Abstract
This paper presents a secure and robust watermarking scheme to enhance the security of biometric template over insecure network. Diffusion and digital watermarking techniques are used to improve the security and secrecy of the templates. Diffusion phase is done by chaotic sequence and Hessenberg decomposition. This phase essentially change the pixel values of biometric template randomly. Finally, the watermark image, which is the face image of the owner of biometric template, is embedded in the diffused biometric template with the help of singular value decomposition. The feasibility of the proposed method and its robustness against different kind of attacks are verified by computer simulations. © 2010 Published by Elsevier Ltd.
