ABSTRACT— Automatic fingerprint identification system includes person identification process based on fingerprint which is in digital form. Fingerprint identification system consists of acquiring fingerprint module, classification module, and the matching module, which it performs a comparison between the unknown input fingerprint and the others stored in the fingerprint database and related to the class labeled by the classification module. In this paper, extended are used in fingerprint analyzing process for extracting local features. In extraction local features, extended moments gave best results than when using centralized invariant moments with order 3. for decision making in identification, K_NN classifier used in this work.
Keywords— Biometrics, Pattern Recognition, invariant moments, Fingerprint, Authentication, Identification, K_NN.
