Abstract: A configuration is achieved in which content copying between media and content downloading are performed effectively and under strict management. In content copying between media, the identification information (medium ID) of a copying destination medium is obtained using an API for providing a predefined processing, then the obtained medium ID is transmitted to a server to obtain copying permission information from the server, and then content copying is performed under the management of the server. This configuration allows a copying destination medium to be managed, which can eliminate the unauthorized use of the content. Also, the configuration in which content downloading from the server is performed according to, for example, a Java® program allows a ROM disc on which the content is recorded to store the program and to be provided to a user.

Abstract: A terminal stores in a storage section content distributed from a server and a data access power for deleting a service that differ from a service to which the content belongs in association with each other. The terminal determines, when the stored content requests the deletion of the differing service that is indicated by the statement contained in the content, whether or not the content and the data access power are stored in the storage section in association with each other. When the terminal has determined that the content that requested the deletion of the differing service and the data access power are stored in the storage section in association with each other, the terminal deletes content that belongs to the differing service from the storage section.
