A compression-based text steganography method

► In the present study, LZW data compression based text steganography method has been proposed. ► Capacity, one of the main problems of steganography, has been increased to 7.042%. ► By employing stego keys and Combinatorics-based coding security of the proposed method has been supported. ► One advantage of the proposed method is not being language specific and protecting the originality of cover text. ► Cover texts have been generated naturally, so they do not raise suspicion and the method is resilient against the possible attacks.
