Abstract: A biometrics template matching method includes the steps of: providing a reference biometric template and a candidate biometric template, each including position data and orientation data of a respective plurality of minutiae; comparing the orientation data of each minutia from the candidate template with the orientation data of each minutia from the reference template; when the orientation data of a selected pair differ by no more than a first threshold, determining a displacement vector representative of the difference in position data of the selected pair of minutiae; determining the maximum number of displacement vectors that differ from each other by less than a second threshold; if the maximum number of displacement vectors is less than a third threshold, returning a mismatch, otherwise returning a match.
