Computer network system and personal identification system adapted for use in the same

Abstract

When a request to access a file or the like is made, a characteristic measuring unit measures the physical characteristic of a user of a computer system. A data degenerating unit processes the measured physical characteristic as degenerated characteristic data like a one-dimensional projection and outputs the degenerated characteristic data to the computer system. The computer system sends this characteristic data to an identification server via a communication network. The identification server performs an identification process in accordance with characteristic data preregistered in a file system. In accordance with the identification result, it is determined whether or not to approve the access authorization by the user and the permission or rejection of the access is sent back to the computer system via the communication network.
