Abstract: In a data conversion auxiliary module which is at a higher level than a file system in a disk management hierarchy, data stored in a storage medium, which becomes an object, is successively accessed. Then, a data conversion module captures a sector-unit access request to a device driver from the file system, converts data of a sector which is returned from the device driver, and writes the conversion data in the sector. Thereby, data conversion can be executed on a specific region of the storage medium, which is associated with the data in the storage medium.

Abstract: 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.

Abstract: An operation request from a process or OS for computer resource(s) managed by the OS, such as a file, network, storage device, display screen, or external device, is trapped before access to the computer resource. It is determined whether an access right for the computer resource designated by the trapped operation request is present. If the access right is present, the operation request is transferred to the operating system, and a result from the OS is returned to the request source process. If no access right is present, the operation request is denied, or the request is granted by charging in accordance with the contents of the computer resource.

Abstract: 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.
