An Effective Text Steganographic Scheme Based on Multilingual Approach for Secure Data Communication

Nowadays, as communication through different internet mediums is increasing rapidly, information security is a huge concern among people of all backgrounds. Text steganography is the method of ensuring data security by concealing any secret message using cover media in such a way that no naked eyes can identify the modification of cover texts. This paper proposes a Bit-Level Embedding Technique, a variant of text steganography, to hide secret messages in the cover medium by manipulating the white spaces available in a text medium and utilizing various Latin alphabets while assuring its confidentiality not attracting suspicion from its appearance. Finally, several experiments and comparisons have been conducted to demonstrate the superiority of the proposed scheme in terms of embedding capacity, invisibility, robustness, and security that make this a standard text steganographic method. The authors propose a data hiding technique where 5-bit can be embedded per embeddable location, which is very rare in text steganography, and the utilization of multilingual forms of English alphabets gives this technique a superior performance.
