| 摘 要： | 该文提出了一种基于独立分量分析(Independent Component Analysis,ICA)的能有效抵抗拷贝攻击的数字水印方案。该方案将能够唯一描述原始图像的图像签名与数字水印一同嵌入到原始图像中,并采用ICA技术进行检测。通过验证签名,可以判断待测图像是否合法,从而实现抗拷贝攻击的目的。计算机仿真结果证明了该方案的有效性和鲁棒性。

| Abstract: | A digital watermarking scheme is proposed in this paper, which is based on Independent Component Analysis (ICA) and able to resist copy attack effectively. In this algorithm, both the image signature describing the original image uniquely and the watermark are embedded into the original image synchronously and extracted through ICA techniques. By comparing the re-calculated signature of the marked image according to the image signature algorithm with the extracted one, the legality of the marked image can be determined and the purpose of resistance to copy attack can also be realized. Simulation results demonstrate the robustness and validity of this proposed method. |
