Even if contents data distributed over a network are once destroyed, the contents data are restored, as the copyright protection is maintained. A PC memorizes backup of distributed music contents on a hard disc, at the same time as it transmits the using log information of the music contents stored in the hard disc to an EMD server. If the music contents in the hard disc are destroyed, the PC acquires the using log information from the EMD server to reproduce the backup data memorized in the hard disc depending on the using log information.

After a reproduction program is installed on a PC, a key for CD ripping is furnished e.g., from an FD. With the key for CD ripping, the music contents in a CD can be copied to a PC, however, it is not possible to download music contents from an EMD server for copying on a PD. For storing the music contents distributed from the EMD server on the PD, the reproduction program first acquired a key for EMD different from the key for ripping over the network. By so doing, the contents data distributed over the network may be improved in safety.

A content sharing system is disclosed that can efficiently execute copyright management and can promote the degree of freedom and convenience in sharing of content within a legal range of private utilization. A group management server places a plurality of content processing apparatuses in terms of a unit of an owner into a group registration and issues a notification of a group ID of the group. A content recording apparatus adds a recorder ID thereof to production content produced thereby. Further, a content reproduction apparatus controls reproduction of content based on a recorder ID read out from content and a reproduction permission ID list. If the different processing apparatuses have the same group ID, the recorder ID can be added to the reproduction permission ID list.
摘要:
A content sharing system is disclosed that can efficiently execute copyright management for limiting illegal utilization of content, and can promote the degree of freedom in utilization of content within a legal range of private utilization. In the content sharing system, a content processing apparatus on the content providing side includes a source ID addition section for adding, to the content data, a source ID for specifying a providing source of content data. Meanwhile, another content processing apparatus on the content acquiring side includes a content rendering section having a rendering permission ID list including source IDs, added to content data whose rendering is permitted, for limiting, based on the source ID added to the acquired content data and the rendering permission ID list, rendering of acquired content data rendering. The content sharing system further includes a list management section for permitting updating of the rendering permission ID list.
