Most of recently image watermarking algorithm is based on image texture analysis. In practice, content and taste of observer are very important information for determining embedding points. This paper presented a novel digital image watermarking algorithm based on content sensitivity analysis in. Developed a new method which successfully combines the characteristics of singular values and variances to measure the activity of sub-blocks of the host image. The application of the proposed embedding scheme mades the wtermark capable of blind-extraction. Presented one new means named ICSP-PSNR to evaluate host image’s quality based on content. Simulation results show that the method performs better than traditional methods and fulfills a good compromise between the robustness and transparency.
