  In the system 100 for preventing unauthorized use of application software shown in FIG. 1, the application software is recorded and the installer, which is a program necessary for installing the application software, operates the installer included in the header information. It has a distribution recording medium α recorded in a state where necessary operation information has been deleted in advance, and a piece data DB 111 in which the deleted operation information is recorded as piece data d, and the piece data d is communicated with the communication line. Between the distribution management center 110 (distribution means) that can be transmitted via the distribution media 110 and the distribution means 110 that is a device that can use the application software by installing the application software on the distribution recording medium α. Electricity with a function capable of communicating via line β And a slave device 120. Hereinafter, each part will be described in detail.

  The communication line β is a digital line such as an optical communication line or an analog line such as a telephone line, and is used for mutual communication between the distribution management center 110 and the electronic device 120.

  The distribution recording medium α is a general recording medium such as a CD or a DVD. Application software here refers to word processing software, spreadsheet software, image editing software, database software, presentation software, games, Web browsers, e-mail software, and the like. The installer has an installer body and header information of the installer body, and has a configuration in which operation information included in the header information is missing. The operation information is data indicating the address value of the sector to be read at the beginning of the installer body, the size of the installer body, and the like. The header information in which the operation information is missing includes software information such as the software ID assigned to the application software related to the installer and the web address information of the distribution management center 110 in which the piece data d is stored. .

  The distribution management center 110 rents the application software on the distribution recording medium α to the user and collects the rental usage fee from the user under a contract with the copyright holder of the copyrighted work included in the application software. It is a server operated by the person who conducts the business. In the figure, 111 is a piece data DB in which piece data d is recorded in advance, 112 is a control unit such as a computer, 113 is a communication unit for performing communication, 114 is recorded user information, and authentication and accounting based on this The user information DB 115 in which information such as the above is sequentially recorded, 115 is a software DB in which installer operating software is recorded in advance, and 116 is a memory unit such as a hard disk.

  In addition to the basic program such as an operation system as a server, the memory unit 116 includes a user registration interrupt program shown in FIG. 3, an installer operation software download interrupt program (not shown), and a piece data distribution program shown in FIG. Embedded programs etc. are recorded. Although the contents of these programs will be described later, since the programs are processed by the control unit 112, the server functions as the management center 110. The memory unit 116 stores data necessary for user registration processing and data necessary for use application processing.

  A software ID indicating the corresponding application software is added to the piece data d on the piece data DB 111. In this way, the correspondence relationship between the application software on the distribution recording medium α and the piece data d on the piece data DB 111 is made to match using the software ID. Similarly, a user ID of a corresponding user and an installation software ID assigned to each installer operation software are added to the user information on the user information DB. In this way, the correspondence between the user information in the user information DB and each user is matched using the user ID or the installation software ID.

  Before sending piece data d to electronic device 120, distribution management center 110 checks the user ID and password (that is, authenticates) and also checks whether the installation software ID matches. Therefore, the installation software ID is useful for preventing unauthorized use.

  The electronic device 120 is a general-purpose computer used by a user. In the figure, 121 is a control unit such as a CPU, 122 is an output unit such as a monitor or speaker, 123 is an operation unit such as a keyboard or mouse, and 124 is a reproduction copy that reads / writes data from / to a distribution recording medium α. Reference numeral 125 denotes a memory unit such as a hard disk, and 126 denotes a communication unit for performing communication.

In addition to the basic program, installer operation software shown in FIG. 2 is recorded in the memory unit 125. This installer operation software is software downloaded from the distribution management center 110 through the communication line β on the condition of user registration, and is necessary for installing the application software on the distribution recording medium α. .

  Also, in the memory unit 125, the installation software ID assigned to the installer operation software is transmitted from the distribution management center 110 together with the installer operation software and recorded. Further, piece data d transmitted from the distribution management center 110 is recorded in the memory unit 125, and rental information indicating the piece data transmission date and time, rental period, and the like is recorded.

  Although the contents of the installer operation software will be described later, the same software is processed by the control unit 121 so that the computer can function as the electronic device 121.

  The operation of the application software unauthorized use prevention system 100 configured as described above will be described, and the operation of the distribution management center 110, the operation of the electronic device 120, and the contents of each program will be described.

  First, the user accesses the distribution management center 110 via the communication line β by operating the operation unit 123 of the electronic device 120 (the installer operation software shown in FIG. 2 is not downloaded), and requests user registration. I do. In response to this request, the distribution management center 110 processes the user registration interrupt program shown in FIG. 3, and transmits data necessary for user registration to the computer (s21). After that, the user inputs his / her name, address, payment conditions such as “your bank account number or credit card number” according to what the user registration screen shows through the operation unit 123 of the electronic device 120, and this registration data is sent to the communication line β To the distribution management center 110. Then, the distribution management center 110 creates a user ID and password accordingly, and registers the user ID and the password together with the registration data as user information in the user information DB 114 (s22). It transmits to the user's computer via β (s23). Then, the process of the user registration interrupt program is terminated. The user ID and password may be entered by the user himself / herself during user registration.

  Thereafter, the user operates the operation unit 123 of the electronic device 120 to access the distribution management center 110 and input a request for downloading the installer operation software. At this time, a user ID and a password are required. Then, the electronic device 120 transmits the request to the distribution management center 110 through the communication line β. In response to this request, the distribution management center 110 processes the installer operation software download interrupt program, reads out the installer operation software on the software DB 115, and creates the installation software ID. The installer operation software and the installation software ID are transmitted to the user's electronic device 120 via the communication line β. Then, the installation software ID is registered in the user information DB 114 as user information. Then, the installer operation software shown in FIG. 2 is downloaded to the memory unit 125 of the computer and installed. At the same time, the installation software ID is recorded in the memory unit 125.

  In the electronic device 120, the distribution recording medium α is set in the reproduction / copy unit 124 by the user, and when the installer operation software is executed, the installer operation software is displayed on the output unit 122. Then, a menu list indicating application software being rented is displayed on the screen of the installer operation software (s1). That is, application software with a predetermined flag indicating that an application for use has been set is displayed in the menu list. Based on this menu list, it is determined whether or not an application software installation operation has been performed through the operation unit 123 (s2).

  If it is determined that the installation operation has not been performed, it is determined whether or not an operation for reading the distribution recording medium α (DISC LOAD operation) has been performed through the operation unit 123 (s3). When the DISC LOAD operation is performed, a software list indicating application software that has not been applied for use is displayed on the output unit 122 (s4). That is, the software information included in the header information of the installer on the distribution recording medium α is read, and the application software on which the predetermined flag is not set is displayed on the software list among the application software on the distribution recording medium α.

  Thereafter, when the user makes an application for using the application software on the software list, the software information included in the header information of the installer on the distribution recording medium α is read. Based on the WEB address included in the software information, the software ID included in the software information is transmitted to the distribution management center 110 via the communication line β. In this way, the fact that the use application process is performed is transmitted.

  Then, the distribution management center 110 processes the piece data distribution interrupt program shown in FIG. Then, data necessary for the use application process is read from the memory unit 116 and transmitted to the electronic device 120 via the communication line β (s31). Based on this data, the electronic device 120 displays and outputs a use application screen on the output unit 122 (s5).

  Thereafter, the user sequentially inputs or selects rental periods through the operation unit 123 according to the usage application screen (this determines the rental amount). Finally, the user ID and password are entered into the application software on the distribution recording medium α. When the application for use is input through the operation unit 123 (s6), the electronic device 120 switches the display output of the output unit 122 to the authentication screen, and transmits the input application data to the distribution management center 110 via the communication line β. . At this time, the software ID included in the software information of the header information of the installer of the application software related to the application on the distribution recording medium α and the software ID for installation on the memory unit 125 are read out together with the application data. The data is transmitted to the distribution management center 110 (s7).

  Then, the distribution management center 110 confirms the user authentication related to the application (s32). That is, the user information of the user is read from the user information DB 114 with reference to the transmitted user ID, installation software ID, and the like, and it is confirmed whether or not the user is a genuine user. At this time, the distribution management center 110 confirms whether or not the user information DB 114 is prepared in advance with an inappropriate person list with a rental fee non-payment or the like being greater than or equal to a predetermined value, and is not a person corresponding to the inappropriate person list together with the authentication. (Checking this list of inappropriate persons is optional).

  When the distribution management center 110 confirms that the user involved in the application is an unauthorized user or a genuine user but falls under the inappropriate person list, the communication line β is set to reject the user application. To the electronic device 120 (S33). Then, the piece data distribution interrupt program is terminated.

  On the other hand, when it is confirmed that the user concerned with the application is a genuine user and does not correspond to the unsuitable person list, the user on the user information DB 114 of the user is referred with reference to the user installation software ID or the like. While charging is recorded in the information, the piece data DB 111 is searched with reference to the software ID, the piece data d corresponding to the software ID is read, and the user and the rental information indicating the rental period included in the application data are read. Is transmitted to the electronic device 120 via the communication line β as a reply to accept the application (s34). Then, the piece data distribution interrupt program is terminated.

  The billing is calculated based on the user information DB 114 every predetermined period and charged to the bank / card company 130, or directly charged to the user so that the user can pay by transfer or convenience store. . If the distribution management center 110 is connected to the bank / card company 130 via the communication line β, it is of course possible to make an immediate payment.

  Thereafter, when the electronic device 120 receives that the user application is rejected via the communication line β (s8), the electronic device 120 displays and outputs an error message on the output unit 122 (s9). On the other hand, when piece data d or the like is received via the communication line β (a8), a predetermined flag is set, while piece data d and rental information are recorded in the memory unit 125 (s10). At the same time, the piece data transmission date and time is recorded in the memory unit 125 using the clock function of the computer. Then, the menu list is updated and displayed on the output unit 122, and the application software that has obtained the piece data d is displayed in the menu list as being rented. (s1).

  Thereafter, when an installation operation of the application software is performed based on the menu list through the operation unit 123 (s2), the electronic device 120 reads the piece data d on the memory unit 125 and uses the operation information included in the piece data d. Then, the installer related to the application software on the distribution recording medium α is operated, the installer is processed, and the application software is installed in the memory unit 125 (s11). Thereby, the application software can be used. Note that the installer operating software program is terminated when the user performs termination processing.

