Secure Fingerprint Authentication Using a Robust and Effective Biometric Cryptosystem
摘要
The security offered by biometric technology plays a crucial role in its reliability and acceptance, which is hampered by the leakage of biometric templates and undermines the user’s privacy. This eventually causes permanent identity loss for a user. To overcome this issue, we propose a robust template protection technique for fingerprint user templates based on a Fuzzy Commitment Scheme (FCS). The original template is binarized by utilizing a modification of Binarized Phase Spectrum (BiPS), which is a binary string of fixed-length extracted by quantization of the phase spectrum computed from the minutiae set. Further, the generated binary template is secured by utilizing the FCS. To align the fingerprint images, a Principal Component Analysis (PCA) based technique has been utilized. The proposed technique achieves the FRR of 16.05%, 9.1%, and 4% on FVC2002 DB1 employing FVC protocol, enrollment of two images, and 1-vs-1 protocol, respectively, at zero FAR.
