  • Content distribution system and content distribution method
    Patent number: 8401909
    Abstract: A content distribution system which assures reliability of content is provided. Permitted-user information corresponding to a user who is permitted to use content to be distributed is associated with the content. In the case where user specific information which specifies a user and the permitted-user information do not have a predetermined relation, a user terminal transmits the user specific information and the permitted-user information to a server. The server generates user-related information in which the received user specific information is set as a distribution destination and the permitted-user information is set as a distributor, generates new permitted-user information so as to have the predetermined relation with the user specific information, and provides the new permitted-user information to the user terminal. The user terminal which obtains the new permitted-user information changes the permitted-user information to the new permitted-user information.
