  • Patent number: 12216748
    Abstract: An authentication device includes a comparison unit and a determination unit. The comparison unit compares, with feature value master data for authentication, each feature value needed for authentication that has been extracted from a plurality of pieces of acquired biometric information. The determination unit determines not to provide authentication when, as a result of comparison by the comparison unit, there is no difference in each of the feature values that resulted in a mismatch.

  • Patent number: 11240161
    Abstract: A data communication apparatus is provided that includes: a transmission-reception part configured to transmit and receive data between a client terminal and a server, an ABR determination part configured to determine whether or not a data transmission scheme from the server to the client terminal is based on an ABR (Adaptive Bit Rate) distribution scheme, and, a scheme determination part configured to determine the data transmission scheme upon transmitting a received data from the server to the client terminal according to a result by the ABR determination part, wherein the transmission-reception part is configured to transmit the received data from the server to the client by the data transmission scheme determined by the scheme determination part.

  • Patent number: 10897416
    Abstract: A transmitting side device generates a plurality of measurement packets of which the packet size is successively increased or decreased by a fixed number each time, includes in each measurement packet at least a packet number, a packet size, and a transmission time, to create a packet train, and transmits the packet train at predetermined equal intervals. A receiving side device measures the time of arrival of each of the measurement packets constituting the packet train, and extracts as a valid packet a series of measurement packets at a location where a change in the measured time of arrival matches an arrival time change model having a predetermined pattern. A network available band is computed using a measurement packet, among a series of measurement packets having equal arrival times, that has a maximum packet size.

  • Patent number: 10674392
    Abstract: A reception unit 11 receives transmitted packets. A first available band calculation unit 12 and a second available band calculation unit 13 calculate an available band for a transmission source of the packets. A calculation means determination unit 14 determines, on the basis of the reception states of the packets transmitted at predetermined time intervals in the reception unit 11, whether the first available band calculation unit 12 calculates the available band or the second available band calculation unit 13 calculates the available band. The first available band calculation unit 12 calculates the available band on the basis of a reception interval between the packets. The second available band calculation unit 13 calculates the available band on the basis of a time required for the reception of the transmitted series of packets and the sizes of the series of the packets.
