A Joint Source-Channel Steganography Decoding Paradigm and It's Implications on Capacity

Steganography has become extremely popular lately as a means of achieving security for many multimedia applications. However, research on stego-attack mechanisms has also kept pace with this development. Robustness to such stego-attacks usually requires a compromise in stegocapacity. In this paper we propose a joint source-channel coding paradigm for attack robustness with small overhead. We test our framework using a least significant bit based embedding algorithm and random additive attacks. Our results lead us to believe that the joint sourcechannel coding paradigm has significant potential in this area.
