MA Si-liang · Journal of Chinese Computer Systems · 2009
With the development of computer network and biometric identification technology,identity verification with biologic characteristic feeds the need of the information age.Hand-written signature verification becomes a kind of the most acceptable way of identity verification because of it as the sign of authorization for a long time.In this paper,the distances measure of DTW is improved.Based on the characteristics of the shape of the time series itself,the problem that nonlinear warping of time series of on-line signature is solved.The experiment result is the ERR 3.0% when skilled forgeries are used.It is suitable to use On-line hand-written Signature as a mothod of identity verification.
