Paper Abstract

In this paper, a direction sequence string matching based on-line signature verification system is proposed. A signature is coded as a direction sequence string. The modified edit distance is used for string matching. The test signature is compared with 5 reference signatures and distance is given by averaging the 5 distances. A verification result is given by comparing the distance measure with a pre-calculated threshold. The experiment shows a result of 4.7% equal error rate (EER).
