Data hiding methods can be used by intruders to communicate over open data channels (Wolf 1989; McHugh 1995; deVivo, deVivo et al. 1999), and can be used to overcome firewalls, and most other forms of network intrusion detection systems. In fact, most detection systems can detect hidden data in the payload, but struggle to cope with data hidden in the IP and TCP packet headers, or in the session layer protocol. This paper contains proposes a novel architecture for data hiding, and presents methods which can be used to detect the hidden data and prevent the use of covert channels for its transmission.
