  • Patent number: 8165601
    Abstract: In an indoor positioning system, for establishment of a cost sharing system, the positioning information transmission device does not directly transmit positional information but performs concealment and variablization on the device ID and transmits the concealed and variablized device ID. The positioning information management server stores and manages correspondence between the device IDs and positional information, and performs conversion from the device ID to the positional information in accordance with the correspondence. Further, the problem of conflict between concealed IDs upon concealment of positioning identification information by the positioning information transmission devices, which occurs when all the positioning information transmission devices use the same secret key, can be prevented. The system can be operated even when the bit length of the device ID is short.

  • Publication number: 20110053614
    Abstract: A positioning information transmitter transmits a positioning identifier instead of directly transmitting position information. A positioning information management server stores and manages the positioning identifier and the position information while correlating them with each other. In response to a position information request with a positioning identifier, the positioning information management server converts the positioning identifier into position information according to the aforementioned correlation. Furthermore, the positioning information management server updates the positioning identifier to be transmitted from the positioning information transmitter in a certain time by using predetermined means.

  • Patent number: 7587221
    Abstract: An attribute value of a matter accompanied by a sensor is transmissibly accessible in a sensor node system constituted by wireless terminal computers having the sensor, the wireless communication base stations and server computers. The wireless terminal computer reports at the time of wireless communication an identification number of a wireless communication base station with which it communicates previously. A relay processing service is dynamically constituted so that when a wireless communication base station different from itself is reported, the wireless base station as the communication counter-part can transmissbly look up the wireless terminal computer from a host computer.

  • Patent number: 7587200
    Abstract: A computer system including wireless terminals which transmit information, a business application server which performs a predetermined operation based on information received from the wireless terminals, and a base transceiver station which relays communications between the wireless terminals and the business application server, are provided. The base transceiver station, to manage said plural wireless terminals in groups, stores a group definition table showing a correspondence between the wireless terminals and the groups, stores the information received from the terminals in a state history table which manages the state history of the wireless terminals, extracts difference information between the information received from the wireless terminals and the information stored in the state history table, summarizes the extracted difference information for each group, and transmits it to the business application server. The data amount received by a business application server is thus reduced.

  • Patent number: 7487920
    Abstract: An integrated circuit card operation management system and method are provided. In one example of the system, a collator system is provided for receiving a user request to determine whether the application program can be loaded, for acquiring a card policy from a card issue management system, and for acquiring an application program policy from a service provider management system. The collator system requests card related information of the card issue management system and requests application program related information of the service provider management system. The collator system specifies a definition format. The card issue management system and the service provider management system extract requested information from existent information, convert the requested information according to the specified definition format, and transmit the converted information to the collator system.

  • Patent number: 7360088
    Abstract: A system is provided which compensates a low operational performance of a conventional integrated circuit (IC) card by setting a substitute server computer between the IC card and a business server computer in a system using the IC card. Substitute processing using an authentication result is realized by setting an IC card authentication server computer in addition to the business server computer and sending an authentication result of the authentication server computer to the IC card, substitute server computer, and business server computer. Thus, because the substitute server computer does not directly authenticate the IC card, the quantity of authentication information in the substitute server computer is substantially reduced and authentication processing becomes efficient.

  • Publication number: 20080045218
    Abstract: In the prior art, the initialization process for communication between a wireless communication terminal and a base station is executed by activating the wireless communication terminal with a built-in battery. As a result, the problem is posed that a great amount of power is consumed during the initialization process and the battery of the wireless communication terminal is consumed early. Especially, in the case where the network configuration is required to be changed frequently, the life of the battery of the wireless communication terminal is extremely shortened resulting in a low practical value. In view of this, a passive RFID is mounted on the wireless communication terminal, and the initialization process is executed by the power supplied from the base station using the RFID interface. As a result, the battery consumption of the wireless communication terminal can be prevented in the initialization process.

  • Patent number: 6931379
    Abstract: An IC card that allows a service provider doing a business of loading an application into the IC card to dynamically load the application into the IC card safely after the issuance of the IC card without making a contract directly with a card issuer issuing the IC card and without establishing a communication with the card issuer. The card issuer issuing the IC card hands over an encryption key in advance to a third party other than the card issuer in order to entrust the third party with work to authenticate an application to be loaded or to allow the third party to function as an agent on behalf of the card issuer. The card issuer issues an agent certification to the third party to be used as evidence showing that the third party is an agent representing the card issuer.
