英文摘要	In this paper, we propose a novel scheme for protecting biometric templates using salient region-based authentication watermarking. Firstly, a novel multi-level authentication watermarking scheme is proposed, which is used to verify the integrity of biometric image. Secondly, the PCA features of these biometric images is used as information watermarks to recover the tampered image. Authentication bits and information bits are adaptively embedded into the biometric images based on the result of salient region detection. Experimental results show that our proposed scheme can detect the tampered region, and recover the biometric features while keeping recognizing quality.