  In addition to the basic content described above, the installer operation software is resident in the electronic device 120 when the power source of the electronic device 120 is turned on, and the content for calculating the rental period of the application software is added. . In this rental period management, the difference between the piece data transmission date and time and the current date and time is obtained as an elapsed period from the time when piece data d is transmitted, and if this has reached the rental period included in the rental information, the rental period Processing to uninstall the application software installed on the memory unit 125 as being outside by processing the uninstaller attached to the application software or deleting the application software on the memory unit 125 while defeating a predetermined flag It has become.

  As described above, in the unauthorized use prevention system 100 for application software, even if the user tries to install the application software on the distribution recording medium α using the electronic device 120, the distribution management center 110 as an authentic use applicant. Unless the piece data d is obtained, the installer of the application software on the distribution recording medium α cannot be operated. That is, since application software cannot be installed unless piece data d is obtained, it is possible to prevent unauthorized use of application software installed by decrypting a password or the like as in the conventional example. Application software whose rental period has passed will be uninstalled from the electronic device 120, but if you apply for use and you can obtain piece data d on the condition of charging, you can install the application software again. become.

  In addition, even if the distribution recording medium α is copied to another recording medium by the user, the operation information included in the header information is missing in the installer of the application software recorded on the other recording medium. The application software cannot be installed unless piece data d is obtained as a genuine use applicant. That is, in order to install the application software on the other recording medium, it is necessary to use the electronic device 120 to authenticate the distribution management center 110 and pay the rental fee. It is possible to reliably collect charges by using the system.

  In addition, since the application software usage fee is collected by the user when the application software is applied, the distribution recording medium α is distributed free of charge and then charged to the person who applied for the usage. Alternatively, the distribution recording medium α can be sold only for the price related thereto, and then the person who applied for use can be charged. Furthermore, when a plurality of application software is recorded on the distribution recording medium α, only the application software that the user wants to use can be rented. On the other hand, since a person who creates the distribution recording medium α can create the distribution recording medium α on which any application software is recorded without considering the type or field of application software, the distribution recording medium The production cost of α can be reduced.

  Here, a distribution recording medium creating apparatus 140 used to create the distribution recording medium α will be described with reference to FIGS. 1 and 5. FIG. 5 is a flowchart of recording medium creation software executed by a computer which is a distribution recording medium creation apparatus used in the system.

  The distribution recording medium creation device 140 is a device used by the operator of the distribution management center 110 or a person related thereto, and separates the operation information from the header information of the installer and records it in the memory unit 144. The installer in which the information is separated is recorded on a recording medium set together with application software to create a distribution recording medium α. Here, a computer is used.

  In FIG. 1, 141 is an input unit for reading application software from a master disk, 142 is a control unit such as a CPU for processing the recording medium creation software shown in FIG. 5, and 143 can be set with a recording medium such as a CD or DVD. A recording unit 144 for recording application software on the recording medium is a piece data memory for recording piece data d separated from the installer of the application software.

  The contents of the recording medium creation software shown in FIG. 5 will be described below, and the operation of the distribution recording medium creation apparatus 140 will be described. When the power is turned on, the distribution recording medium creation device 140 executes recording medium creation software. A master disk is set manually or automatically in the input unit 141. In addition, a recording medium such as a CD or a DVD is automatically and sequentially set in the recording unit 143.

  First, the application software and the installer of the application software are read from the master disk set by the input unit 141 (s1), the operation information included in the header information of the installer is separated, and the separated operation information is set as piece data d. The data is recorded in the beat data memory 144 (s2). On the other hand, the installer is recorded on a recording medium set in the recording unit 143 together with application software (s3). The piece data d recorded in the piece data memory 144 is recorded on a recording medium and sent to the distribution management center 110. In this way, the distribution recording medium a is created.

  In the unauthorized use prevention system 100 for application software as described above, the application software is recorded and the installer, which is a program necessary for installing the application software, operates the installer included in the header information. Distribution media that has been recorded in a state in which operation information necessary for the operation has been deleted in advance, and a database in which the operation information that has been deleted is recorded, and the operation information can be transmitted via a communication line And an electronic device that can use the application software by installing the application software on the distribution recording medium and has a function capable of communicating with the distribution unit via a communication line. And the use of application software by the user When the insertion is input to the electronic device, the electronic device transmits the application to the distribution unit via the communication line, and the distribution unit transmits the operation information of the installer of the application software related to the application to the distribution unit via the communication line. The electronic device records the operation information in the memory unit, operates the installer on the distribution recording medium using the operation information on the memory unit during the installation operation, and uses the installer to record the distribution. As long as the application software on the medium is installed, any design modification may be performed.

  Therefore, although the application software and the installer are recorded on the distribution recording medium α, it is of course possible to add other information. As other information, it is determined whether or not the installer operation software is installed in the user's electronic device 120. If it is determined that the software is not installed, the software of the distribution management center 110 is automatically displayed. There are programs to access. If this program is recorded, when the user sets the distribution recording medium α obtained in advance in his / her electronic device 120 (the installer operating software is not downloaded), the WEB address of the distribution management center 110 is set. The distribution management center 110 is accessed based on the reading. After that, if the installer operation software is obtained according to the above-described procedure, the application software installer on the distribution recording medium α can be operated.

  The contents of the installer operation software are merely examples, and any design modifications may be made as long as similar contents can be realized. For example, in conjunction with an operation system or the like, an icon indicating application software on the distribution recording medium α displayed by the operation system or the like is input to the distribution management center 110 as an application for use. Can do. In addition, regarding the contents of the rental period management function of the software, the elapsed period from the time when the piece data d is received may be calculated instead of the elapsed period from the time when the application software is installed. The user registration interrupt program, the installer operation software download interrupt program, and the piece data distribution interrupt program are merely examples, and any design modifications may be made as long as the same contents can be realized. It doesn't matter.

  It should be noted that the first embodiment can be redesigned to a system that prevents unauthorized use of application software on the distribution recording medium α transferred to the user for a fee or free of charge instead of rental. Even if it is a case, there exists an advantage similar to the above. The installer operation software used in this case only needs to delete a series of processes according to the rental period. As for the electronic device, the installer operation software may not be downloaded from the distribution management center 110, but a CD or the like may be installed through a recording medium.

  Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 6 is a block diagram of a system for preventing unauthorized use of application software according to the second embodiment of the present invention, including a block diagram of a recording medium creation device for distribution used in the system. Is a flowchart of the installer operation software used in the system, FIG. 8 is a flowchart of a user registration interrupt program processed by the control unit of the distribution management center of the system, and FIG. 9 is a control unit of the distribution management center. It is a flowchart of the interruption program for piece data delivery processed.

  The unauthorized use prevention system 200 of the application software shown in FIG. 6 is necessary for the installer, which is a program necessary for installing the application software, to operate the installer included in the header information while the application software is recorded. Application software DB211 (first database) recorded in a state where various operating information was previously deleted, and piece data DB 216 (second database) in which the deleted operating information was recorded as piece data d A distribution management center 210 that distributes application software and an installer via a communication line, and a server that can communicate with the distribution management center 210 via a communication line, and the application software distributed from the distribution means is installed. It is provided with an electronic device 220 that can be used by being tall. Hereinafter, each part will be described in detail.

  Application software here refers to word processing software, spreadsheet software, image editing software, database software, presentation software, games, Web browsers, e-mail software, and the like. The installer has an installer body and header information of the installer body, and has a configuration in which operation information included in the header information is missing. The operation information is data indicating the address value of the sector to be read at the beginning of the installer body, the size of the installer body, and the like. The header information in which the operation information is missing includes software information such as the software ID assigned to the application software related to the installer and the WEB address information of the distribution management center 210 in which piece data d is stored. .

Distribution management center 210 undertakes a business of renting application software to the user and collecting the usage fee from the user under a contract with the copyright holder of the copyrighted work included in the application software to be distributed. Is a server operated by. In the figure, reference numeral 211 denotes application software and an application software DB recorded in advance in a state where operation information necessary for the installer to operate the installer included in the header information of the installer is missing, 212 is a control unit such as a computer, 213 Is a communication unit for performing communication, 214 is a user information DB in which user information is recorded, and information such as authentication and billing based on the user information DB is sequentially recorded, 215 is a software in which installer operation software is recorded in advance A wear data DB 216, a piece data DB 213 in which piece data d is recorded in advance, and a memory unit 217 such as a hard disk.

  In addition to a basic program such as an operation system as a server, the memory unit 217 includes a user registration interrupt program shown in FIG. 8, an installer operation software download interrupt program (not shown), an application software load interrupt program (not shown), and The piece data distribution interrupt program shown in FIG. 9 is recorded. Although the contents of these programs will be described later, since the programs are processed by the control unit 212, the server functions as a distribution management center. The memory unit 217 stores data necessary for user registration processing and data necessary for use application processing.

  A software ID indicating the corresponding application software is added to piece data d on piece data DB 216. In this way, the correspondence between the application software and the piece data d on the piece data DB 216 is made to match using the software ID. Similarly, a user ID of the corresponding user and an installation software ID are added to the user information on the user information DB 214. In this way, the correspondence between the user information of each user in the user information DB 214 is made to match using the user ID or the installation software ID.

  Before sending piece data d to electronic device 220, distribution management center 210 checks the user ID and password (that is, authenticates) and also checks whether the installation software IDs match. Therefore, the installation software ID is useful for preventing unauthorized use.

  The electronic device 220 is a general-purpose computer used by a user. In the figure, 221 is a control unit such as a CPU, 222 is an output unit such as a monitor or speaker, 223 is an operation unit such as a keyboard or mouse, 224 is a reproduction / copying unit that reads / writes data to / from a recording medium, etc. Is a memory unit such as a hard disk, and 226 is a communication unit for performing communication.

  In addition to the basic program such as an operation system as a computer, installer operation software shown in FIG. 7 is recorded in the memory unit 224. This installer operation software is paid or free software downloaded from the distribution management center 210 through the communication line β on the condition of user registration, and is application software necessary for executing the application software installer. In addition, the memory unit 224 stores information about the WEB address of the distribution management center 210 in which the installation software ID and piece data d assigned to the installer operation software are stored together with the installer operation software. Sent from and recorded. Furthermore, piece of data d transmitted from the distribution management center 210 is recorded in the memory unit 224, and rental information indicating a rental period and the like is recorded.

  The contents of the installer operation software will be described later, but the computer operates as the electronic device 120 because the installer operation software shown in FIG. .

  The operation of the application software unauthorized use prevention system 200 configured as described above will be described, and the operation of the electronic device 2120, the operation of the distribution management center 210, and the contents of each program will be described.

