Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for determining identification information, an information service method, and an information service system. More specifically, a unique identification of a recording medium recorded on a recorded data recording medium on which information is recorded by prepress, or a recordable data recording medium on which information can be added or rewritten, such as a CD-R or CD-RW. Information identification method, information service method that records the information on the identification information management side or refers to the recorded identification information list and authenticates the identification information to determine its validity And an information service system.
[0002]
[Prior art]
In a disc-shaped data recording medium such as a compact disc (CD) or a digital versatile disc (DVD) on which predetermined information is recorded in advance by prepress, the content recorded on these recording media is not illegally copied. In order to protect copyrighted works such as contents, measures have been taken. Already, compact discs with copy protection are being sold.
[0003]
In addition to such a recorded data recording medium, a write-once or rewritable data recording medium such as a CD-R or a CD-RW, for example, requires that a specific content (for example, Since the number of cases of downloading music data and the like is increasing, it is necessary to prevent unauthorized copying from the data recording medium in this case as well. As one of the countermeasures, it has been considered to record unique identification information on these recorded or recordable data recording media.
[0004]
In the case of a recorded data recording medium, after the information is recorded in the program area, identification information unique to each medium is recorded in a specific area, and in the case of a recordable data recording medium, the identification information is specified at a factory shipment stage. Area, the identification information unique to the medium is recorded. The specific area is an area from which information can be read but information cannot be written.
[0005]
[Problems to be solved by the invention]
By the way, in a case where identification information unique to each medium is recorded on a recorded data recording medium or a recordable data recording medium, in addition to using this identification information as an identifier for eliminating unauthorized copying, a specific , For example, can be used as an identifier when acquiring specific service information (service content) stored in a specific Web site.
[0006]
When it is intended to use the identification information as an identifier when acquiring such a special service, it is possible to set the condition for acquiring the specific service information unconditionally, but in a normal case, for example, It is conceivable to provide a conditional service in which service information can be obtained only for those who have purchased the data recording medium properly.
[0007]
In the case of providing a conditional service in this way, if the identifier used when accessing the specific service organization, that is, the identification information is the identification information given to the recording medium from which the medium was purchased legally, There is no particular problem, but instead, for example, it is conceivable that the identification information obtained when the information is illegally copied from the data recording medium is used. However, it is not rational to give specific service information to a person who has accessed using the identification information acquired illegally.
[0008]
To do so, it is necessary to accurately determine whether the identification information used to access the service information is the identification information recorded on a properly purchased data recording medium or the identification information obtained by means such as unauthorized copying. It is advisable to make a determination to provide specific service information according to the result. This is preferable from the viewpoint of protecting the copyrighted work.
[0009]
As a data recording medium, a DVD-R, a DVD-RW, or the like can be considered in addition to the above-described examples.
[0010]
Therefore, the present invention is to solve such a conventional problem, and determines whether the identification information recorded on the data recording medium is legitimate, and provides specific service information only to the correct answerer. The present invention proposes a method for determining identification information, an information service method, and an information service system.
[0011]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the identification information determination method according to the present invention described in claim 1, the identification information unique to the data recording medium recorded on the data recording medium is received, and the received identification information and And comparing the received identification information with the registered identification information to determine whether the received identification information is legitimate.
[0012]
A method for determining identification information according to the present invention described in claim 16 is a method for determining identification information on the side of reproducing a data recording medium on which identification information unique to a recording medium is recorded,
Receiving the identification information list from the site holding the identification information list, and performing authentication processing with the identification information read from the data recording medium based on the received identification information list;
When the read identification information is deemed to be valid identification information, a transition is made to a process of receiving information provided on the site based on the identification information.
[0013]
An information service method according to the present invention described in claim 30 is an information terminal device having a reproducing means for reading information from a data recording medium on which identification information unique to a recording medium is recorded; A management server that performs a service based on the information is connected via a communication network,
An information service method for providing service information based on the identification information transmitted from the information terminal device side to the information terminal device side,
Check the received identification information with reference to the identification information list registered on the management server side,
When the same identification information is present, the identification processing of the unauthorized identification information is performed,
Only when it is determined that the access is based on valid identification information, the processing shifts to the service information acquisition processing.
[0014]
An information service system according to claim 56, wherein the information service provides information stored on the management server of the identification information using the identification information unique to the medium recorded on the data recording medium. The system
Having an identification information reproducing device and an identification information management server connected by a communication network,
The identification information reproducing apparatus reproduces the data recording medium, stores the medium-specific identification information recorded on the data recording medium, transmits the identification information, and is provided from the management server side. Having transmission / reception means capable of receiving service information,
The identification information management server has a service information database storing a plurality of service information to be provided, and a management database.
On the identification information reproducing device side, reads the identification information from the data recording medium, transmits the read identification information to the identification information management server side via the communication line network,
On the identification information management server side, when providing the service information,
The received identification information is collated with reference to the registered identification information list, and when the same identification information is present, a process of determining unauthorized identification information is performed.
Only when it is determined that the access is based on valid identification information, the process shifts to information acquisition processing based on the identification information.
