A Secure Steganographic Method via Multiple Choice Questions
Lingyun Xiang, Xingming Sun, Yuling Liu and Hengfu Yang

Abstract: In this study, a novel secure steganographic method was proposed by taking advantage of Multiple-Choice Questions (MCQs). Selecting a series of MCQs to automatically generate a stego text could conceal secret information. The proposed method could achieve a considerable embedding bit rate while being able to hide more information by reordering the options of the generated MCQs. The final outputting stego texts were kept the same linguistic and statistic characteristics as normal texts, thus the hidden information had good imperceptibility and could survive under potential steganalysis attacks, which was also demonstrated by experiments. More experimental results showed that the average embedding bit rate achieved more than 1 bit per sentence, which was superior to the bit rate of most existing linguistic steganographic methods.
