All those random taps on your touchscreen display might not be so random after all. There could be a pattern to it. The way you interact with it is so unique that the researchers from Georgia Tech have created a software that can lock down your tablet if someone else is using your machine.

The LatentGesture system constantly monitors how a user interacts with a touchscreen device. And over time, it can generate a "touch signature" for them. If someone foreign uses your machine, the system will spot the difference in the movements. After that it gets locked down.

The system has been found to be nearly 98 percent accurate when used on smartphones and 97 percent accurate with tablets. For now, we'll have to wait if this sort of security could come to smartphones or tablets. [Georgia Tech via Pocket-lint]
