Blocking Steganosonic Data In Phone Calls 185
psyced writes "Steganography is a technique to encode secret messages in the background noise of an audio recording or photograph. There have been attempts at steganalysis in the past, but scientists at FH St. Pölten are developing strategies to block out secret data in VoIP and even GSM phone calls by preemptively modifying background noise (link is to a Google translation of the German original) on a level that stays inaudible or invisible, yet destroys any message encoded within. I wonder if this method could be applied to hiding messages in executables, too."

Yes, a similar method has been employed by Microsoft to all the executables it ever released, ever since the times of MS-DOS.
After compilation they run the program through a special utility that modifies a few bits in the executable at random. Then they run the resulting executable through some tests and if it passes, they release it, if it crashes, they try with a different random bits.

Please clarify immediately. Is that just a repetition or does the butterfly flap its wings four times. This could be the difference between a gang of naked teenagers invading Prime Minister's question time and the defacing of Nelson's column.

Yes, but how to do this in real-time in a cryptographically secure manner is the subject of much ongoing research.
The feeling in the research community at the moment is that efficient stego-redundancy requires a working database of discovered steganographic synonyms, i.e. a stegosaurus [wikipedia.org].

Just need to check because that looked like one of the secret code words I am supposed to be watching out for, anyway if that is you Francis ( there is a code word for this somewhere but I think it's in the basement somewhere so I'll just give you the gist ) the "materials", you know what I mean eh - one ends the barrel and they're "easily triggered", anyway the "materials" will be loaded onto the Builders Merchants truck which will then be parked on Lincoln Street, outside the curry house ( quite a nice one actually I have an account there the food is delicious ) where you can go and "steal it". The keys will above the wheel. Usual time, tomorrow 11:25AM.
Remember, absolute secrecy is required. One false word and all will be blown.

PS, this e-mail system of yours is great. All that nonsensical spam you fill it with is bound to throw off the man if he comes a looking. Good work.
