Hiding Packets in VoIP Chat

Posted by CmdrTaco on from the because-you-can dept.

holy_calamity writes "Two Polish researchers say they have developed a system to hide secret steganographic messages in the packets of a VOIP connection. It exploits the fact that VoIP uses UDP, not TCP; it is designed to tolerate some packets going missing -- so hijacking a few to transmit a hidden message is not a problem."

    Steganography (as contrasted with cryptography) is the art/technique of hiding secret messages within other seemingly innocuous messages -- i.e., invisible ink or Neal Stephenson's example of coded binary weave patterns within a character's crocheting (in his novel "The Confusion").

    As the previous poster mentioned, with encryption third parties know there is a message, but they might not necessary know with a hidden message of this kind.
