RECORDING MEDIUM, MANUFACTURING METHOD THEREOF, REPRODUCTION METHOD, REPRODUCTION DEVICE, AND COPYRIGHT MANAGEMENT METHOD

摘要

A GUID as title information and a global serial number are recorded on a BCA of a digital video disc (60) and a Hash value of the GUID is embedded as a watermark in a data area (64). Upon reproduction, check is made whether these two GUID information coincide, thereby preventing unauthorized copying. A disc revocation list is provided from a lead in area (63) and a management mechanism (20). By using the global serial number and the disc revocation list, it is possible to exclude an unauthorized disc. Data embedded in a film to be screened is detected by a film WM detector (84) so as to exclude a disc containing the data. Thus, it is possible to exclude a disc distributed in an unauthorized manner before being allowed by the copyright manager.
