Fingerprint matching using sensor fabrication materials
Abstract
Elastic distortion of friction ridge skin is one of the major challenges in fingerprint matching. Since subsisting fingerprint matching systems cannot match solemnly distorted fingerprints, malefactors may intentionally distort their fingerprints to eschew identification. Subsisting distortion detection techniques require availability of specialized hardware or fingerprint video, constraining their utilization in authentic applications. In this paper we conduct a study on fingerprint distortion and develop an algorithm to detect fingerprint distortion from a single image which is captured utilizing traditional fingerprint sensing techniques. The detector is predicated on analyzing ridge period and orientation information. Promising results are obtained on a public domain fingerprint database containing distorted fingerprints.
