  The content reproduction system 10 includes a plurality of ICCs having the same configuration as the ICC 20 and a plurality of usage devices having the same configuration as the usage device 40, separately from the ICC 20 and the usage device 40. For example, the content reproduction system 10 includes an ICC 120 having the same configuration as the ICC 20 and a use device 140 having the same configuration as the use device 40.

  Next, the operation of the content reproduction system 10 will be described.

  In the following, the case where the ICC 20 and the utilization device 40 are combined will be described. However, when the ICC 20 and the utilization device 140 are combined, when the ICC 120 and the utilization device 40 are combined, or the ICC 120 and the utilization device 140 are combined. Even when the ICC 20 and the utilization device 40 other than the ICC 20 and the utilization device 40 are combined, the content reproduction system 10 operates in the same manner as when the ICC 20 and the utilization device 40 are combined.

  First, when the use device 40 can communicate with the ICC 20, the playback unit 41 of the use device 40 receives a list of content IDs of reproducible content (hereinafter referred to as “playable ID list”) from the control unit 43. An operation of the content reproduction system 10 will be described. When the playback unit 41 of the usage device 40 receives the reproducible ID list from the control unit 43, the usage device 40 does not need to be in a state in which the usage device 40 can communicate with the server 60.

  As shown in FIG. 4, when the playback unit 41 requests the control unit 43 to output a reproducible ID list (step 201), the control unit 43 requests the ICC 20 to output the user PF (step 201). 202).

  When the control unit 43 requests the ICC 20 to output the user PF, the ICC 20 outputs the stored user PF to the control unit 43 of the utilization device 40 (step 203).

  When the user PF is output by the ICC 20, the control unit 43 receives the user PF output by the ICC 20, verifies the electronic signature of the user PF, and then requests the SC 42 to output the device PF ( Step 204).

  When the control unit 43 requests that the device PF be output, the SC 42 outputs the stored device PF to the control unit 43 (step 205).

  When the device PF is output by the SC 42, the control unit 43 receives the device PF output by the SC 42, verifies the electronic signature of the device PF, and then requests the SC 42 to search for usage right information (step 206). ).

  When the control unit 43 is requested to search for the usage right information, the SC 42 searches all the usage right information stored therein, and a list of content IDs and reproduction condition information in the usage right information (hereinafter, “ After creating the “ID condition list”, the created ID condition list is output to the control unit 43 (step 207).

  When the ID condition list is output by the SC 42, the control unit 43 receives the ID condition list output by the SC 42 and then requests the ICC 20 to search for usage right information (step 208).

  When the control unit 43 requests the ICC 20 to search for usage right information, the ICC 20 searches all the usage right information stored therein, that is, a list of content IDs and playback condition information in the usage right information, that is, After creating the ID condition list, the created ID condition list is output to the control unit 43 of the using device 40 (step 209).

  When the ID condition list is output by the ICC 20, the control unit 43 receives the ID condition list output by the ICC 20, and then receives the user PF received from the ICC 20, the device PF received from the SC 42, the SC 42 and the ICC 20. Based on the received ID condition list, the content search unit 45 searches the content ID satisfying the reproduction conditions by the user PF and the device PF (step 210). For example, the user's age from the date of birth of the user in the user PF received from the ICC 20 is “17 years old”, and the manufacturer of the user device 40 is determined from the ID of the manufacturer in the device PF received from the SC 42. When “Company A” is selected, the content ID of the content whose reproduction condition is “User is 18 years old or older and the manufacturer of the device used is Company B”, or the reproduction condition is “User is 18 years old or older and the device used is The content search unit 45 does not search the content ID of the content whose manufacturing company is “Company A” or the content ID of the content whose playback condition is “user 15 years of age or older and the manufacturer of the device used is B company”. The content search unit 45 searches for the content ID of the content whose playback condition is “user is 15 years old or older and the manufacturer of the used device is company A”.

  Next, the control unit 43 creates a list of content IDs searched in step 210, that is, a playable ID list (step 211), and outputs the created playable ID list to the playing unit 41 (step 212).

  Then, the reproduction unit 41 receives the reproducible ID list output by the control unit 43, and based on the reproducible ID list received from the control unit 43, for example, the reproducible content is displayed to the user by display or audio. Notice.

