Fingerprints are the marks left by the friction of human fingers. Fingerprint identification compares two friction skin impressions of human fingers or toes to resolve whether the impressions may have come from the same person. Fingerprint identification is one of the biometric identification technologies. Most mainstream fingerprint identification algorithms are based on artificially predefined traditional fingerprint features, such as orientation field and singular point. However, because

After 2012, some researchers used convolutional neural networks for fingerprint identification tasks and achieved higher accuracy. However, this paper believes that the fingerprint images have relatively special curves, so the traditional convolutional neural network algorithms cannot fully extract the characteristics of the curves. Therefore, this paper proposes the siamese rectangular convolutional neural networks (SRCNN) algorithm to solve this problem. This paper presents the detailed architecture of SRCNN and experiments on NIST Special Database 4. The experimental results show that the accuracy of SRCNN is 4% higher than that of traditional convolutional neural networks on the test set. That is to say, SRCNN performs better than traditional convolutional neural networks in fingerprint recognition tasks.
