Researchers from Polytechnic Institute of New York University have developed multitouch gesture-based applications for logging into smartphones, tablets and other mobile devices. Instead of text typed passwords, they propose biometric authentication: your hand size, finger placement, and speed of movement can serve as a unique signature for login applications.
Professor Nasir Memon explains that we should make better use of touch interfaces. A biometric information contained in a human gesture such as the finger swipe can be enough to identify a particular user and to unlock requested application.
The latest prototype designed in NYU-Poly lab constitutes of a multitouch gesture combination lock. As presented on the video above, to unlock the device, the user has to form the lock with a pinching motion, and then a circle outline appears, ready to dial a number.
According to professor Memon, such a time-sensitive gesture pattern can identify users with 96% accuracy level (as proved the study of about 100 users), and is very hard to crack. Because even if someone watched you do it, it is still difficult for anyone to replicate the biometrics of your own gesture!
