摘要：In this paper, we present a simple and novel approach for steganography through transliteration. A phonetic keyboard layout is very popular for writing languages having non-roman alphabets. Bengali, a language spoken by 230 million people, is a fair example and in this work we utilize Bengali digital text for data hiding by the proposed technique. For several characters in the Bengali alphabet, there are multiple options to represent a character in it’s equivalent roman form using a phonetic keyboard layout. The main idea of the proposed method is to exploit this special feature of Bengali phonetic keyboard layouts to hide secret information in form of bits. One of these options can be used to represent the bit ‘0’ and the other option can represent the bit ‘1’ in a document without any risk of understanding by any intermediate user. The results show that the proposed method is very prominent to be a successful steganography technique. Steganalysis results show that the capacity of the method is 1.2%, which is adequate for a text steganography system with very low risk of machine detection. This method can be easily adapted and applied for any other language having non-roman alphabet.