  The control unit 43 requests the ICC 20 to output the user PF, the request to the SC 42 to output the device PF, the request to the SC 42 to search for usage right information, and the usage right. The request to the ICC 20 to search for information may be performed in an order other than the order described above.

  The control unit 43 searches for the content ID based on both the user PF received from the ICC 20 and the device PF received from the SC 42. However, depending on the reproduction conditions, the user PF received from the ICC 20 is searched. The content ID may be searched based on only one of the devices PF received from the SC 42.

  Next, in a state where the use device 40 can communicate with the server 60 and the ICC 20, the operation of the content reproduction system 10 when the reproduction unit 41 of the use device 40 confirms whether or not the usage right information of the content can be obtained. Will be described.

  As shown in FIG. 5, the playback unit 41 confirms whether or not the content usage right information can be obtained by outputting the content ID of the content for which the usage right information is desired to be output to the control unit 43. This is requested to the control unit 43 (step 231).

  When it is requested by the playback unit 41 to check whether or not the usage right information of the content is available, the control unit 43 stores the content ID output by the playback unit 41 in step 231 and stores the membership card. The server 60 is requested to acquire information from the ICC 20 (step 232).

  When the control unit 43 requests that the membership card information be acquired from the ICC 20, the server 60 requests the ICC 20 to output the membership card information via the control unit 43 of the utilization device 40 (step 233).

  When the ICC 20 is requested by the server 60 to output membership card information, the ICC 20 outputs the stored membership card information to the server 60 via the control unit 43 of the utilization device 40 (step 234).

  When the membership card information is output by the ICC 20, the server 60 receives the membership card information output by the ICC 20, and then performs authentication by verifying the electronic signature of the received membership card information (step 235).

  Then, when the authentication in step 235 is successful, the server 60 requests the ICC 20 to output the user PF via the control unit 43 of the utilization device 40 (step 236).

  When it is requested by the server 60 to output the user PF, the ICC 20 outputs the stored user PF to the server 60 via the control unit 43 of the utilization device 40 (step 237).

  When the user PF is output by the ICC 20, the server 60 receives the user PF output by the ICC 20, verifies the electronic signature of the user PF, and then outputs the device PF. The request is sent to the SC 42 of the using device 40 via the terminal 43 (step 238).

  When the server 60 requests that the device PF be output, the SC 42 outputs the stored device PF to the server 60 via the control unit 43 (step 239).

  When the device PF is output by the SC 42, the server 60 receives the device PF output by the SC 42, verifies the electronic signature of the device PF, and then performs the step 239 by the user PF and SC 42 output by the ICC 20 in step 237. The device PF output at step 237 is stored in association with the user ID in the user PF output at step 237 by the ICC 20 (step 240), and the user ID stored at step 240 is stored in the control unit 43 of the user device 40. (Step 241).

  When the user ID is output by the server 60, the control unit 43 receives the user ID output by the server 60, and associates the received user ID with the content ID output by the playback unit 41 in step 231. (Step 242), the playback unit 41 is notified of the result that the playback right of the content is available to the playback unit 41 (step 243). Here, when the authentication by the server 60 in step 235 fails, the control unit 43 notifies the reproduction unit 41 of the result that the reproduction unit 41 cannot obtain the content usage right information.

  In the above description, “membership card information” is obtained from the ICC when verifying whether usage right information is available, and electronic signature verification is performed, but this may be omitted depending on the type of service and the operation mode. Is possible.

  Note that the server 60 performs the above-described order of the request to the ICC 20 to output the membership card information, the request to the ICC 20 to output the user PF, and the request to the SC 42 to output the device PF. You may carry out in order other than.

  Next, when the reproduction unit 41 of the usage device 40 receives the result that the usage right information of the content is available in the process shown in FIG. The operation of the content reproduction system 10 when content usage right information is stored will be described.

  As shown in FIG. 6, the playback unit 41 controls the output of content usage right information by outputting the same content ID as the content ID output in step 231 (see FIG. 5) to the control unit 43. Request is made to the unit 43 (step 261).

