Data management system

Abstract

A system for dealing in an original data content and an edited data content. A data content is handled as an object, and the data content is edited by editing a data content, functioning as an object, in accordance with an edit program. The edited data content is expressed by the original data content and the editing scenario which describes editing detail by the edit program. Only the encrypted editing scenario is dealt in. Upon receipt of the encrypted editing scenario, a user decrypts the encrypted editing scenario using a crypt key obtained from a key management center, and obtains the original data content from the database in accordance with the editing scenario and re-constitutes the edited data content. In case there is the one who wishes sale of the editing scenario, its utilization right is sold by auction.
