Abstract:
1. A method of fingerprint verification suitable for determining whether a claimant is one of a number of enrollees, the method comprising: identifying minutiae of an enrollee fingerprint, and minutiae of a claimant fingerprint; analyzing the geometrical correspondence between minutiae of the claimant fingerprint and minutiae of the enrollee fingerprint via affine transformation; determining whether the claimant fingerprint and the enrollee fingerprint match on the basis of the analysis and selecting identified subsets of the enrollee minutiae and identified subsets of the claimant minutiae. wherein minutiae are eliminated from and/or not selected for inclusion in said identified subsets if the minutiae is determined to be positioned on or near the boundary of the claimant or enrollee fingerprint; and wherein a minutiae is determined to be positioned on or near the boundary of a fingerprint if it is less than a predetermined geometrical separation from any one of the sides of a rectangle defined by the co-ordinates of the most outlying minutiae of the fingerprint.
