A Biometric Templates Secure Transmission Method Based on Bi-layer Watermarking and PKI
In this paper, a novel framework combining bilayer watermarking and PKI for biometric templates secure transmission is proposed. We design a novel bilayer watermarking algorithm. At the first-layer, DCTbased blind data hiding algorithm is employed. At the second-layer, the employed watermarking algorithm is public to all receivers and removable. The encrypted biometric templates and signature of biometric templates appended encrypted secret key are used as dual watermark, which are embedding into the same host image. Experimental results show that the bi-layer watermarking does not affect each other, and the proposed scheme has good performance while transmitting biometric templates over a noisy network.
