    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 protection system prevents illegal key acquisition, without checking uniqueness of device keys. The content protection system includes a key data generation apparatus and a user terminal. The key data generation apparatus converts first key data, which is for using content, based on a predetermined conversion rule, thereby generating second key data, encrypts the second key data using a device key held by valid terminals, and outputs the encrypted key data. The user terminal obtains the encrypted key data, decrypts the encrypted key data using a device key held by the user terminal, thereby generating second key data, converts the second key data based on a re-conversion rule corresponding to the conversion rule, thereby generating the first key data, and uses the content with use of the generated first key data.

    摘要: To provide a backup management device that deletes a content so as to be restorable in the future while protecting a copyright of the content, in a case where there exists a backup of the content. In an HD recorder, a first information storage unit stores a content, a second information storage unit stores a backup of the content, a secure storage unit stores a hash value of the content. If receiving an instruction to delete the content so as to be restorable, a control unit deletes the content from the first information storage unit. When the content is played back, an encryption processing unit applies a calculation to the content to generate detection information, and the control unit compares the hash value with the detection information to judge whether the content has been tampered.
