- Abstract
- In this paper, we propose a non-blind watermarking method that embeds a pseudo-random sequence (watermarks) into wavelet DC components. The DC area is not suitable for embedding because of severe visual degradation. We overcome the degradation problem by embedding watermarks into visually insensitive locations. We compare our experimental results with respect to JPEG compression with Cox & popular correlation-based method. We also compare the robustness of our technique with other methods registered in CheckMark This study reveals that the proposed method simultaneously provides good fidelity in quality as well as robustness against external attacks.
