摘要

An electronic copyrighted work distribution management system includes an electronic copyrighted work sales apparatus (1) selling an electronic copyrighted work, a copyright management apparatus (4) administering a copyright royalty of an electronic copyrighted work sold by the electronic copyrighted work sales apparatus (1), a seller terminal (5) used by a seller, and a copyright terminal (7) used by a copyright holder. The electronic copyrighted work sales apparatus (1) calculates and transmits to the copyright management apparatus (4) the copyright royalty of a selected electronic copyrighted work. The copyright management apparatus (4) stores the received copyright royalty data for each copyright holder. Since the copyright management apparatus (4) receives and stores for each copyright holder the copyright royalty data transmitted from the electronic copyrighted work sales apparatus (1), the copyright royalty can be administered.
