Abstract

<P>PROBLEM TO BE SOLVED: To copy or move data with copy or move restriction recorded in a medium without updating information recorded on the medium. <P>SOLUTION: In copying the data from the medium 108 which records data with the copy restriction set, and right information including identification information and copy restriction information on the data, the copy restriction information on the data stored in a nonvolatile memory (an information storage means) 111 is compared with the copy restriction information on the data read from the medium, to determine whether the data can be copied. When the data is copied, the copy restriction information is updated and rewritten into the nonvolatile memory. When the data information is not stored in the nonvolatile memory such as the case of regenerating the data for the first time, the copy restriction information read from the medium is stored in the nonvolatile memory. As to the data with move restriction set, move processing is carried out in the same way. <P>COPYRIGHT: (C)2004,JPO

Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to copy processing of copyrighted content such as audio data and video data (copy processing of data which is read from a recording medium and output to the outside without deleting the content stored in the recording medium). And a function of performing a content move process (a process of reading data from a recording medium and outputting the content to the outside, and a process of moving data for deleting the content stored in the recording medium). In addition, the present invention relates to a data copy and move processing method, and more particularly to a data copy and move processing apparatus for copying or moving data (copy-limited data or move-limited data) for which copy restrictions or move restrictions are set, and data copy and move. Regarding the processing method.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, when distributing copyrighted audio data or video data (also called content), the content is recorded on a storage medium (also called package media) such as a CD, DVD, or video cassette and sold or sold. Had been transferred. In this case, the purchaser of the package medium (recording medium) is not restricted in reproducing the purchased content at an appropriate price.
[0003]
However, in recent years, transmission paths such as the Internet have developed, and data has been distributed (also referred to as distribution) via such transmission paths regardless of package media. In data distribution using the Internet or the like, compressed audio data and video data are mainly used, and data can be distributed within a reasonable time even on a relatively narrow band transmission path. In many systems of such data distribution, data is stored in a server of a distribution source, and data is distributed on demand according to a user's request, and settlement (charging) of data is performed at the time of distribution or viewing. Is
[0004]
In the case of data distribution using conventional packaged media, buyers are more likely to purchase media and incidental materials (cases, jackets, booklets, etc.) at an appropriate price, rather than purchasing data and rights. In the viewing, it is considered that copying is infinitely compensated indefinitely. On the other hand, in the case of data distribution using the Internet or the like, there is no package as a so-called substance, and only data and rights are distributed to buyers, who pay for the rights related to the content. It becomes the image. Therefore, there is an environment in which "restricted distribution", in which the right to use the content is restricted and the price is reduced (or made free), is accepted by the user.
[0005]
Here, the restricted use rights mainly include restrictions on reproduction (hereinafter, reproduction restriction), restrictions on copying (hereinafter, copy restriction), and restrictions on move (move restriction). As the reproduction restrictions for restricting the reproduction of data, for example, the following reproduction restrictions, restrictions on the number of times of reproduction, restrictions on the cumulative time of reproduction, restrictions on the reproduction date, and the like. There are a plurality of types of move restrictions, such as a move permission restriction, a move frequency restriction, and a move date restriction, for example, as described below, such as a restriction, a copy number restriction, and a copy date restriction.
[0006]
1. Restrictions on permission to play
Reproduction permission restriction means that data is recorded on media in advance by the data distribution side (when data is recorded on package media), or when data is recorded on media by the user (such as the Internet). , And data is recorded on a medium by a user), the reproduction of the data is prohibited until the data distribution side or the like receives the reproduction permission of the data. There are several methods for obtaining a data reproduction permission (that is, releasing the data reproduction permission restriction).
-A method of receiving a reproduction license by paying a fee (charging).
-A method of obtaining a reproduction license by obtaining a password for data reproduction, etc., instead of a fee.
[0007]
2. Play count limit
The restriction on the number of times of reproduction indicates that the number of times of reproduction of data is restricted. By this restriction on the number of times of reproduction, for example, it is possible to restrict the number of times of reproduction to allow only five reproductions. In addition, for example, it is necessary to preliminarily define a ratio (for example, 50% or the like) to the total reproduction time of the data and a case where the reproduction number is counted as one once. is there.
[0008]
3. Cumulative playback time limit
The term "reproduction cumulative time limit" refers to limiting the cumulative time for reproducing all or a part of the data. With the limitation on the cumulative reproduction time, for example, it is possible to restrict the cumulative reproduction time in such a manner that only 15 minutes of the data can be reproduced.
