On-Line Signature Handwritten Verification Algorithm Based on Stroke Matching
Fangjun Luan, Shi-liang · 2005
On-line signature handwritten verification is a topic in the field of biometric authentication now.By comparing the picture,stroke,speed and pressure of input signaturs with genuine signatures in database,the computer can distinguish the true or false of a handwritten signature real-timely.Stroke-matching and result judgment are the keys to this problem.This paper presents a stroke-matching algorithm of handwritten signature verification.The algorithm is effectual to be examined by signature data from SVC 2004(First International Signature Verification Competition).The FRR(False Reject Ratio) is 2.0% and all forgeries are rejected.The paper also introduces distance calculation formula based on weighting H′ module to calculate the difference between input signatures and true signatures.On-line signature handwritten verification is very convenient,quick-made,suitable to verification and its effectiveness has been illustrated by practical examples.
