On-line signature verification using point pattern matching algorithm

Authentication of persons has been known as a paramount part in society. Security requirements have given biometrics much attention. Verification of the signature is one of the biometric methods used in recognition systems. This paper presents a new method to verify an online signature of a person. In features extraction step, local parameters are extracted as time functions of different dynamic properties. In recognition phase the Discrete to Continuous Algorithm is applied on features to verify the signature claimed by a person. The results obtained by the proposed algorithm show a good accuracy rate.