  First, the user operates the operation unit 223 of his / her own electronic device 220 (the installer operation software is not downloaded) to access the distribution management center 210 via the communication line β and requests user registration. . In response to this request, the distribution management center 210 processes the user registration interrupt program shown in FIG. 8, and transmits data necessary for user registration to the electronic device 220 (s21). After that, the user inputs his / her name, address, payment conditions “such as his / her bank account number or credit card number” and the like according to what the user registration screen shows through the operation unit 223 of the electronic device 220, and the registration data is transmitted to the communication line β To the distribution management center 210. Then, the distribution management center 210 creates a user ID and password accordingly, and registers the user ID and the like together with the registration data as user information in the user information DB 214 (s22). It transmits to the user's electronic device 220 via β (s23). Then, the process of the user registration interrupt program is terminated. The user ID and password may be entered by the user himself / herself during user registration.

  Thereafter, the user operates his / her own electronic device 220 to access the distribution management center 210 and input a request for downloading the installer operation software. At this time, the user ID and password are required. Then, the user's electronic device 220 transmits the request to the distribution management center 210 through the communication line β. In response to this request, the distribution management center 210 processes the installer operation software download interrupt program, thereby reading the installer operation software on the software DB 215, while creating the installation software ID, The installer operation software and the installation software ID are transmitted to the user's electronic device 220 via the communication line β. Then, the installation software ID is registered in the user information DB 214 as user information. Then, the installer operation software is downloaded to the memory unit 224 of the electronic device 220 and installed. At the same time, the installation software ID is recorded in the memory unit 224.

  Next, when acquiring the application software, the electronic device 220 accesses the application software download address of the distribution management center 210 according to the operation through the operation unit 223 of the user. Then, the distribution management center 210 processes the application software download interrupt program. Then, the application software list data is transmitted to the electronic device 220. The electronic device 220 displays and outputs a list of application software on the output unit 222 based on this data. When accessing the distribution management center 210, the installer operation software may be executed and then accessed based on the WEB address recorded with the software, or registered by the user in the Internet browser. You may access based on a WEB address.

  Thereafter, the user selects application software to be downloaded from the list of application software through the operation unit 223. Then, the application application download data for the selected application software is transmitted to the distribution management center 210.

  Upon receiving the application data, the distribution management center 210 refers to the software ID included therein, retrieves and reads out the application software corresponding to the software ID and its installer from the application software DB 211, and the electronic device 220. When the electronic device 220 receives the application software or the like, the electronic device 220 records the application software or the like in a registry of the memory unit 224 or a recording medium set in the reproduction / copy unit 225. At the same time, the software name of the application software is recorded in the menu list of the installer operation software on the memory unit 224. In this way, the application software and its installer are acquired. Note that the download of the application software may be acquired by another computer connected to the distribution management center 210 via the communication line β and recorded on a recording medium.

  Thereafter, in the electronic device 220, the installer operation software is executed by the user (when the application software is recorded on the recording medium, the installer operation software is executed while the recording medium is reproduced by the reproduction / copy unit 225. And the installer operation software is displayed and output on the output unit 222. Then, a menu list is displayed on the screen of the installer operation software (s1). This menu list displays the name of the downloaded application software and whether or not the application software is being rented. That is, application software with a predetermined flag indicating that an application for use has been set is displayed as being rented. Then, based on this menu list, it is determined whether or not the rented application software has been installed through the operation unit 223 (s2).

  If it is determined that the installation operation has not been performed, it is determined whether or not an application operation for using application software that is not being rented displayed in the menu list through the operation unit 223 has been performed (s3). As a result, if it is determined that the use application operation has not been performed, it is determined whether or not a recording medium reading operation (DISC LOAD operation) has been performed through the operation unit 223 (s4). When the DISC LOAD operation is performed, a software list indicating application software on a recording medium not recorded in the menu list (that is, downloaded onto the recording medium by another computer or the like) is displayed and output on the output unit 222. (S5). That is, the software information included in the header information of the installer on the recording medium is read, and the application software that does not have a predetermined flag among the application software on the recording medium is displayed in the software list.

  Thereafter, when the user makes an application for use of application software that is not rented on the menu list or application software on the software list (s3 or s6), the header information of the installer of the application software on the memory unit 224 or the recording medium The software ID included in the header information is transmitted to the distribution management center 210 via the communication line β based on the WEB address of the software information included in. In this way, the fact that the use application process is performed is transmitted.

  Then, the distribution management center 210 processes the piece data distribution interrupt program shown in FIG. 9, and transmits data necessary for the use application process to the electronic device 220 via the communication line β (s31). Based on this data, the electronic device 220 displays and outputs a use application screen on the output unit 222 (s7).

  After that, the user inputs or selects the rental period sequentially through the operation unit 223 according to the usage application screen (this automatically determines the rental amount), and finally uses the user ID and password as an application software application. When input is performed through the operation unit 223 (s8), the electronic device 220 switches the display output of the output unit 222 to the authentication screen, and transmits the input application data to the distribution management center 210 via the communication line β. At this time, the software ID of the software information included in the header information of the installer of the application software on the memory unit 224 or the recording medium and the installation software ID on the memory unit 224 are read and distributed together with the application data. The data is transmitted to the management center 210 (s9).

  Then, the distribution management center 210 confirms user authentication related to the application (s32). That is, the user information of the user is read from the user information DB 214 with reference to the transmitted user ID, installation software ID, and the like, and it is confirmed whether or not the user is a genuine user. At this time, the distribution management center 210 confirms whether or not the user information DB 214 is prepared in advance with an inappropriate person list having a predetermined amount of non-payment of rental fees, etc., and is not a person corresponding to the inappropriate person list together with the authentication. (Note that checking the inappropriate person list is optional).

  When the distribution management center 210 confirms that the user involved in the application is an unauthorized user or a genuine user but falls under the inappropriate person list, the distribution management center 210 informs the communication line β that the user application is rejected. Via the electronic device 220 (s33). Thereafter, the piece data distribution interrupt program is terminated.

  On the other hand, if it is confirmed that the user involved in the application is a genuine user and does not correspond to the inappropriate person list, the user on the user information DB 214 of the user is referred to with reference to the user's installation software ID or the like. While charging is recorded in the information, the piece data DB 216 is searched with reference to the software ID, the piece data d corresponding to the software ID is read, and the user application is applied together with the rental information included in the application data for use. An answer to the effect is sent to the electronic device 220 via the communication line β (s34). Thereafter, the piece data distribution interrupt program is terminated.

  Regarding billing, it is charged to the bank / card company 230 based on the user information DB 214 every predetermined period or directly to the user, and the user is made to pay by transfer or convenience store. If the distribution management center 210 is connected to the bank / card company 230 via the communication line β, it is of course possible to make an immediate payment.

  When the electronic device 220 subsequently receives a notification that the user's application is rejected via the communication line β (s10), the electronic device 220 displays and outputs an error message on the output unit 222 (s11).

  On the other hand, when piece data d and rental information are received via the communication line β (s10), a predetermined flag is set, while piece data d and rental information are recorded in the memory unit 224 (s12). At the same time, the piece data transmission date and time is recorded in the memory unit 224 using the clock function of the computer. Then, the menu list is updated and displayed on the output unit 222, and the application software that obtained the piece data d is displayed in the menu list. (s1).

  Thereafter, when an installation operation of application software is performed based on the menu list through the operation unit 223 (s2), the electronic device 220 reads piece data d related to the application software on the memory unit 225, and includes the piece of data in the piece data d The installer related to the application software on the memory unit 225 or the recording medium is operated using the operation information to be installed, and the application software on the memory unit 225 or the recording medium is installed in the memory unit 225 using the installer (s13). Thereby, the application software can be used. Note that the installer operating software program is terminated when the user performs termination processing.

  In addition to the basic content described above, the installer operation software is added with content that resides in the electronic device 220 when the electronic device 220 is turned on and manages the rental period of the application software. Yes. In this rental period management, the difference between the piece data transmission date and time and the current date and time is obtained as an elapsed period from the time when piece data d is transmitted, and if this has reached the rental period included in the rental information, the rental period The application software installed on the memory unit 225 as being outside is processed by uninstalling the uninstaller attached to the application software, and a predetermined flag is set.

  As described above, in the unauthorized use prevention system 200, even if the user tries to install the application software downloaded using the electronic device 220, unless the piece data d is obtained from the distribution management center 210 as an authentic use applicant, The application software cannot be installed. That is, since application software cannot be installed unless piece data d is obtained, it is possible to prevent unauthorized use of application software installed by decrypting a password or the like as in the conventional example. Application software whose rental period has expired will be uninstalled from the electronic device 220. However, if application is made for use and piece data d can be obtained on the condition of charging, the application software can be installed again. become.

  Also, since the downloaded application software and installer and piece data d are recorded in another location on the memory unit 224 or in a recording medium and the memory unit 224, the application software and the like can be simply Even if copied to another recording medium or the like, it cannot be used unless the piece data d is obtained as an authentic use applicant. That is, in order to install the application software on the other recording medium, it is necessary to authenticate the distribution management center 210 and pay the rental fee using the electronic device 220. It is possible to reliably collect charges by using the system.

  Furthermore, since the application software whose rental period has expired is only uninstalled, the data itself such as application software remains on the memory unit 224 or the recording medium. Therefore, if the application for use is made as described above and the piece data d is obtained, the installation can be performed again.

  Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 10 is a block diagram of a system for preventing unauthorized use of application software according to the third embodiment of the present invention, FIG. 11 is a flowchart of software for operating an installer used in the system, and FIG. 12 is used in the system. 3 is a flowchart of an interrupt program for downloading application software.

  The unauthorized use prevention system 300 for application software shown in FIG. 10 has the same configuration as the unauthorized use prevention system 200. The difference is that the contents of the installer operation software recorded in the memory unit 324 of the electronic device 320 (see FIG. 11) and the contents of the interrupt program for downloading application software recorded in the memory unit 317 of the distribution management center 310 are different. (See FIG. 12). Hereinafter, the difference will be described in detail, and the description of overlapping portions will be omitted.

  In the electronic device 320, installer operation software is recorded in the memory unit 324 in the same procedure as in the second embodiment.

  Thereafter, when acquiring the application software, the electronic device 320 accesses the application software download address of the distribution management center 310 according to the operation through the operation unit 323 of the user. Then, the distribution management center 310 processes the application software download interrupt program shown in FIG. Then, data such as a list of application software necessary for the rental application process is transmitted to the electronic device 320 via the communication line β (s21). The electronic device 320 displays and outputs a rental application screen on the output unit 322 based on this data.

