Abstract. Watermarking stays the main technical safeguard of electronic copyright. This paper presents the first public-domain oblivious watermarking scheme for images which survi...
Many techniques for watermarking of digital images have appeared in numerous publications. Most of these techniques are sensitive to cropping and or a ne distortions e.g., rotatio...
A new method improving watermark robustness against both global and local geometrical distortions is presented in this article. The proposed approach is based on a self-reference c...
-- Digital Watermarking is used for copyright protection and authentication. In the proposed system, a Dual Watermarking Scheme based on DWT-SVD with chaos encryption algorithm, wi...
The paper proposes a blind spread spectrum watermarking scheme where watermark information is embedded redundantly in the multilevel wavelet coefficients of the cover image. It ha...
