An Eccentric Scheme for Oblivious Communication

Khan Farhan Rafat and Muhammad Sher

Trust is the foremost requirement in any form of communication. Building trust through physical contact, gesture etc. is easy but hard to establish in electronic data communication as one cant be sure of the presence of the intended recipient at the other end. This necessitated the need to devise and suggest covert schemes for oblivious communication that only the intended recipient may unveil. Steganography is one such technique where information to be sent is seamlessly superimposed on the carrier such that it easily crosses the information confronting barriers without detection. This paper endeavors at evolving a data hiding scheme envisaged by Shannon and in adherence to Kerchoffs principle that hides secret information inside statistically random English alphabets appearing as cryptogram. Effect of bit embedding is computed through contrasting probability distribution of cover text and stego object.

Keywords: Information Theoretic Security, Cryptogram, Trust, Oblivious Communication, Steganography.