  When the playback unit 41 requests that the content usage right information be output, the control unit 43 associates the content ID with the content ID output by the playback unit 41 in step 261 (see FIG. 5). ) And the content ID output by the playback unit 41 in step 261 are output to the server 60, thereby requesting the server 60 to output the content usage right information to the SC 42. (Step 262).

  When the control unit 43 requests the server 60 to output content usage right information to the SC 42, the content ID same as the content ID output by the control unit 43 in step 262 is obtained from the stored content decryption key. The content decryption key associated with is acquired (step 263).

  Next, the server 60 is associated with the same user ID as the user ID output by the control unit 43 in step 262 from the user PF and the device PF stored in step 240 (see FIG. 5). The user PF and the device PF are acquired (step 264).

  Next, the server 60 uses the stored reproduction condition template information, duplication condition template information, and movement condition template information to reproduce the reproduction condition template information associated with the content ID output by the control unit 43 in step 262, and the replication condition template information. Condition template information and movement condition template information are acquired (step 265).

  Then, the usage right creation unit 61 of the server 60 reproduces based on the user PF and device PF acquired in step 264 and the reproduction condition template information, replication condition template information, and movement condition template information acquired in step 265. Condition information, duplication condition information, and movement condition information are created, the created reproduction condition information, duplication condition information, and movement condition information, the content ID output by the control unit 43 in step 262, and the control unit in step 262 The usage right information is created based on the user ID output in step 43, the content decryption key acquired in step 263, and transfer condition information that is either transferable or nontransferable (step 266). Here, the user ID output by the control unit 43 in step 262 becomes the usage right owner ID in the usage right information.

  Next, the server 60 outputs the usage right information created in step 266 to the SC 42 of the usage device 40 via the control unit 43 of the usage device 40 (step 267).

  When the usage right information is output by the server 60, the SC 42 stores the usage right information output by the server 60 and then notifies the server 60 of the result of successful storage of the usage right information via the control unit 43. (Step 268).

  When the server 60 is notified of the result of the successful storage of the usage right information by the SC 42, the server 60 notifies the control unit 43 of the usage device 40 of the result of the successful storage of the usage right information by the SC 42 (step 269).

  When the server 60 notifies the result that the storage of the usage right information by the SC 42 is successful, the control unit 43 further notifies the reproduction unit 41 of the result of the successful storage of the usage right information by the SC 42 (Step 270). .

  The server 60 obtains the content decryption key, obtains the user PF and the device PF, and obtains the reproduction condition template information, the replication condition template information, and the movement condition template information in an order other than the order described above. Also good.

  In the processing shown in FIG. 6, usage right information is output from the server 60 to the SC 42, but the content reproduction system 10 receives the usage right information from the server 60 via the control unit 43 of the usage device 40. The processing output to the ICC 20 can be executed in the same manner.

  Next, an operation of the content reproduction system 10 when content is reproduced by the reproduction unit 41 of the utilization device 40 in a state where the utilization device 40 can communicate with the ICC 20 will be described. When the content is played back by the playback unit 41 of the usage device 40, the usage device 40 does not need to be in a state where it can communicate with the server 60.

  As shown in FIG. 7, the playback unit 41 requests the control unit 43 to output the content decryption key of the content desired to be reproduced by outputting the content ID of the content desired to be reproduced to the control unit 43. (Step 301).

  When the playback unit 41 requests that the content decryption key be output, the control unit 43 requests the ICC 20 to output the user PF (step 302).

  When the control unit 43 requests the ICC 20 to output the user PF, the ICC 20 outputs the stored user PF to the control unit 43 of the utilization device 40 (step 303).

  When the user PF is output by the ICC 20, the control unit 43 receives the user PF output by the ICC 20, verifies the electronic signature of the user PF, and then requests the SC 42 to output the device PF ( Step 304).

  When the control unit 43 requests that the device PF be output, the SC 42 outputs the stored device PF to the control unit 43 (step 305).

  When the device PF is output by the SC 42, the control unit 43 receives the device PF output by the SC 42, verifies the electronic signature of the device PF, and then sets the content ID output by the playback unit 41 in step 301 to the SC 42. By outputting, the SC 42 is requested to output the usage right information corresponding to the content ID to be output (step 306).

