Abstract
Secure detection of a finger in contact with a sensor. A fingerprint collation program is proposed, in which data outputted from a fingerprint reading sensor is classified into predetermined patterns according to data of a maximum threshold value or more, data of a minimum threshold value or less and an amplitude constituted by a difference obtained based on the maximum and the minimum values of the outputted data. Such fingerprint collation program determines the object that is in contact with the sensor based on the classified patterns. For example, determines whether the object is a finger or not. The present invention may be applied to a fingerprint collation apparatus.
