As more people use smart phones or tablets to pay bills, make purchases, store personal information, and even control access to their houses, the need for robust password security has become more critical than ever.
A new Rutgers University study shows that free-form gestures — sweeping fingers in shapes across the screen of a smart phone or tablet — can be used to unlock phones and grant access to apps. These gestures are less likely than traditional typed passwords or newer “connect-the-dots” grid exercises to be observed and reproduced by “shoulder surfers” who spy on users to gain unauthorized access.
