In a process of signature verification, an off-line test signature is compared to one or more on-line reference signatures. Dynamic data obtained from the reference signature or signatures may be used to improve the thinning of the test signature. Such data may also be used for segmenting the test signature and sequencing the resulting strokes. In some embodiments, the invention includes evaluating a dynamic error, based at least in part on such sequencing of the tes t signature. In some further embodiments, the invention includes producing a rendering of at least one on-line reference signature as a two-dimensional image , and evaluating a static error based, at least in part, on shape-matching between the rendered image and the test signature.
