摘要:
An electronic information format includes a header module and a history module in addition to source electronic information. A control program is incorporated in the header module, and the control program is expanded on a reception side. An operation on the electronic information on the reception side is recorded by the control program, and is written in the history module when the electronic information is closed. On a providing side, there are provided a program for creating electronic information of the present format, and a program for reading the history data from the electronic information. By this system, when the electronic information is provided, an operation, which is executed on the electronic information on the reception side, is recorded, and the record can be confirmed on the providing side.

This invention provides an information search system including a management table which stores a name of a memory area and memory area information indicating the memory area in association with each other. When received source information search destination information indicates that source information to be searched is stored in a memory, the information search system searches the management table for a name of a memory area which matches a received source information name of the source information to be searched. When the name of the memory area which matches the received source information name of the source information to be searched is retrieved, the system acquires information which matches the received search target condition information from memory area information associated with the retrieved name of the memory area.

A processing machine processes a work and repeats processes on the work, thereby consuming energy. Within the consumed energy, room for improvement is computed by an energy monitoring device and is referred to as an amount of energy that can be improved. An energy monitoring device includes a power data acquirer that acquires a time-series power data measured by a power meter, a cycle detector that detects a single-cycle power data from the power data acquired by the acquirer, a divider that divides the single-cycle power data detected by the detector into an added-value creating portion and an unproductive portion, and a computing unit that computes an amount of energy consumed in the unproductive portion divided by the divider and defines it as the amount of energy to be improved.

A terminal identification method is provided which enables two-way communications between terminals and a network while identifying terminal IDs and protecting privacy. Also, authentication method and system are provided which require no complicated calculating process, less steps and smaller amount for wireless communications, and less power consumption. A server and terminal share a hash function and an initial value determined for each terminal, calculate the same temporary ID by hashing the initial value the same number of times with the hash function, and identify the terminal using the calculated temporary ID. The server and the terminal also hold a common hash function and authentication information, acquire an authenticating communication parameter from communication parameters temporarily common during communication, and generate an authentication key using the authentication information, the authenticating communication parameter, and the hash function. Then at least one of the server and terminal performs authentication using the generated authentication key.
