Improving the Perturbed Quantization Steganography by Modified Matrix Encoding
Perturbed Quantization (PQ) and Modified Matrix Encoding (MME) are two efficient embedding methods for JPEG steganography, in which the sender uses the side infor - mation of quantizing procedure of DCT coefficients to mini - mize the embedding distortion. In this paper, we propose a novel embedding method which can be viewed as a generalization of the MME to utilize the quantizing information by combining the PQ and the MME method. Experimental results show that the proposed method can achieve stronger security by keeping lower average distortion for the whole cover image than the PQ and introducing less large distortion in local than the MME.
