Translation-Based Steganography is a secure text steganographic algorithm. In this paper, we present a novel statistical algorithm for steganalysis of Translation-Based Steganography (STBS). We first show that there are fewer high-frequency words in stegotexts than in normal texts. We then design a preprocessor to refine all the given texts to expand the frequency differences between normal texts...
Steganography is an important research direction of information security, which mainly research how to embed secret information into carriers, in order to achieve the objectives of secure communication. In this paper, a novel Chinese text steganography based on substitution of different forms Chinese characters is proposed. We propose two embedding methods named SSM and HESM. SSM simply substitute...
Translation-based steganography (TBS) is a kind of famous text steganography. In this paper, we examine the robustness of TBS and give an effective detection algorithm for TBS. Our algorithm can not only distinguish between natural language text and stego-text which was generated by TBS, but also can distinguish between machine translated text and stego-text. The detection accuracy increases as the...
Steganography is a technique for embedding secret messages into carriers. Linguistic steganography is a branch of text steganography. Research on attacking methods against linguistic steganography plays an important role in information security (IS) area. In this paper, a linguistic steganography detecting algorithm using statistical language model (SLM) is presented. An experiment to detect text...