[0009]
4. Reproduction date limit (with expiration date or expiration date)
Reproduction date restriction means that reproduction is permitted up to a predetermined date (reproduction expiration date or expiration date), and subsequent reproduction is prohibited. By this reproduction date restriction, for example, it is possible to restrict the reproduction date in such a manner that only reproduction until September 30, 200X is possible. The reproduction date limit also includes a case where reproduction is permitted only for a predetermined number of days (months, weeks, etc.) from the purchase date and time and the date and time when reproduction was first performed, and reproduction after that is prohibited. Shall be. Thereby, for example, it is possible to set a reproduction limit of 30 days for data purchased on September 1, 200X, and to limit data reproduction to September 30, 200X.
[0010]
5. Copy permission restrictions
The copy permission restriction means that the data is recorded on the medium in advance by the data distribution side (when the data is recorded on the package medium), or the data is recorded on the medium by the user side (such as the Internet). , And data is recorded on a medium by the user), the copying of the data is prohibited until the data distribution side or the like obtains a data copy permission. As a method of receiving the data copy permission (that is, releasing the data copy permission restriction), there are several methods similar to the reproduction permission restriction.
-A method of receiving a copy permission by paying a fee (charging).
-A method of obtaining a copy permission by obtaining a password for copying data, etc. instead of the price.
[0011]
6. Copy count limit
The copy number limitation refers to limiting the number of data copies. By this copy number limitation, for example, it is possible to limit the number of copies that can be performed only five times. If the copy process has not been performed (for example, if the data to be copied has not been completely output to the outside), the number of copies is not reduced (or the number of copies once reduced is reduced to the original value). Can be returned).
[0012]
7. Copy date limit (with copy expiration date or expiration date)
The copy date limit indicates that copying is permitted up to a predetermined date (copy expiration date or expiration date), and subsequent copying is prohibited. By this copy date restriction, for example, it is possible to limit the copy date that can be copied only until September 30, 200X. The copy date restriction also includes a case where copying is permitted only for a predetermined number of days (such as the number of months or weeks) from the purchase date and time or the date and time when reproduction was first performed, and copying after that is prohibited. Shall be. Thus, for example, it is possible to set a copy expiration date of 30 days for data purchased on September 1, 200X, and to limit data copying until September 30, 200X. Conversely, it is also possible to prohibit copying until a predetermined date and permit subsequent copying.
[0013]
8. Move permission restrictions
The move permission restriction means that the data is recorded on the medium by the data distribution side in advance (when the data is recorded on the package medium), or the data is recorded on the medium by the user (such as the Internet). , And data is recorded on the medium by the user side), the move of the data is prohibited until the move permission of the data is received from the data distribution side or the like. As a method of receiving a move permission for data (that is, releasing the move permission restriction), the same method as the above-described copy permission restriction can be used.
[0014]
9. Move limit
The move count restriction refers to limiting the number of data moves. With the limitation of the number of moves, for example, it is possible to limit the number of moves that can be performed only five times. If the move processing has not been performed (for example, data to be copied has not been completely output to the outside), the number of copies is not reduced (or the number of copies once reduced is reduced to the original value). Can be returned). In addition, the number of moves can be set, for example, for a content (restricting the number of moves of a predetermined content), or set for a recording medium on which the content is recorded (a predetermined number of times). It is also possible to limit the number of moves that can be made from the recording medium.
[0015]
10. Move date limit (with move or expiration date)
The move date limit refers to permitting a move up to a predetermined date (move expiration date or expiration date) and prohibiting subsequent moves. By this move date limit, for example, it is possible to limit the date on which the move can be performed only by the move until September 30, 200X. Also, the move date limit includes a case where a move is permitted only for a predetermined number of days (such as a number of months or weeks) from the purchase date and time and the date and time of the first playback, and the move after that is prohibited. Shall be. Thus, for example, it is possible to set a 30-day move expiration date for data purchased on September 1, 200X, and to limit data move until September 30, 200X. Conversely, it is also possible to prohibit a move until a predetermined date and permit a move thereafter.
[0016]
When data is distributed or sent, information (right information: Usage Rule) that manages the above-described reproduction restrictions, copy restrictions, and move restrictions is also distributed or transmitted together with the data. Further, when data is recorded on a medium, right information on the data is also recorded on the medium at the same time. Thus, when reproducing, copying, or moving data, it is possible to simultaneously read out the right information related to the data and determine whether the data can be reproduced, copied, or moved.
