Description
Summary:Digital watermarking is an active research area that has received a considerable attention in multimedia applications. For most watermark applications, it is often desired to retrieve the embedded information without access to the host data, which is known as blind watermark. Most previous blind watermark schemes either suffer significantly from host data interference or require expense of storage. Therefore, a simple and effective blind watermark scheme is needed urgently. In this paper, we attempt to resolve the problems. Here, we present two general blind watermark schemes, based on the lattice principle and property of periodic function, respectively. By using these schemes, the host data interference is eliminated entirely and only a little storage cost is needed. Thus, they have considerable advantages over previously proposed schemes.
