The present invention provides an electronic wallet having a higher level of anonymity, security and convenience, which is capable of efficient electronizing of value information as well as which allows the user to efficiently manage the electronic value information. A presentation card indicating the fixed property of an electronic value is digitally signed by the service provider; a variable property is digitally signed with the private key of that electronic value. A service control, security information, representation control and representation resource are digitally signed by the service provider. These digital signature will be authenticated each time an electronic value object is generated.

A visual field calculation apparatus capable of accurately calculating a visual field range of a user without using a complex configuration is provided. The visual field calculation apparatus includes a saccade detector that detects a saccade on the basis of a first gaze direction detected at a first timing and a second gaze direction detected at a second timing, a saccade speed calculator that calculates speed of the saccade on the basis of a time difference between the first timing and the second timing, the first gaze direction, and the second gaze direction, and a visual field range calculator that calculates a displacement vector of a saccade whose speed exceeds a first threshold, and calculates an area including a final point of the displacement vector as the visual field range of the user.

Visual field calculation apparatus and method for calculating visual field

A display control apparatus includes: an input unit that receives state information indicating at least one of a state of a moving object, a state of inside of the moving object, and a state of outside of the moving object; and a controller that controls a displayer, which generates a predetermined image and outputs the predetermined image onto a display medium, based on the state information. The predetermined image shows a presentation image including text, when displayed on the display medium. The controller causes the displayer to generate a first predetermined image showing a first presentation image including first text corresponding to a predetermined event, determines whether the at least one state has made a predetermined change, based on the state information, and causes the displayer to generate a second predetermined image showing a second presentation image including second text corresponding to the predetermined event.

An electronic asset utilization system is constituted of a stationary terminal, such as a set-top box (STB), a mobile terminal, such as a portable cellular phone, and a server. The serverreceives an order for an electronic asset from the stationary terminalor the mobile terminal; downloads to the stationary terminalor the mobile terminalan electronic asset and an exchange or receipt certificate to be described later; retains the thus-issued electronic asset, exchange certificate, or receipt certificate; and settles a charge billed to the thus-ordered electronic asset. The stationary terminal, the mobile terminal, and the serverare connected to a communications network.

An electronic information backup system for safely back up electronic value information about electronic money and electronic ticket through communication in a server so as to exclude unauthorized actions when backup and restoring are performed and for restoring the electronic value information from the backup in case of emergency such as loss of key information. In this system, electronic value information is encrypted, the encrypted electronic value information is registered in an electronic safe server, and the user receives the registration, presents the registration to the server to receive the encrypted electronic value information, and decrypts the electronic value information with decrypting key data. The decrypting key can be kept in another server. The electronic value information and the decrypting key can be kept separately in different servers. It is possible to keep the sequence of number of the cryptogram to serve as the basic the decrypting key in the server, and to generate a decrypting key according to a decrypting key generation algorithm on the terminal side. In case of loss of the decrypting key, the possessor certificate information is verified and then the user can receive the decrypting key from the server.

Electronic information backup system

There is disclosed an apparatus for setting control information of a computer system comprising a control information request device for requesting the apparatus for setting control information of another computer system connected over a network to transmit the control information, when a storage device is judged not to store the information by the control information storage check device, a receive device for receiving the control information transmitted from the apparatus for setting control information of the other computer system and allowing the storage device to store it. There is also disclosed an apparatus for setting control information of a computer system comprising a receive device for receiving the request for transmitting the control information transmitted from the apparatus for setting control information of the other computer system, and a transmission device for transmitting the control information stored in a storage device to the apparatus for setting control information of the other computer system. There is further disclosed an apparatus for setting control information of a computer system comprising a control information registration request device for requesting the apparatus for setting control information of the other computer system connected over the network to register inputted control information. There is further disclosed an apparatus for setting control information of a computer system comprising a receive device for receiving the request to register the control information transmitted from the apparatus of the other computer system, and a storage device for storing the requested control information.
