Sui Xin-guang, Luo Hui · 2006
Space-steganography is a method using texts to hiding secret information, which embeds invisible space characters into texts to camouflage messages. This paper anatomizes the differences of statistical features between stego-texts and natural texts by modeling the latter. A steganalysis method is designed based on the distributing of the space characters according to the differences. The method is easy to achieve, and experiments prove the efficiency and reliability of the method
