A novel robust zero watermarking scheme based on DWT and SVD

摘要：

In this paper, we proposed a novel watermarking scheme for image authentication based on discrete wavelet transform (DWT) and singular value decomposition (SVD). Different from the developed SVD-based watermarking schemes where the singular values are slightly modified, our scheme constructs the watermarks from the singular vectors which specify intrinsic geometry properties of images. Within the framework of zero watermarking, the watermarks are registered in a third-part intellectual property rights (IPR) database for copyright protection. Experimental results show that the proposed scheme is robust not only to common image processing operations, but also robust to local geometric distortions.
