A Robust Watermark Scheme for Copyright Protection

초록

영어

In this paper, we propose a robust watermark technology to protect copyright. We enhance robustness of the watermark such that it can be used to protect the intellectual property even after serious attacks on the watermarked image. In the proposed watermarking, we embed watermarks by Singular Value Decomposition and Distributed Discrete Wavelet Transformation techniques. Regarding our method, Singular Value Decomposition provides the robustness to protect the image from most attacks except cropping, while Distributed Discrete Wavelet Transformation disperses watermarks all over the image to resist cropping attacks. The robustness of our proposed watermark scheme has been verified experimentally against main kinds of watermark attacks such as geometric and signal processing attacks.
