PROBLEM TO BE SOLVED: To maintain high security even if a collation system of low precision is used or a fingerprint pattern is copied by considering the order of fingers to be inputted as a password, combining finger inputs for plural times and collating them. SOLUTION: A fingerprint input device 100 is constituted of a television camera, an A/D converter and a display device. The fingerprint feature quantity of a user and the input order of the fingers are previously registered in a fingerprint feature quantity file 110. The fingerprints inputted by a person who desires entering are collated with the fingerprints registered by a fingerprint collation device 120. A finger input order management device 130 judges whether a collation result is matched with the input order of the fingers, which is previously registered or not. Only when the prescribed number of input times (three times, for example) are terminated and the fingerprints are inputted in the finger input order of an input order registration table, a locking management device 140 opens the locking of a door. Thus, collation precision can be improved by the combination of the input order and biometrics information, which only a person himself knows. |
