Abstract: An information processing device includes a first unit which predicts use data used in the future on the basis of action plan information resulting from prediction of an action of a user, and outputs use data identification information; a second unit which predicts a communication state in a situation indicated by the action plan information on the basis of the action plan information and communication environment information regarding a communication environment of the terminal, and outputs information regarding the predicted communication state; and a third unit which calculates a prefetch necessary degree regarding each of the use data on the basis of the use data identification information and the information regarding the predicted communication state.

Abstract: It is possible to transfer a plurality of independent services used on a certain terminal to other terminal and use them with ease.

Abstract: An electronic value exchange system which includes first and second terminals (1d), (1e) which at least execute electronic value exchange with each other, and an authentication device (110), each of the first and second terminals has a value storage unit (13) which stores the electronic value; an exchange contract data storage unit (17) which stores exchange contract data representing contents of the electronic value exchange; an exchange state storage unit (16) which represents a state of the electronic value exchange; a commit order storage unit (14) which stores a commit order which indicates that which of the first terminal and the second terminal is the first to execute; an identification information storage unit (15) which stores identification information assigned to every process of transmission/reception of the exchange contract data; and a first exchange execution unit (12) which executes transmission/reception of the exchange contract data with respect to each of the first and second terminals and

Abstract: A method makes possible the transfer independent services used on a certain terminal to another terminal and easy use of them. A service transferring method of transferring service being used at a transferring source terminal (TST) to a transferring destination terminal (TDT), in which information about correlation between a session ID which identifies a session between a service server which provides the service and the TST using the service and a terminal ID of the TST is stored in at least either one of the service server and a transfer management server (TMS), and either one of the TST and TDT transmits terminal IDs of the one terminal and the other terminal to the TMS to notify service transfer and upon receiving the notification of the service transfer, the information about correlation between the session ID and the terminal ID recorded in either the service server or the TMS updates.

Abstract: Only a limited number of service servers have been provided with the function of feeding back profits obtained through cooperation of multiple service servers to developers of cooperation modules and business entities running the service servers as incentives. In the present invention, a cooperation server for achieving cooperation between the service servers includes: a business entity data storage means for storing business entity data of the respective service servers; a cooperation module storage means for storing cooperation modules used for achieving cooperation between the service servers; a developer data storage means for storing developer data related to developers of the cooperation modules; a cooperation history storage means for storing cooperation history data of the cooperation modules; and an incentive settlement means for performing calculation of amounts of incentives and payment of the incentives.

Abstract: A data processing device includes means (103) for receiving a signal of an object identifier uniquely assigned to an object, and means (104) for executing a plurality of application programs corresponding to the received object identifier. A plurality of applications can be processed on the basis of an object identifier so that the operation can be simplified. When the device include a client terminal (105) and an application server (108), data processing is possible even when they are located in remote sites.
