摘要： A server apparatus encrypts content, based on a distribution key, and transmits the encrypted content to a PC via a network. The PC, to which a memory card is connected, outputs the received encrypted content to the memory card. The memory card decrypts the encrypted content using the distribution key, converts the data format of the decrypted content, encrypts the content using a medium unique key that is unique to the memory card, and records the resulting re-encrypted content internally. A playback apparatus decrypts the re-encrypted content using the medium unique key, and plays back the decrypted content.

摘要： A content management system formed from a playback apparatus that requests and plays content, and a content management apparatus that manages duplication and deletion of content. The playback apparatus notifies group information of the playback apparatus to the content management apparatus, acquires information from the content management apparatus showing whether requests are permitted, and duplicates/deletes content. By judging whether the playback apparatus belongs to a group, and notifying whether a duplication request is permitted or rejected, based on in-group and out-group remaining numbers that show the remaining number of duplications permitted of apparatuses in-group and out-group, respectively, the content management apparatus relaxes restrictions on in-group content duplication as compared with out-group content duplication, and thus improves convenience for users in a home network, while protecting the rights of copyright holders, with respect to content duplication and usage.

摘要： A key delivery apparatus that prevents improper use of contents, and manages a decryption key for decrypting encrypted content and a suppliable number showing how many times the decryption key is suppliable, with respect to one or more terminal apparatuses connected to a network. The key delivery apparatus receives a supply request for the decryption key from a terminal apparatus, and if the terminal apparatus is a legitimate supply target, judges whether the terminal apparatus is a first-type that manages a content-usage period or a second-type that does not manage the content-usage period, and if the suppliable number has a remaining number, supplies to the terminal apparatus, the decryption key and a key-usage period of the decryption key when judged that the terminal apparatus is the first-type and the decryption key when judged that the terminal apparatus is the second-type.

摘要： Disclosed is a digital work protection system enabling a content distributor to flexibly define usage patterns of content permitted for users. The system is composed of a recording device and a playback device. The recording device acquires a digital work, range information showing a permission range within which the digital work is permitted to be used, and a subrange key for each subrange, generates an encryption key using all the acquired subrange keys, encrypts the digital work based on the encryption key to generate encryption information, and writes the encryption information and the range information to a recording medium. The playback device reads the range information and the encrypted information from the recording medium, acquires a subrange key for each subrange, generates a decryption key using all the acquired subrange keys, decrypts the encrypted information based on the decryption key to generate a digital work, and plays the digital work.