[0015]
The present invention is directed to a data recording medium on which identification information unique to the medium is recorded. At least identification information (UID) unique to the medium is recorded on the data recording medium, and the identification information UID includes information indicating the type of the recording medium. The identification information UID can further include additional information (related information) such as information indicating the type of service information that can be enjoyed by the recording medium and the number of times of service. The identification information UID is recorded in a specific area that can be reproduced but cannot be rewritten.
[0016]
By accessing the service organization, for example, a management server for identification information (for example, a Web site) using the identification information UID unique to the data recording medium, various service information stored in the management server is obtained. . The service information includes contents of various genres such as music, video, software, and the like.
[0017]
In order to obtain service information, it is confirmed whether the user associated with the accessed identification information UID is a regular purchaser of the data recording medium, and an information service system is provided that provides the service information only to the regular purchaser. I do. The identification information UID used at the time of access is used to determine whether or not the data recording medium is a regular purchaser.
[0018]
The management server uses the identification information (identification information database) obtained from the data recording medium manufacturer or the medium maker to determine the validity of the identification information, or accumulates the accessed identification information one by one. The determination is made using the stored identification information database. If the same identification information does not exist, the service information is provided assuming that the data recording medium is a regular purchaser.
[0019]
When the same identification information already exists, the above-described service information is provided only to the user of the identification information that has been regarded as a regular purchaser through a predetermined determination process. The predetermined discrimination processing is performed while discriminating whether the data recording medium from which the accessed identification information is read is a recorded data recording medium on which information is recorded by prepress and a recordable data recording medium such as a write-once type. Done.
[0020]
The following information can be considered as information used for the data recording medium determination processing. The first is to use the network address (such as an IP address) of the information terminal device used for access. If the network address is the same, it is accessed using the same information terminal device, so that it can be regarded as an authorized purchaser of the data recording medium. Even if the same identification information is accessed using a data recording medium such as an illegal copy, it is not considered that the same information terminal device as the authorized purchaser is used to access the management server side. It is.
[0021]
Second, there is a concept of using the access time interval for the discrimination information. This is because it is not normally considered that a regular purchaser accesses the management server again in a short period of time to obtain, for example, the same service information.
[0022]
Thirdly, the user uses registered identification information URID of the user. The user registration identification information URID is information different from the medium-specific identification information UID set for identifying the user himself. When the user registration identification information URID is the same from the same network address, the same user registration identification information URID is used. This is because even if it is the identification information UID, it is considered that the access is from the authorized purchaser of the data recording medium.
[0023]
If the first to third discrimination information can be used individually, two or more of the first to third discrimination information can be used in any combination, or if the first to third discrimination information is all used. Can also be used. In the case of using all of them, it can be more accurately determined whether or not the user is an authorized purchaser.
[0024]
As another discrimination process, whether the recording medium from which the identification information is finally read is a recorded data recording medium (ROM version) is determined by the unique information (specifically, recorded on the data recording medium). A wobble signal, an identification signal unique to a medium recorded in a lead-in area, and the like).
[0025]
For this purpose, first, when this data recording medium is read out when it is illegally copied to a recordable data recording medium, the identification information UIDb for the recordable data recording medium as identification information at that time is sent to the management server side. By transmitting the recordable data recording medium identification information UIDb in advance on the management server when transmitted, an unauthorized copy medium can be eliminated.
[0026]
If the identification information UID is not the recordable data recording medium identification information UIDb, the existence of the program memory area PMA is confirmed. If the program memory area PMA exists, the identification information from the illegally copied recordable data recording medium Can be determined.
[0027]
When there is no program memory area PMA, the determination is made based on information unique to the data recording medium already recorded on the recording medium. For example, when a wobble signal is used, it is determined whether or not it is a ROM version based on whether or not a wobble signal exists. Thus, when the identification information UIDb is not unique to the recordable data recording medium, the program memory area PMA is not present, and no wobble signal exists, it is determined that the identification information is from the illegally copied data recording medium. In addition, it is possible to reliably eliminate access from a data recording medium that has been illegally copied.
[0028]
In order to determine the wobble signal, for example, the presence or absence of a special signal (1, 0 modulation signal) superimposed on the wobble signal is detected, or the frequency component of the wobble signal is detected. Whether or not the signal is a wobble signal recorded on a recorded data recording medium can be determined based on the presence or absence of a specific signal or the presence or absence of a frequency component.
[0029]
The information service method proposes a method of executing the above-described various discrimination processes and providing specific service information only to the authorized purchaser of the data recording medium. The server side and the Internet, an information service network is constructed via a communication network such as an intranet, and the identification information unique to the data recording medium transmitted from the information terminal device is determined by using the above-described method. A system that can provide specific service information to a user can be constructed.
[0030]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of an identification information determination method, an information service method, and an information service system according to the present invention will be described in detail with reference to the drawings.
[0031]
FIG. 1 shows an embodiment of a disk-shaped data recording medium 10 which is a writable recording medium. The recording medium 10 has a main recording area 14 and auxiliary recording areas 16 and 18, and the main recording area 14 is an area where information can be written from an information terminal device (not shown). Is a writable data recording medium which is an area where the information terminal device cannot write.
