PURPOSE: To perform a processing for deciding whether or not a user has access right speedily at a user's access request by using physical body feature data and to securely maintain secrecy protection. CONSTITUTION: At the access request, the physical body features of the user are measured by feature measurement units 14-1, 14-2, and 14-3, and further processed by data degeneration units 13-1, 13-2, and 13-3 as feature data having linear projection, etc., degenerated. Computer systems 11-1 and 11-2 send the feature data to a collation server 15 through a communication network 12. The collation server 15 performs a collation process according to feature data previously stored in a file system 16. It is judged from the collation result whether or not the user has the access right, and the access allowed/disallowed state is sent to computer systems 11-1 and 11-2. |
