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： 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： A recording device which backs up a content α in a recording medium and a recording device which restores the content are registered in a server so as to belong to the same domain group. When the recording device tries to restore the content, the restore is permitted only when both the recording devices belong to the same domain group. When there is a refresh request of the domain group, the domain group is invalidated only when a refresh period has passed. When a refresh number recorded in the recording device is less than or equal to the refresh number recorded in the recording device, the recording device backs up and locally merges the content recorded in the recording device into the recording medium.
