For the tamper method of the same image copy-paste, a new tampering forensics scheme is proposed with the consistency of illuminant chromaticity in the three color channels, RGB, as the identification indicator of the image. The experimental results show that the detection way, which use the chromaticity consistency of different objects in the image as the(More)
A steganography detection algorithm on JPEG images-Markov detection is introduced. On the basics of Markov steganography detection algorithm, we detect many kinds of images, such as stego-images, spliced images and median filtered images and so on. The experiment results show that the improved Markov algorithm has higher detection accuracy rate for many(More)
