    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: Spread of a forged storage medium is prevented suppressing an authentic storage medium's damage and trouble of a owner to the minimum. When there is an update request of user key data, the update history of the user key data concerning the shown above-mentioned medium identifier IDm is referred to. When judged that the update of the user key data concerning the shown medium identifier IDm not being performed within a predetermined period, the update of user key data is performed. The request of a update is refused when judged that the update of the user key data concerning the shown medium identifier IDm being performed within a predetermined period.

    摘要: A handheld device is configured to be connectable to a storage media that holds a unique media identifier and holds a content key data used to decrypt an encrypted content data. A content data delivery system is provided that is configured to be able to deliver various data to the handheld device and to make a content data available to the handheld device. The system includes a member-registration information database that holds member-registration information including a data pair of a handheld-device identifier related to the relevant handheld device and the relevant media identifier. The media identifier held by the storage media is verified with the member-registration information database.

A content data delivery system is provided that is configured to be able to deliver various data to the handheld device and to make a content data available to the handheld device. The system includes a member-registration information database that holds member-registration information including a data pair of a handheld-device identifier related to the relevant handheld device and the relevant media identifier. The media identifier held by the storage media is verified with the member-registration information database. When it is determined that the media identifier corresponds to the member-registration information, the content key data held in the storage media is read, and it is determined whether an encrypted content data corresponding to the read content key data is stored in the storage media or other storage media coupled to the storage media. The encrypted content data is transferred to the storage media or the like depending on the user's specification.

    摘要: A system for providing program information has a user terminal, a recording medium capable of reading information therefrom and writing information thereto through a command issued by the user terminal, and a server connected to the user terminal via a network, and provides program information from the server to the recording medium. The recording medium has a first control unit that performs a first mutual authentication operation with a first storage unit capable of writing program information thereto and the user terminal, and that executes a command to write program information to the first storage unit only if the first mutual authentication operation is successful. The user terminal performs a second mutual authentication operation with the server, obtains program information transmitted from the server if the second mutual authentication operation is successful, and issues a command to write the program information to the first storage unit of the recording medium.

    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.

    摘要: A content distribution method distributes a package containing a content from a content distribution apparatus to a terminal of a content distribution destination and causes the terminal to expand and display the content contained in the distributed package by using expansion software provided in the terminal. Update data of the expansion software is inserted in the package in addition to the content. When the terminal cannot expand the content by using the expansion software provided in it, the terminal updates the expansion software provided in it by using the update data contained in the distributed package and expands the content by using the updated expansion software.
