Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information processing apparatus such as a personal computer and an information processing method that acquire predetermined information such as content and its right information by following predetermined service specifications and make the information available.
[0002]
[Prior art]
Currently, for example, audio compact discs (CD) or CD-ROMs are mass-produced and used in various applications. However, such information on the recording medium is written and illegally copied to a writable recording medium such as a hard disk device or a CD-R.
[0003]
Accordingly, various techniques for preventing this have been developed. For example, Patent Document 1 below describes a technique related to a recording medium in which the subcode Q field is changed to be an encryption key to prevent copying. In the technique described in Patent Document 1, even if the subcode Q field is changed in advance, the subcode Q field is changed in advance by using a feature that becomes a normal subcode Q field when copied. This is used as an encryption key. As a result, the encryption key cannot be generated from the copied CD, and therefore the reproducing apparatus cannot read the data, so that copying can be prevented.
[0004]
Recently, a service specification that combines these copy protection technologies in combination, performs network authentication with the serial number that is the authentication information, and obtains an encryption key, etc., for decrypting the encrypted content as a license. Digital media are provided.
[0005]
Such digital media is an authentication type copy control CD using a network in order to properly protect the rights of the lyricist, composer, artist, etc. in consideration of the needs and convenience of music users. There is a first session area in which audio data that can be played back only by an audio CD device is recorded, an encrypted compressed sound source file for playback on a PC (Personal Computer), and a copy of the file on a PC for playback. A second session area in which the software is recorded and a serial number (individual ID (identity) written after pressing) unique to each disk are recorded.
[0006]
The user can view the digital media on an audio CD device in the same way as a normal CD and can also play it back on a PC. When playing back on a PC, the user can use the serial number to access an authentication server. It cannot be played without access and authentication. The authentication server manages the number of authentications for each serial number. For example, the first time is free, the second time is charged, etc. Charges are generated according to the number of authentications, and unauthorized copying must be done. Prevented service specifications.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments to which the present invention is applied will be described in detail with reference to the drawings. In this embodiment, the information according to the present invention allows the content to be used by obtaining the use permission of the content after being authenticated by the identification ID described in the recording medium by a method according to a predetermined service specification. This is applied to a processing apparatus.
[0018]
First, three typical examples of various service forms will be described. FIGS. 1A to 1C are schematic diagrams for explaining digital media service specifications 1 to 3 as examples of various service forms. Here, the service specification means, for example, how the content (music, video, etc.) recorded on a digital medium as a recording medium, along with a license (encryption key, etc.) for reproducing them, in what procedure the client terminal In addition, it indicates whether it is handled by the distribution system server (authentication server) if necessary.
[0019]
Service specifications 1, 2, and 3 indicate the types of service specifications assumed by each digital media. The content C is digital data such as music or a movie, for example, and the service provider has a license L as a right to use it.
[0020]
In the service specification 1 shown in FIG. 1A, the medium 11 has a content C and a license L that permits the use of the content C. The client terminal 12 that uses the content can reproduce the content C by importing the content C and the license L.
[0021]
Further, in the service specification 2 shown in FIG. 1B, the media 21 has a content C and an authentication ID for performing authentication, user registration, and the like for using the content C. Furthermore, an application that automatically performs authentication, user registration, and the like to acquire a license for the content C, and dedicated software that reproduces the content C may be included. The client terminal 22 uses the application of the media 21 to acquire a license to use the content C, and therefore identifies the media 21 to the authentication server 23 that performs authentication of, for example, an EMD (music distribution system) server via the network. When the ID is transmitted and authentication is received, the license L is sent from the authentication server 23, and the content C recorded on the medium 21 can be reproduced.
[0022]
Also, in the service specification 3 shown in FIG. 1C, the media 31 has an authentication ID for performing authentication, user registration, and the like for using the content C. Further, an application that automatically performs authentication, user registration, and the like to acquire the license of the content C and the content C, and dedicated software that reproduces the content C may be included. The client terminal 32 transmits an authentication ID to an authentication server 33 such as an EMD server by an application for authentication / registration of the media 31. Upon receiving the authentication, the client terminal 32 receives a license L and content C from the authentication server. The content C can be reproduced. Note that the server that authenticates authentication from the client terminal and the server that distributes content may be separate.
