Combination of Fingerprints to Secure Privacy

A. N. Dalvi, D. G. Chougule

Abstract: In this paper the fingerprint protection security by combining two different fingerprints into another identity is discussed. Here combined template is used to strengthen the security by extracting minutiae positions and reference points from one fingerprint and orientation and reference points from other fingerprint, we generate mixed minutiae template in enrollment phase. In authentication two stage matching process is used for matching mixed template with two query fingerprints. Using existing fingerprint reconstruction technique we can convert mixed template into real combined fingerprint.
