1. A method for transforming a multi-dimensional biometric feature point set, the method comprising: converting the multi-dimensional biometric feature point set to a canonical position and orientation; applying a non-invertible transform function to individual points of a plurality of points of the biometric feature point set using a computing device, the non-invertible transform function including a point offset direction as a first transform and a point offset amount as a second transform; and providing a transformed biometric feature point set comprising a plurality of transformed points, wherein the point offset direction and the point offset amount are separately applied to the individual points.
