Few years back I started thinking about how much information could be extracted from a phone’s inertial sensors to guess some sensitive information such as PIN / UnLock Codes / other passwords. One of the first papers a came across was (sp)iPhone: Decoding Vibrations From Nearby Keyboards Using Mobile Phone Accelerometers where the authors were able to decode strokes from a nearby keyboard using the phone’s inertial sensors.
Not until a couple months ago a started working on this more seriously, when I wrote few applications to retrieve data, started analysing and came to some conclusions. In this post, I will describe the materials & methods used so they might be handy to someone else.