[0032]
Medium information and the like are recorded in an area 18 belonging to the innermost circumference of the auxiliary recording areas 16 and 18, and original data (specific content) is recorded in the main recording area 14.
[0033]
Typical examples of the writable recording medium are a write-once CD-R and a rewritable CD-RW for a compact disk CD. Typical examples of the digital versatile disk DVD include a recordable DVD-R and a rewritable DVD-RW.
[0034]
As is well known, the optical disk 10 has a lead-out area 12 at the outermost periphery and a program area (PA) 14 as a content recording area inside the lead-out area 12. This program area 14 corresponds to a main recording area. A lead-in area 16 for recording TOC information is provided on the inner side of the program area 14, and a program memory area (PMA) 18 is provided on the inner side. The lead-in area 16 and the program memory area 18 correspond to an auxiliary recording area.
[0035]
As is well known, temporary TOC information before completion processing or finalization processing is recorded in the program memory area 18. While the temporary TOC information is recorded in the program memory area 18, contents can be written in the program area 14. However, when an operation to be completed is performed, the TOC information is written in the lead-in area 16, and subsequent writing (recording) processing cannot be performed.
[0036]
FIG. 2 shows an optical disc as a recorded data recording medium on which data is recorded in a pressing process. The optical disk 10 includes a program area 14 which is a main recording area in which data is recorded, a lead-out area 12 on the outer peripheral side, and a lead-in area 16 on the inner peripheral side. CD-ROM, DVD-ROM and the like are typical optical disks as the recorded recording medium.
[0037]
Medium information UID is recorded on the data recording medium 10 shown in FIG. 1 or FIG. The medium information UID is for acquiring the information (service content) stored in the management server after the authentication of the medium and the authentication when the specific management server is accessed. The data recording medium 10 can be used as a kind of service provided to a person who has purchased the data legally. In the case of a recordable data recording medium, the service information to be recorded on the medium can be downloaded after purchasing the medium. Can be used. Even a recordable data recording medium can be used as information for acquiring the service information described above.
[0038]
FIG. 3 records medium information (UID) unique to the data recording medium, whether it is a recorded medium or a recordable unrecorded medium. The medium information UID can include related information related to the medium in addition to the medium identification information unique to the medium. The embodiment in FIG. 3 is the latter example, and can also determine the type of the medium. This is when information is included.
[0039]
FIG. 3A is a specific example of the identification information UIDa recorded on the recorded data recording medium PPD on which information is recorded by prepress. The header information (PPD header) indicating the type of the medium and the identification information unique to the medium at the beginning constitute the medium identification information. Both the header information and the identification information unique to the medium use a serial number having a predetermined number of digits.
[0040]
Since the recording medium itself and its type can be identified by the medium identification information, the medium identification information is normally sufficient, but in this embodiment, additional information is added next to the serial number. The additional information includes the type of service information to be provided (the type of content), the number of services, and the key information for decrypting the information recorded on the recording medium when the information is encrypted. Requests can be considered. Finally, a code for error correction, for example, an ECC (Error Correcting Code) is added. The arrangement order of the information is not particularly limited.
[0041]
Such identification information UIDa is recorded in any one of the lead-in area, the lead-out area, and the program area. This is because any of these recording areas can be reproduced but cannot be rewritten. By recording the identification information UIDa in such an area, falsification of the identification information can be prevented. This identification information UIDa is recorded using a high-power laser or the like in a process after the original data is recorded. When the identification information UIDa is recorded, it is recorded as one of TOC (Table of Contents) information in the lead-in area as information indicating at which address the identification information UIDa is recorded.
[0042]
FIG. 3B shows a format of the identification information UIDb recorded on a write-once or rewritable data recording medium. Also in this case, the medium identification information includes header information (R / RW header) indicating the data recording medium and identification information unique to the medium. This medium identification information is also configured as a data string having a predetermined number of digits.
[0043]
Additional information is provided in addition to the medium identification information. The attached information is the same as that of FIG. 3A, and the following service forms can be considered. When the content to be recorded on the data recording medium is acquired from the management server and the acquired content is recorded on the data recording medium, what kind of content (music data, video data, software program data, etc.) Information indicating the type of download or the type of download can be added as a type of service form.
[0044]
Such identification information UIDb is recorded in the program memory area PMA. This is because the program memory area is an area where data can be reproduced but cannot be rewritten. When the identification information UIDb recorded in the program memory area is completed or finalized on the recording medium and the recording processing on the recording medium is completed, the laser is used together with the TOC (Table of Contents) information in the lead-in area using a laser. Recorded. The TOC information can be written as a part of the subcode information (specifically, Q channel information).
[0045]
The above-described identification information UID (UIDa, UIDb) is an example, and the number of items included in the identification information, the content of the items, and the type of content stored in the management server are arbitrary.
[0046]
When reproducing the data recording medium, a plurality of identification information UIDs are read out by referring to the TOC information in principle. The read identification information UID is stored, and is accessed at a necessary timing via a communication network (such as the Internet) to a management server (Web site) for identification information in this example, which is an information service organization.
