Abstract

This paper presents steganography methods to covertly transmit data via RTP (Real-time Transport Protocol) header and RTP payload in multimedia streaming over networks. The proposed covert channels do not change the original traffic pattern. The bandwidth and the impact of the proposed covert channels on the received video quality are analyzed. Steganalysis of the proposed hiding methods is also discussed and the proposed covert channels cannot be detected by traffic pattern, received video quality, or the statistical property required by the standard. Simulations on real video traces and RTP packets collected from multicasting videos to LAN (Local Area Network) are conducted and the results show the proposed covert channels not only achieve relatively high bandwidth but also keep the received video quality high or unchanged. Those features make the proposed covert channels practical and not easy to be detected. Copyrighty
