A pay television IC card includes a storage unit prestoring fingerprint information that allows identification of a registrant, a fingerprint information input unit accepting input of physical description data of a user, a comparison determination unit comparing fingerprint information accepted by the fingerprint information input unit with fingerprint information stored in the storage unit to determine whether the user is the registrant, and a descramble key generation unit providing a descramble key based on the determination result by the comparison determination unit. A descramble key is output by determining whether the user and the registrant are the same person based on fingerprint information, and determination of the sameness between the user and the registrant is established.