  After that, the user inputs or selects the application software to be rented and the rental period sequentially through the operation unit 323 according to the directions on the rental application screen (this automatically determines the rental amount), and finally the user ID and password are applied to the application. When a software rental application is input through the operation unit 323, the electronic device 320 switches the display output of the output unit 322 to the authentication screen, and transmits the input application data to the distribution management center 310 via the communication line β. At this time, the installation software ID on the memory unit 324 is read and transmitted to the distribution management center 210 together with the application data.

  Then, the distribution management center 310 confirms the user authentication related to the application (22). That is, the user information of the user is read from the user information DB 314 with reference to the transmitted user ID, installation software ID, and the like, and it is confirmed whether or not the user is a genuine user. At this time, the distribution management center 310 confirms whether or not the user information DB 314 is prepared in advance with an inappropriate person list with a rental fee non-payment or the like being greater than or equal to a predetermined value, and is not a person corresponding to the inappropriate person list together with the authentication. (Note that checking the inappropriate person list is optional).

  If the distribution management center 310 confirms that the user involved in the application is an unauthorized user or a genuine user but falls under the unsuitable person list, the distribution management center 310 informs the communication line β that the user application is rejected. Then, the data is transmitted to the electronic device 320 (s23).

  On the other hand, when it is confirmed that the user concerned with the application is a genuine user and does not correspond to the inappropriate person list, the application software and its installer are referred to the software ID of the application software. While searching and reading from the software DB 311, the piece data d corresponding to the software ID is searched and read from the piece data DB 316, and the application software, installer and piece data d are accepted together with the rental information to accept the user's application. The response is sequentially transmitted to the electronic device 320 via the communication line β (s24). The billing is recorded in the user information on the user information DB 314 of the user with reference to the user installation software ID or the like.

  The billing is calculated based on the user information DB 314 every predetermined period and charged to the bank / card company 330 or charged directly to the user so that the user can pay by transfer or convenience store. . Further, when the distribution management center 310 is connected to the bank / card company 330 via the communication line β, it is of course possible to make an immediate settlement.

  Thereafter, when electronic device 320 receives a notification that the user's application is rejected via communication line β, electronic device 320 displays and outputs an error message on output unit 322.

  On the other hand, when the application software or the like is received, the application software and the installer are recorded in a registry of the memory unit 324 or a recording medium set in the copying unit 325, while the piece data d and rental information are stored in a predetermined memory unit. It is recorded in a registry for piece data different from the registry in which 324 application software and the like are recorded. At the same time, the piece data transmission date and time is recorded in the memory unit 324 using the clock function of the computer, and the software name of the application software is recorded in the menu list of the installer operation software on the memory unit 324. Then, a predetermined flag is set.

  Thereafter, the installer operation software is executed by the user (when the application software is recorded on the recording medium, the installer operation software is executed while the recording medium is set), and the installer operation is performed. Display software on the output unit 322. Then, a menu list is displayed on the screen of the installer operation software (s1). This menu list displays the name of the application software and the fact that the application software is being rented. That is, the application software with a predetermined flag is displayed as being rented. Then, based on this menu list, it is determined whether or not the rented application software has been installed through the operation unit 323 (s2).

  If it is determined that no installation operation has been performed, it is determined based on the menu list whether or not an application for use of application software that is not being rented has been applied through the operation unit 323 (s3). That is, it is determined whether or not an application for re-rental of application software whose rental period has ended has been applied. As a result, when it is determined that the application for use has been made, the software ID included in the software information is determined based on the WEB address of the software information included in the header information of the installer of the application software on the memory unit 324 or the recording medium. It is transmitted to the distribution management center 310 that the use application process is performed via the communication line β. Then, the distribution management center 310 processes the piece data distribution interrupt program (see FIG. 9). Then, data necessary for the use application process is transmitted to the electronic device 320 via the communication line β (s31). The electronic device 320 displays and outputs a use application screen on the output unit 322 based on this data (s4).

  After that, the user sequentially inputs or selects rental periods through the operation unit 323 according to the usage application screen (this automatically determines the rental amount), and finally operates the user ID and password as an application software application. When input is made through the unit 323 (s5), the electronic device 320 switches the display output of the output unit 322 to the authentication screen, and transmits the input application data to the distribution management center 310 via the communication line β. At this time, the software ID of the software information included in the header information of the installer of the application software on the memory unit 324 or the recording medium and the installation software ID on the memory unit 324 are read and distributed together with the application data. The data is transmitted to the management center 310 (s6).

  Then, the distribution management center 310 confirms the user authentication related to the application (s32). That is, the user information of the user is read from the user information DB 314 with reference to the transmitted user ID, installation software ID, and the like, and it is confirmed whether or not the user is a genuine user. At this time, the distribution management center 310 confirms whether or not the user information DB 314 is prepared in advance with an inappropriate person list with a rental fee non-payment or the like being greater than or equal to a predetermined value, and is not a person corresponding to the inappropriate person list together with the authentication. (Note that checking the inappropriate person list is optional).

  If the distribution management center 310 confirms that the user involved in the application is an unauthorized user or a genuine user but falls under the inappropriate person list, the communication line β is set to reject the user application. To the electronic device 320 (S33). Then, the processing of the piece data delivery interrupt program is terminated.

  On the other hand, when it is confirmed that the user concerned with the application is a genuine user and does not correspond to the unsuitable person list, the user on the user information DB 314 of the user is referred to with reference to the user installation software ID or the like. While charging is recorded in the information, the piece data DB 316 is searched to read piece data d corresponding to the software ID included in the application, and the user's application is accepted together with the rental information included in the application data. As an answer to the electronic device 320 via the communication line β (s34). Then, the processing of the piece data delivery interrupt program is terminated. Note that billing is performed in the same manner as in the second embodiment.

  Thereafter, when the electronic device 320 receives that the user's application is rejected via the communication line β (s7), the electronic device 320 displays and outputs an error message on the output unit 322 (s8).

  On the other hand, when piece data d and rental information are transmitted from the distribution management center 310 as a response to accept the user application (a7), a predetermined flag is set, while piece data d and rental are set. The information is recorded in the piece data registry of the memory unit 324 described above (s9). At the same time, the piece data transmission date and time is recorded in the memory unit 324 using the clock function of the computer. Then, the application software that has updated the menu list and acquired piece data d is displayed and output to the output unit 322 as being rented (s1).

  Thereafter, when an operation for installing the application software being rented is performed based on the menu list through the operation unit 323 (s2), the electronic device 320 reads piece data d related to the application software on the memory unit 324, and the piece data The installer of the application software on the memory unit 324 or the recording medium is operated using the operation information included in d, and the application software on the memory unit 324 or the recording medium is installed in the memory unit 324 using the installer (s10 ) Thereby, the application software can be used. Note that the installer operating software program is terminated when the user performs termination processing.

In addition, the contents for rental period management similar to those in the second embodiment are added to the installer operation software. In this rental period management, the difference between the piece data transmission date and time and the current date and time is obtained as an elapsed period from when the piece data d is transmitted, and if this has reached the rental period included in the rental information, the rental period The application software installed on the memory unit 324 as being outside is processed by uninstalling the uninstaller attached to the application software, and a predetermined flag is defeated.

  In such an unauthorized use prevention system 300, the same effects as the unauthorized use prevention system 200 can be obtained, and the piece data d can be obtained simultaneously with the application software. Compared to the above, the user has the effect of improving usability.

  Regarding the unauthorized use prevention systems 200 and 300, application software is recorded and operation information necessary for an installer, which is a program necessary for installing the application software, to operate the installer included in the header information. Is a server having a first database recorded in a state where the operating software is deleted in advance and a second database in which the operating information thus deleted is recorded, and distributes the application software and the installer via a communication line. A distribution means, and an electronic device that can communicate with the distribution means via a communication line and that can be used by installing application software distributed from the distribution means. Request is an electronic machine The electronic device transmits the request to the distribution means via the communication line, the distribution means transmits the application software and installer according to the request to the electronic device via the communication line, and the electronic device While application software or the like is recorded in the memory unit or recording medium, when an application for use of the application software is input to the electronic device by the user, the electronic device transmits the application to the distribution unit via the communication line, and the distribution unit Transmits the operation information of the installer of the application software related to the application to the electronic device via the communication line, the electronic device records the operation information in the memory unit, and uses the operation information on the memory unit during the installation operation. Run the installer and use the installer to It may be carried out what kind of design modification as long as it is configured to install the Yonsofuto.

  Thus, the distribution management centers 210 and 310 have one application software DB 211 and 311, but may have a plurality. In this case, different types of application software such as game application software in one DB and word processor application software in a second DB may be stored in each DB, or stored in each DB. The application software may be the same, and it may be possible to prevent access from being concentrated on one DB during congestion. The same applies to the piece data DBs 216 and 316. Further, the distribution management centers 210 and 310 have application software DBs 211 and 311, and piece data DBs 216 and 316. It is also possible to install. In this case, the distribution management centers 210 and 310 authenticate the user and then send the WEB addresses of the application software DBs 211 and 311 and the piece data DBs 216 and 316 to the electronic devices 220 and 320. The electronic devices 220 and 320 The application software DBs 211 and 311, and the piece data DBs 216 and 316 may be accessed to obtain the application software and piece data d.

  The application software DBs 211 and 311 record the application software and the installer, but it is of course possible to record them with other information added. As other information, it is determined whether or not installer operation software is installed in the user's electronic devices 220 and 320. If it is determined that the software is not installed, the HP of the distribution management centers 210 and 310 is determined. There are programs that automatically access If this program is recorded, if the user tries to execute the application software obtained in advance on the electronic devices 220 and 320 (the installer operating software is not downloaded), the WEB address of the distribution management centers 210 and 310 And the distribution management centers 210 and 310 are automatically accessed based on this. Thereafter, the installer operation software can be obtained by the above-described procedure.

  The contents of the installer operation software are merely examples, and any design modifications may be made as long as the same contents can be realized. For example, by operating and inputting an icon indicating application software on the memory units 224 and 324 or the recording medium displayed by the operation system or the like in conjunction with the operation system or the like, the distribution management centers 210 and 310 can apply to the distribution management centers 210 and 310 as applications for use. Can be sent. In addition, regarding the rental period management contents of the software, the elapsed period from the time when the application software is installed or the time when the application software is installed is obtained instead of the elapsed period from the time when the piece data d is received. Alternatively, when the elapsed period is reached, the application software stored in the memory unit 225 may be deleted instead of being uninstalled. However, if deleted, no data such as application software remains, so it is necessary to download the application software again. The user registration interrupt program, the installer operation software download interrupt program, and the piece data distribution interrupt program are merely examples, and any design modifications may be made as long as the same contents can be realized. It doesn't matter.

