Information Security System Based on English and Myanmar Text Steganography

Abstract

Due to the growth in frequent exchange of digital data over public channel, information security plays an important role in daily part of communication. Hence, various techniques like steganography are applied in information security area for more efficient information security system. This paper proposes two new text steganographic approaches using two different languages which are based on Unicode standard for secure data transfer over the public channel. The main aim is to overcome the limited embedding capacity, suspiciousness, and data damaging effect due to modification of existing steganographic approaches. The first approach conceals a message, without degrading the cover, by using four specific characters of words of the English cover text. The second approach performs message hiding by using the three specific groups of characters of combined words in Myanmar cover text while maintaining the content of the cover. The structure and operation of the proposed approaches based on the idea of existing text steganographic technique: Hiding Data in Paragraph (HDPara) algorithm. In this work, an empirical comparison of the proposed approaches with HDPara approach is presented. According to the comparison results, the proposed approaches outperform the existing HDPara approach in terms of embedding capacity.
