A Wavelet-Based Method of Zero-Watermark
基于小波变换的零水印算法

In order to protect the copyright of the image,this paper brings forward a image non-watermarking method based on DWT,where methods of classical Cryptology is employed.A series of experiments have been cavried out and the results proved that the presented method has much better robustness comparing with another watermark method,and the method is further broaden to hide any other digital image information besides watermark.
