Fragile watermarking self-embedded authentication algorithm of color image

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.
