Smartphone sensors can help reveal PIN codes
Security researchers have found that data captured by smartphone sensors could help criminals guess codes used to lock the gadgets.
By analyzing data gathered by accelerometers they were able to get a good idea of the PIN or pattern used to protect a phone.
The data was useable because sensors can gather information with more freedom than apps loaded on the device.
Researchers said several different smartphone sensors could be subverted.
Dr. Adam J. Aviv, a visiting professor at Swarthmore College in Pennsylvania, carried out the attacks by using data gathered by an accelerometer on a smartphone. Typically this sensor logs phone movements in three dimensions: side-to-side, forward-and-back and up-and-down.
The data gathered as the phone is moved is often used in games to steer or guide an onscreen entity such as a car or a ball.
Working with Matt Blaze, Benjamin Sapp and Jonathan Smith from the University of Pennsylvania, Dr. Adam J. Aviv realized that the data gathered by the accelerometer could also be used to work out where someone tapped on a screen when unlocking a gadget with a PIN or pattern.

Clever, but simply holding a phone under a strong light will usually reveal where the finger tips have been.
