Finger print collating system

Abstract

Abstract PURPOSE:To improve collation accuracy by reflecting the difference of a reading condition and an individual difference by registering one of read data of plural number of times as a fundamental finger print data, and at the same time, registering the factor of a coincidence between other data and the fundamental finger print data. CONSTITUTION:At the time of registering, the pattern of the finger print is read three times on a finger print reading part 13, and a fundamental coincidence factor P is obtained from the coincidence factor A of the finger print data between a first time and a second time, and from the coincidence factor B between the first time and a third time, and is registered and stored in a memory device 16, and besides, the finger print data of the first time is stored in the memory device 16 as a registered fundamental finger print data. At the time of collating, the collation between the read-out registered finger print data and the read-in input finger print pattern is performed, and its coincidence factor Q is calculated, and if the coincidence factor Q exceeds the fundamental coincidence factor P, a display to mean that the confirmation of the person in question is permitted is displayed on a display device 12.
