摘要 |
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.
