Implementation and analysis of a handwritten signature verification technique

Abstract

There is considerable interest in authentication based on handwritten signature verification because it is superior to many other biometric authentication techniques such as finger prints or retinal patterns, which are reliable but much more intrusive. The paper details a number of experiments using a signature verification technique which is unlike any other reported in literature. Specifically, characters are used to represent various features of a signature image allowing the use of existing and proven string distance metrics to determine distances between signatures. Extensive testing shows that our proposed system is comparable with, and in many aspects better than the highest quality signature verification techniques presented in literature.
