Analysis of perturbed quantization stegosystems

E. V. Razinkov, R. Kh. Latypov


Abstract: In the paper, we provide the analysis of perturbed quantization steganography applied to JPEG images. The ability of determining so-called changeable coefficients is discussed and an approach for that is proposed. This approach allows to create stegosystem that would take advantage of properties of perturbed quantization steganography but would use images in JPEG format as cover images.
