Abstract
A right management server manages usage of a content on a parent terminal and a child terminal. The right management server includes content usage right database that stores right information indicating a usage rule of a content for each terminal ID or user ID, and a parental control information management unit that acquires, from the parent terminal or the parent user, parental control information that is an instruction to put a restriction on usage of a content on the child terminal or by a child user, and stores the parental control information in a parental control information database. The right management server also includes a license ticket generation unit that acquires a license ticket issuance request from the child terminal or the child user, generates a license ticket that is information for permitting usage of the content on the child terminal or by the child user, under a usage rule with a restriction indicated by the parental control information which is held in the parental control information management unit, and sends the license ticket to the child terminal or the child user.