[0047]
By transmitting the read identification information UID, the management server determines the content of the identification information UID recorded on the data recording medium, and the corresponding service information is transmitted to the user.
[0048]
The management server has an identification information management database in which a password (user registration identification information URID), which is identification information of the user, is managed, and the identification information UID is stored for each data recording medium accessed. Are stored as management information.
[0049]
In the information service system according to the present invention, as shown in FIG. 4, an information terminal device side 20 to receive a service and an identification information management server (Web site) 30 storing service contents are connected to a communication line such as the Internet. It is constructed by being connected via a network 40. Then, by transferring the identification information UID read by the information terminal device 20 to the management server 30 side, if the identification information UID is authenticated, the information is analyzed and stored in the management server 30 side. Provide corresponding services.
[0050]
The information terminal device 20 is provided with a disk reproducing unit (which may be a recording / reproducing unit) and a data transmitting / receiving unit. The information terminal device 20 can read and reproduce original data from the optical disk 10 as a data recording medium, and This is an apparatus for reading the identification information UID recorded in the storage device and receiving a specific service using the read identification information UID. Therefore, the optical disk 10 described below is an example of a recorded data recording medium such as a CD-ROM.
[0051]
FIG. 5 shows an embodiment of the information terminal device 20, which has the identification information reproducing device 50 functioning as a disk reproducing means for reproducing the optical disk 10 as described above. The information terminal device 20 includes a storage unit 23 for recording and storing various data, including a control unit 22 composed of a CPU for controlling the entire device, a storage unit 23 composed of a hard disk in this example, and data A data transmitting / receiving means (communication interface) 24 for exchanging data is connected to the bus 27. Further, a display unit 25 such as an LCD, and input means 26 such as a keyboard for inputting operation information are connected to each other via a bus.
[0052]
With this configuration, starting from a process of reproducing data including identification information from the optical disk 10, the identification information UID read from the optical disk 10 is transmitted to the management server 30 side, and a data exchange process with the outside for acquiring necessary information; Furthermore, storage processing of received data and the like are realized. The control unit 22 has a built-in memory means (not shown) such as a ROM in which processing programs necessary to realize these processes are stored.
[0053]
FIG. 6 shows an embodiment on the management server 30 side. The management server 30 is configured to authenticate the identification information UID from the user, to provide a service specified when authenticated, and to perform processing for media management and the like.
[0054]
Therefore, as shown in FIG. 6, the management server 30 includes a control unit 31 having a CPU for controlling the entire apparatus, a database 32 storing service contents, and various management information such as identification information UID and key information unique to the optical disc. An accumulated management database 33 is provided. In addition to these, a transmission / reception means (communication interface) 34 for exchanging data with the outside, a display unit 35 such as an LCD for displaying information such as identification information UID, and a keyboard and a mouse used for inputting information. It comprises input means 36 and the like. The control unit 31 has a built-in memory means (not shown) such as a ROM in which processing programs necessary to realize these processes are stored.
[0055]
FIG. 7 is a system diagram of a main part showing an embodiment of the identification information reproducing apparatus 50 according to the present invention.
[0056]
When the servo controller 52 is controlled by the control signal from the control unit 22, the spindle motor 54 rotates, and the optical disc 10 keeps the linear velocity constant, and the recording information from the optical disc 10 is transferred to the optical pickup unit 55. Read by. The read optical signal is supplied to a demodulator 57 via an RF amplifier 56 in a state converted into an electric signal inside the unit, and demodulation of information (EFM demodulation) is performed. The information recorded in the program area 14 of the demodulated output is further subjected to error correction processing and decoding processing in an error correction and decoding circuit 58 at a subsequent stage. After that, while being output as reproduction output information via the output processing unit 59, the decoded output is further supplied to the identification information extracting means 62, and the identification information UID recorded on the optical disc 10 is extracted and separated from the demodulated output. .
[0057]
On the other hand, the demodulated output subjected to the EFM demodulation is also supplied to the reading means 60 as the TOC information extracting means, and the TOC information is extracted and separated. The extracted and separated TOC information is supplied to the control unit 22, and the recording address of the identification information is extracted from the TOC information. Using this recording address, only the identification information UID is extracted and separated from the demodulated output supplied to the extracting means 62, and this is temporarily stored in a memory means (RAM) 63.
[0058]
The identification information UID of the memory means 63 is read in accordance with the input information from the input means 26, and the read identification information UID is transmitted to the management server 30 via the transmission / reception means (transmission / reception interface) 24 (see FIG. 5). Sent to the side.
[0059]
Although not shown, the output processing unit 59 has a decoding function. When the information recorded on the optical disk 10 is encrypted, the decryption process is performed using the key information provided from the management server 30 side. The key information is the decryption key itself, or in some cases, information for generating a legitimate decryption key using this key information, or key information matching the security of the information service system is provided.
[0060]
The original data (video data and the like) recorded on the optical disk 10 is supplied from the output processing unit 59 to the display unit 25 via the bus 27 to reproduce the video and the like, and output to the outside as necessary. You. When the demodulated output is music, although not shown, the demodulated output is supplied to an audio reproducing circuit to reproduce audio.
