摘要： PROBLEM TO BE SOLVED: To provide a device and a method which prevent the use of unauthorized content and of an unauthorized information storage device.SOLUTION: A system includes: an information storage device; a license authority which generates a media key set (MKS) to be stored in the information storage device; and a content delivery device. Upon production of the information storage device, the license authority obtains and holds a media key binding log which contains: an identifier of the MKS to be stored in the information storage device; and an identifier (IDc) of a controller of the information storage device. In response to reception of content from the content delivery device, the controller of the information storage device outputs the identifier of the MKS and the IDc. The license authority verifies an access log containing the identifier of the MKS and the IDc against the media key binding log, so as to determine validity of the information storage device.
