Although real host signals are not memoryless, a decorrelating energy-preserving transform can always be applied before a method that assumes a memoryless source, as is usually done in the dual problem of source coding. A further constraint is needed in practice: the information-carrying signal must be close to the host, according to some distance measure. Thus steganography of memoryless sources using permutation coding is a rate-distortion problem. Here we delve deeper in the study of the embedding distortion of permutation coding, and we show that the rate-distortion tradeoff for partitioned permutation coding is nearoptimum according to the Gel’fand and Pinsker capacity formula.enSteganographyDecorrelationDistortionMemoryless systemsRate distortion theorySource codingConference Publication17417910.1109/WIFS.2013.67078142013-11-11https://creativecommons.org/licenses/by-nc-nd/3.0/ie/
