摘要:
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.

To make an electronic value usable for both service on a network and service in the real world while ensuring security, convenience and economical efficiency, the electronic value issued for a user is controlled on an electronic wallet of a private electronic value bank, the electronic value controlled on the electronic wallet of a bank is cached in a mobile electronic wallet on a smart card of a user's portable terminal 5, and the electronic wallet is linked such that it is operated via the network when the mobile electronic wallet is operated. When the electronic value on the smart card is used for the service provided in a real environment such as a ticket gate of a train station, on-line transaction does not occur every time it is used, but the electronic wallet of the bank is updated when the portable terminal and the bank communicate later.

A terminal device sets a beneficial use time slot for regarding the electrical consumption in the beneficial use time slot as the beneficial, a waste use time slot for regarding the electrical consumption in the waste use time slot as the waste, and an efficiency improvement time slot for regarding the electrical consumption in the efficiency improvement time slot as the electrical consumption to be reduced. On the basis of the data of an amount of the electrical consumption of the device to be monitored, calculating an amount of the electrical consumption in each the time slot and displaying an amount of the electrical consumption in each time slot are preformed.

A data aggregation part 14 uses, as a data set, setting data for controlling an air-conditioning apparatus 31 and a refrigerating showcase 32, the amount of electricity consumed by the air-conditioning apparatus 31 and the refrigerating showcase 32 and operation data thereof, and environmental data containing outdoor temperatures, and classifies the data set for each outdoor temperature. An environmental condition-specific analyzer 15 obtains optimum setting data for accomplishing energy saving for each outdoor temperature, by using the data set for each outdoor temperature. The environmental condition-specific analyzer 15 also corrects the amount of electricity consumption of the data set on the basis of the number of people in a space counted by a people counter 35. A time zone-specific analyzer 16 obtains optimum setting data for accomplishing energy saving for each time zone by using the optimum setting data for each outdoor temperature.
摘要:
An information terminal that decrypts sealed data without returning program data after update to the state before update. The information terminal includes update certificate storage unit storing an update certificate for certifying update of the program data to be executed by CPU, and a selection unit which, when the CPU is to execute program data, judges whether or not digest of the post-update program data in the update certificate matches digest of the program data to be executed, and selects digest of the pre-update program data in the update certificate when it judges that they match. The CPU executes the post-update program data. The information terminal further includes a security device that stores an extend value of a program data digest when the pre-update program data is executed by the CPU according to a request from the selection unit.

An energy conservation diagnosis system manages electrical device K which consumes electricity to operate based on control schedule information, and comprises acquiring unit 14a, rule information generation unit 14b, operating determination unit 14c and display unit 12. Acquiring unit acquires operating information obtained by means of relating an operating condition of electrical device to a clock time. Rule information generation unit generates rule information by means of relating a rule on use of electrical device to a clock time, based on one or more predetermined time slots depending on a benefit of electricity consumed by electrical device. Operating determination unit acquires control schedule information of electrical device, and generates an image data by means of superimposing acquired control schedule information and rule information onto operating information so that each clock time is fitted to a clock time of operating information. Display unit displays the image data.
摘要:
A power control system controls electric devices so as to consume a power generated by a self-generated power facility using a natural energy, which is provided with a surplus power detection unit that detects the surplus portion of power generated by the self-generated power facility, and a device control unit that controls the operation of a plurality of electric devices. When the surplus power detection unit detects the surplus power, the device control unit controls one or more of a plurality of electric devices to perform predetermined operations so as to consume the surplus power.
