We implemented the algorithm used to detect Tap-Wave-Rub’s wave gesture following the instructions in . Whenever the user wants to make a phone call, Tap-Wave-Rub asks her to perform a wave gesture, if the wave gesture is not detected within 10 seconds Tap-Wave-Rub does not allow her to make the phone call.
In our attack, SMASheD records a valid wave gesture and replays it. SMASheD was able to deceive Tap-Wave-Rub successfully.
