Abstract :
In this paper, a novel scheme to protect biometric templates using LBP-based authentication watermarking is proposed. Firstly, the m-LSB (a generalization of LSB) of biometric templates is set to zeros. Then, the modified biometric templates are partitioned into non-overlapping n X n image blocks. The LBP feature of these image blocks can be obtained, and the authentication watermark bits are generated from these features. A series of message patterns are generated according to authentication watermark bits. In order to resist vector quantization (VQ) attack and collage attack, each message pattern is embedded into the m-LSB of another image block which is selected by a position sequence. Theoretic analysis and experimental results have proved that the proposed algorithm maintains recognition rate in the template-based authentication system. And it not only has superior localization and security, but also tolerate low-noise pollution while keep sensitive to malicious manipulations.
