In this paper, the authors present a Novel method to detect the existence of hidden message in LSB steganography. The key element of the proposed method is the power Law: Zipf's law. The detection theory is based on statistical analysis of pixel patterns using a Zipfness measure between successive bit planes. The basic idea is that, the correlation between bit planes as well as the binary texture characteristics within the bit planes will differ between a stego image and a cover image. The seventh and eighth bit planes, and possibly others, are used to calculate the Zipf Quality (ZQ) measure.
