APPARATUS AND METHOD FOR THE IDENTIFICATION OF FAKE FINGERPRINTS

摘要

An apparatus for identifying fake fingerprints has electrodes disposed upon or along a platen of a fingerprint scanner and if finger skin presented to the platen are real and alive is determined in accordance with analysis of electrical signals received from the electrodes Electronics of the apparatus and/or computer system determines one or more liveness parameter in accordance with signals received from electrodes Information from an image of the fingerprint may be used to select which electrode signals to use for liveness detection To further confirm the presence of a live finger, additional liveness parameters like pulse or temperature may also be sensed The skin may be one of in contact with the platen of the fingerprint scanner, separated from direct contact with the platen's electrodes by an insulating layer or a pad, or not in physical contact with the platen or a pad thereupon.
