- W2393166806 abstract "In this paper,a semi-fragile watermarking scheme with self-recovery is proposed.The proposed scheme can distinguish malicious tamper from JPEG compression,and can recover the tampered region based on tamper detection result.Firstly,the image is divided into 8×8 image blocks;DCT is performed on them,and then quantize the DCT coefficients using the per-determined quality factor.The authentication watermark bits are generated from DCT coefficients and embedded into the DCT domain of the image.Experiment results demonstrate that the proposed algorithm not only has capability of superior localization and self-recovery,but also tolerate JPEG compression while keeping sensitive to malicious manipulations." @default.