[0061]
Now, various processing examples when the information service system as shown in FIG. 4 is constructed will be described with reference to FIG. FIG. 8 is a schematic diagram (flow chart) for explaining the processing of the entire information service system.
[0062]
The identification information terminal device 20 reproduces the optical disk 10 and acquires the identification information UID. This identification information UID is stored in the memory means 63. The identification information UID can be displayed on the display unit 25 at the same time, or can be made unknown in consideration of safety.
[0063]
Next, the user performs an access process to the management server 30. At this time, in order to perform user authentication, the user transmits a password PW or the like which has been previously agreed with the management server 30. When the user is authenticated, menu information (service menu) handled by the server is transmitted from the management server 30, and the service menu is displayed on the user. When the user selects a submenu using the identification information UID, the submenu selection information is transmitted to the management server 30 side.
[0064]
On the management server 30 side, the received identification information UID is analyzed, and processing according to the analysis contents is executed. As a premise, the management server 30 performs an authentication process to determine whether the received identification information UID is legitimate identification information using the medium type information and the management information for each medium stored in the management database 33. Do. This is to eliminate access from a recording medium that has been illegally copied. In this case, the medium management information can use the medium-specific management information (the same information as the identification information) provided by the disk manufacturer or the disk vendor, or accumulate the identification information provided by the user each time to perform the identification. A database for information may be constructed. Especially when the recording medium is a writable recording medium, the identification information may be recorded on the medium provider side, or a random number obtained from a random number device prepared in the information terminal device 20 may be used as the identification information. It is possible to use it.
[0065]
The management server 30 determines whether the received identification information UID is the identification information acquired by the authorized purchaser. The determination process differs depending on the configuration of the management server 30.
[0066]
When the user is authenticated as an authorized purchaser, information according to the identification information is transmitted to the user. The information according to the identification information includes a type of service information, service information, key information, and the like. If the user can select a song or the like if the service content itself is music data, for example, song information or the like is also provided to the user side.
[0067]
When the received information is the key information, the information terminal device 20 stores the key information in the memory unit 63 and decodes the information recorded on the optical disk 10 using the key information. When the recorded information is music data, it is reproduced using this key information.
[0068]
When the recording medium loaded in the information terminal device 20 is a writable recording medium, the received information is information to be recorded on the recording medium. In this case, the information reproducing apparatus 50 shown in FIG. Thus, an information recording / reproducing device (not shown) is prepared, and information downloaded using this information recording / reproducing device is recorded. When the downloaded information is encrypted for security reasons, key information for decrypting the information is obtained at the same time.
[0069]
The number of services can be limited by managing access from the information terminal device 20 on the management server 30 side.
[0070]
Next, the processing procedure will be described in more detail with reference to FIG. In the embodiment illustrated in FIG. 9, the identification information UID is discriminated while the identification information UID provided by the user is accumulated one by one, thereby constructing the identification information database (identification information reference table). This is an example.
[0071]
For convenience of explanation, the description will first be made with reference to FIG. 9 from the management server 30 side. First, in a state of waiting for the acquisition of the identification information UID, when the user accesses and receives the identification information UID, the received identification information UID refers to the management database 33 described above, and the same identification information UID is obtained. The existence is confirmed (steps 71 and 72).
[0072]
When the same identification information UID does not exist, it is regarded as the first access to the management server 30, and the first access is regarded as the access from the authorized purchaser of the data recording medium, and the service providing process is performed. (Steps 72 and 74). This is because, for example, it is not usually considered that a person who has made an illegal copy accesses the management server 30 side earlier than a regular purchaser.
[0073]
In step 72, if the same identification information UID already exists as a result of the reference, a determination process is performed to determine whether the identification information belongs to an authorized purchaser or has been obtained illegally (step 80). As a result of the determination process described later, for example, if the validity flag is set when it is determined that the user is an authorized purchaser, if the validity flag is set, the access is regarded as valid (step 73), and the service is provided as described above. Processing is performed (step 74).
[0074]
On the other hand, when the valid flag is not set, that is, when the identification information UID is highly suspected to have been obtained illegally as a result of the determination processing, the invalid flag is set. Alternatively, a message for stopping the service is transmitted to the user, that is, the information terminal device 20 (step 75). The message for warning processing is a message indicating that, for example, only one service is permitted, but the second and subsequent services are prohibited, because it is determined that the identification information UID has a strong possibility of being obtained illegally. The service stop message is the identification information UID that is likely to have been illegally acquired. In this case, the message is that the service is not permitted at all.
[0075]
Thus, it is possible to realize an information service method that determines the identification information UID and provides a specific service only to the authorized purchaser of the data recording medium.
[0076]
FIG. 10 is a flowchart showing an example of the above-described processing for determining unauthorized identification information. When it is determined that the same identification information UID exists, first, the identification information UID is recorded on which type of data recording medium. It is determined whether the information is identification information (step 81). That is, it is determined whether the identification information UIDa for PPD recorded on the recorded data recording medium or the identification information UIDb for R / RW recorded on the recordable data recording medium.
