摘要
Techniques for generating a distorted fingerprint representation for a given fingerprint image are provided. First, at least one fingerprint feature point from a given fingerprint image is selected. At least one representation of a region proximate to the selected fingerprint feature point is then generated. Next, the representation of the region proximate to the selected fingerprint feature point is distorted. The distortion comprises applying a random projection to the representation to generate a randomly projected representation of the region proximate to the selected fingerprint feature point. A distorted template is then formed, wherein the distorted template comprises the randomly projected representation of the region proximate to the selected fingerprint feature point.
