Eavesdroppers can decipher typing sound...

Listen to this: Eavesdroppers can decipher what is typed by simply listening to the sound of a keystroke, according to a scientist at this week's IEEE Symposium of Security and Privacy in Oakland, Calif.

Each key on computer keyboards, telephones and even ATM machines makes a unique sound as each key is depressed and released, according to a paper entitled "Keyboard Acoustic Emanations" presented Monday by IBM research scientist Dmitri Asonov.

All that is needed is about $200 worth of microphones and sound processing and PC neural networking software.

Interesting, but kind of crappy really. You'd have to train on the SPECIFIC KEYBOARD you wanted to target, and even then he only got 80% accuracy. Toss in the wishful thinking of the researcher, and this doesn't look very good.

Considering that in the spy game......key strokes have been monitored for years. Each key emanates a particular frequency. The CIA and the old KGB did this to each other many years, the public is just catching up.
