Syntax Bank and HMAC based Syntactic Steganography Approach for Information Security
Wai, Ei Nyein Chan
Khine, May Aye
Steganography plays an important role forinformation security in today digital age.Because of the widespread usages of naturallanguage, we propose a linguisticsteganography approach based on syntax bankand HMAC in this paper. The proposed systemfirst uses the combination of most popular twolossless data compression methods to compressthe input secret message. At the same time, thesystem extracts the syntax of the incoming covertext sentence. Then, syntax set creation taskconstructs the syntax set of the given sentencewith the help of the syntax bank. The syntaxtransformation step then transforms the inputsentence into a desired syntax that canrepresent the key-controlled semi-randomlygenerated secret bits intended to hide in thesentence. In addition, we apply SHA 512 hashalgorithm to generate keyed-hash messageauthentication code (HMAC) in order to presentthe identity of the resulting stego text. Theresulting stego text will still be innocent-lookingby applying semantically unchanged syntaxtransformation on the input text. Thus, thedetection of the secret message may be hard forthe intruder.
