A lattice based general blind watermark scheme

Abstract

Digital watermark is a very active research area that has received a considerable amount of attention in many multimedia applications. For most watermark applications, it is often desired to retrieve the embedded information without access to the host data; this is known as blind watermark. Most of previous blind watermark schemes either suffer significantly from host data interference or require expense of storage. Therefore, simple and effective blind watermark scheme is expected urgently. In this paper, we attempt to resolve the question. Here, a lattice based general blind watermark scheme is proposed. The host data interference is eliminated entirely and only a little of cost of storage is needed. Thus, it has considerable advantage over previously proposed schemes. Experimental results demonstrated the power of this scheme. © Springer-Verlag Berlin Heidelberg 2003.
