摘要:
A context information collection and distribution system registers read identification information in a computer device that manages and controls an RFID tag reading device and is located in a lowest hierarchy in wide area network topology. The computer device located in the lowest hierarchy in the wide area network topology notifies a computer device located in a higher management domain hierarchy that the computer device located in the lowest hierarchy manages read identification information of a target. Further, the computer device located in the management domain hierarchy notifies a computer device located in much higher ID system hierarchy that the computer device located in the hierarchy just under the management domain hierarchy manages the read identification information of the target.

An object detection method is executed by an object detection system for detecting data corresponding to a specific object in data received from sensors. The system includes a plurality of monitors, an application device, and a data accumulator. The method includes the followings. The application device specifies reference data corresponding to the specific object. Each of the plurality of monitors samples data received from a sensor to generate and transmit sampled data. The data accumulator analyzes sampled data received from each of the plurality of monitors in accordance with an analysis logic to generate first analyzed data. The data accumulator determines whether the first analyzed data matches the reference data specified by the application device. The data accumulator transmits a detection notification to the application device when analyzed data generated from sampled data received from a monitor out of the plurality of monitors has matched the reference data.

The present invention is an authentication method for disclosing identification data of an object and authenticating when referring to data of the object corresponding to the identification data based on the identification data and can associate a tag device and data of a referring entity and authenticate that data of the tag device is referred by a proper referring entity by generating a third value by conducting a predetermined calculation with a temporary first value indicating a most recent referral to the identification data of the object and a temporary reference second value issued to a referring entity of the identification data for each referral, and authenticating a relationship between the object and the referring entity by verifying the third value.

Group information is assigned for each communication object and communication data is transmitted by adding the group identifier, thereby realizing a communication control in accordance with the communication object. That is. when a communication device performing radio communication by constituting an ad-hoc network with a plurality of devices communicates with a destination device via at least one of the devices constituting the ad-hoc network, the communication device acquires group information assigned to the communication group having the common object with this communication, references a communication control data table containing communication control information for each of the group information so as to acquire the communication control information corresponding to the group information, adds the group information to the communication information to be transmitted to the destination device so as to generate communication data, identifies a device which relays the communication according to the communication control information, and transmits the communication data to this relay device.
摘要:
A group management server receives, from a device joining an ad hoc group related to the provision of a service as a member thereof, a member registration request including communication information inclusive of a method for communication with the device becoming the member and registers the device in the ad hoc group. The group management server provides the communication information to a provider of the service in response to a request from the service provider. The service provider performs communication related to the provision of the service with each of members by using the communication information.
摘要:
A connection for transmitting an ATM cell having a specified identifier through a predetermined interface is set in an ATM switch unit. A protocol control unit receives a call control signaling message from a user via the ATM switch unit. Connection cache data retains connection information which specifies the connection set within the ATM switch unit and indicates whether the connection is in an activate or halt state. A connection cache unit, when the call control signaling message received by the protocol control unit indicates a request to release any one of connections, sets the connection information specifying the connection so as to indicate the halt state. The connection cache unit, when the call control signaling message received by the protocol control unit indicates a request to set the connection for a certain call, allocates the connection indicated by the connection information showing the halt state to the call.
摘要:
A network access control method for a network system comprising network apparatuses having a packet filtering function, a service server connected with an IP network via the network apparatus, providing a service to a user, a user terminal connected with the IP network via the network apparatus, for the user to utilize the service provided by the service server, a reception server connected with the IP network via the network apparatus, receiving an access from the user for the service server, and an access control server controlling the network apparatuses. The method comprising the steps of a) the reception server receiving access request information from the user terminal, and holding it, and b) the access controlling server performing traffic control such as to extract, based on processing capability of the service server and a traffic amount for the service server, such an amount of the access request information as that the service server can optimally deal with, so as to allow the access for the service server.
摘要:
An authentication method is disclosed that makes the identification information of an object public and performs authentication in referring, from the identification information, to the information of the object corresponding to the identification information. The method includes generating a third value through a predetermined operation of a temporary first value generated every time the identification information is referred to and a temporary second value generated for a referrer to the identification information; encrypting the third value by first and second different encryption methods; decrypting the third value encrypted by the first encryption method in a tag device attached to the object; and decrypting the third value encrypted by the second encryption method in an apparatus managing the information of the object, and comparing the third value decrypted in the apparatus with the third value decrypted in the tag device, thereby verifying the relationship between the object and the referrer thereto.
摘要:
An application server receives presence information with anonymous identification information of a presentity client. The application server transmits a message to an information distribution proxy. The message is addressed not to the identification information of the presentity client, but to the anonymous identification information of the presentity client. The information distribution proxy converts the anonymous identification information into real identification information, and forwards the message to the presentity client. Therefore, the application server does not know the real identification information of the presentity client. That is, there is no need for the application server to directly treat personal information, thereby producing the effect of eliminating the need for strict management of presence information.
