Text Steganalysis Method——Breaking Steganographic Utility of Stego
Shiyao Jin · Jisuanji gongcheng · 2006
Stego is a steganography software using text to hide secret information.It transforms any binary file into nonsense text based on a dictionary either given explicitly or built on the fly from a source document.By studying the mechanism of Stego,this paper proposes two steganalysis methods to detect it.When the first letters of words in dictionary are lowercases,the steganalysis method based on the signature characters is used to detect Stego;When it’s not in above condition,the steganalysis method based on statistical characters is used to detect Stego.The results of experiments show that the two methods have high credibility.
