Minutiae based fingerprint matching techniques

Fingerprints are unique, permanent and universal. The minutiae of fingerprints of a human have sufficient details. We can use these non-trivial details as identification marks to verify the fingerprints. The purpose of this paper is to investigate and implement the working of minutiae based fingerprint matching system. Minutiae based fingerprint matching is widely used for fingerprint verification. In this method first, Fingerprint image is enhanced using Fast Fourier Transform and converted to binary image for further processing. In second step, image is thinned and minutiae are extracted. Finally, minutiae pairs of two fingerprints are matched to get matching score. This method has the ability to find the similarity between input minutiae sample and the stored minutiae sample without using the tiring investigation. By using the database fingerprints of different people, the performance of the system has been computed.
