    Abstract: PROBLEM TO BE SOLVED: To promote utilization of a communication line by calculating a reasonable communications charge to be charged on each user, when secondary utilization of the communication line to be offered as communication service is permitted. SOLUTION: A communication relay system 20 is provided for offering communication service for connecting a communication device to an existing communication network. The relay system 20 includes a communication relay 200 which relays communication between the communication network and a primary communication device which is connected to a predetermined primary communication line and is used by a contractor, by connecting the primary communication device 30 to the communication network; an account DB 25 for recording a communication charge to be charged for communication of the primary communication device with the communication relay system via the primary communication line; and a charger 260 which reduces the amount of the communication charge recorded on the account DB 25, on condition that another contractor connects a secondary communication device to the primary communication device, and connects it to the communication network via the primary communication line in the relay 200.

    Abstract: PROBLEM TO BE SOLVED: To provide a device establishing encryption communication to a communication apparatus for performing power line transmission by a simpler operation than before.
    SOLUTION: The device according to the present invention performs transmission setting for a first and a second communication systems having a function to superimpose a transmission signal on an electric power signal for communications. The device comprises: a power receiving plug for receiving electric power via an external power supply socket; at least one power supply socket for supplying the electric power received via the power receiving plug to the first and the second communication systems, a signal filter for shutting off a transmission signal propagating a power line between the power receiving plug and the power supply socket; an encryption key acquiring portion for acquiring an encryption key used for encryption communication between the first and the second communication systems or authentication from the first communication system connected to the power supply socket; and an encryption key transmitting portion for transmitting the encryption key acquired by the encryption key acquiring portion to the second communication system connected to the power supply socket.

    Abstract: PROBLEM TO BE SOLVED: To detect a watermark image described in a printed matter at precision higher than in the conventional case and to display the watermark image so that it is easy to make a user recognize it. SOLUTION: This display device which extracts and displays the watermark image described in an object to be photographed is provided. The display device is provided with a first photography part which generates a first image by photographing the object to be photographed, a second photography part which generates a second image by photographing the object to be photographed including a watermark image preliminarily described in the object to be photographed and which is not detected by photography of the first photography part and a watermark image extraction part which extracts the watermark image from the second image based on the first and second images.