  When the control unit 43 is requested to output the usage right information, the SC 42 searches all the stored usage right information, and uses the content ID corresponding to the content ID output by the control unit 43 in step 306. After acquiring the right information, the acquired use right information is output to the control unit 43 (step 307).

  When the usage right information is output by the SC 42, the control unit 43 receives the usage right information output by the SC 42, verifies the electronic signature of the received usage right information, and then outputs the usage right information by the playback unit 41 in step 301. By outputting the content ID to the ICC 20, the ICC 20 is requested to output usage right information corresponding to the content ID to be output (step 308).

  When the control unit 43 requests the ICC 20 to output the usage right information, the ICC 20 searches all stored usage right information and uses the content ID output by the control unit 43 in step 306. After acquiring the right information, the acquired use right information is output to the control unit 43 of the use device 40 (step 309).

  When the usage right information is output by the ICC 20, the control unit 43 receives the usage right information output by the ICC 20, verifies the electronic signature of the received usage right information, and then includes the usage right information received from the ICC 20 or SC 42. Based on the reproduction condition information, the user PF output by the ICC 20 in step 303, and the device PF output by the SC 42 in step 305, the reproducibility determination unit 44 determines whether or not the content can be reproduced. (Step 310). For example, the user's age from the date of birth of the user in the user PF received from the ICC 20 is “17 years old”, and the manufacturer of the user device 40 is determined from the ID of the manufacturer in the device PF received from the SC 42. When the content is “Company A”, the playback condition is “User is over 18 years old and the manufacturer of the equipment used is Company B”, or the playback condition is “User is over 18 years old and the equipment manufacturer of the equipment used is Content that is “Company A” and content whose playback condition is “User 15 years or older and the manufacturer of the device used is Company B” are determined by the reproducibility determination unit 44 to be unplayable, and the playback condition Is determined to be reproducible by the reproducibility determination unit 44, where “the user is 15 years of age or older and the manufacturer of the device used is company A”.

  When determining in step 310 that the content can be reproduced, the control unit 43 acquires a content decryption key from the usage right information used in the determination in step 310 (step 311), and acquires the acquired content decryption key. The key is output to the playback unit 41 together with the content ID output by the playback unit 41 in step 301 (step 312).

  Accordingly, the playback unit 41 receives the content decryption key and the content ID output by the control unit 43 in step 312, and uses the content decryption key output by the control unit 43 in step 312 for the content corresponding to the received content ID. It can be played back while decrypting.

  The control unit 43 sends a request to the ICC 20 to output the user PF, a request to the SC 42 to output the device PF, a request to the SC 42 to output usage right information, and a usage right. The request to the ICC 20 to output information may be performed in an order other than the order described above.

  The control unit 43 determines whether or not the content can be reproduced based on both the user PF received from the ICC 20 and the device PF received from the SC 42. Depending on the reproduction conditions, the ICC 20 It may be determined whether or not the content can be reproduced based on only one of the user PF received from SC and the device PF received from SC42.

  Note that the content reproduction system 10 transmits the usage device information from the ICC based on at least one of the user PF stored in the ICC and the device PF stored in the SC of the usage device and the movement condition information in the usage right information. The usage right information can be moved up to the SC, or the usage right information can be transferred from the SC of the usage device to the ICC. Similarly, the content reproduction system 10 uses the user device PF stored in the ICC and the device PF stored in the SC of the user device, and the use device from the ICC based on the copy condition information in the usage right information. It is possible to copy the usage right information from the SC to the current SC or the usage right information from the SC to the ICC of the used device. Further, the content reproduction system 10 can transfer the usage right information from the ICC or the SC of the used device to another ICC or the SC of the used device based on the transfer condition information in the usage right information. In other words, the content reproduction system 10 can distribute the usage right information between any ICC such as the ICC 20 and the ICC 120 and any usage equipment such as the usage equipment 40 and the usage equipment 140.

  As described above, the content reproduction system 10 is based on the user PF stored in the ICC, the device PF stored in the utilization device, and the reproduction condition information stored in the ICC or the utilization device. Since it is determined whether or not reproduction is possible, it is possible to reduce the amount of communication between the ICC or the device used and the server 60 when determining whether or not content reproduction is possible.

