Summary: 
Tamper proofing is a crucial problem in the watermarking application. Aiming at the credibility of multimedia, we present a semi-fragile watermark based on the image permutation. Watermarking detection is performed without resorting to the host image and it is only controlled by secrete keys, thus the whole scheme does not have certain security gaps. The simulation experiments show that it can survive the JPEG compression and effectively specify the region of the image that has been modified maliciously.
