|Abstract||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.|