  In addition, the content playback system 10 determines whether or not content playback is possible based on the user PF stored in the ICC, the device PF stored in the user device, and the playback condition information stored in the ICC or the user device. Therefore, it is possible to prevent the server 60 from grasping what service the user is using, and the privacy of the user can be protected.

  Further, the content reproduction system 10 can store the reproduction condition information in the ICC carried by the user and can move the reproduction condition information together with the user, so that the reproduction condition information cannot be stored in the ICC. In comparison, it is possible for the user to easily change the user device for reproducing the content.

  Further, since the content reproduction system 10 creates reproduction condition information based on the user PF and the device PF that are actually used for determination, reproduction is performed without being based on the user PF and the device PF that are actually used for determination. More appropriate reproduction condition information can be created as compared with the case of creating condition information.

  Further, the content reproduction system 10 can search for content that can be reproduced before the content is reproduced, so that the user can recognize the content that can be reproduced in advance.

  In the content reproduction system 10, the ICC and the SC of the device used constitute a usage right storage unit, but either the ICC or the SC of the device used only has a usage right storage unit. But you can.

  In addition, the content reproduction system 10 includes a reproducibility determination unit as an executable determination unit, but the ICC may include an executable determination unit instead of the usage device. Both of the use devices may have executable determination means.

  In the content reproduction system 10, the used device and the ICC can communicate with each other via an ICC reader / writer built in or external to the used device. However, the used device and the ICC can communicate with each other via a communication path such as the Internet. They may be able to communicate with each other.

  In addition, the content reproduction system 10 includes the ICC as a portable device, but may include a portable device other than the ICC. For example, the content reproduction system 10 may include a mobile phone as a mobile device.

  In the present embodiment, the content reproduction system 10 that executes a service called content reproduction has been described as the service execution system. However, the service execution system may execute a service other than the content reproduction. For example, the service execution system may execute a service that uses information other than content in the service execution device, or may execute a service that uses the service execution device itself.

  For the service execution system to execute a service that uses information other than the content in the service execution device, for example, a network is used from a remote location to a home personal computer (hereinafter referred to as “home PC”) as the service execution device. A file in the home PC can be accessed under the situation that the owner (user) of the home PC can access via the Internet and the home PC owner carries the ICC as a portable device storing the usage right information. That the owner of the home PC uses the right-of-use information in the ICC to execute the service from the outside through the network, or the maintenance target device as a service execution device via the network ) Is accessible, and the ICC as a portable device storing usage right information is maintained. In the context of Nsu worker is portable, there is such as to perform maintenance provider via the network a service of usage of the maintenance information in the maintenance target apparatus by using the usage right information in the ICC.

  In addition, the service execution system executes a service that uses the service execution device itself. For example, an owner (user) of a home PC as a service execution device may use an ICC as a portable device that stores usage right information. Stores the right to access the home PC itself, using the right-of-use information in the ICC, and the right-of-use information to be used by the owner of the home PC from the outside via the network. In a situation where the maintenance company (user) carries the ICC as the portable device, the maintenance company uses the right-of-use information in the ICC to provide a service for accessing the maintenance target device itself as the service execution device. Mobile devices that run through the network or as portable devices carried by visitors (users) In the situation where usage right information is granted at the office of the visited office, the service of opening and closing the office entrance gate itself as a service execution device, and office equipment such as copiers and printing machines as service execution devices There are services in which a visitor executes a service of use of itself or a service of access to a LAN (Local Area Network) in an office as a service execution device by using use right information in a mobile phone.

  In addition to the functions realized by the dedicated equipment, server, and ICC, the program for realizing the functions is recorded on a computer-readable recording medium and recorded on the recording medium. The program may be read by a computer system and executed. The computer-readable recording medium refers to a recording medium such as a floppy disk, a magneto-optical disk, a CD-ROM, or a storage device such as a hard disk device built in the computer system. Furthermore, a computer-readable recording medium is a server that dynamically holds a program (transmission medium or transmission wave) for a short period of time, as in the case of transmitting a program via the Internet, and a server in that case. Some of them hold programs for a certain period of time, such as volatile memory inside computer systems.
