摘要

Fragile watermarking for tamper location always parity checks the original image based on pixels. However, the method can't find the tamper in case of a pixel is tampered with even number tamper. Therefore, in this paper, a fragile watermarking algorithm based on Logistic system is proposed. This method disperses every pixel into 7 bits with different locations, then embeds the parity check bits into the LSB (Least Significant Bit) of the image in shuffled domain; As far as tamper location is concerned, the bits in shuffled domain is parity checked to obtain the tamper probability. Experiment result shows that the proposed algorithm is precise for tamper detection.
