改进的BioHashing指纹模板保护算法
IMPROVED BIOHASHING FINGERPRINT TEMPLATE PROTECTION ALGORITHM
摘要
Abstract
BioHashing is a widely used identity authentication scheme in cancelable biometric authentication.For the leak of the user token causing serious degradation problems of BioHashing recognition performance,an improved algorithm BioHashing fingerprint template protection algorithm is proposed.This algorithm uses a sliding window producing a fixed-length binary sequence in the quantization process,and combined with the sliding window with more key space,which effectively improve the fingerprint feature of the discrimination and security.Both theoretical analysis and experimental results show that binary sequences generated by this method can not only effectively protect the original features of the fingerprint template,but improve the recognition performance of the system.关键词
