Abstract

A fragile watermarking algorithm for image contents integrity verification based on logistic system and JPEG (Joint Photographic Experts Group) is proposed in this paper. The watermarking process is carried out during JPEG quantization process. Firstly, each 8×8 DCT coefficients block is subdivided into 4 groups based on logistic system; then, in order to obtain the watermarked JPEG image, all of the groups are check coded by the check bits. The watermarked JPEG image remains high quality. The tamper probability is determined by checking the DCT coefficients groups.
