There used to be a name for a technology (or way of implementing technology) to prevent electronic eavesdropping.
It's called white noise. You need real random to produce real white noise. Another solution is to use microphones and produce inverted sound waves to "cancel" sound. It can be done. White noise is cheaper but if your random source is not really random, it can be circumvented. Think of the quality of random you need the same one as required to have a proper implementation of OTP ciphers. -- unzip ; strip ; touch ; grep ; finger ; mount ; fsck ; more ; yes ; fsck ; umount ; sleep
