Claim Text:
1. A handwriting verification method executed in a computer system, the method comprising: obtaining a handwriting test sample containing a plurality of available parameters, wherein the plurality of available parameters comprises geometric parameters and one or more non-geometric parameters; extracting the geometric parameters from the plurality of available parameters; based on the geometric parameters, deriving geometric features comprising an x-position value and a y-position value for each of a plurality of evenly distributed feature points in the handwriting test sample; performing feature mapping by finding mappings between one or more of the evenly distributed feature points in the test sample and one or more evenly distributed feature points in the reference sample, wherein the feature mapping includes: (i) selecting a feature point in the reference sample, and (ii) based on a pseudo-random value, determining whether to (a) remove a link from a selected point in the reference sample, or (b) define a new link between the selected feature point in the reference sample and a selected feature point in the test sample; and determining a handwriting verification result based at least in part on the mappings.
