    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.

    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 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.

    摘要: There is provided a content data reproducing system that allows, in a user terminal adapted to be able to read a recording medium storing a content data encrypted with a predetermined encrypted key data, the content data to be reproduced after a CM data is reproduced. The system includes a CM data transmission portion that transmits the CM data to the user terminal in response to a request from the user terminal. When the sensing portion senses that the reproducing of the CM data has been completed in the user terminal, a permission portion permits the user terminal to use the encrypted key data to decrypt and reproducing the content data.

    摘要: This data protection system encrypts and stores data in a memory card, using a double encryption key scheme for encrypting the data with a data key and further encrypting the data key with a user key. This system provides data to a particular host device from the memory card and limits provision of the data to other host devices. The host device includes DPS program that governs control of writing data to, and reading data from the memory card. The memory card includes a first non-volatile memory and a memory controller that controls the first non-volatile memory. DPSA program is implemented in the memory controller that manages ID information for identifying a user capable of decrypting the encrypted data with the user key.

    摘要: An interface control device includes a first interface, a second interface, a third interface, an interface controller and a clock supplying unit. The first interface is used to communicate with a first information processing device and obtain a first clock signal from the first information processing device. The second interface is used to communicate using a second clock signal with a second information processing device different from the first information processing device. The third interface is used to communicate with a controller of a data-storage medium. The interface controller performs an interface control for the first, second and third interfaces. Moreover, the clock supplying unit supplies the first clock signal to the third interface while communications through the second interface have not been established.
