Description
Summary:Digital watermarks provide the capability to insert additional information onto various media, such as still images, movies and audio, by utilizing features of the content. Several methods for printed documents have already been proposed using features of the text or images. In order to overcome the disadvantages of existing methods, we have proposed a new information hiding scheme for printed documents; namely, the artificial fiber pattern by using the features of the paper instead of those of the contents. The method has features of rotational invariance and low visibility. In this paper, we improve the algorithm aimed at equipment independence and the robustness against physical attacks.
