Hiding Packets in VoIP Chat 90

Posted by CmdrTaco on Monday June 02, 2008 @12:40PM 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."

Thanks Slashdot, because I really want to go to Slashdot to get links to a story that I have to pay to read.

You're welcome?

Stop this research. No way I am going to say GoodBye to my Secretary. She knows a lot more than just stenography;)

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".

I'm on to you.

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

Ha...

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!"

And since when is referring to previous relevant /. articles being a troll?
Probably just someone trying to post a steganographic message using the /. mod-system.

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.

No? How about this...

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.

Bah, nevermind.

Apparently Dell was generating documents with unique sets of typos in order to be able to track down the identify of the person who leaked a document.
Either that, or Dell has taken the 'million monkeys at a million keyboards' approach to producing technical manuals!