[0077]
When the identification information UID registered in the management database 33 is the identification information UIDa for PPD and the received identification information UID is the identification information UIDb for R / RW, this is a recordable data recording medium. Since it can be determined that an unauthorized copy has been used, an unauthorized flag is set in that case (step 85).
[0078]
When the registered identification information UID is the identification information UIDa for PPD, it is determined whether or not the received identification information UID forms a data string conforming to the same format (regular format) as the identification information UIDa. Otherwise, for example, it is considered that the illegally copied one has been tampered with, and in this case, an illegal flag is set (steps 82 and 85).
[0079]
If the identification information UID has a regular format, the type of the recording medium on which the received identification information UID is recorded is determined (step 90). That is, it is determined whether or not the identification information UIDa is recorded on the recordable data recording medium. Therefore, in the present embodiment, attention is paid to the program memory area PMA existing only in the recordable data recording medium.
[0080]
If the program memory area PMA exists, it is determined that the access has been made by the identification information UIDa copied to the recordable data recording medium, and in this case, an illegal flag is set (steps 83 and 85). When the program memory area PMA does not exist, a valid flag is set so that a specific service can be provided (steps 83 and 84).
[0081]
The existence of the program memory area PMA can be confirmed by setting the identification information reproducing device 50 provided on the information terminal device 20 side to, for example, a reproducing mode and reading information from the program memory area PMA.
[0082]
Therefore, the process on the information terminal device 20 side is a process as shown in FIG. Since the reproduction process for the specific area is instructed from the management server 30 side, the standby state for the read instruction for the PMA area is entered (step 91). When the read instruction is issued, the identification information reproducing apparatus 50 is set to the reproduction mode, The PMA area is reproduced, and when reproduction information is present, an information presence flag is transmitted to the management server 30 side when reproduction information is not present (step 92).
[0083]
Thereafter, a message reception standby state is set (step 93). If the received information is not a message, processing for temporarily storing the received service information in the memory unit 63 is performed (step 94). If the received information is a message, a display to that effect is made on the display unit 25 (step 95). The display is a message for warning processing or a message for service interruption as described above.
[0084]
In FIG. 10, when the PMA area does not exist, it is determined that the medium is a recording medium for PPD. However, after aggressively determining whether the medium is for PPD, whether the medium is a recorded data recording medium is determined. By making a determination, the legitimate identification information UID can be confirmed.
[0085]
FIG. 12 is a flowchart showing an example. 12, if FIG. 12 is described from the beginning, when the identification information UID registered in the management database 33 is the identification information UIDa for PPD and the identification information UIDb for R / RW, the reception is performed. If the identification information UID obtained has the same format as the R / RW identification information UIDb, it can be determined that the information is illegally copied on a recordable data recording medium. It stands (steps 132 and 133).
[0086]
If the identification information UID received in step 132 is not the R / RW identification information UIDb, it is determined that the identification information UID is temporarily the PDD identification information UIDa. However, the data recording medium 10 on which the identification information UIDa is recorded is not always a data recording medium for PPD. It is also conceivable that the recordable data recording medium is a copy of the PDD identification information UIDa.
[0087]
Therefore, even if it is determined in step 132 that the data is not the identification information UIDb for R / RW, it is determined in next step 134 whether the data recording medium is a recording medium for R / RW. In this example, confirmation processing is performed to determine whether a PMA area exists.
[0088]
That is, a transmission / reception process as shown in FIG. 11 for confirming the PMA area is performed, and as a result, it is confirmed whether data can be read from the PMA area (step 135). When the data can be read, the recording medium is a recordable R / RW data recording medium, and in this case, a process of setting an invalid flag in step 133 is performed. By this process, the illegally copied R / RW data recording medium can be eliminated.
[0089]
If the presence of the PMA area is not confirmed in step 135, a transmission / reception process for detecting the ROM version is performed next to determine the presence or absence of the PPD data recording medium (step 136). Whether or not the data recording medium is the ROM version, that is, whether or not the data recording medium is a recorded data recording medium is determined by, for example, the presence or absence of a wobble signal corresponding to a wobble groove provided in the data recording medium itself.
[0090]
As the wobble signal, for example, a signal obtained by modulating a predetermined wobble signal with a key signal of “1” or “0” for decrypting a recorded cipher text can be used. Alternatively, when a wobble frequency dedicated to the CD-ROM is formed using a wobble frequency different from the wobble frequency employed in the R / RW data recording medium, the wobble signal itself is used to perform detection. It is possible to determine whether or not it is a ROM version based on the frequency component thus obtained. By detecting the frequency of the wobble signal or a specific signal included in the wobble frequency, it can be determined whether or not the ROM version is used.
[0091]
Therefore, in step 136, the identification information reproducing device 50 is set to the reproducing mode, and an instruction to detect the wobble signal is issued. When a specific wobble signal cannot be detected, it is considered that the data recording medium has recorded the identification information UID by performing some illegal processing, and in this case, the process proceeds to step 133 to perform the illegal flag processing. . On the other hand, if a wobble signal is detected, it is determined that the information is reproduction identification information from a data recording medium (a PPD data recording medium) that has been purchased regularly, and a process of setting a valid flag is performed (step 138). .
