摘要： To exclude any unauthorized device from a system and thereby prevent illegal use of content data, a memory card 10 stores a service key Ksrv for encrypting content key data Kc in a hidden area 14. The memory card 10 stores answer data ACto be obtained when question data Q is fed to a host function F possessed by an authorized host device 20, with encryption applied to the answer data AC by the service key Ksrv. When the question data Q is provided to the host device 20, answer data AH is obtained based on the question data Q and the host function F. A comparison unit 122 judges match or mismatch of the answer data AH and the answer data AC. When they match, the memory card 10 decrypts the content key data Kc encrypted by the service key Ksrv and sends it to the host device 20.

摘要： A personal computer PC transmits to a server encoded user information and encoded license information, etc. contained in a secure recording medium. The server decodes the encoded license information to obtain license information. Then, the server deletes the encoded license information contained in the secure recording medium via the personal computer PC. The server decodes the decoded user information contained in a secure recording medium to obtain user information. Then, the server encodes the license information based on the user information to write the obtained encoded license information into the secure recording medium via the personal computer PC. In this manner, license information can be moved between two secure media and convenience can be improved.
