Abstract

The invention discloses a computer-system-based handwritten signature stability evaluation method. The method comprises the following steps of: acquiring a signature to be tested and a signature sample set of the same writer by using handwriting input equipment or extracting the signature to be tested and the signature sample set of the same writer from the conventional signature database, wherein the signature to be tested is a handwritten signature requiring stability analysis, and the signature sample set is a handwritten signature set for the stability calculation of the signature to be tested; performing signature similarity evaluation on each signature sample in the signature sample set and the signature to be tested by adopting signature segmentation matching calculation and locally-matched segment difference calculation, obtaining the number of signature samples similar to the signature to be tested in the signature sample set according to signature similarity evaluation, and comparing the number with a preset threshold value to judge whether the signature to be tested is stable or not to finally finish the stability evaluation of the signature to be tested. The handwritten signature stability evaluation method is careful and comprehensive, and signature detail information extraction problems which are neglected by the conventional handwritten signature stability evaluation method are effectively solved.

Description

technical field [0001] The invention relates to the technical field of online handwritten signature authentication, in particular to a method for evaluating the stability of handwritten signatures based on a computer system. Background technique [0002] As one of the important contents of biometric identification technology, handwritten signature authentication utilizes personalized writing features to realize identity identification. According to different data acquisition methods, signature authentication can be divided into offline signature authentication and online signature authentication. Compared with offline signature verification using static images, online signature verification uses handwriting pads and other devices to collect handwriting information generated during the writing process, which can obtain richer information and has higher accuracy. Therefore, it has broad application prospects. [0003] The precondition for using biometrics as the basis for ide...
