryption portion can be based on a combination of a public key and a secret key, as well as a common key method.
