Abstract
An apparatus for distinguishing living body fingerprint from artificial fingerprint and a method thereof are provided. A living body recognition unit determines whether fingerprint in question is living body fingerprint or not, based on the unique color of the living body fingerprint and a change of the fingerprint color which is caused due to a change of contact pressure when the living body fingerprint is contacted with the fingerprint input window. A fingerprint recognition apparatus computes color information from the fingerprint image acquired by the color image sensor, and color change information based on the change of contact pressure, and determines whether the fingerprint in question is the living body fingerprint by determining whether or not the computed color information meets a reference color range and/or if the color change information meets a reference condition.
