Abstract

This paper presents a new compound image watermarking method, embedding both robust watermark and fragile watermark to one image, so that it can not only convey the ownership but also justify whether the source image is tampered. Firstly, the robust watermark is embedded in the intermediate frequency of DDWT and SVD of the original image. Next, the fragile watermark is adaptively embedded into spatial domain. Simulation results show that the algorithm presented is very effective and can be widely used in practice.
