Classification: CPC G  H | IPC G  H

Claim 11:
12. A system for receiving and processing a covert transmission within a TCP/IP protocol stack, said system comprising:
a transmitting computerized system operating the TCP/IP protocol stack and a covert data transmission routine; and
a receiving computerized system operating the TCP/IP protocol stack, a covert interception routine inserted as an extension of at least one of the IP protocol layers of the TCP/IP protocol stack, and a covert processing routine, wherein said receiving computerized system is connected to the transmitting computerized system by way of one or more TCP/IP networks;
wherein said transmitting computerized system is configured to generate a datagram using the covert data transmission routine by including covert data within the datagram with at least one or more inaccurately described features which prevent normal processing through the TCP/IP protocol stack at the receiving computerized system;
wherein said receiving computerized system is configured to:
receive network traffic by way of the one or one or more TCP/IP networks, said network traffic including said datagram;
process said network traffic, including processing the network traffic through the TCP/IP protocol stack, intercepting said datagram at the covert interception routine and processing said datagram through the covert processing routine to extract said covert data, and subsequently resume processing of the datagram through the TCP/IP protocol stack, including discarding the datagram as a non-conforming data transmission at the IP layer due to the one or more inaccurately described features.
