In this paper, we investigate and discuss the biometric encryption of the finger vein to address the limitations of traditional biometric encryption. We propose a finger-vein encryption scheme based on multiscale block–center-symmetric local binary pattern (MB-CSLBP) binary coding. First, we investigate the LBP operator, the improved CSLBP, and the MB-CSLBP operator, and extract the MB-CSLBP binary code of the finger vein. Next, we investigate the traditional fuzzy commitment encryption scheme, and, with the extracted finger-vein MB-CSLBP binary codes as the encryption feature, we perform Bose, Chaudhuri, and Hocquenghem (BCH) encoding of the encryption information. Then, we combine the encryption information and encryption feature in an exclusive-OR manner, use the SHA-1 hash algorithm to perform a Hash transform, and keep the obtained Hash value for encryption. The experimental results show that the false acceptance rate reached 0.47% for a key length of 400 b. Thus, the finger-vein encryption method proposed in this paper demonstrates high robustness and security.