[0023]
When a dedicated application for reproducing the content C is necessary, it is recorded in advance in the media 11 to 31 and the client terminal 12 to 32 installs the application for reproduction from the media 11 to 31 as necessary. To be able to. Further, as shown in FIG. 1B and FIG. 1C, in a client terminal capable of transmitting and receiving data via a network, when a dedicated application for reproducing the content C is required, These applications may also be downloaded from, for example, an authentication server or a server managed by a service provider. In this case, the download destination may be described on the media, or the download destination may be sent from the distribution system. Furthermore, when the content C is encrypted, it is assumed that a decryption key for decrypting the encrypted content can be acquired by acquiring the license L.
[0024]
The client terminals 12 to 32 as information processing apparatuses in the present embodiment are, for example, PCs, and as shown in FIG. 2, a CPU (Central Processing Unit) 71, a ROM (Read Only Memory) 72, a RAM (Random) An access memory 73, a hard disk drive (HDD) 74, a display means 75, a speaker 76, an input means 77 such as a mouse and a keyboard, a reading means 78 for reading data from a medium, and the like are connected via a bus 79. . If necessary, the communication means 80 is also connected through the bus 79.
[0025]
For example, when an execution instruction for a predetermined process is given by operating the input means 77, the CPU 71 executes a predetermined operation based on a program stored in the ROM 72, whereby various processes are performed as the entire client terminal. Has been made to run.
[0026]
Here, in the present embodiment, the service specifications that the client terminal follows are based on the premise that in any case, the content C and the license L can be played back (used) only after a set of the content C and the license L. It has become.
[0027]
Next, a content use procedure in the service specifications 1 to 3 will be described. The digital media 11 shown in FIG. 1A has the content C and the license L as described above. As an example of service specification 1 using such media 11, first, the user imports content C and license L from digital media 11 at client terminal 12. The content C is data that can be reproduced by the license L, and the client terminal 12 that has acquired the license L can reproduce the content C. At this time, for example, communication with a content distribution system such as an EMD (music distribution system) server does not occur. As described above, when a dedicated application for using the content C is necessary, the application is recorded on the medium 11 together with the content C and the license L, and the client terminal 12 imports this application as well. It may be.
[0028]
Further, the medium 21 shown in FIG. 1B has the identification ID of the content C and the medium 21 as described above. As an example of the service specification 2 using such a medium 21, first, the client terminal 12 reads the identification ID of the medium 21 and transmits it to the content distribution system (in this service specification 2, the authentication server 23). Then, digital media authentication and user registration are performed.
[0029]
Next, the client terminal 22 imports the content C from the digital media 21. When authenticating the above-described identification ID transmitted from the client terminal 22, the authentication server 23 transmits a license L for enabling the use of the content C to the client terminal 22. That is, the client terminal 22 downloads the license L from the authentication server 23 serving as a content distribution system. Thus, the client terminal 22 that has acquired the content C and the license L can reproduce the content C.
[0030]
Further, as described above, the authentication / registration process may be performed by a user instruction from the client terminal 22. However, when the medium 21 is mounted on the drive of the client terminal 22, for example, the authentication / registration process is automatically performed. A license acquisition application that downloads the license L when processing is performed and the user obtains consent may be installed.
[0031]
As described above, the network authentication type copy-controlled CD that can be set as the service specification 2 includes a first session area in which audio data that can be reproduced only by an audio device is recorded, and a client terminal. It may have a second session area in which reproducible data is recorded and an identification ID unique to the medium itself used for authentication.
[0032]
In the second session area, an authentication / registration application for performing processing for obtaining a license by performing authentication and registration with an identification ID, a dedicated application for reproduction on a PC, and a client terminal such as a PC An encrypted compressed sound source file as content to be used is recorded. The client terminal transmits an authentication ID to the authentication server. If the client terminal is not authenticated, the client terminal cannot acquire a license and cannot reproduce the content, thereby preventing unauthorized copying of the content.
[0033]
Further, the medium 31 shown in FIG. 1C has only the identification ID as described above. As an example of the service specification 3 using such a medium 31, first, the client terminal 32 reads the identification ID from the medium 31 and transmits it to the authentication server 33 to perform authentication / registration. When authenticating this identification ID, the authentication server 33 transmits the content C and its license L. That is, the client terminal 32 can download the content C and the license L from the authentication server 33 of the content distribution system, for example, by automatically performing authentication / registration processing when the media 31 is loaded in the drive. In this way, the client terminal 32 that has acquired the content C and the license L can reproduce the content C.
