Abstract
In this paper, we study how specific design principles and elements of steganographic schemes for the JPEG format influence their security. Our goal is to shed some light on how the choice of the embedding operation and domain, adaptive selection channels, and syndrome coding influence statistical detectability. In the experimental part of this paper, the detectability is evaluated using a state-of-the-art blind steganalyzer and the results are contrasted with several adhoc detectability measures, such as the embedding distortion. We also report the first results of our steganalysis of the recently proposed YASS algorithm and compare its security to other steganographic methods for the JPEG format.
