Concept and Application of Zero-Watermark

Abstract

In the existing method of digital watermark,for embedding watermark information,authors modify more or less original image data through various methods to limit its robustness and security.Zero watermark is a new digital watermarking technology without modifying the data of original image.In this paper,we construct zero watermark using high order cumulants.The result of experiment shows that this zero watermark constructed by this method has good performance.
