Abstract

Authentication of individuals is rapidly becoming animportant issue. On-line signature verification is one of themethods that use biometric features. This paper proposes anew HMM algorithm is for on-line signature verification.After preprocessing, input signature is discretized in apolar coordinate system. This particular discretizationleads to a simple procedure for assigning initial state andstate transition probabilities.This paper utilizes only pen position trajectories, noother information is used which makes the algorithmsimple and fast. A preliminary experiment shows that theproposed algorithm appears to be promising.