[0034]
As described above, in the digital media service specifications 1 to 3 in the present embodiment, the use procedure of the content C is mainly processed by the application on the digital media 11, 21 or 31 and the digital media 11 to 31. The inserted client terminals 12 to 32 (or applications on the client terminals 12 to 32). By the way, when the digital media 11 to 31 are inserted into the drive, the processing procedure expected by the media 11 to 31 is, for example, the service specification 1 in FIG. 1, the service specification 2, or the service specification. Whether it is 3 or not cannot be judged unless there is any clue.
[0035]
Therefore, in the present invention, in order to provide such a clue, service identification information for identifying a service specification is described on a medium. Hereinafter, this service identification information will be described in detail. FIG. 3 is a diagram showing a format specification example of service identification information (hereinafter referred to as service identifier).
[0036]
As shown in FIG. 3A, the service identifier 40 is a service type (Service Type) as first identification information indicating which service specification corresponds to a plurality of service specifications as described above. ) 41 and a major version 42 and a minor version 43 as second identification information indicating the version information of the application used in the service specification.
[0037]
As shown in FIG. 3B, the service type 41 has a data size of, for example, 2 bytes. For example, 0x0001 indicates the digital media service specification 1, and 0x0002 indicates the digital media service specification 2. It can be shown. The major version 42 has a data size of, for example, 2 bytes. For example, if the major version 42 is 0x0001, it can indicate that the major version is 1. Further, the minor version 43 has a data size of, for example, 2 bytes. For example, if the minor version 43 is 0x0003, it can indicate that the minor version is 3.
[0038]
Then, the client terminal uses the plurality of service specifications 1 to 1 described above that allow the client terminal to use predetermined information such as contents around the medium on which service identification information indicating the service specifications provided by the media is written. 2, at least reading means 78 for reading out service identification information from the medium as shown in FIG. 2 and identification means for identifying whether or not the service specification provided by the medium can be supported (FIG. 2). And an acquisition means (not shown) for acquiring information and its right information by performing processing according to the service specification when the service specification provided by the recording medium can be handled.
[0039]
Further, the client terminal stores information on service specifications and versions of digital media that can be handled by itself, that is, information equivalent to the service identifier described in the digital media (hereinafter referred to as corresponding service identification information) in a dedicated registry. Keep a record. The identification unit compares the corresponding service identification information with the service identifier, and performs processing such as determining whether or not the service specification provided by the medium can be handled, and the acquisition unit acquires the license and the content. These processes are performed, for example, by a client terminal or an application on the client terminal.
[0040]
Further, by disclosing the corresponding service identification information on the client terminal or the application side on the client terminal, it is known from the application on the digital media whether the environment of the client terminal into which the digital media is inserted can satisfy the service specifications. be able to.
[0041]
In this way, by identifying the service identifier, the client terminal can correctly process the service expected by the digital media when the digital media having a certain service identifier 40 is inserted into the drive of the client terminal. The client terminal can know whether or not. That is, the client terminal compares the service identifier with its corresponding service identification information, and can determine whether or not the client terminal can support the service specification provided by the media. As a result, the client terminal or the client terminal and the content distribution system linked with the client terminal conventionally have no way of knowing whether the service is compatible with the service when the service specification is upgraded. As described above, the service identifier indicating the service specification provided by itself is recorded on the medium, and the client terminal has the corresponding service identification information as service specification information that can be supported by the client terminal. Can be individually upgraded in different service specifications.
[0042]
In addition, since the client terminal has the corresponding service identification information, the application on the digital media can check the environment of the client terminal. For example, a dedicated application for reproducing the content provided by the digital media itself can be used. Information that is not installed on the client terminal or the version of the installed application is old can be acquired, and in this case, processing for installing an optimal application for content playback on the client terminal may be performed. it can. The application to be installed on the client terminal may be recorded on the digital media, and also has information such as an address for the digital media to download the application via the network, and the client terminal accesses this address. Then, a process of downloading a necessary application may be performed.
[0043]
4 (a) and 4 (b) show how to use service identifiers. Hereinafter, an application that is executed on the disk without being imported to the client terminal, such as the above-described authentication / registration process, is referred to as an on-disk application. Further, an application that is a dedicated application for reproducing the content C and that is installed in the client terminal is referred to as an installed application.
[0044]
A medium 51 shown in FIG. 4A is recorded with at least a service identifier 52 and an on-disk application A. The medium 51 corresponds to the service specification 2 and can be identified by the service identifier 52 that the version is 1.2 (major version: 1, minor version: 2).
