Abstract If a recording medium having a medium ID is used, a secure manager manages enciphering/decoding of a content with use of the medium ID for each recording medium. If a HDD having no medium ID is used, the secure manager obtains a device ID specific to a computer system through a BIOS and manages enciphering/decoding of a content to be recorded into the HDD, with use of the device ID. The device ID is stored in a safe area in the computer system. As a result, even if a content is recorded into an open recording medium such as a hard disk drive, the content can be protected from improper use so that utility and protection of digital contents can be improved.
