YouSkyde: information hiding for Skype video traffic

Wojciech Mazurczyk , Maciej Karaś , Krzysztof Szczypiorski , Artur Janicki


n this paper a new information hiding method for Skype videoconference calls – YouSkyde – is introduced. A Skype traffic analysis revealed that introducing intentional losses into the Skype video traffic stream to provide the means for clandestine communication is the most favourable solution. A YouSkyde proof-of-concept implementation was carried out and its experimental evaluation is presented. The results obtained prove that the proposed method is feasible and offer a steganographic bandwidth as high as 0.93 kbps, while introducing negligible distortions into transmission quality and providing high undetectability.
