摘要： To provide a highly user-friendly content moving device which prevents unauthorized copying of content and, when content that has been irreversibly converted and moved to a recording medium is moved back to a move source, can use the content in its form before irreversible conversion. A partial information extraction unit extracts, from content stored on a content storage unit, partial data necessary for playback of the content, and a write/read unit writes the partial data to a partial information storage unit and overwrites a portion of the content corresponding to the partial data with different data, while a conversion unit transcodes the content and writes the transcoded content and the partial data to the recording medium.

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 100, a first information storage unit 102 stores a content, a second information storage unit 103 stores a backup of the content, a secure storage unit 104 stores a hash value of the content. If receiving an instruction to delete the content so as to be restorable, a control unit 113 deletes the content from the first information storage unit 102. When the content is played back, an encryption processing unit 109 applies a calculation to the content to generate detection information, and the control unit 113 compares the hash value with the detection information to judge whether the content has been tampered.

摘要： A data storage apparatus is provided that realizes a measure against deterioration of a flash memory in which integrity check data is stored. A content playback apparatus (1000) uses a hash value of playback history information as integrity check data (confirmation data) for confirming whether the playback history information has been falsified. A first address calculation unit (1004) and a second address calculation unit (1006) determine a read-in address and a storage destination address for the integrity check data, with use of the hash value. Accordingly, the storage destination addresses can be diffused, thus enabling preventing deterioration of the flash memory.

摘要： A program conversion device generates a program by obfuscating an original program, and generates and encrypts conversion parameters for inverse conversion of the obfuscated program. The program conversion device distributes the obfuscated program together with the encrypted conversion parameters. To execute the obfuscated program, a device having a high security level decrypts the encrypted parameters by using a decryption key stored in advance, applies inverse conversion to the obfuscated program by using the decrypted conversion parameters, and executes the program resulting from the inverse conversion. A device having a low security level executes the obfuscated program without any inverse conversion.

摘要： A secure processing device having a power saving mode, which is used for built-in apparatuses, calculates a hash value of secure data that needs to be saved when switching to the power saving mode, stores the calculated hash value in a protection storage unit whose data is not lost even in the power saving mode, encrypts the secure data and stores the encrypted data in an external memory when switching to the power saving mode. When switching back to the normal power mode, the secure processing device decrypts the encrypted data, calculates a hash value of the decrypted data and compares the hash value with the hash value stored in the protection storage unit. The decrypted data is restored to the protection storage unit when the hash values are identical, but discarded together with the encrypted data stored in the external memory when the hash values are not identical.