[0092]
In FIG. 12, a wobble signal is used as a signal unique to a recorded data recording medium. However, for example, an identification signal unique to a medium recorded in a lead-in area may be used.
[0093]
As described above, by performing the processing of FIGS. 9 to 11 or the processing of FIGS. 9, 11 and 12, the data recording medium recorded particularly in the management table stored in the database 33 of the management server 30 side. In the case where the identification information UIDa is registered and the same identification information as the identification information UIDa is received, it is determined whether or not the identification information is genuine and the type of the recording medium on which this is recorded is determined. By doing so, it is possible to select only authorized purchasers and provide specific service information.
[0094]
In the example of FIG. 9, the process of determining the identification information received on the management server 30 side is executed using the management table for the identification information. As a pre-process of transmitting the identification information UID to the 30 side, a process of determining the identification information may be performed.
[0095]
FIG. 13 shows an embodiment of the present invention, in which the management server 30 is accessed to request transmission of identification information (UID list) registered in the management table for user authentication (steps 101 and 102). When the UID list is received, the UID list is temporarily stored in the memory means 63 (steps 103 and 104). Then, referring to this UID list, authentication processing is performed with the identification information UID to be used for transmission (step 105).
[0096]
The authentication process basically performs a process similar to the fraudulent UID discrimination process shown in FIG. 9, FIG. 10 or FIG. 12, and determines whether the identification information UID to be used for transmission is that of a regular purchaser or a fraudulent copy. It is determined whether or not it has been acquired. The process of determining whether the recording medium from which the identification information UID has been read is a recordable data recording medium based on the presence or absence of the program memory area PMA is performed in the same manner. Therefore, in this case, the determination process is executed only on the information terminal device 20 side without going through the management server 30.
[0097]
When the read identification information UID belongs to the authorized purchaser, the management server 30 is requested to provide predetermined service information (steps 106 and 107). When it is determined that the identification information UID is invalid, A message transmission request is made to the management server 30 and the system enters a standby state (steps 106 and 108). When the message is received, its contents are displayed (steps 109 and 110). The message content is the same as in the example described above. The message can be prepared in advance in, for example, the memory unit 63 of the information terminal device 20.
[0098]
With this configuration, the information terminal device 20 can easily determine whether the identification information is genuine, so that the burden on the management server 30 can be reduced accordingly.
[0099]
In the embodiment described above, the unique identification information UIDa recorded on the recorded recording medium is registered in the database 33 prepared on the management server 30 side, and transmitted using the identification information UIDa. Alternatively, the processing example of determining the identification information to be transmitted has been described. If information other than the identification information is used, the identification information can be determined more accurately.
[0100]
As information to be used in addition to the identification information, a network address (IP address) used when accessing the management server 30 from the information terminal device 20, an access time interval from the previous time, and user-specific identification information can be considered. Any one of these pieces of information or a combination of two or more pieces of arbitrary information is used. The embodiment shown in FIG. 14 is a case where the authenticity of the identification information is determined by using all of the above-described information.
[0101]
First, the identification information UID read from the data recording medium is received (step 121). Next, it is checked whether or not the same identification information exists by referring to the management database 33 (step 122). If the same identification information does not exist, the identification information is registered in the database 33 (step 123).
[0102]
When the same identification information UID does not exist, it is regarded as the first access to the management server 30, and the first access is regarded as the access from the authorized purchaser of the data recording medium, and the service providing process is performed. (Step 124). This is because, for example, it is not usually considered that a person who has made an illegal copy accesses the management server 30 side earlier than a regular purchaser.
[0103]
In step 122, if the same identification information UID already exists as a result of the reference, the network address used by the information terminal device 20 is checked next (step 125). The network address is a unique address given to a computer constituting the information terminal device 20. If the network address does not exist, it is determined that the access using the identification information UID is the first, and the network address is registered in the database 33 in association with the above-mentioned identification information UID. Alternatively, the selected service is provided (steps 123 and 124).
[0104]
If the identification information UID is the same but the network address is different, the access time interval from the previous time is determined (step 126). It is not normally conceivable that a regular purchaser of a data recording medium accesses the same Web site to obtain information. On the other hand, since the unauthorized copyr or the like wants to obtain the service information as soon as possible, it is determined whether or not the access timings are distant to a proper extent. When the access time interval is determined based on the number of days N, the number of days N is set in advance. For example, four to five days or more are determined.
[0105]
If the access time interval has passed N days or more, it is determined that the access is from a regular purchaser, and predetermined service information is provided (steps 126 and 124). This is because it is considered that the authorized purchaser does not always access using the same personal computer, but accesses the management server 30 using another information terminal device while carrying only the data recording medium. If the access is made within N days or less, identification information (user ID) unique to the user is determined (step 127).
[0106]
When the user ID is not registered in the database 33, the user ID is registered in the database 33 in the same manner as the network address in association with the identification information UID, and a service is provided (steps 128 and 124). This is because, even when the management server 30 is accessed using another information terminal device as described above, a case where the user ID has not been registered may be considered.
