摘要： A content playback apparatus reduces load concentration on a specific server apparatus that manages content keys of encrypted content, while protecting copyrights of the content. The content apparatus makes playback of content recorded in a recording medium sold possible after the specific server breaks down. A key acquisition control unit (204) reads a playback control information table (211) from a recording medium (102) via a reading unit (201). The key acquisition unit (204) acquires a rights key via a key acquisition intermediation unit (223) from an apparatus specified by an acquisition-destination type and a request-destination type that are stored in the playback control information table (211) and that corresponding to the content to be played. The key acquisition unit (204) generates a content key using the acquired rights key and, when required, a medium key recorded in a medium. A decryption unit (203) decrypts encrypted content using the content key.

摘要： Provided is an information recording medium (104) on which a first content and a program are recorded. A reproreproduction apparatus (1) includes: a first storage unit (221) in which a setting value set is stored; an execution unit (206) which executes the program; and a second storage unit (222) which the execution unit (206) can read and write information from/into. The program causes the execution unit (206) to execute steps of: writing (S803) the setting value stored in the first storage unit (221) into the second storage unit (222); comparing (S900) the setting value stored in the first storage unit (221) to the setting value which has been written into the second storage unit (222); and controlling (S920) the reproduction apparatus not to reproduce the first content, in the case where the comparing (S900) indicates that the setting value stored in the first storage unit (221) is different from the setting value which has been written into the second storage unit (222).

摘要： A data communication unit receives encrypted digital data via a network and records the digital data on a primary recording medium. The digital data, having been encrypted in different encryption methods according to the distributors, include attribute information indicating the encryption methods. The encryption method of the digital data is determined and the encrypted data is decrypted by an appropriate decryption unit. Identification information of a secondary recording medium or a playback apparatus is obtained according to whether the secondary recording medium is removable from the playback apparatus. A controller selects an encryption unit among a plurality of encryption units according to the obtained identification information. The selected encryption unit creates an encryption key according to the identification information and re-encrypts the digital data. A recording unit records the digital data on the secondary recording medium. An accounting unit charges according to accounting information in the attribute information.

摘要： The playback apparatus of the present invention is able to judge whether a region code assigned to a BD-ROM matches a region code assigned to the playback apparatus. When the judgment result is in the affirmative, the playback apparatus plays back the content recorded on the optical disc. When the judgment result is in the negative, the playback apparatus does not play back the content, except when an exceptional playback is authorized. The exceptional playback is authorized when a combination of the content identifier of the content to be played back and the apparatus region code satisfies a predetermined condition defined by a right owner of the content.
