A Survey of Multimodal Biometric Recognition Based on Hand Vein

Biometrics contain rich personal identity information, so biometrics technology has become a critical identification method. Currently, the disadvantages of single-modal biometric recognition technology in application universality and recognition accuracy have become increasingly prominent. In contrast, multi-modal biometric recognition technology integrates several complementary biometric, which expands the scope of biometric identification and improves the accuracy and security. In this paper, we mainly review the previously published view points, summarize and analyze the biometric recognition based on hand veins, and introduce fusion methods at different fusion levels.
