A Comparative Review of Steganalysis Techniques
Qian Tu, Sathiamoorthy Manoharan · 2015
While Cryptography is the science of secure communication, Steganography is the art of covert communication. Steganography has a long history, but modern steganography uses digital carriers such as electronic text, disk space, network packets, digital audio and images to hide secrets. Steganalysis, the countermeasure to steganography, is designed to detect and analyse the hidden data disseminated using steganography. This paper reviews and compares three steganalysis techniques: the Histogram Characteristic Function (HCF) technique, the Regular-Singular analysis (RS) technique, and Raw Quick Pair (RQP) technique. The paper analyses the performance, characteristics, and limitations of these three techniques, supported by empirical evidence.
