Symbolic Representation of On-line Signatures

In this paper, we present a method of representing on-line signatures by interval valued symbolic features. Global features of on-line signatures are used to form an interval valued feature vector for representing signatures. A method of signature verification based on symbolic representation is proposed. We investigate the feasibility of the proposed representation scheme for signature verification on a large MCYT signature database. Unlike other signature verification methods, the proposed method is simple and efficient. Several experiments are conducted to demonstrate the ability of the proposed scheme in discriminating the genuine signatures from the forgeries.
