    摘要: An ID (MID) is attached to each individual optical disk, and content is encrypted with a Content-Key and registered. In addition, a system server device maintains a Client ID of a client terminal device, HDD-ID of a hard disk drive (HDD), and MC-ID of a memory card respectively held as user entry information. When the user wants to copy the content, together with the optical disk MID, the MC-ID is sent to the system server side. The system server device identifies the user by referencing the MC-ID in the user entry information, and returns a Content-Key, which is used when encoding content. On the user side, content stored in the optical disk is decrypted using the returned Content-Key and copied to the HDD. Accordingly, copying of content is allowed only for an authorized user who is the lawful owner of the storage media.

    摘要: A digital contents distribution system has a multi-layered structure including a server device (CS device) of one or a small number of managers which are each to be a manager main body, a plurality of server devices (DS devices) of middle managers, and client terminal devices (SC terminal devices) of a large number of users. Accesses from the respective users are processed in the server devices of respective ones of the middle managers. It is therefore possible to prevent an inconvenience in which the accesses from a large number of users concentrate on the CS device of the manager. As a result, it is possible to reduce the load imposed on the CS device, and to perform a smooth distribution service of digital contents.
