XORSTEG: A new model of text steganography

Staganography is the practice of hiding secret information using texts, images and audio as the cover media. But, using text as the target medium is not as easy as compared to the other target media, because of the lack of available redundant information in a text file. This paper proposes a new model of key-based text steganography. Various methods in this type of key-based steganography do not work when the cover file contained single letters and words which have the same starting and ending letter. The proposed approach works on this limitation and conceals a message, without degrading cover, by using XOR operation on the start and end letter of words of the cover.
