New Security System Identifies People by Unique Eye Movements

As reported by Technology Review, a company in Israel has developed a security system that identifies people based on unique patterns of eye movements. An eye-tracking system has the potential to be harder to fool and easier use, its creators say.

The new system tracks the way a person's eye moves as he or she watches an icon roam around a computer screen. The way the icon moves can be different every time, but the user's eye movements include kinetic features—slight variations in trajectory—that are unique, making it possible to identify people.
