    摘要: A method of delivering content data is provided that makes content data able to be reproduced at a user terminal by delivering content key data necessary to decrypt the content data. Specifically, portable storage media storing in advance the content data encrypted with the content key data is connected to the user terminal having a unique terminal ID. User key data that is provided with a predetermined expiration date and is necessary to encrypt the content key data is transmitted from a server to the user terminal. The user key data is stored in an internal memory in the user terminal in such a way that the user key data is unable to be read out of the internal memory. The content key data necessary to decrypt the content data stored in the portable storage media is encrypted with the user key data, and the encrypted content key data is stored in the user terminal or the portable storage media.

    摘要: One aspect of the present invention is to provide a login system and method which can be easily applied to corporate members, and which can prevent unauthorized use even if authentication information is copied. Because of a configuration in which login is carried out by using service right data for each medium identifier of a secure storage medium, unless a dishonest person uses the secure storage medium, it is impossible to log in even if the dishonest person copies authentication information. Further, provided that the secure storage medium is distributed to every signal person belonging to a corporate body, it can be applied to corporate users in the same way as individual users.

    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.

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.
