| 摘 要： | 现有的基于空域的最不重要位（Least Significant Bit,LSB）水印算法缺乏抵抗几何攻击的能力,例如将嵌入水印后的图像旋转微小的角度就会导致水印检测的失败。为了提高空域的LSB水印算法抗几何攻击的能力,提出了1种基于LSB的抗旋转攻击鲁棒性数字水印算法。通过仿真实验证明该算法对于旋转的几何攻击具有良好的检测精度,并且整个算法实现简单,嵌入的水印数据容量大,是1种简单可靠的数字水印算法。

| Abstract: | The existing digital image watermarking method based on LSB in spatial domain without resisting to geometric attack ability,for example,the image is rotated by little angles and the author could not detect watermark.In order to improve the LSB digital image watermarking method against rotation attack ability in spatial domain,the paper proposes a digital image watermarking method against rotation attack based on LSB.Experimental results show the superiority of the proposed method for rotation attacks,meanwhile,our method is accomplished easily and embeded data information is larger,which is a simple and credible digital waternarking method. |
