  • Patent number: 7861284
    Abstract: An authentication information and a verification information are previously generated and the authentication information is stored to an authentication data generating apparatus, while the verification information is stored to a gateway. When a controller tries to make communication With a customer premises apparatus, the authentication data generating apparatus connected to the controller generates an authentication data using the authentication information and the gateway verifies the authentication data using the verification information. Moreover, the gateway restricts, when connected to the authentication data generating apparatus, the communication between the controller located in the outside of customer premises and the customer premises apparatus. Moreover, the gateway changes, while connected to the authentication data generating apparatus, an address of the customer premises apparatus and stores the changed address to the authentication data generating apparatus.

  • Patent number: 7275687
    Abstract: A delivery service providing system includes an entrance and exit control unit, an identifier control unit, and a delivery service providing unit. The entrance and exit control unit inputs a ticket identifier of a user who has entered or exited a predetermined area and transmits the identifier to the identifier control unit. The identifier control unit registers the ticket identifier to a database and erases the ticket in case of exit. The identifier control unit receives an identifier set of a ticket identifier and a user's unit identifier from a user's unit, checks to judge whether an identifier set matching the received identifier set in the database. If the result is positive, the delivery service providing unit delivers digital contents to the user's unit. It then becomes possible to provide only the users existing in the area with the contents deliver service.