[0107]
When the user ID is registered in the database 33, it is checked whether the user ID is registered in the same identification information UID column (step 129). The service is provided (steps 129 and 124). However, if the received ID is different from the user ID registered in the column of the identification information UID, it should be determined that the access is made by an unauthorized copyr rather than by a regular purchaser. Alternatively, a service stop message is transmitted, and the determination process ends (step 130).
[0108]
By using the discrimination processing shown in FIG. 14, even if the authorized buyer accesses at a different time and place in steps 122, 125, and 126, it can be regarded as an authorized buyer. Whether or not can be further sieved. As a result, even when the identification information is the same as the identification information UIDa, the pirated recording medium or the illegally copied recording medium can be excluded by determining the user ID.
[0109]
It should be noted that when the prepressed information is copied to a recordable data recording medium that does not have the medium-specific identification information itself, It is considered that the identification information on the prepress side is copied as it is. When the management server 30 is accessed using the identification information read from such a recordable data recording medium, at least the user ID at that time does not match that of the authorized purchaser. Even when the identification information is read out of the data recording medium, the data recording medium can be excluded as being illegally copied.
[0110]
Now, in order to record the above-mentioned identification information UID (UIDb) on a recordable data recording medium, it is necessary to use a normal light source (laser light source) in the PMA area 18 and record it as a part of the above-mentioned TOC information. it can. Then, by performing the complete processing or the finalize processing, it is possible to record the TOC information in the lead-in area 16. The PMA area 18 for recording as a part of the TOC information is an area where data cannot be recorded by the user himself, but can be reproduced.
[0111]
Further, in the present invention, the above-described identification information UIDa can be recorded and used on the data recording medium on which the press-worked data is recorded as shown in FIG. In this case, identification information UID (UIDa) is recorded on the master disk on which desired data is written, for example, using a high-power laser. The identification information UIDa is recorded in one of the lead-in area, the lead-out area, and the program area. An example of the recording method will be described with reference to FIG.

It is assumed that the semi-finished optical disc 340 represents an optical disc in which information data has been recorded as described above, but additional recording information has not yet been recorded.
[0119]

The additional recording control means 220 calculates an area in which the additional information 420 is to be recorded based on the additional information 410 or the modulation signal data pattern, and performs control for additionally writing the additional information 420 stored in the scale means in this area.
[0121]
The write-once means 230 is equipped with a high-power laser (not shown), and in accordance with the write-once control means 220, writes the write-once information 420, which is identification information unique to the optical disc, stored in the memory means on the semi-finished optical disc 340 at high output. Recording is performed using a laser, and an optical disc 350 of a product on which the additional information 420 is recorded is generated. The optical disc 350 indicates the data recording medium 10 on which the above-described identification information UID is recorded.
[0122]
In the write-once apparatus 200, the write-once related information 410 used by the modulation signal transmission apparatus 140 or the modulation signal data pattern is stored in the modulation information storage means 170 in advance. The additional recording control unit 220 calculates an area for recording the additional information 420 based on the additional recording related information 410 or the modulation signal data pattern, and controls the additional recording unit 230 to additionally record the additional information 420 in this area. The additional recording means 230 records the additional recording information 420 on the semi-finished optical disc 340 according to the additional recording control means 220, and manufactures the product optical disc 350.

As a write-once information recording method, a modulation signal transmission device generates a modulation signal having a non-modulation interval in an arbitrary interval of a modulation signal when modulating information data, manufactures a semi-finished optical disc, and uses the non-modulation interval in the write-once recording device. There is a method of recording additional information and manufacturing an optical disk of a product.
[0124]
FIG. 16 shows an example. The modulation signal transmitting apparatus 140 acquires information on the non-modulation section to be inserted into a modulation signal data pattern (hereinafter, referred to as an EFM data pattern) from the additional recording related information 410. Where the non-modulation section is inserted or how many non-modulation sections are inserted in the EFM data pattern is arbitrary and is not specified. However, it is set so that the semi-finished optical disc 340 into which the non-modulation section is inserted can perform tracking servo, that is, the continuous non-modulation section is equal to or less than the tracking servo band. This tracking method is not particularly limited. In the example of FIG. 15, the sub-coding section is a non-modulation section. The non-modulation section can be provided at an arbitrary position in the sub-coding section excluding the synchronization pattern and the data section into which the information data is inserted. Further, a plurality of non-modulation sections may be provided at certain fixed intervals or at random intervals.
[0125]
The modulation information generating means 160 generates a modulation signal (hereinafter, referred to as an EFM signal) in which a non-modulation section is provided in a part of the EFM data pattern according to the additional recording related information 410 and outputs the signal to the laser beam recorder 600. I do. The waveform of the EFM signal output to the laser beam recorder 600, that is, the waveform of the EFM signal recorded on the optical disk master 320 has a signal level of 0 in the sub-coding unit. The semi-finished optical disc 340 manufactured according to this does not have pits in the sub-coding part which is a non-modulation section.