[0017]
Among the above 10 types of reproduction restrictions, copy restrictions, and move restrictions, regarding the reproduction permission restriction, the reproduction number restriction, the reproduction cumulative time restriction, the copy permission restriction, the copy number restriction, the move permission restriction, and the move number restriction, data reproduction is described. When copying, moving, and the like, it is necessary to rewrite the right information itself and information related thereto. That is, for example, regarding the reproduction permission restriction, the copy permission restriction, and the move permission restriction, it is necessary to record that the reproduction permission, the copy permission, the move permission, and the like have been received, as right information. With regard to the limitation of the number of moves and the limitation of the cumulative reproduction time, it is necessary to subtract the remaining number of reproductions, the number of remaining copies, the number of remaining moves and the subtraction of the remaining cumulative time by performing the data reproduction, copying and moving. On the other hand, with regard to the playback date limit, copy date limit, and move date limit, it is determined whether or not playback is possible only by comparing the date of the calendar in the data copy and move device with the playback time limit before starting the data playback. It is not necessary to determine and update the right information at the time of reproduction, copy, and move.
[0018]
When performing the above-mentioned reproduction-restricted data, copy-restricted data, and move-restricted data in reproduction, copying, and moving, particularly when acquiring data via the Internet or the like, reception and recording of data on the user side. , Reproduction, copy, move, etc., can all be performed by the same PC (Personal Computer). The PC is a recording / reproducing apparatus having a storage medium such as a hard disk drive (HDD) inside the PC, and a real-time clock capable of measuring time even when the power is off (hereinafter referred to as a calendar clock). Theoretically, it is possible to perform processing with respect to any of the above restrictions 1 to 10. It should be noted that the present specification deals mainly with processing relating to copy restrictions (4 to 7 above) and move restrictions (8 to 10 above).
[0019]
Next, conventional copy processing of data with copy restriction and move processing of data with move restriction will be described. FIG. 6 is a block diagram showing an example of a conventional data copy and move processing apparatus for copy or move-limited data. In the data copy and move processing apparatus shown in FIG. 6, each functional block is illustrated as an individual unit. However, the data copy and move processing apparatus may be realized by a unit integrating the functions of a plurality of blocks. It is possible. As described above, the data copy and move processing device shown in FIG. 6 can be realized by a PC.
[0020]
The data copy operation or the move operation is started by an instruction from the user via the user interface unit 701. First, the medium writing / reading unit 707 reads, from the medium (recording medium) 708, the formatting right information related to the data copied or moved by the user. The formatting right information read from the medium 708 is decrypted by the copyright protection system encryption / decryption unit 706 as necessary, and the format is released by the formatter / deformatter 705. . The rights information obtained in this way is sent from the formatter / deformatter 705 to the main control unit / main memory 704, where the rights information is analyzed by the main control unit / main memory 704 to permit data copy or move. It is determined whether to do so.
[0021]
At this time, for example, if the following conditions are satisfied, copying or moving of the data is permitted.
-When copying is already permitted for data with copy permission restriction, or when a new copy permission is obtained at the start of data copy.
-When the count value of the number of remaining copies is not zero for data with a limited number of copies.
-When the move is already permitted in the data with restricted move permission, or when a new move permission is obtained at the start of data move.
-When the count value of the remaining number of moves is not zero for data with a limited number of moves.
[0022]
If the above conditions are not satisfied, copying or moving of the data is not permitted, and a message such as "copy (move) is not permitted" is displayed, and the copying operation or the moving operation is terminated. . On the other hand, when copying or moving is permitted, predetermined formatted data is read from the medium 708, and decrypted by the copyright protection encryption / decryption unit 706 if necessary, The format is released by the deformatter 705. The data thus obtained is sent from the formatter / deformatter 705 to the right information separating / combining unit 703 and combined with the right information and the like, and further sent to the data receiver / transmitter 702 to output data to the outside. Is done. Data output from the data receiver / transmitter 702 is received by an externally connected data recording device or the like, and is stored in a predetermined recording medium by being written in a predetermined recording medium. When the data move process is performed, the medium writing / reading unit (information deleting unit) 707 deletes the moved data from the recording medium.
[0023]
Next, when the data output is completed, for example, the rights information is updated as described below, and the updated rights information is written to the medium 708, thereby completing all the processes.
For data with copy permission restriction, if a new copy permission is obtained at the start of copying this data, the data is updated to the right information indicating that the copy has been permitted.
