A minutiae-based method to store and compare fingerprints

Biometrics refers to certain physical or behavioural characteristics that are unique to every person. Biometrics, including fingerprints, are used for the measurement and analysis of biological data for identification purposes. This paper presents a new method to extract and compare fingerprint biometrics based on minutiae features. Only two reference minutiae are used to enhance the efficiency of the verification process with no need to match all the combinations of the extracted minutiae from the intellectual reader with the reference minutiae in the alignment algorithm. The method is implemented and tested with an average decrease of 80% in the number of combinations required to be matched with the reference minutiae when two reference minutiae points are used instead of one to align and match fingerprints.
