Using Transcoding for Hidden Communication in IP Telephony
Wojciech Mazurczyk, Pawel Szaga, Krzysztof Szczypiorski
The paper presents a new steganographic method for IP telephony called TranSteg (Transcoding Steganography). Typically, in steganographic communication it is advised for covert dat…
Understanding BitTorrent Through Real Measurements
Wojciech Mazurczyk, Pawel Kopiczko
In this paper the results of the BitTorrent measurement study are presented. Two sources of BitTorrent data were utilized: meta-data files that describe the content of resources sh…
Is Cloud Computing Steganography-proof?
Wojciech Mazurczyk, Krzysztof Szczypiorski
