A data processing system includes an event information generating apparatus including generation means that receives data collected from a plurality of terminals, generates event information from the data, and transmits the generated event information to a broker device. The event information generating apparatus includes transmission means that transmits, to a data hub node device corresponding to the event information generated by the generation means, among a plurality of data hub node devices that differ for each event information, data corresponding to the event information. The data processing system includes a data processing apparatus including acquisition means that acquires event information corresponding to a specific service from a broker device. The data processing apparatus includes processing means that acquires the data from a data hub node device that stores the data corresponding to the event information, to execute processing using the data.

An information communication apparatus, which aggregates data transmitted from a plurality of terminals and transmits the aggregated data to a reception side. The information communication apparatus includes: a determination means that operates in a first layer for determining an update size of a memory area used to hold the data transmitted from the plurality of terminals on a basis of information related to the data; and a setting means that sets a band of a network path of a second layer necessary for communicating with the reception side on a basis of the update size and an update rate of the data.

An address allocated to a user by an authentication server is used as an IP address of a packet which is transmitted from a user terminal, preventing an illicit use if the IP address were eavesdropped. An authentication serverperforms an authentication of a user based on a user authentication information which is transmitted from the user terminal, and upon a successful authentication, allocates an address to the user terminal, and issues a ticket containing the address to be returned to the user terminal. The user terminal sets up the address contained in the ticket as a source address, and transmits the ticket to the application server, requesting a session to be established. After verifying that the ticket is authentic, the serverstores the ticket and establishes a session with the user terminal. The user terminal transmits a service request packet containing the source address to the serverutilizing the session. If the source address coincides with the address contained in the stored ticket, the serverprovides a service to the user.

User authentication system for providing online services based on the transmission address

The setting of the connection of devices to a home gateway apparatus is simplified by providing the apparatus with a gateway function interconnecting a residential network and an external network; a database holding information setting the states of devices getting connected to the residential network and software for the setting, as settings information for each device; and a device setting processing part, setting, for a device newly requesting connection, the state of the device via the residential network by using the settings information, and, when getting accessed from the external network, making settings, with respect to the gateway function for making the firewall settings and the network address translation settings, on the basis of the network information further included in the settings information and the IP address granted to the device.