  It should be noted that the second and third embodiments can be redesigned to a system that prevents unauthorized use of application software distributed for a fee or free of charge instead of rental. Has the same merit as For the installer operation software used in this case, it is sufficient to delete the processing when the distributed application software is outside the rental period. Further, regarding the electronic devices 220 and 320, the installer operation software may not be downloaded from the distribution management centers 210 and 310, but a CD or the like may be installed through a recording medium. Of course, a dedicated device can be used instead of a computer.

  First, a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 13 is a block diagram of a system for preventing unauthorized use of application software according to the fourth embodiment of the present invention, including a block diagram of a distribution recording medium creating apparatus used in the system. Is a flowchart of the decryption program execution software used in the system, FIG. 15 is a flowchart of a user registration interrupt program processed by the control unit of the distribution management center of the system, and FIG. 16 is a control of the distribution management center. It is a flowchart of the interruption program for piece data delivery processed by a part.

  The unauthorized use prevention system 400 for application software shown in FIG. 13 includes a distribution recording medium α on which application software and an installer that is a program necessary for installing the application software are recorded, and an application on the distribution recording medium α. An electronic device 420 that can use the application software by installing the software, and a distribution management center 410 that is a server having a function capable of communicating with the electronic device 420 via the communication line β. doing. Hereinafter, each part will be described in detail.

  Note that the communication line β is a digital line such as an optical communication line or an analog line such as a telephone line, and is used for mutual communication between the distribution management center 410 and the electronic device 420.

  The distribution recording medium α is a general recording medium such as a CD and a DVD, and the application software and the installer are recorded in an encrypted state, and the application software and the installer are decrypted for decryption. The program is recorded in a state where execution information necessary for executing the decryption program included in the header information is missing. Application software here refers to word processing software, spreadsheet software, image editing software, database software, presentation software, games, Web browsers, e-mail software, and the like. The installer is a program such as set-up EXE (set up.exe). The decryption program has a program main body and header information of the program main body, and has a configuration in which execution information included in the header information is missing. The execution information is data indicating the address value of the sector to be read at the beginning of the program body, the size of the program body, and the like. The header information of the decryption program includes software information such as the software ID assigned to the application software related to the decryption program and the web address information of the distribution management center 410 in which piece data d is stored. ing.

  The distribution management center 410 rents the application software on the distribution recording medium α to the user and collects the rental usage fee from the user under a contract with the copyright holder of the copyrighted work included in the application software. It is a server operated by a person who conducts business. In the figure, reference numeral 411 denotes a piece data DB preliminarily recorded as piece data d with execution information deleted from the decryption program on the distribution recording medium α, 412 denotes a control unit such as a computer, and 413 denotes a communication unit for communication. 414 is a user information DB in which user information is recorded, and information such as authentication and accounting based on the user information DB is sequentially recorded. 415 is a software DB in which software for executing a decryption program is recorded in advance. 416 is a hard disk. And the like.

  In addition to the basic program such as an operation system as a server, the memory unit 416 includes a user registration interrupt program shown in FIG. 15, a decryption program execution software download interrupt program (not shown), and piece data delivery shown in FIG. An interruption program for use is recorded. Although the contents of these programs will be described later, the server functions as the management center 410 because the program is processed by the control unit 412. The memory unit 416 records data necessary for user registration processing and data necessary for use application processing.

  A software ID indicating the corresponding application software is added to the piece data d on the piece data DB 411. In this way, the correspondence relationship between the application software on the distribution recording medium α and the piece data d on the piece data DB 411 is made to match using the software ID. Similarly, a user ID of a corresponding user and a decryption software ID attached to each decryption program execution software are added to the user information on the user information DB. In this way, the correspondence between the user information in the user information DB and each user is made to match using the user ID or the decryption software ID.

  Before sending piece data d to electronic device 420, distribution management center 410 checks the user ID and password (that is, authenticates) and also checks whether the decryption software IDs match. Therefore, the decryption software ID is useful for preventing unauthorized use.

  The electronic device 420 is a general-purpose computer used by a user. In the figure, 421 is a control unit such as a CPU, 422 is an output unit such as a monitor or speaker, 423 is an operation unit such as a keyboard or mouse, 424 is a reproduction copy that reads / writes data to / from a distribution recording medium α, etc. 425 is a memory unit such as a hard disk, and 426 is a communication unit for performing communication.

In addition to the basic program, the memory unit 425 stores software for executing the decryption program shown in FIG. The decryption program execution software is software downloaded from the distribution management center 410 through the communication line β on the condition of user registration, and is necessary for installing the application software on the distribution recording medium α. It is.

  Also, the memory unit 425 transmits the decryption software ID assigned to the decryption program execution software from the distribution management center 410 together with the decryption program execution software and records it. Furthermore, piece data d transmitted from the distribution management center 410 is recorded in the memory unit 425, and rental information indicating the piece data transmission date and time, rental period, and the like is recorded.

  Although the contents of the decryption program execution software will be described later, the same software is processed by the control unit 421 so that the computer exhibits the function as the electronic device 421.

  The operation of the application software unauthorized use prevention system 100 configured as described above will be described, and the operation of the distribution management center 410, the operation of the electronic device 420, and the contents of each program will be described.

  First, the user accesses the distribution management center 410 via the communication line β by operating the operation unit 423 of the electronic device 420 (the decryption program execution software shown in FIG. 14 is not downloaded), and is registered as a user. Make a request. In response to this request, the distribution management center 410 processes the user registration interrupt program shown in FIG. 15, and transmits data necessary for user registration to the computer (s21). Thereafter, the user inputs his / her name, address, payment conditions “such as his / her bank account number or credit card number” according to what the user registration screen shows through the operation unit 423 of the electronic device 420, and the registration data is transmitted to the communication line β Is transmitted to the distribution management center 410. Then, the distribution management center 410 creates a user ID and password accordingly, and registers the user ID and the like together with the registration data as user information in the user information DB 414 (s22). It transmits to the user's computer via β (s23). Then, the process of the user registration interrupt program is terminated. The user ID and password may be entered by the user himself / herself during user registration.

  Thereafter, the user operates the operation unit 423 of the electronic device 420 to access the distribution management center 410 and input a request for downloading the decryption program execution software. At this time, a user ID and a password are required. Then, the electronic device 420 transmits the request to the distribution management center 410 through the communication line β. In response to this request, the distribution management center 410 processes the decryption program execution software download interrupt program and reads the decryption program execution software on the software DB 415, while decrypting the software ID for decryption. And the decryption program execution software and the decryption software ID are transmitted to the user's electronic device 420 via the communication line β. Then, the decryption software ID is registered in the user information DB 414 as user information. Then, the decryption program execution software shown in FIG. 14 is downloaded and installed in the memory unit 425 of the computer. At the same time, the decryption software ID is recorded in the memory unit 425.

  In the electronic device 420, when the distribution recording medium α is set in the reproduction / copy unit 424 by the user, when the decryption program execution software is executed, the decryption program execution software is output to the output unit 422. Display output. Then, a menu list showing application software being rented is displayed on the screen of the decryption program execution software (s1). That is, application software with a predetermined flag indicating that an application for use has been set is displayed in the menu list. Based on this menu list, it is determined whether or not an application software installation operation has been performed through the operation unit 423 (s2).

  If it is determined that the installation operation has not been performed, it is determined whether or not an operation for reading the distribution recording medium α (DISC LOAD operation) has been performed through the operation unit 423 (s3). When the DISC LOAD operation is performed, a software list indicating application software that has not been applied for use is displayed on the output unit 422 (s4). That is, the software information included in the header information of the decryption program on the distribution recording medium α is read, and the application software on which the predetermined flag is not set among the application software on the distribution recording medium α is displayed in the software list. To do.

  Thereafter, when the user makes an application for use of the application software on the software list, the software information included in the header information of the decryption program on the distribution recording medium α is read. Then, based on the WEB address included in the software information, the software ID included in the software information is transmitted to the distribution management center 410 via the communication line β. In this way, the fact that the use application process is performed is transmitted.

  Then, the distribution management center 410 processes the piece data distribution interrupt program shown in FIG. Then, the data required for the use application process is read from the memory unit 416 and transmitted to the electronic device 420 via the communication line β (s31). The electronic device 420 displays and outputs a use application screen on the output unit 422 based on this data (s5).

  Thereafter, the user sequentially inputs or selects rental periods through the operation unit 423 according to the usage application screen (this determines the rental amount). Finally, the user ID and password are entered into the application software on the distribution recording medium α. When the application for use is input through the operation unit 423 (s6), the electronic device 420 switches the display output of the output unit 422 to the authentication screen, and transmits the input application data to the distribution management center 410 via the communication line β. . At this time, the software ID included in the software information of the header information of the decryption program of the application software related to the application on the distribution recording medium α and the decryption software ID on the memory unit 425 are read out, and the application data To the distribution management center 410 (s7).

  Then, the distribution management center 410 confirms the authentication of the user related to the application (s32). That is, the user information of the user is read from the user information DB 414 with reference to the transmitted user ID, decryption software ID, and the like, and it is confirmed whether or not the user is a genuine user. At this time, the distribution management center 410 confirms whether or not the user information DB 414 is prepared in advance with an inappropriate person list having a predetermined amount of non-payment of the rental fee, and is not a person corresponding to the inappropriate person list together with the authentication. (Checking this list of inappropriate persons is optional).

  If the distribution management center 410 confirms that the user involved in the application is an unauthorized user or a genuine user but falls under the unsuitable person list, the distribution management center 410 notifies the communication line β that the user application is rejected. Via the electronic device 420 (s33). Then, the piece data distribution interrupt program is terminated.

  On the other hand, when it is confirmed that the user involved in the application is a genuine user and does not correspond to the inappropriate person list, the user's decryption software ID or the like is referred to on the user information DB 414 of the user. While charging is recorded in the user information, the piece data DB 411 is searched with reference to the software ID, the piece data d corresponding to the software ID is read, and this is combined with the rental information indicating the rental period included in the application data. A response to accept the user's application is transmitted to the electronic device 420 via the communication line β (s34). Then, the piece data distribution interrupt program is terminated.

  The billing is tabulated based on the user information DB 414 every predetermined period and charged to the bank / card company 430 or charged directly to the user so that the user can pay by transfer or convenience store. . If the distribution management center 410 is connected to the bank / card company 430 via the communication line β, it is of course possible to make an immediate payment.

