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."

    I assumed the misspelling was one part of a larger steganographic message. Let it be known that I am now browsing over your comment history looking for further "mistakes".

    If you want to hide packets over VoIP I suggest making "beeping" noises.

      A Polish guy goes in for his yearly eye examination.
      The eye doctor says, "OK, read the smallest line down on the chart that you can."
      The guy reads out, "W... Z... P... X... Y... I... Z... Y... K...".
      The doctor says, "Wow, that's great, you can read the bottom line?"
      The Polish guy says, "Read it? Hell, I know the man!"

    Plain cryptography is something like having a locked car sitting in a room. It might not be easy to get into, but you know it when you see it. This is like having a car behind a painting. You don't notice that there is anything being kept away from you. Well, other than that big-assed painting.

    Plain cryptography is something like driving your car across the border while trying to keep from having to show your passport to the border patrol (by showing them fake ID). This is like doing the same while having the trunk full of cocaine when you do so.
