Smartphone sensors could give away secret data; heres what new study found

In a shocking result from a study carried out by an Indian origin scientist, data from a smartphone sensors can reveal PINs and passwords to hackers and allow them to unlock the mobile devices.

It emerged that the instruments in smartphones such as the gyroscope and proximity sensors represent a potential security vulnerability, said researchers from Nanyang Technological University (NTU) in Singapore.

Using machine learning algorithms and a combination of information gathered from six different sensors found in smartphones, researchers succeeded in unlocking Android smartphones with a 99.5 percent accuracy within only three tries.

This scenario was possible only when tackling a phone that had one of the 50 most common PIN numbers.

Led by Shivam Bhasin, NTU Senior Research Scientist, researchers used sensors in a smartphone to model which number had been pressed by its users, based on how the phone was tilted and how much light is blocked by the thumb or fingers.

Known as deep learning, the classification algorithm was able to give different weightings of importance to each of the sensors depending on how sensitive each was to different numbers being pressed.
