A less benign use of smartphone sensors than Snowden's new app: "Hackers could crack your PIN number in just THREE attempts using data from motion and light sensors installed on smartphones Sensors studied the tilt of the phone and how much light was blocked by fingers Sensors included phone's accelerometer, gyroscope and ambient light sensor Technique can unlock Android smartphones with a 99.5 per cent accuracy The previous best phone-cracking success rate was 74 per cent, study claims..." To avoid this type of technique, the advice is to restrict access to phone's sensors. http://www.dailymail.co.uk/sciencet...e-attempts.html?ito=social-twitter_mailonline
