Mobile phones are equipped with an increasingly large number of precise and sophisticated sensors. This raises the risk of direct and indirect privacy breaches. In this paper, we investigate the feasibility of keystroke inference when user taps on a soft keyboard are captured by the stereoscopic microphones on an Android smartphone. We developed algorithms(More)
