This paper proposes a zero digital watermarking image algorithm using histogram invariant moments to resist geometric attacks .The construction of the watermark system for the original image is achieved by analyzing the histogram and computing the histogram invariant moments.Watermark extraction is simple,and only a few histogram invariant moments need to be calculated.The experimental results are compared with the results of the method based on the geometric moments.The simulation experiments demonstrate the proposed method is robust to rotation,scaling geometric attacks as well as to filtering,JPEG compression .so the proposed method is a simple,useful and credible algorithm.
