Abstract: In order to shorten the time for offline handwritten signature recognition and reduce the probability of false positives, an offline handwritten signature recognition method based on generative adversarial networks is proposed. Firstly, select pen pressure, pen tilt angle, pen azimuth angle, and multi-level velocity moment as the main dynamic features of offline handwritten signatures, and calculate the Pearson correlation coefficients of these dynamic features. Secondly, calculate and sum multiple features to complete the dynamic feature selection and fusion of offline handwritten signatures. Finally, using dynamic feature fusion data as input and offline handwritten signature recognition results as output, a generative adversarial network model is constructed to complete the recognition of offline handwritten signatures. Experimental results show that this method can complete the recognition of 200 offline handwritten signatures in 0.66 seconds, with an error rejection rate and error acceptance rate of only 1%, and a recognition accuracy rate of 95%.
