摘要： The operating and other procedures of an optical disk application system of the type for which a netwcrk is used are simplified. Optical disks have auxiliary data recording areas, where different IDs for individual disks, and/or cipher keys and/or decoding keys for ciphers are recorded in advance in a factory. By using the IDs to release the soft ciphers, using the cipher keys when sending the ciphers, and using the decoding keys when receiving the ciphers, user authorization procedures are simplified.

摘要： For an encrypted content (104) stored in a content accumulation medium (102), small-data-amount information on the encrypted content (104) is stored in the content accumulation medium (102) in correlation to the encrypted content (104). Thus, without decrypting the large-data-amount encrypted content (104), it is possible to judge the encrypted content (104) according to the small-data-amount information. This enables a user to easily judge a plurality of contents stored in the content accumulation medium.

摘要： With respect to encrypted content 104 stored in content storage medium 102, by storing information with a small data amount related to the encrypted content 104 in content storage medium 102 in association with the encrypted content 104, it is possible to distinguish between encrypted content 104 based on the related information without decoding the encrypted content 104 with a large data amount. It is thereby possible to more readily distinguish between a plurality of pieces of content stored in the content storage medium.

摘要： A copy protection program (104) for securely holding digital audio and/or video content is bound to a particular device (100) via a key (200) derived in part (201) from unique or distinctive hardware, software and/or firmware identifiers within the device and in part (202) from a random or pseudo-random number. The key (200) is checked or rebuilt whenever the copy protection program (104) is employed to access protected digital content, either authorizing/prohibiting such access to the content or enabling/precluding proper decoding of the content. Therefore the digital content need not be directly bound to the device (100) while circumvention of the copy protection is frustrated.

摘要： An information recording or reproducing device in which key distribution is effected by KRB distribution as a key distributing configuration of a tree structure. In this information recording or reproducing device, a key, such as a master key, a media key or a content key, is transmitted along with the KRB (key renewal block) by the key distributing configuration of the tree structure. After a given recording and/or reproducing device has acquired a key of a given recording medium on calculations, based on the KRB as received, the so acquired key is encrypted with a cipher key unique to the recording or reproducing device, such as a leaf key, so as to be then stored in a recording medium or in a memory of the recording or reproducing device. Thus, when the recording and/or reproducing device next uses the recording medium or the content, the recording or reproducing device is able to calculate the key on decrypting the cipher key only once. So, the volume of processing such as KRB decrypting processing needed when the recording and/or reproducing device accesses a recording medium or uses the content may be diminished to improve the efficiency in the processing on the KRB receipt side.

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.
