  • Patent number: 9152770
    Abstract: A content reproduction system includes an information processing terminal and a secure device. The information processing terminal receives a copyright protection application program from an application distribution server. The copyright protection application program includes a first program having a first execution format executable in the information processing terminal and a second program having a second execution format different from the first execution format and executable in the secure device. The second program is encrypted with a program key held in the secure device. By extracting and executing the first program, the information processing terminal extracts the second program and transmits the second program to the secure device. The secure device receives the second program from the information processing terminal, decrypts the second program using a program key stored in a key storing unit, and executes the second program.

  • Patent number: 9130741
    Abstract: A data protection system includes terminals, and an encryption device that encrypts distribution data distributed to each terminal. Each terminal corresponds with one node on a lowest level of a tree structure having hierarchies. A data protection system excludes nodes on the lowest level, determines a plurality of combination patterns that include combinations of two or more of all four nodes that are reached one level below the node, decides an individual decryption key for each determined combination pattern, and decides an individual decryption key for each node on the lowest level. The data protection system prescribes nodes that are reached from the node on the lowest level and a terminal to the node on the highest level that is an invalid node.

  • Publication number: 20140344054
    Abstract: A first user among a plurality of users is associated with a second user having an evaluation tendency similar to evaluation data of the first user for management. Further, a third user is selected by a terminal device of the first user as a user having preference information that suits preference of the first user. The third user is associated with the first user and the second user for management. This configuration makes it possible to select not only a user automatically selected by a system but also another user whom a targeted user is interested in as a similar user, allowing provision of information that better suits hobby and preference of the targeted user.
