Wet paper codes are used to design steganographic schemes, in which the sender can embed messages into a cover with arbitrarily selected changeable bits that are not shared by the recipient. In this letter, we propose a novel approach to wet paper codes by folding the cover into several layers and applying basic wet paper coding methods with low(More)
Perturbed Quantization (PQ) and Modified Matrix Encoding (MME) are two efficient embedding methods for JPEG steganography, in which the sender uses the side information of quantizing procedure of DCT coefficients to minimize the embedding distortion. In this paper, we propose a novel embedding method which can be viewed as a generalization of the MME to(More)