For data with copy number restriction, the count value of the remaining copy number recorded in the right information is decremented by one.
For data with restricted move permission, if a move permission is newly obtained at the start of the move of the data, the data is updated to the right information indicating that the move has been permitted.
In the data with the limited number of moves, the count value of the remaining number of moves recorded in the right information is reduced by one.
[0024]
Further, as techniques for managing reproduction, copying, and moving of a file, for example, the following Patent Documents 1 and 2 and Non-Patent Document 1 are known. Patent Literature 1 discloses a playback restriction technique for decrementing the value of the remaining number of times of reproduction when a predetermined time has elapsed during the reproduction of an audio data file having the number of times of reproduction restriction. Patent Document 2 discloses a technique for storing time information when a content is copied (copied), and performing duplication management using the time information when the content is copied. Non-Patent Document 1 discloses a technique related to management of various files, such as copying, moving, and checking in / out of files.

[Problems to be solved by the invention]
However, when copying or moving data for which a copy permission limit, a copy count limit, a move permission limit, or a move count limit is set, the rights information on the data to be copied or moved is updated and the rights information in the media is updated. Will always be rewritten.
[0027]
Further, as a disk in which contents (data) are recorded in advance, such as a package medium, for example, a ROM type (writable) pre-recorded disk is mainly used. When the right information is recorded in the location, it is impossible to copy the right information by the data copy and move processing device.
[0028]
In addition, by obtaining a copy permission or a move permission each time a copy or move is performed by the data copy and move processing device, the data copy on which data on the media cannot be rewritten and the copy permission restricted data by the move processing device can be obtained. Copy processing or move processing of data with restricted move permission is possible, but it is very troublesome work for the user, and the data distribution side also has trouble managing the charge related to copy permission or move permission. There is a problem.

The user interface unit 101, data receiver / transmitter 102, main control unit / main memory 104, and data reproduction unit 109 shown in FIG. 1 are the same as the conventional data copy and move processing device shown in FIG. Also, like the data copy and move processing device shown in FIG. 6, each functional block is shown as an individual unit, but the data copy and move processing device can be realized by a unit integrating the functions of a plurality of blocks. It is also possible to realize by a PC.
[0044]
The media (recording medium) 108 records contents such as audio data and video data and right information. The rights information also includes a unique ID of each content, a copy restriction (copy permission restriction, copy number restriction, etc.) and a move restriction (move permission restriction, move number restriction, etc.) set for each content. . The unique ID is an identifier (identification information) unique to the data and includes, for example, country information, copyright holder information (recording company name, etc.), creation date, data identification information, sub information, and the like. obtain. In the present invention, it is preferable that, in addition to the identification information (such as a song title in the case of audio data) being set for each data, unique sub-information (such as a distribution ID) for each piece of distribution data is set. Further, it is also possible to generate sub-information corresponding to each data at the time of recording on the medium 108 and add it to the unique ID of each data. Conventionally, a unique ID may be added to data and supplied, and the unique ID may be included in the right information and recorded on the medium 108. However, conventionally, the unique ID is used for copy restriction and move restriction. Clarify that it is not used for management. According to the present invention, when managing the copy restriction and the move restriction, the data is identified using the unique ID set for each data, so that permission or denial of the copy or move is given to the erroneous data. There is no.
[0045]
The data copy / move processing device shown in FIG. 1 includes a memory writing / reading unit 110. The memory writing / reading unit 110 reads data from a nonvolatile memory (information storage unit) 111 different from the medium 108 and writes data to the memory. The non-volatile memory 111 is, for example, a type of semiconductor memory, and can electrically record information, read information, and erase information, and retains its stored contents even when the power is turned off. . The nonvolatile memory 111 is called a flash memory.
[0046]
Next, a process for copying and moving data recorded on the medium 108 will be described. FIG. 2 is a flowchart for explaining copy processing and move processing of data recorded on a medium in the present invention. The flowchart shown in FIG. 2 is a process common to the following first and second embodiments.
[0047]
The copy operation or the move operation is started by an instruction from the user via the user interface unit 101. First, in step S201, the medium writing / reading unit 107 reads, from the medium 108, formatting rights information relating to data instructed to be copied by the user, and if necessary, reads the read formatting rights information. The data is decrypted by the copyright protection encryption / decryption unit 106, and the format is released by the formatter / deformatter 105. The rights information thus obtained is sent from the formatter / deformatter 105 to the main control unit / main memory 104.
