The design of both steganography and steganalysis methods for digital images heavily relies on empirically justified principles. In steganography, the domain in which the embedding changes are executed is usually the preferred domain in which to measure the statistical impact of embedding (to construct the distortion function). Another principle almost exclusively used in steganalysis states that the most accurate detection is obtained when extracting the steganalysis features from thedoi:10.1117/12.2035178 dblp:conf/mediaforensics/HolubF14 fatcat:h6blnokfhjcrxi2vkwgzvxxs2u
