Abstract :
This paper proposes a content based color watermarking scheme based on block SVD and Arnold Transformation [1]. The main intention of watermarking system is to meet two conflicting objectives. They are robustness and transparency. DWT is used as a feature (Content based Watermark) to embed it in the host image. The watermark´s pixel is embedded into the maximum singular value bit of each block obtained from the block SVD transformation of host image in each RGB channel. To increase the security, Arnold Transformation is used to watermark scrambling pretreatment. Experimental result shows the robustness of this scheme against common image processing operations such as JPEG compression, noise, rotation, rescaling, etc.,.
