We propose an algorithm which can locate tampered region(s) in a lossless compressed tampered image when its unchanged region is output of JPEG decompressor. We find the tampered region and the unchanged region have different responses for JPEG compression. The tampered region has s

Anforderungen an die Strafverfolgungstogram, here we consider the additional ingredient of resisting additive noise-like operations, such as Gaussian noise, lossy compression and low-pass filtering. In other words, we study the problem of the watermark against both TSM and additive noises. To this end, in this paper we extract the his

We tested the proposed algorithm against nine types of attacks like JPEG compression, Gaussian Noise addition, Median Filtering, Salt and Pepper noise, etc. They are carried out usi
