Abstract :
In this paper a new compression-based method for estimating LSB replacement rate in color and grayscale images is introduced. We compare this method experimentally with the state-of-the-art improved WS steganalysis. The results of our experiments show that depending on the archiver the new method can be more effective than improved WS steganalysis for noisy color images.
