Abstract

This paper presents a chaotic watermarking scheme for copyright protection. The proposed method employs the singular-value-decomposition (SVD) based watermarking scheme and the encrypted watermark based on the chaotic maps. The rightful owner possesses two secret keys: one related to the owner, another to the original image. Chaotic maps are used with the keys for watermark encryption so as to enhance the anti-counterfeit and noninvertibility properties of the watermark. Examples are illustrated to demonstrate the robustness and security of the proposed watermarking scheme.