[0048]
On the other hand, in the non-volatile memory 111, information in which a unique ID relating to data recorded in advance on the medium 108 and rules such as copy restrictions and move restrictions are described (hereinafter collectively referred to as management information or a management information table) And have been saved. In step S202, the memory writing / reading unit 110 reads the management information table from the nonvolatile memory 111, and the read management information table is sent from the memory writing / reading unit 110 to the main control unit / main memory 104. Note that the management information table is read from the nonvolatile memory 111 and sent to the main control unit / main memory 104 immediately after the power of the data copy and move processing device is turned on, not at the start of individual data copy or move. It may be.
[0049]
FIG. 3 is a diagram schematically illustrating an example of the management information table used in the present invention. The management information table records a unique ID (identification information unique to each data) of data that has been copied or moved, and copy restriction information corresponding to each data. In FIG. 3, the copy restriction information includes, for example, copy permission restriction information and copy number restriction information corresponding to each data, and the move restriction information includes, for example, move permission restriction information and move number restriction information corresponding to each data. Is illustrated, and copy permission restriction information and copy number restriction information will be described in the first embodiment, and move permission restriction information and move number restriction information will be described in the second embodiment. To
[0050]
As described above, the unique ID is a unique identifier capable of identifying each data, and FIG. 3 illustrates a mode in which the unique ID is configured by a combination of English characters, symbols, numbers, and the like. On the other hand, as the copy permission restriction information or the move permission restriction information, information indicating whether copy or move is permitted is recorded. FIG. 3 illustrates a mode in which, when copying or moving is permitted, an encryption key (decryption key) necessary for copying or moving the data is recorded. It is also possible to record information other than the encryption key, such as a value indicating whether or not the encryption key has been granted (1: granted, 0: not granted). In addition, "no information" is recorded in the copy permission restriction information or the move permission restriction information relating to the data for which the copy or move permission restriction is not set (particularly, the data for which the copy or move number restriction is set). It is preferable to keep it.
[0051]
Note that the content and format shown in FIG. 3 are merely examples, and the format of the unique ID and the format and number of digits of other information can be set arbitrarily. Further, each information in the management information table and the management information table itself may be encrypted and recorded in the nonvolatile memory 111 so that each information in the management information table is not easily read. .
[0052]
The main control unit / main memory 104 performs the following processing using the right information received from the formatter / deformatter 105 and the management information table received from the memory writing / reading unit 110. First, in step S203, the main control unit / main memory 104 refers to the right information and determines the type of copy restriction or move restriction of data to be copied or moved (contents for which a copy or move instruction has been received from the user). Judge. That is, in the case of copy processing, it is determined whether the data is data with copy permission restriction or data with copy count restriction. In the case of move processing, whether the data is data with move permission restriction or data with move count restriction is determined. Judge. If there is no copy restriction or move restriction, copy or move can be performed as it is, and in the case of data with copy or move date restriction, it is built in the data copy and move processing device. By referring to the date and time by a time measuring means or the like, it is determined whether data can be copied or moved. The above operations are operations common to the following first and second embodiments, and these operations will be referred to as “common processing blocks”.
[0053]
<First embodiment>
Hereinafter, a first embodiment of processing relating to copying of data with copy permission restriction recorded on the medium 108 and processing relating to moving of data with restriction of move permission according to the present invention will be described. FIG. 4 is a flowchart illustrating a copy process of data with copy permission restriction and a move process of data with move permission restriction recorded on a medium according to the first embodiment of the present invention.
[0054]
In the “common processing block” shown in FIG. 2 (processing from step S201 to step S203), when it is determined that the data to be copied or moved is the data with copy permission restriction or the data with move permission restriction, In step S <b> 401, the main control unit / main memory 104 refers to the right information and determines whether or not copying or moving is permitted (whether or not copying or moving is permitted). If the data has been permitted to be copied or moved, the process proceeds to step S410, and the data is copied or moved. The copy processing or move processing in step S410 will be described later in detail. It should be noted that the case where copying or moving is permitted indicates that information indicating that copying or moving is permitted is written in the right information of the data recorded in advance in the medium 108 together with the data.
[0055]
On the other hand, if the copy or move is not permitted, in step S402, the main control unit / main memory 104 compares whether or not the same unique ID as the data exists in the management information table. If the same unique ID exists, the process proceeds to step S410, this data is determined to be data for which copy permission or move permission has already been obtained, and copy or move is permitted, and copy processing or move processing of the data is performed. Done.
