Your phone's vibration motor can turn into a microphone and give away your secrets

Choudhury and Roy wrote a paper about this. Re-arranging the applied voltage of the motor can turn the component from a speaker to a microphone. The good news is that this isn't something that can be done via remote control. Reversing the applied voltage requires someone to get into a phone and physically mess with the motor. However, it could only take a minute to set this up, soldering at "four critical junctions."
The vibrations recorded really don't sound like they can be identified. But with voice recognition software, and algorithms that replace missing frequencies, the garbled noise can be translated into the right word an amazing 80% of the time.
Click on the sourcelink to hear an actual pre-processed word captured by the vibration motor, the word after processing, and the word through a microphone. Choudhury and Roy will present their paper in Singapore later this month at MobiSys.

Really, so to be in real danger you must give your phone to one of this tech genius so they can mess around with your device and then spy you.... yep.. an everyday jeopardy.

and soon, some evil-genius will use all connected smartphone to map the whole town using sonar, and use all camera on this planet combined with ultra fast facial recognition to find any single person he want.. (yeah, its from that movie, and that movie :-/)