[0045]
The client terminal also records at least a service specification type and version information corresponding to the service identification information as corresponding service identification information in a dedicated registry. FIG. 4A shows a case where both the installed application (player) B and the installed application (player) C installed in the client terminal can handle the digital media 51 defined by the service identifier 52. . This is because when the installed application installed in the client terminal and the application recorded in advance on the digital media operate in cooperation to provide a service, the on-disk application A is the installed application B. Even if it exists, even if it is the installed application C, it has shown that it can be guaranteed that it can cooperate.
[0046]
The corresponding service identification information recorded in the dedicated registry includes, as with the service identifier, the service specification type and version that can be supported, as well as information required by the service specification, such as a network authentication type service. If it is a specification, it can also have information such as the address of the authentication server.
[0047]
The media 61 shown in FIG. 4B also has at least a service identifier 62 and an on-disk application D. The disk 61 corresponds to the digital media service specification 2 and can be identified by the service identifier 62 that the version is 1.2.
[0048]
The installed application (player) E installed in the client terminal corresponds to the service specification 2 and its version is 1.1. The installed application (player) F has the service specification 3 The version is 1.2.
[0049]
In this case, the digital media 61 defined by the service identifier 62 cannot be handled. That is, the installed application E has an older version than the media 61, and the installed application F has a different specification from the media 61. When the installed application installed in the client terminal and the on-disk application on the media recorded in advance on the digital media 61 operate in cooperation to provide a service, the on-disk application D is This shows that it is possible to clearly determine that the installed application E and the installed application F cannot be linked.
[0050]
Here, the client terminal reads the service identifier of the inserted media 51 and 61 and compares the service identifier with its corresponding service identification information, thereby providing service specifications provided by the media 51 and 61 inserted into the client terminal itself. 4A, the client terminal itself can know whether or not the client terminal itself can handle, and as shown in FIG. 4A, when the client terminal itself is compatible, processing according to the service specification provided by the media 51 can be performed. As shown in FIG. 4B, when the client terminal does not correspond to the service specification provided by the media 61, the user is notified to that effect or the necessary application is imported from the media 61 to the client terminal. Or download necessary applications via the network. Whether the client terminal supports or does not support the service specification provided by the client, the processing on the client terminal side is expedited by reading and identifying the media service identifier. .
[0051]
The media 51, 61 also recognizes information equivalent to the service information recorded in the dedicated registry of the client terminal in which the media 51, 61 itself is inserted, so that the client terminal can identify the media 51, 61 itself. For example, when the client terminal does not support the service specification provided by the media 62 as shown in FIG. 4B, the media 61 can Processing that installs an application necessary for the service specification provided by the client terminal on the client terminal, that is, if the necessary application is recorded on the media 61, the application is imported to the client terminal or downloaded via the network. Or give instructions. Thereby, also on the media side, the processing is speeded up by reading information equivalent to the service identifier recorded in the client terminal.
[0052]
In the present embodiment configured as described above, when the service providing entity provides various additional services in cooperation with the content distribution system and the client terminal including the application on the client terminal around the digital media, By recording in advance the service identifier having the type of the service specification and the version information of the service specification on the digital media to be released, the service provider, the content distribution system developer, and the client terminal developer Can share the service specification specified by this service identifier. As a result, the following framework can be established.
[0053]
That is, the service providing entity can provide an open and clear service specification to the content distribution system developer and the client terminal developer. In addition, the service providing entity can provide a consistent quality service to the user by the content distribution system and the client terminal corresponding to the service specification.
[0054]
Furthermore, even if a plurality of service providing entities develop additional services with a plurality of specifications on a plurality of types of digital media and further upgrade the service specifications individually, the service specifications can be managed in an orderly manner. Furthermore, when the user enjoys the additional service, the client terminal corresponding to the service identifier can be freely selected. Then, it is possible to know from the application on the digital media whether or not the client terminal environment into which the user is inserted can satisfy the service specifications.
In addition, it is possible to diversify additional services linked to content distribution systems and client terminals (including applications on client terminals), and platforms that can handle the above-mentioned digital media. Digitalized media can be spread.
[0055]
It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the present invention. For example, it has been described that content such as music or video can be used in the client terminal by the service provided by the above-described digital media. However, the predetermined information that can be used in the client terminal includes content. For example, it may be a program or the like.
[0056]