[0056]
Here, the data copy or move processing in step S410 will be described. In the copy or move processing in step S410, the data copy and move processing device manages the data to be copied or moved from the data receiver / transmitter 102 and the data to be copied or moved stored in the nonvolatile memory 111. This is a process of outputting the information table to the outside. In the case of the move process, a process of deleting the data subjected to the move process from the medium 108 is further performed. By simultaneously outputting the management information table stored in the nonvolatile memory 111 together with the data to be copied or moved, the data to be copied or moved is stored in the nonvolatile memory 111 of the data copy and move processing device. It is possible to copy or move in association with the copy permission information and the move permission information which have been set.
[0057]
In addition, reproduction restriction information (reproduction permission restriction information, reproduction frequency restriction information, reproduction cumulative time restriction information, reproduction date restriction information, etc.) relating to the data to be copied or moved may be stored in the nonvolatile memory 111 in some cases. . In this case, in step S410, it is possible to output the reproduction restriction information together with the data to be copied or moved. This makes it possible to copy not only the data to be copied or moved, but also the reproduction permission information stored in the nonvolatile memory 111 of the data copy and move processing device.
[0058]
It is also possible to simultaneously output right information relating to data to be copied or moved recorded on the medium (recording medium) 108. As a result, the content of the original right information recorded on the medium (recording medium) 108 and information on other rights not described in the management information table can be attached to the data to be copied or moved. It becomes. It is also possible to output the reproduction restriction information in the nonvolatile memory 111 at the same time. As a result, the data to be copied or moved can reflect the reproduction restriction set by the data copy and move processing device.
[0059]
On the other hand, if the same unique ID as the data does not exist in the management information table, the process from step S403 is performed. Even if the unique ID exists, for example, when a decryption key (encryption key) for decrypting the data does not exist (or when copying or moving is impossible due to a change in the decryption key or the like). And the like), it is also possible to perform the processing after step S403.
[0060]
Next, in step S403, it is confirmed whether it is possible to obtain a copy permission or a move permission for the data. For example, when it is necessary to connect to an external Internet or the like in order to obtain a copy permission, an attempt is made to connect to the outside via the right information separating / combining unit 103 and the data receiver / transmitter 102 shown in FIG. If connection is possible, the process proceeds to step S404. If connection is not possible (for example, if the line is disconnected or connection to the Internet is not permitted), in step S420, copying is not permitted, that is, copying is not possible. And ends. The same is true for move permission.
[0061]
In step S404, an actual copy or move permission process is performed. Conventionally, there are various types of copy permission processes and move permission processes. For example, there is a method in which a predetermined server at the connection destination performs a charging process for copying or moving the data and obtains a copy permission or a move permission from the predetermined server. In this case, a decryption key (encryption key) may be supplied together with the copy permission or the move permission. There is also a method in which a copy permission or a move permission is obtained by a user inputting a password. In this case, the user is required to input a password via the user interface unit 101 shown in FIG. 1, and by communicating with a predetermined server to which the user is connected, it is confirmed whether or not the password is correct. Is done. In the present invention, the method for obtaining the copy permission or the move permission is not limited to the above method, and any method for obtaining the copy permission or the move permission can be used.
[0062]
When the copy permission or the move permission is acquired from the outside in step S404, the unique ID and the copy permission restriction information or the move permission restriction information (such as the decryption key) are newly added to the management information table in step S405, and the management is performed. Update the information table. Then, in step S406, a copy process or a move process of outputting the data to be copied or moved and the management information table of the data to be copied or moved updated in step S405 from the data receiver / transmitter 102 to the outside are performed. Do. As in step S410, the output of the data to be copied or moved and the reproduction restriction information related to the data to be copied or moved, and the data to be copied or moved recorded on the medium (recording medium) 108, are performed. It is also possible to output such right information at the same time.
[0063]
Further, in step S407, the memory writing / reading unit 110 performs a process of writing back the updated management information table to the nonvolatile memory 111, and ends. On the other hand, if the copy permission or the move permission cannot be obtained from the outside in step S404, the copy or move of the data is not permitted in step S420, that is, the copy or move becomes impossible and the process ends.
[0064]
In the above-mentioned permission, there is a case where a predetermined server as a licensee confirms an ID unique to the player (player-specific ID), and then gives a copy permission or a move permission only to the predetermined player. . In such a case, the player unique ID is transmitted from the data copy and move processing device to a predetermined server to obtain a copy permission and a move permission, and further, the player specific ID is stored in the management information table of the nonvolatile memory 111. It is also possible to record the ID.