  Thereafter, when the electronic device 420 receives that the user application is rejected via the communication line β (s8), the electronic device 420 displays and outputs an error message on the output unit 422 (s9). On the other hand, when piece data d or the like is received via the communication line β (a8), a predetermined flag is set, while piece data d and rental information are recorded in the memory unit 425 (s10). At the same time, the piece data transmission date and time is recorded in the memory unit 425 using the clock function of the computer. Then, the menu list is updated and displayed on the output unit 422, and the application software that has obtained piece data d is displayed in the menu list as being rented. (s1).

  Thereafter, when an installation operation of the application software is performed based on the menu list through the operation unit 423 (s2), the electronic device 420 reads the piece data d related to the application software on the memory unit 425 and includes the piece of data in the piece data d The decryption program related to the application software on the distribution recording medium α is executed and processed using the executed information (s11). Thereby, the application software and the installer of the application software are decrypted. Then, the electronic device 420 processes the installer and installs application software in the memory unit 425 (s12). Thereby, the application software can be used. Note that the decryption program execution software program is terminated when the termination process is performed by the user.

  In addition to the basic content described above, the decryption program execution software is resident in the electronic device 420 when the power of the electronic device 420 is turned on, and the content for calculating the rental period of the application software is added. ing. In this rental period management, the difference between the piece data transmission date and time and the current date and time is obtained as an elapsed period from when the piece data d is transmitted, and if this has reached the rental period included in the rental information, the rental period The application software installed on the memory unit 425 as being outside is processed by uninstalling the uninstaller attached to the application software, or the application software on the memory unit 425 is deleted while defeating a predetermined flag It has become.

  As described above, in the unauthorized use prevention system 400 for application software, a decryption program for decrypting application software and an installer can be executed only after obtaining piece data d as a genuine user. . That is, the application software and the installer cannot be decrypted unless the piece data d is obtained as a genuine user. Therefore, it is not necessary to delete the execution information included in the header information of the installer unlike the unauthorized use prevention system 100 (that is, to change the contents of the installer). Even if it is not possible to obtain permission to change the contents of the unauthorized use prevention system 100, it is possible to obtain the same effect.

  A distribution recording medium creation device 440 used to create the distribution recording medium α will now be described with reference to FIGS. 13 and 17. FIG. 17 is a flowchart of recording medium creation software executed by a computer which is a distribution recording medium creation apparatus used in the system.

  The distribution recording medium creation device 440 is a device used by the operator of the distribution management center 410 or a person related thereto, and separates execution information from the decryption program and records it in the piece data memory 445. The decryption program from which the execution information is separated is recorded on a recording medium set together with the application software and the installer to create a distribution recording medium α. Here, a computer is used.

  In the figure, 441 is an input unit for reading application software and the like from the master disk, 442 is a control unit such as a CPU for processing the recording medium creation software shown in FIG. 17, and 443 can be set with a recording medium such as a CD or DVD. A recording unit for recording application software on the recording medium, 444 is a memory unit in which an encrypted application software and a decryption program for decrypting the installer are recorded in advance, and 445 is from the header information of the decryption program This is a piece data memory for recording the separated execution information as piece data d.

  Hereinafter, the contents of the recording medium creation software shown in FIG. 17 will be described, and the operation of the distribution recording medium creation apparatus 440 will be described. The distribution recording medium creation device 440 executes recording medium creation software when the power is turned on. A master disk is set manually or automatically in the input unit 441. In addition, a recording medium such as a CD or a DVD is automatically and sequentially set in the recording unit 443.

  First, the application software and the installer of the application software are read from the master disk set by the input unit 441 (s1), the application software and the installer are encrypted (s2), and recorded on the recording medium set in the recording unit 143. (S3). Then, the decryption program is read from the memory unit 444, the execution information included in the header information of the decryption program is separated (s4), and the separated execution information is recorded in the bead data memory 445 as piece data d ( s5). The piece data d recorded in the piece data memory 445 is recorded on a recording medium and sent to the distribution management center 410. In this way, the distribution recording medium a is created.

  With regard to the unauthorized use prevention system 400 for application software as described above, a distribution recording medium in which the application software and an installer which is a program necessary for installing the application software are recorded, and the application software on the distribution recording medium Is installed, and a distribution means that is a server having a function capable of communicating with the electronic device via a communication line is provided. Execution necessary for executing the decryption program in which at least the installer is encrypted among the recorded application software and the installer and the decryption program for decrypting the installer is included in the header information. information The distribution means has a database in which the execution information that has been deleted is recorded, and the operation information can be transmitted to the electronic device via the communication line. When the application for using the application software is input to the electronic device by the electronic device, the electronic device transmits the application to the distribution means via the communication line, and the distribution means decrypts the installer of the application software related to the application. The execution information of the program is transmitted to the electronic device via the communication line, the electronic device records the execution information in the memory unit, and the decryption on the distribution recording medium is performed using the execution information on the memory unit during the installation operation. Any design modification is acceptable as long as the program is executed and the installer is decrypted. .

  Therefore, although the application software, the installer, and the decryption program are recorded on the distribution recording medium α, it is of course possible to add other information. As other information, it is determined whether or not the decryption program execution software is installed in the user's electronic device 420. If it is determined that the decryption program execution software is not installed, it is automatically sent to the HP of the distribution management center 410. There are programs to access automatically. If this program is recorded, when the user sets the distribution recording medium α obtained in advance in his / her own electronic device 420 (in a state where the decryption program execution software is not downloaded), the WEB of the distribution management center 410 is set. The address is read, and the distribution management center 410 is accessed based on the address. Thereafter, if the decryption program execution software is obtained by the above-described procedure, the installer of the application software on the distribution recording medium α can be operated.

  Further, the content of the decryption program execution software is merely an example, and any design modification may be performed as long as the same content can be realized. For example, in conjunction with an operation system or the like, an icon indicating application software on the distribution recording medium α displayed by the operation system or the like is input to the distribution management center 410 as an application for use. Can do. In addition, regarding the contents of the rental period management function of the software, the elapsed period from the time when the piece data d is received may be calculated instead of the elapsed period from the time when the application software is installed. The user registration interrupt program, decryption program execution software download interrupt program, and piece data distribution interrupt program are merely examples, and any design modifications are possible as long as the same contents can be realized. You can go.

  Note that the fourth embodiment can be redesigned to a system that prevents unauthorized use of application software on the distribution recording medium α that is transferred to the user for a fee or free of charge instead of being rented. Even if it is a case, there exists an advantage similar to the above. The decryption program execution software used in this case only needs to delete a series of processes corresponding to the rental period. As for the electronic device, the decryption program execution software may not be downloaded from the distribution management center 410, but a CD or the like may be installed through a recording medium.

  Next, a fifth embodiment of the present invention will be described with reference to the drawings.

  Application software here refers to word processing software, spreadsheet software, image editing software, database software, presentation software, games, Web browsers, e-mail software, and the like. The installer is a program such as set-up EXE (set up.exe). The decryption program has a program main body and header information of the program main body, and has a configuration in which execution information included in the header information is missing. The execution information is data indicating the address value of the sector to be read at the beginning of the program body, the size of the program body, and the like. Note that the header information of the decryption program includes software information such as the software ID assigned to the application software related to the decryption program and the web address information of the distribution management center 510 in which piece data d is stored. ing.

  In addition to basic programs such as an operation system as a server, the memory unit 517 includes a user registration interrupt program shown in FIG. 20, a software download interrupt program for executing a decryption program (not shown), and an interrupt for loading an application software (not shown). The program and the piece data delivery interrupt program shown in FIG. 21 are recorded. Although the contents of these programs will be described later, since the programs are processed by the control unit 512, the server functions as a distribution management center. The memory unit 517 stores data necessary for user registration processing and data necessary for use application processing.

  A software ID indicating the corresponding application software is added to piece data d in piece data DB 516. In this way, the correspondence relationship between the application software and the piece data d on the piece data DB 516 is matched using the software ID. Similarly, the user information on the user information DB 514 is added with the user ID of the corresponding user and the decryption software ID assigned to each decryption program execution software. In this way, the correspondence between the user information and the user information of each user in the user information DB 514 is matched using the user ID or the decryption software ID.

  Before sending piece data d to electronic device 520, distribution management center 510 checks the user ID and password (that is, authenticates) and also checks whether the decryption software IDs match. Therefore, the decryption software ID is useful for preventing unauthorized use.

  Electronic device 520 is a general-purpose computer used by a user. In the figure, 521 is a control unit such as a CPU, 522 is an output unit such as a monitor and a speaker, 523 is an operation unit such as a keyboard and a mouse, 524 is a reproduction / copying unit that reads / writes data to / from a recording medium, etc. 524 Is a memory unit such as a hard disk, and 526 is a communication unit for performing communication.

  In addition to the basic program such as an operation system as a computer, the memory unit 524 stores the decryption program execution software shown in FIG. This decryption program execution software is a free or free software downloaded from the distribution management center 510 on the condition of user registration through the communication line β, and is the application software necessary for executing the application software installer. is there. In addition, the memory unit 524 stores the decryption software ID assigned to the decryption program execution software and the WEB address information of the distribution management center 510 storing the piece data d, and the decryption program execution software. At the same time, it is transmitted from the distribution management center 510 and recorded. Further, piece of data d transmitted from the distribution management center 510 is recorded in the memory unit 524, and rental information indicating a rental period and the like is recorded.

  The contents of the decryption program execution software will be described later, but the decryption program execution software shown in FIG. 19 is processed by the control unit 521 so that the computer functions as the electronic device 420. It has become.

  The operation of the unauthorized use prevention system 500 for application software configured as described above will be described, and the operation of the electronic device 520, the operation of the distribution management center 510, and the contents of each program will be described.

  First, the user operates the operation unit 523 of his / her electronic device 520 (the software for executing the decryption program is not downloaded) to access the distribution management center 510 via the communication line β, and requests for user registration. I do. In response to this request, the distribution management center 510 processes the user registration interrupt program shown in FIG. 20, and transmits data necessary for user registration to the electronic device 520 (s21). After that, the user inputs his / her name, address, payment conditions “such as his / her bank account number or credit card number” and the like according to what the user registration screen shows through the operation unit 523 of the electronic device 520, and this registration data is transmitted to the communication line β To the distribution management center 510. Then, the distribution management center 510 creates a user ID and password accordingly, and registers the user ID and the like together with the registration data as user information in the user information DB 514 (s22). It transmits to the user's electronic device 520 via β (s23). Then, the process of the user registration interrupt program is terminated. The user ID and password may be entered by the user himself / herself during user registration.

