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.

There is provided a content use management method capable of preventing unauthorized distribution of a content and improving user-friendliness. In this method, the same group key is stored in a secure device (400) and a playback terminal (500). Moreover, a license issuing application is received from a license distribution server (200) and stored in the secure device (400). After this, a license encrypted by the group key is sent to the playback terminal (500) and the license encrypted by the group key is stored in the playback terminal (500). Upon playback of the encrypted content, the playback terminal (500) decrypts the license by using the group key and acquires the content decryption key, thereby decrypting the encrypted content. Even when the encrypted license flows into the network, it cannot be decrypted by a playback terminal not having the same group key and the copyright is protected. Moreover, the playback terminal (500) which already holds the group key and the license encrypted by the group key does not need the secure device when reproducing the encrypted content.

A data processor includes: a first medium on which a content's data has been bound-recorded; a memory having stored thereon the content's access control information; and a read / write section for reading and writing data from / on a second medium. In response to a request to back up the content, the read / write section writes the content's data on the second medium and the memory retains the access control information without modifying the information. If a request to restore the content has been received and if the access control information that makes the content accessible is stored in the memory and if the content's data has been written on the second medium, then the read / write section reads the content's data from the second medium and writes the data on the first medium.

A copyright of a content is protected by preventing creation of illegal copies of the content and the content is prevented from being transmitted beyond a range of personal use in a process to transmit the content through a LAN. Before transmission of a content, a content transmission apparatus and a content reception apparatus perform a determination of authentication information available in a predetermined command accompanying authentication information, or an authentication determination based on a time until reception of a response to a predetermined command request accompanying predetermined authentication information. If the authentication is unsuccessful, the requested content is not transmitted to the content reception apparatus. With such arrangement, it is possible to effectively protect a copyright when a content is transmitted by way of a network.

It is an object of the present invention to protect a copyright of a content by suppressing creation of illegal copies of the content and prevent a content from being transmitted beyond a range of personal use in a process to transmit the content through a wire or wireless LAN. Before transmitting a content from a content transmission apparatus to a content reception apparatus, the content transmission apparatus and the content reception apparatus authenticate each other. In the authentication, a timer measures a time interval between a transmission of an authentication request and a reception of an acknowledgement of a reception of the request or between a transmission of a response to a received authentication request and a reception of an acknowledgement of a reception of the response. If the time interval does not exceed an upper limit, a content encrypted by using a shared key is transmitted from the content transmission apparatus to the content reception apparatus, and the address of the content reception apparatus as well as apparatus information unique to the content reception apparatus are cataloged in the content transmission apparatus. Thus, in order to transmit another content, the content is merely encrypted prior to the transmission without measuring a time interval.

A recorder is composed of a drive 102 and a host 103 that mutually authenticate each other. A C2_G 141 of the drive 102 calculates a medium ID and a medium key and obtains a medium unique key. The medium unique key is encrypted using a session key Ks generated by the mutual authentication and transferred to the host 103. A title key generated by a random number generator 143 of the drive 102 is transferred to the host 103. A content key calculated by a C2_G 145 of the drive 102 using the title key and the CCI 232 is encrypted using the session key Ks and then transferred to the host 103. A content is encrypted using a content key decrypted by the host 103. The drive 102 records the encrypted content, the encrypted title key, and the CCI 232 to the medium 101.
