Abstract

Online Signature Verification (OSV), as a personal identification technology, is widely used in various industries. However, it faces challenges, such as incomplete feature extraction, low accuracy, and computational heaviness. To address these issues, we propose a novel approach for online signature verification, using a one-dimensional Ghost-ACmix Residual Network (1D-ACGRNet), which is a Ghost-ACmix Residual Network that combines convolution with a self-attention mechanism and performs improvement by using Ghost method. The Ghost-ACmix Residual structure is introduced to leverage both self-attention and convolution mechanisms for capturing global feature information and extracting local information, effectively complementing whole and local signature features and mitigating the problem of insufficient feature extraction. Then, the Ghost-based Convolution and Self-Attention (ACG) block is proposed to simplify the common parts between convolution and self-attention using the Ghost module and employ feature transformation to obtain intermediate features, thus reducing computational costs. Additionally, feature selection is performed using the random forest method, and the data is dimensionally reduced using Principal Component Analysis (PCA). Finally, tests are implemented on the MCYT-100 datasets and the SVC-2004 Task2 datasets, and the equal error rates (EERs) for small-sample training using five genuine and forged signatures are 3.07% and 4.17%, respectively. The EERs for training with ten genuine and forged signatures are 0.91% and 2.12% on the respective datasets. The experimental results illustrate that the proposed approach effectively enhances the accuracy of online signature verification.