[0065]
As described above, in the first embodiment of the present invention, the copy permission or the move permission of the data on the medium 108 is read from the non-volatile memory 111 readable and writable by the data copy and move processing device. Is written, it is possible to copy the data with copy permission restriction or move the data with move permission restriction without rewriting the right information recorded on the medium 108. Further, in particular, when the nonvolatile memory 111 is fixedly installed inside each data copy and move processing apparatus, copy permission or move permission is performed for each data copy and move processing apparatus. It is possible to reliably perform data copy permission management, move permission management, prevention of illegal data copy, and the like. Therefore, the data for which the copy permission or the move permission has been obtained by the predetermined data copy and move processing apparatus can be copied or moved thereafter without receiving the external copy permission or move permission. On the other hand, the nonvolatile memory 111 can be made detachable from the data copy and move processing device. This allows the user to carry the medium 108 and the non-volatile memory 111, and by reading the data on the medium 108 and the management information table in the non-volatile memory 111, the data can be transferred by another data copy and move processing device. Copying or moving becomes possible.
[0066]
In addition, since the management information table in the non-volatile memory 111 of the data copy and move processing device is output together with the data output to the outside for the copy or move, the copy destination or the move destination device performs the data copy and the move. Copy processing or move processing can be performed again in accordance with the contents of the management information table updated by the move processing device. Further, by simultaneously outputting the reproduction restriction information of the data to be copied or moved to the outside at the same time, the reproduction restriction set in the nonvolatile memory 111 of the data copy and move processing device at the copy destination or move destination is obtained. Can be reflected.
[0067]
<Second embodiment>
Next, a description will be given of a second embodiment of processing relating to copying of data with a limited number of copies recorded on the medium 108 and processing relating to the movement of data having a restricted move permission according to the present invention. FIG. 5 is a flowchart for explaining copy processing and move processing of data with a limited number of copies recorded on a medium according to the second embodiment of the present invention.
[0068]
In the “common processing block” shown in FIG. 2 (processing from step S201 to step S203), when it is determined that the data to be copied or moved is the data with the copy number limitation or the data with the move number limitation, In S501, the main control unit / main memory 104 compares whether or not the same unique ID as the data to be copied or moved exists in the management information table.
[0069]
If the same unique ID exists in step S501, in step S502, the copy number restriction information (copy number restriction information shown in FIG. 3) or the move number restriction information (the move number restriction shown in FIG. 3) in the management information table. Information) is zero or not. In the management information table of FIG. 3, in the case of data with copy number limitation or data with move number limitation, the remaining copy number (the number of times that copying is possible) is shown as copy number limitation information, and the copy number limitation information is The remaining number of moves (the number of times the move is possible) is shown. In addition, in the case of data having no copy number limitation or move number limitation, “no information” is recorded in the copy number limitation information or the move number limitation information.
[0070]
If the value of the copy count restriction information or the move count restriction information in the management information table is other than zero, copying or moving is permitted, and in step S510, the data to be copied or moved and the data updated in step S405. Copy or move processing for outputting the management information table of data to be copied or moved from the data receiver / transmitter 102 to the outside is performed. Note that, similarly to step S410 in the first embodiment, together with the output of the data to be copied or moved, the reproduction restriction information on the data to be copied or moved and the media (recording medium) 108 are recorded. It is also possible to simultaneously output the right information on the data to be copied or moved. If the value of the copy count restriction information or the move count restriction information in the management information table is zero, in step S520, copying or moving of the data is not permitted, that is, copying or moving becomes impossible. To end. Although the detailed description is omitted here, when the value of the copy count restriction information or the move count restriction information is zero, the same processing as that after step S403 of the first embodiment is performed, and a predetermined server is executed. To obtain the copy count (ie, increase the value of the copy count restriction information) and the move count (ie, increase the value of the move count restriction information), thereby restricting the copy or move of the data. It is also possible to enable cancellation.
