On-Line Signature Handwritten Verification Algorithm Based on Stroke Matching

TLDR: This paper presents a stroke-matching algorithm of handwritten signature verification that is effectual to be examined by signature data from SVC 2004, and introduces distance calculation formula based on weighting H′ module to calculate the difference between input signatures and true signatures.

Abstract: On-line signature handwritten verification is a topic in the field of biometric authentication nowBy 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-timelyStroke-matching and result judgment are the keys to this problemThis paper presents a stroke-matching algorithm of handwritten signature verificationThe algorithm is effectual to be examined by signature data from SVC 2004(First International Signature Verification Competition)The FRR(False Reject Ratio) is 20% and all forgeries are rejectedThe paper also introduces distance calculation formula based on weighting H′ module to calculate the difference between input signatures and true signaturesOn-line signature handwritten verification is very convenient,quick-made,suitable to verification and its effectiveness has been illustrated by practical examples
