Zero-watermark; Image Authentication; High-orderCumulant.
In the most existing methods of digital watermark, in order to embedding watermark information, authors modify more or less original image data through various methods, which limit its robustness and security. In such a case, we present the method of zero-watermark, which is a novel digital watermarking technology without modifying the data of original image. In this paper, we construct zero-watermark using high-order cumulants. The experimental results show that the proposed zero-watermark technology has better performance.
