METHOD AND APPARATUS FOR VERIFYING STATIC SIGNATURES USING DYNAMIC INFORMATION

摘要

In a process of signature verification, an off-line test signature is compared to one or more on-line reference signatures. Dynamic data obtained fromthe 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 include s evaluating a dynamic error, based at least in part on such sequencing of the test signature. In some further embodiments, the invention includes producing a rendering of at least one on-line reference signature as a two-dimensional i mage, and evaluating a static error based, at least in part, on shape-matching between therendered image and the test signature.
