A real-world online signature verification system based on correlation algorithm

Abstract

Handwriting signature is one of features of the biometric identification and authentication, which is used to verify or authenticate a 'signer' and the document signed. US law (the electronic signatures (E-Sign) in Global and National Commerce Act) and the United Nations Commission on International Trade Law Model Law on Electronic Commerce already grant electronic signatures legal validity equivalent to traditional hand-written counterparts. The intention of those laws is to cut costs while providing more stringent security, especially in the emerging e-commerce arena. In this paper, we (a) describe fundamentals and the current status of electronic signatures in detail. (b) Propose an online handwriting signature verification algorithm by using four online elements as the verification features (they are X axle, Y axle, pressure and velocity (time). Correlation algorithm is used to test and verify signatures. (c) Develop a real world application system with the online electronic signature.
