Text Steganography Based on Feature Coding Method

Stegnography is a sheltered communication in which information such as text, image, audio and video is kept under shelter of another message. The message providing the shelter can also be text, image, video etc. No one except the dispatcher and projected addressee can have any idea if any sort of hidden writing exists. In this paper, we present and evaluate an approach for text steganography which is hiding text underneath text. The approach is based on feature encoding and random character generation method. Our focus is primarily on the shape of the capital alphabets of the English language and hence the algorithm has been termed as capital alphabet shape encoding method.
