  • Patent number: 7660992
    Abstract: An electronic data storage system stores electronic data with attaching an electronic signature, and output the electronic data along with the attached electronic signature, which decreases the operation costs with a simple operation. By using a public key-based signature, a third party can verify the data, and by using a secret check code, the electronic signature at registration is always valid without risk of falsification. Also by attaching an electronic signature at access, the validity of the stored data is assured, and a third party can verify the data. By using all of these features, the verification by a third party becomes possible over the long term. In this way the long term storage of electronic data is implemented.

  • Patent number: 6795834
    Abstract: When a sweeping process and a backup process are performed on an electronic library file in an electronic library, a file storing a history of the sweeping process or a history of a backup process is generated, and the sweeping and the backup processes are managed. Thus, a user can easily manage as to which medium an original document has been swept to or where a backup copy of the original document is. If the uniqueness of the original document shown in a sweep history and a backup history can be secured, the problem that there can be a plurality of original documents on the storage media of a plurality of electronic libraries can be avoided.

  • Publication number: 20030206193
    Abstract: The present invention provides a communication control system that includes a control terminal having a display unit for displaying an image and a controlled computer, and transmits image information stored in the computer to the terminal. The terminal transmits image display capability information of the terminal, and the computer then receives it. The computer processes the image information of the computer based on the image display capability information of the terminal, and transmits it to the terminal. The terminal receives the changed image information and displays it on the display unit. This process allows efficient communication. When such control is stored as a program in a storage medium, a general computer can be controlled.
