Abstract: A method and an apparatus for matching a fingerprint by using minutiae and binary image of the fingerprint are provided to reduce false acceptance rate by executing the fingerprint matching. An apparatus for matching a fingerprint includes an extracting unit(210), a comparing unit(220), a compensating unit(230) and an authenticating unit(240). The extracting unit receives the first fingerprint image and the second fingerprint image, extracts minutiae and binary image from them, and outputs the minutiae and the binary image. The comparing unit acquires position and orientation difference between two minutiae on the basis of the minutiae information of the first fingerprint image and the second fingerprint image, and outputs the position and orientation difference. The compensating unit compensates the minutiae and the binary image of the comparing fingerprint and the registered fingerprint on the basis of compensating parameters obtained from the minutiae and the binary image outputted by the comparing unit. The authenticating unit performs an authentication procedure via similarity by comparing the compensated minutiae and binary image of the comparing fingerprint with those of the registered fingerprint.

Abstract: In an apparatus for authenticating a user by employing feature points of a fingerprint image of the user, a fingerprint image input circuit scans a fingerprint of a user to be registered to provide a first fingerprint image and a fingerprint of a user to be authenticated to provide a second fingerprint image. A host provides registered feature points data corresponding to the first fingerprint image and target feature points data corresponding to the second fingerprint image. A security token circuit estimates a position difference and a direction difference between pairs of a registered feature point and a target feature point and corrects the two feature points based on the position difference and the direction difference to provide authentication result data.
