| Figure-Based Writer Verification by Matching between an Arbitrary Part of Registered Sequence and an Input Sequence Extracted from On-Line Handwritten Figures (2003) | |||||||||||||
Abstract | |||||||||||||
| This paper propose a method of writer verification based on on-line features extracted from a process of drawing a figure, and evaluate its performance on handdrawn figures by genuine writers and pretenders. In the proposed method, a person in registration writes only the reference figure, which is composed of as many parts as possible and the person can be verified with a arbitrary part of the reference figure. The verification is based on a spotting method called CDP (Continuous Dynamic Programming). From some requirements in authentication system, the proposed method is tested through some experiments using figures. The error rates in the experiment were different depending on conditions such as kind of on-line features, minimum number of strokes comprised in acceptable test sequence as input, figure for determination of threshold and the genuine writer. The result of the experiment shows that the proposed method is effective. | |||||||||||||
