Abstract
Various verification methods for on-line handwritten signatures have been proposed; however, reflecting inter-stroke information in the verification has not been considered. Hence, this paper suggests a verification method that uses Shape Context. In this paper, the verification method is divided into two methods. One is the basic method and the other is the Shape Context method. The basic method treats x-y coordinates, pen-pressure, pen-inclination, altitude and writing time and the Shape Context method treats inter-stroke information as point distribution. Also, the Shape Context method does the verification by incorporating a weighted evaluation of the average pressure value at each stroke. In the comparison experiment, FRR decreases from 4.14% to 1.54%, and FAR decreases from 4.06% to 2.01%. The experimental results show the effectiveness of the inter-stroke information method.
