Abstract: In this paper, an on-line signature verification scheme based on split-and-merge matching mechanism is proposed. Each word in the signature is specified with static and dynamic features: a sequence of (x, y) coordinates and a sequence of (x, y) velocities. We employ the split-and-merge matching mechanism for each input sequence of coordinates or velocities with the corresponding sequence of the reference template. Alignment and refinement are exploited in the matching to justify the data skew problem. The accumulated coordinate and velocity distances are compared with corresponding verification thresholds to determine the genuineness of the input signature, Algorithms to compute reference templates and verification thresholds are also proposed. The performed simulation results support the effectiveness of this signature verification scheme.
