摘要： This invention provides a license information management apparatus and the like that do not require a tamper resistance module with a large memory even in the case where a user possesses a large amount of content. A total control unit (113) specifies a content corresponding to a reproduction instruction received from a user (S202). Further, the total control unit (113) verifies whether or not there is a LT corresponding to the specified content in a secure flash unit (120). In the case where there is the LT in the secure flash unit (120) (S203: Yes) and information concerning the reproduction of the content is received from the content decryption unit (520) (S204: Yes), an encryption/decryption unit (114) decrypts the LT stored in the secure flash unit (120) using a TRM unique key (S205). After that, the encryption/decryption unit (114) updates details of the content reproduction condition information (511a), encrypts the updated details using the TRM unique key, and writes the encrypted TRM unique key into the secure flash unit (120) (S208).

摘要： To provide a content playback device that can use content appropriately by avoiding output of content not permitted to be used according to contract information. A playback control unit 102 extracts a content name from playback control information in a playback path information table 210, and inquires of a rights management unit 108 whether content identified by the extracted content name is playable or not. If the content is judged as being unplayable, the playback control unit 102 extracts an alternative playback number from the playback control information, and extracts a content name from playback control information whose playback number matches the alternative playback number. The playback control unit 102 then instructs a decryption unit 103 and a playback unit 107 to decrypt and play back encrypted content identified by the extracted content name.

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 soldposs ible after the speci f ic server breaks down. Akeyacquisition 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.
