User identification through sequential input of fingerprints

摘要

An identification system using biometric information of human body parts and a secret sequence code. In particular, biometric information of human body parts is used to form the secret sequence code. Specifically, a combination entry device recognizes user's fingerprints which are entered as a sequence. The fingerprints must be entered in the proper sequence in order to be recognized by the system. The fingerprints are preferably recognized using a fast technique with a low-probability level of rejection. While the sensor can be fooled for any one fingerprint. The use of a plurality of different fingerprints improves the identification capability. In particular, the combination of fingerprints in the proper order is necessary to undo the lock.
