Title: Keystroke Acoustic Emanations

Abstract: Researches shows that PC keyboards, notebook keyboards and ATM pads are vulnerable to attacks based on subtly different sound emanated by different keys, so it is possible to recover the text based on the keystroke sound. What is more, the typed text is always not random, English words spelling and grammar limits character combinations. This talk will present a novel attack on a recording of one typing English text using a keyboard, making use of time-FFT features, Hidden Markov Model and linear classification.
