9. A handwriting verification method executed in a computer system, the method comprising: performing feature matching between geometric features of a handwriting test sample and geometric features of a reference sample, wherein the feature matching comprises defining one or more links between one or more feature points in the test sample and one or more feature points in the reference sample; obtaining a count of consecutive unlinked feature points in the test sample; and outputting a handwriting verification result based at least in part on the feature matching and the count of consecutive unlinked feature points in the test sample.

The method of claim 9 , wherein the feature matching includes: initializing a pseudo-random value generator to generate a sequence of pseudo-random values, wherein the feature matching is based on a pseudo random value generated by the pseudo random value generator; and if matching is not sufficient, performing another feature matching by the using another pseudo random value generated by the same uniform random value generator.