  Thereafter, the user operates his / her own electronic device 520 to access the distribution management center 510 and input a request for downloading the decryption program execution software. At this time, the user ID and password are required. Then, the user's electronic device 520 transmits the request to the distribution management center 510 through the communication line β. In response to this request, the distribution management center 510 processes the decryption program execution software download interrupt program, thereby reading the decryption program execution software on the software DB 515, while decrypting software execution software. An ID is created, and the decryption program execution software and the decryption software ID are transmitted to the user's electronic device 520 via the communication line β. Then, the decryption software ID is registered in the user information DB 514 as user information. Then, the decryption program execution software is downloaded to the memory unit 524 of the electronic device 520 and installed. At the same time, the decryption software ID is recorded in the memory unit 525.

  Next, when acquiring the application software, the electronic device 520 accesses the application software download address of the distribution management center 510 in accordance with an operation through the operation unit 523 of the user. Then, the distribution management center 510 processes the application software download interrupt program. Then, the application software list data is transmitted to the electronic device 520. The electronic device 520 displays and outputs a list of application software on the output unit 522 based on this data. When accessing the distribution management center 510, after executing the decryption program execution software, it may be accessed based on the WEB address recorded with the software, or the user may access the Internet browser. You may access based on the registered WEB address.

  Thereafter, the user selects application software to be downloaded from the list of application software through the operation unit 523. Then, the application application download data for the selected application software is transmitted to the distribution management center 510.

  When receiving the application data, the distribution management center 510 refers to the software ID included in the distribution management center 510 and retrieves the application software corresponding to the software ID, its installer, and the decryption program from the application software DB 511 and reads them out. And to the electronic device 520. When the electronic device 520 receives the application software or the like, the electronic device 520 records the application software or the like in a registry in the memory unit 524 or a recording medium set in the reproduction / copy unit 525. At the same time, the software name of the application software is recorded in the menu list of the decryption program execution software on the memory unit 524. In this way, application software and the like are acquired. Note that the download of the application software may be acquired by another computer connected to the distribution management center 510 via the communication line β and recorded on a recording medium.

  Thereafter, in the electronic device 520, the decryption program execution software is executed by the user (when the application software is recorded on the recording medium, the decryption program execution software is executed while the recording medium is The decryption program execution software is displayed and output to the output unit 522. Then, a menu list is displayed on the screen of the decryption program execution software (s1). This menu list displays the name of the downloaded application software and whether or not the application software is being rented. That is, application software with a predetermined flag indicating that an application for use has been set is displayed as being rented. Based on this menu list, it is determined whether or not the rented application software has been installed through the operation unit 523 (s2).

  If it is determined that the installation operation has not been performed, it is determined whether or not an application operation for using application software that is not being rented and displayed in the menu list through the operation unit 523 has been performed (s3). As a result, if it is determined that the use application operation has not been performed, it is determined whether or not a recording medium reading operation (DISC LOAD operation) has been performed through the operation unit 523 (s4). When the DISC LOAD operation is performed, a software list indicating application software on a recording medium not recorded in the menu list (that is, downloaded onto the recording medium by another computer or the like) is displayed and output on the output unit 522. (S5). That is, the software information included in the header information of the decryption program on the recording medium is read, and the application software that does not have a predetermined flag among the application software on the recording medium is displayed in the software list.

  Thereafter, when the user makes an application for using application software that is not rented on the menu list or application software on the software list (s3 or s6), a decryption program for the application software on the memory unit 524 or the recording medium Based on the WEB address of the software information included in the header information, the software ID included in the header information is transmitted to the distribution management center 510 via the communication line β. In this way, the fact that the use application process is performed is transmitted.

  Then, the distribution management center 510 processes the piece data distribution interrupt program shown in FIG. 21, and transmits data necessary for the use application process to the electronic device 520 via the communication line β (s31). The electronic device 520 displays and outputs a use application screen on the output unit 522 based on this data (s7).

  Thereafter, the user sequentially inputs or selects rental periods through the operation unit 523 according to the usage application screen (this automatically determines the rental amount), and finally uses the user ID and password as an application software application. When input is performed through the operation unit 523 (s8), the electronic device 520 switches the display output of the output unit 522 to the authentication screen, and transmits the input application data to the distribution management center 510 via the communication line β. At this time, the software ID of the software information included in the header information of the installer of the application software on the memory unit 524 or the recording medium and the decryption software ID on the memory unit 524 are read out together with the application data. The data is transmitted to the distribution management center 510 (s9).

  Then, the distribution management center 510 confirms user authentication related to the application (s32). That is, the user information of the user is read from the user information DB 514 with reference to the transmitted user ID, decryption software ID, and the like, and it is confirmed whether or not the user is a genuine user. At this time, the distribution management center 510 confirms whether or not the user information DB 514 is prepared in advance with an inappropriate person list having a predetermined amount of non-payment of rental fees, etc. and is not a person corresponding to the inappropriate person list together with the authentication. (Note that checking the inappropriate person list is optional).

  When the distribution management center 510 confirms that the user involved in the application is an unauthorized user or a genuine user but falls under the inappropriate person list, the distribution management center 510 indicates that the user application is rejected. Via the electronic device 520 (s33). Thereafter, the piece data distribution interrupt program is terminated.

  On the other hand, when it is confirmed that the user involved in the application is a genuine user and does not correspond to the inappropriate person list, the user information DB 514 of the user is referred to with reference to the user's decryption software ID or the like. While charging is recorded in the user information, the piece data DB 516 is searched with reference to the software ID, the piece data d corresponding to the software ID is read, and the user application is applied together with the rental information included in the application data for use. Is transmitted to the electronic device 520 via the communication line β as a reply to accept (s34). Thereafter, the piece data distribution interrupt program is terminated.

  As for the billing, the bank / card company 230 is billed based on the user information DB 514 every predetermined period, or billed directly to the user so that the user can pay by transfer or convenience store. Further, when the distribution management center 510 is connected to the bank / card company 230 via the communication line β, it is of course possible to make an immediate settlement.

  Thereafter, when electronic device 520 receives a notification that the user's application is rejected via communication line β (s10), it displays and outputs an error message on output unit 522 (s11).

  On the other hand, when piece data d and rental information are received via the communication line β (s10), a predetermined flag is set, while piece data d and rental information are recorded in the memory unit 524 (s12). At the same time, the piece data transmission date and time is recorded in the memory unit 524 using the clock function of the computer. Then, the menu list is updated and displayed on the output unit 522, and the application software that obtained the piece data d is displayed in the menu list. (s1).

  Thereafter, when an installation operation of the application software is performed based on the menu list through the operation unit 523 (s2), the electronic device 520 reads the piece data d related to the application software on the memory unit 525 and includes the piece data d in the piece data d The decryption program related to the application software on the memory unit 525 or the recording medium is executed and processed using the execution information to be processed (s13). Thereby, the application software and the installer of the application software are decrypted. Then, the electronic device 520 processes the installer and installs application software in the memory unit 525 (s14). Thereby, the application software can be used. Note that the decryption program execution software program is terminated when the termination process is performed by the user.

  In addition to the basic content described above, the decryption program execution software includes content that resides in the electronic device 520 when the electronic device 520 is turned on and manages the rental period of the application software. Has been. In this rental period management, the difference between the piece data transmission date and time and the current date and time is obtained as an elapsed period from when the piece data d is transmitted, and if this has reached the rental period included in the rental information, the rental period The application software installed on the memory unit 525 as being outside is processed by uninstalling the uninstaller attached to the application software, and a predetermined flag is turned down.

  As described above, in the unauthorized use prevention system 500, the decryption program for decrypting the application software and the installer can be executed only after obtaining the piece data d as a genuine user. Therefore, it is not necessary to delete the execution information included in the header information of the installer as in the unauthorized use prevention system 200 (that is, to change the contents of the installer). Even if the permission to change the contents cannot be obtained, the same effect as the unauthorized use prevention system 200 can be obtained.

  Next, a sixth embodiment of the present invention will be described with reference to the drawings. FIG. 22 is a block diagram of a system for preventing unauthorized use of application software according to the third embodiment of the present invention, FIG. 23 is a flowchart of decryption program execution software used in the system, and FIG. It is a flowchart of the interruption program for application software download used.

  The unauthorized use prevention system 600 for application software shown in FIG. 22 has the same configuration as the unauthorized use prevention system 500. The difference is that the contents of the decryption program execution software recorded in the memory unit 624 of the electronic device 620 (see FIG. 23) and the interrupt program for downloading the application software recorded in the memory unit 617 of the distribution management center 610 (See FIG. 24). Hereinafter, the difference will be described in detail, and the description of overlapping portions will be omitted.

  In the electronic device 620, decryption program execution software is recorded in the memory unit 624 in the same procedure as in the fifth embodiment.

  Thereafter, when acquiring the application software, the electronic device 620 accesses the application software download address of the distribution management center 610 in accordance with an operation through the operation unit 623 of the user. Then, the distribution management center 610 processes the application software download interrupt program shown in FIG. Then, data such as a list of application software necessary for the rental application process is transmitted to the electronic device 620 via the communication line β (s21). The electronic device 620 displays and outputs a rental application screen on the output unit 622 based on this data.

  After that, the user inputs or selects application software to be rented and the rental period sequentially through the operation unit 623 according to what the rental application screen shows (this automatically determines the rental amount), and finally the user ID and password are applied to the application. When a software rental application is input through the operation unit 623, the electronic device 620 switches the display output of the output unit 622 to the authentication screen, and transmits the input application data to the distribution management center 610 through the communication line β. At this time, the decryption software ID on the memory unit 624 is read out and transmitted to the distribution management center 510 together with the application data.

  Then, the distribution management center 610 confirms the user authentication related to the application (22). That is, the user information of the user is read from the user information DB 614 with reference to the transmitted user ID, decryption software ID, and the like, and it is confirmed whether or not the user is a genuine user. At this time, the distribution management center 610 confirms whether or not the user information DB 614 is prepared in advance with an unsuitable person list having a predetermined amount of non-payment of the rental fee, and is not a person corresponding to the unsuitable person list together with the authentication. (Note that checking the inappropriate person list is optional).

  When the distribution management center 610 confirms that the user involved in the application is an unauthorized user or a genuine user but falls under the unsuitable person list, the distribution management center 610 indicates that the user's application is rejected via the communication line β. To the electronic device 620 (S23).