[0071]
On the other hand, when the same unique ID does not exist in step S501 (that is, when the data is copied or moved for the first time), in step S503, the main control unit / main memory 104 is written in the right information. The unique ID of the data and the copy count restriction information (remaining copy count) or the move count restriction information (remaining move count) are added to the management information table of the nonvolatile memory 111 via the memory writing / reading unit 110. . Thus, when the data is copied or moved for the first time, the maximum number of copies or the maximum number of moves included in the right information of the data is recorded in the management information table of the nonvolatile memory 111. In step S510, a copy process or a move process of outputting the data to be copied or moved and the management information table of the data to be copied or moved updated in step S405 from the data receiver / transmitter 102 to the outside are performed. Do. Note that, similarly to step S410 in the first embodiment, together with the output of the data to be copied or moved, the reproduction restriction information on the data to be copied or moved and the media (recording medium) 108 are recorded. It is also possible to simultaneously output the right information on the data to be copied or moved.
[0072]
In step S510, a copy or move process is performed to copy or move the data once. If the one copy or move is completed, in step S511, the copy or move number limit information of the management information table is deleted. The value is decremented by one, and the management information table is copied or the move count restriction information is updated. The determination of “one copy or move is completed” may be made when all (100%) data is copied or moved, or may be copied or moved to some extent (for example, 50% or more). It is preferable to define the definition in advance, such as whether to perform once. For example, when the copy or move is forcibly terminated and the number of copies or moves according to the above definition is less than “one time”, the copy of the management information table or the update of the number-of-moves information is not performed. Further, in step S512, the memory writing / reading unit 110 performs a process of writing back the updated management information table to the nonvolatile memory 111, and ends.
[0073]
As described above, in the second embodiment of the present invention, the number of times of copying or moving data on the medium 108 is read from the nonvolatile memory 111 which is readable and writable by the data copying and moving processing device, and When copying or moving for the first time, the maximum number of copies or the maximum number of moves specified in the right information in the medium 108 is written, so the right information recorded on the medium 108 must be rewritten. In addition, it is possible to copy or move data with copy or move count restriction. In particular, when the non-volatile memory 111 is fixedly installed inside each data copy and move processing device, the number of copies or the number of moves is limited for each data copy and move processing device. It is possible to reliably manage the number of times of copying or moving data within the device and prevent the copying or moving of unauthorized data. On the other hand, the nonvolatile memory 111 can be made detachable from the data copy and move processing device. This allows the user to carry the medium 108 and the non-volatile memory 111, and by reading the data on the medium 108 and the management information table in the non-volatile memory 111, the data can be transferred by another data copy and move processing device. Copying or moving becomes possible.
[0074]
In the above-described first and second embodiments of the present invention, the management information updated and written back to the nonvolatile memory can be recorded in the medium 108 as new right information. It is. Thereby, for example, the copy or move permission restriction that allows unlimited copying or moving of the data of the medium 108 is released (first embodiment), and the data of the medium 108 can be copied or moved without being limited by the number of times. And the release of the limit of the number of moves can be acquired, it is possible to record that fact on the medium 108.
[0075]
Also, in the first and second embodiments of the present invention, the management information table (unique ID and various types of copy restriction information or various types of copy restriction information) is stored in the nonvolatile memory 111 in the data copy and move processing apparatus. By recording the move restriction information, data with copy restriction can be copied and data with move restriction can be moved even in a data copy and move processing apparatus having no recording function on the medium 108. Although disclosed, the present invention is not limited to the above two types of copy restrictions (copy permission restrictions and copy number restrictions) and the two types of move restrictions (move permission restrictions and move number restrictions). It is also applicable for copy restriction or move restriction. For example, as another copy restriction or move restriction, the amount of data that can be copied or moved on each recording medium is defined, and a case where copying or moving of data is permitted up to the defined amount, By recording information on the remaining capacity that can be copied or moved in the non-volatile memory 111 according to the technique of the present invention, it is also possible to manage data copy restrictions or move restrictions.
[0076]
The flowcharts shown in FIGS. 2, 4, and 5 can be executed and controlled mainly by the main control unit / main memory 104. That is, a program that enables the data copy and move processing method of the present invention to be executed is stored in a storage unit of the main control unit / main memory 104 or another program storage unit. The data copy and move processing method of the present invention can also be executed by executing the program by means of the program 104.
[0077]
【The invention's effect】
As described above, according to the present invention, when performing copy or move processing of reading data on a medium (recording medium) and outputting the read data to the outside, the copy restriction or move restriction on data to be copied or moved is restricted. Since the data is read from the non-volatile memory, it is possible to manage the copy of the data with copy restriction or the management of the move of the data with move restriction without rewriting the right information recorded on the medium. Further, after the data copy or move processing, the copy limit or move limit of the copied or moved data is updated according to the copy result or move result of the data. Alternatively, it is possible to reliably comply with the move restriction.
