On-line signature verification for e-finance and e-commerce security system

Online signature verification is a new and active topic in the research and application fields of biometrics. This paper proposes a low cost online signature verification method based on the matching of curves about x- and y-axis attaching some dynamic features. Just as human being's behavior, different local weight and unfixed threshold are introduced to improve the performance of signature verification system. Finally, this paper presents some applications of online signature verification on ATM, onsite credit card verification and Internet e-commerce.
