Abstract

This paper proposes a color watermarking scheme based on block-SVD and Arnold transformation. Color watermark means more meaningful information could be concealed in host image. Block-SVD has faster speed than SVD algorithm. We can adjust the block size according to the amount of the watermark to be embedded. Watermark´s pixel is buried to the maximum singular value (SV) bit of each block obtained from the block-SVD transformation of host image in each RGB channel. In order to enhance the security and the resistance to image cropping of the scheme, Arnold transformation is applied to watermark scrambling pretreatment. Experimental results show robustness of the proposed scheme against common image processing operations, such as Gaussian noise addition, low pass filtering, lossy JPEG compression, rescaling, cropping and so on.
