Hiding and Seeking Countering Moves Chi-square and extended Chi-square test rely on frequency counts. Defeat steganalysis based on frequency counts with correcting transforms. [Provos, 2001] Use remaining redundant bits to correct statistical deviations. A priori estimate for the amount of data that can be hidden safely. OutGuess 0.2 preserves the DCT frequency histogram. Chi-square tests unable to detect embedding. Correcting transform causes additional changes that amount to about 20% of the message size. Concept is general and can be applied to other statistics, too.