  On the other hand, if it is confirmed that the user involved in the application is a genuine user and does not fall on the inappropriate person list, the selected application software, its installer and decryption program are assigned the software ID of the application software. While searching and reading from the application software DB 611 for reference, the piece data d corresponding to the software ID is searched and read from the piece data DB 616, and the application software, the installer, the decryption program, and the piece data d together with the rental information The response to accept the user application is sequentially transmitted to the electronic device 620 via the communication line β (s24). The accounting is recorded in the user information on the user information DB 614 of the user with reference to the decryption software ID of the user.

  The billing is calculated based on the user information DB 614 every predetermined period and charged to the bank / card company 630 or charged directly to the user so that the user can pay by transfer or convenience store. . If the distribution management center 610 is connected to the bank / card company 630 via the communication line β, it is of course possible to make an immediate settlement.

  Thereafter, when electronic device 620 receives notification that the user's application is rejected via communication line β, electronic device 620 displays and outputs an error message on output unit 622.

  On the other hand, when the application software or the like is received, the application software, the installer, and the decryption program are recorded in the registry of the memory unit 624 or a recording medium set in the copy unit 325, while the piece data d and the rental information are determined in advance. Recorded in a registry for piece data different from the registry in which the application software and the like in the memory unit 624 is recorded. At the same time, the piece data transmission date and time is recorded in the memory unit 624 using the clock function of the computer, and the software name of the application software is recorded in the menu list of the decryption program execution software on the memory unit 624. Then, a predetermined flag is set.

  Thereafter, the decryption program execution software is executed by the user (when the application software is recorded on the recording medium, the decryption program execution software is executed while the recording medium is set). The decryption program execution software is displayed on the output unit 622. Then, a menu list is displayed on the screen of the decryption program execution software (s1). This menu list displays the name of the application software and the fact that the application software is being rented. That is, the application software with a predetermined flag is displayed as being rented. Based on the menu list, it is determined whether or not the application software being rented has been installed through the operation unit 623 (s2).

  If it is determined that no installation operation has been performed, it is determined based on the menu list whether or not an application for use of application software that is not being rented has been applied through the operation unit 623 (s3). That is, it is determined whether or not an application for re-rental of application software whose rental period has ended has been applied. As a result, if it is determined that the application for use has been made, the software included in the software information based on the WEB address of the software information included in the header information of the decoding program of the application software on the memory unit 624 or the recording medium The ID is transmitted to the distribution management center 610 as the use application process is performed via the communication line β. Then, the distribution management center 610 processes the piece data distribution interrupt program (see FIG. 21). Then, data necessary for the use application process is transmitted to the electronic device 620 via the communication line β (s31). The electronic device 620 displays and outputs a use application screen on the output unit 622 based on this data (s4).

  After that, the user inputs or selects the rental period sequentially through the operation unit 623 according to the usage application screen (this automatically determines the rental amount), and finally operates the user ID and password as an application software application. When input is made via the unit 623 (s5), the electronic device 620 transmits the input application data to the distribution management center 610 via the communication line β while switching the display output of the output unit 622 to the authentication screen. At this time, the software ID of the software information included in the header information of the decryption program of the application software on the memory unit 624 or the recording medium and the decryption software ID on the memory unit 624 are read out, and application data and Together, it is transmitted to the distribution management center 610 (s6).

  Then, the distribution management center 610 confirms the user authentication related to the application (s32). That is, the user information of the user is read from the user information DB 614 with reference to the transmitted user ID, decryption software ID, and the like, and it is confirmed whether or not the user is a genuine user. At this time, the distribution management center 610 confirms whether or not the user information DB 614 is prepared in advance with an unsuitable person list having a predetermined amount of non-payment of the rental fee, and is not a person corresponding to the unsuitable person list together with the authentication. (Note that checking the inappropriate person list is optional).

  When the distribution management center 610 confirms that the user involved in the application is an unauthorized user or a genuine user but falls under the unsuitable person list, the distribution management center 610 indicates that the user's application is rejected via the communication line β. Via the electronic device 620 (s33). Then, the processing of the piece data delivery interrupt program is terminated.

  On the other hand, when it is confirmed that the user involved in the application is a genuine user and does not correspond to the inappropriate person list, the user's decryption software ID or the like is referred to on the user information DB 614 of the user. While charging is recorded in the user information, the piece data DB 616 is searched to read piece data d corresponding to the software ID included in the application, and the user application is accepted together with the rental information included in the application data. A response to this effect is transmitted to the electronic device 620 via the communication line β (s34). Then, the processing of the piece data delivery interrupt program is terminated. Note that billing is performed in the same manner as in the fifth embodiment.

  When the electronic device 620 subsequently receives a notification that the user application is rejected via the communication line β (s7), the electronic device 620 displays and outputs an error message on the output unit 622 (s8).

  On the other hand, when piece data d and rental information are transmitted from the distribution management center 610 as a response to accept the user's application (a7), a predetermined flag is set, while piece data d and rental are set. Information is recorded in the above-mentioned registry for piece data in the memory unit 624 (s9). At the same time, the piece data transmission date and time is recorded in the memory unit 624 using the clock function of the computer. Then, the application software that has updated the menu list and acquired piece data d is displayed and output to the output unit 622 as being rented (s1).

  Thereafter, when an operation of installing the application software being rented is performed based on the menu list through the operation unit 623 (s2), the electronic device 620 reads piece data d related to the application software on the memory unit 624, and the piece data The decryption program of the application software on the memory unit 624 or the recording medium is executed and processed using the execution information included in d (s10). Thereby, the application software and the installer of the application software are decrypted. Then, the electronic device 620 processes the installer and installs application software in the memory unit 625 (s11). Thereby, the application software can be used. Note that the decryption program execution software program is terminated when the termination process is performed by the user.

The decryption program execution software has the same rental period management contents as in the fifth embodiment. In this rental period management, the difference between the piece data transmission date and time and the current date and time is obtained as an elapsed period from when the piece data d is transmitted, and if this has reached the rental period included in the rental information, the rental period The application software installed on the memory unit 624 as being outside is processed and uninstalled by the uninstaller attached to the application software, and a predetermined flag is turned down.

  In such an unauthorized use prevention system 600, the same effect as the unauthorized use prevention system 500 can be obtained, and the piece data d can be obtained simultaneously with the application software. Compared to the above, the user has the effect of improving usability.

  With respect to the unauthorized use prevention systems 500 and 600, a distribution unit that distributes application software via a communication line and an application software that can communicate with the distribution unit via a communication line and that is distributed from the distribution unit The distribution means records application software and an installer, which is a program necessary for installing the application software, at least in a state where the installer is encrypted. And a first database recorded in a state where the decryption program for decrypting the installer has previously lacked execution information necessary for executing the decryption program included in the header information, The second execution information recorded When a user inputs a request for downloading application software to an electronic device, the electronic device transmits the request to a distribution unit via a communication line, and the distribution unit applies the application software related to the request. The installer and the decryption program are transmitted to the electronic device via the communication line, and the electronic device records the application software or the like in the memory unit or the recording medium. On the other hand, the user inputs an application software application to the electronic device. Then, the electronic device transmits the application to the distribution unit via the communication line, and the distribution unit electronically transmits the execution information of the decryption program for decrypting the application software installer related to the application via the communication line. The electronic device sends the execution information to the memory unit. Any design modification as long as the decryption program on the memory unit or the recording medium is decrypted by using the execution information on the memory unit at the time of the installation operation and the installer on the memory unit or the recording medium is thereby decrypted You can go.

  Therefore, the distribution management centers 510 and 610 have one application software DB 511 and 611, but may have a plurality. In this case, different types of application software such as game application software in one DB and word processor application software in a second DB may be stored in each DB, or stored in each DB. The application software may be the same, and it may be possible to prevent access from being concentrated on one DB during congestion. The same applies to the piece data DBs 516 and 616. The distribution management centers 510 and 610 include the application software DBs 511 and 611 and the piece data DBs 516 and 616. However, the application software DBs 511 and 611 and the piece data DBs 516 and 616 are located in a location different from the distribution management centers 510 and 610. It is also possible to install. In this case, the distribution management centers 510 and 610 authenticate the user and then send the WEB addresses of the application software DBs 511 and 611 and the piece data DBs 516 and 616 to the electronic devices 520 and 620. The electronic devices 520 and 620 The application software DBs 511 and 611 and the piece data DBs 516 and 616 may be accessed to obtain the application software and piece data d.

  In addition, although application software, an installer, and a decryption program are recorded in the application software DBs 511 and 611, it is of course possible to record them with other information added. As other information, it is determined whether or not the decryption program execution software is installed in the user's electronic devices 520 and 620. If it is determined that the decryption program execution software is not installed, the distribution management centers 510 and 610 There are programs that automatically access HP. If this program is recorded, when the user tries to execute the application software obtained in advance in the electronic devices 520 and 620 (the state in which the decryption program execution software is not downloaded), the distribution management centers 510 and 610 The WEB address is read out, and based on this, the distribution management centers 510 and 610 are automatically accessed. Thereafter, the decryption program execution software can be obtained by the procedure described above.

  The content of the decryption program execution software is only an example, and any design modification may be performed as long as the same content can be realized. For example, by operating and inputting an icon indicating application software on the memory unit 524 or 624 or the recording medium displayed by the operation system or the like in conjunction with the operation system or the like, the distribution management centers 510 and 610 can apply to the distribution management centers 510 and 610 as applications for use. Can be sent. In addition, regarding the rental period management contents of the software, the elapsed period from the time when the application software is installed or the time when the application software is installed is obtained instead of the elapsed period from the time when the piece data d is received. Alternatively, when the elapsed period is reached, the application software stored in the memory unit 225 may be deleted instead of being uninstalled. However, if deleted, no data such as application software remains, so it is necessary to download the application software again. The user registration interrupt program, decryption program execution software download interrupt program, and piece data distribution interrupt program are merely examples, and any design modifications are possible as long as the same contents can be realized. You can go.

  It should be noted that the fifth and sixth embodiments can be redesigned to a system that prevents unauthorized use of application software distributed for a fee or free of charge instead of rental. Has the same merit as The decryption program execution software used in this case only needs to delete the processing when the distributed application software is outside the rental period. As for the electronic devices 520 and 620, the decryption program execution software may not be downloaded from the distribution management centers 510 and 610, but a CD or the like may be installed through a recording medium. Of course, a dedicated device can be used instead of a computer.
