摘　　要：脆弱水印是图像认证的一种有效手段,基于图像内容的脆弱水印可通过水印重建被修改的图像。通过在图像最低位嵌入基于图像内容的水印,提出了一种彩色图像脆弱水印自嵌入认证算法,并进行了大量实验。实验结果表明,该算法具有较强的抗图像剪切及涂改等攻击能力。Fragile watermarking is an effective method to authenticate images. Fragile watermarking based on content of image can be rebuild altered image through embedded watermarking. A fragile watermarking self-embedded authentication algorithm of color image was applied through embedded watermarking based on content of image in the least bits of image, and lots of experiments were made, which shows that this algorithm has relatively strong ability against cut and alteration.
