How about hiding data in digitized audio? With enough audio the data wouldn't degrade the signal noticably.
I've already done that, it's included in the s-tools v2 package as a module to conceal information in .WAV files. The effect on quality when using the LSB of an 8 bit 11Khz mono sample is not noticeable unless the original sound is highly pure (e.g. downloaded from a synth). Even then it only shows up as _very_ faint interference that needs a good hi-fi to hear and the original sample for comparison. Regards, - Andy
