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： A copyright protection system includes a recording device and a reproduction device. The recording device writes encrypted content, an encrypted content key for decrypting the encrypted content, and license information on a recording medium on which a unique media number has been recorded in an unrewritable state. The license information is generated using both the media number and the encrypted content key, and therefore reflects both values. The reproduction device reads the media number, the encrypted content key, and the license information from the recording medium, and judges whether the license information reflects both the media number and the encrypted content key. The reproduction device decrypts the encrypted content key, and decrypts the encrypted content using the content key only if the license information reflects both values. Thus, the copyright protection system allows only original recording media to be reproduced, and prohibits reproduction of copy recording media.
摘要翻译：版权保护系统包括记录装置和再现装置。记录装置将加密内容，用于解密加密内容的加密内容密钥以及在不可重写状态下记录了唯一媒体号码的记录介质上的许可信息进行写入。使用媒体号和加密的内容密钥来生成许可信息，因此反映这两个值。再现装置从记录介质读取媒体号码，加密的内容密钥和许可信息，并且判断许可信息是否同时反映媒体号和加密的内容密钥。再现设备解密加密的内容密钥，并且仅在许可信息反映这两个值时才使用内容密钥来解密加密的内容。因此，版权保护系统仅允许再现原始记录介质，并且禁止复制记录介质的再现。

摘要： With content management apparatus 110 serving as a copy origin and storage medium 120 as a copy target, the copy origin retains allowed copy count control information on content, and when the content is copied from the copy origin to the copy target, the allowed copy count control information retained at the copy origin before copy processing is updated in accordance with a predetermined rule to generate allowed copy count control information to be retained at the copy origin and allowed copy count control information to be retained at the copy target, and subsequent copy processing at the copy origin is done based on the allowed copy count control information retained at the copy origin, whereas subsequent copy processing on the content stored in storage medium 120 is done based on the allowed copy count control information stored in storage medium 120. In this way, it is possible to achieve content management which is easily understandable for users.

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 content of Copy Once cannot be copied to an external device or the like, even for the purpose of making a backup. This is inconvenient for the user. However, if copying to another device for the purpose of making a backup is permitted, the content may be copied in an unauthorized manner. The present invention provides the hard disk recorder 100 that transmits the content to the backup device 500, sets an expiration time in the content stored in the hard disk recorder 100 itself, and deletes the content stored in the hard disk recorder 100 itself after the expiration time expires.

摘要： The media inherent key storing unit 220 prestores an inherent key Ki, the conversion unit 230 generates an encrypted inherent key Ji from the inherent key read from the media inherent key storing unit 220, the random number generating unit 331 generates a random number R1, the encryption unit 252 generates an encrypted random number S1, the decryption unit 333 generates a random number R′1 from the encrypted random number R1, and the mutual authentication control unit 334 compares the random number R′1 with the random number R1 and, if the random number R′1 matches the random number R1, judges that the memory card 200 is an authorized device. If the memory card 200 and the memory card writer have successfully authenticated each other, the memory card writer encrypts a content using a decrypted inherent key. If the memory card 200 and the memory card reader have successfully authenticated each other, the memory card reader decrypts an encrypted content using the decrypted inherent key.
