摘要
根据LSB算法的基本原理利用Matlab7.0将特定的水印信息嵌入到给定的数字图像中,并编制出提取水印的程序进行水印的提取。然后将嵌入水印的图像进行旋转、缩放、裁切等攻击,通过提取受攻击图像的水印信息来检验用该算法的鲁棒性。实验结果表明,此方法得到的数字水印对于剪切、缩放和噪音的攻击,具有较好的鲁棒性。
Watermark information was embed into given image using MATLAB according to the arithmetic of least significant bit. Watermark extraction program was programmed. The watermarked image was attacked with rotating, resizing, and cutting. The robustness of the arithmetic was validated with the watermark information extracted from the attacked image. The results showed that the watermark has excellent robustness to rotating, resizing, and cutting.
