New Biometric
Eye movements instead of eye structures.
The new system tracks the way a person’s eye moves as he 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 him.

A lot of these newer behavioral identifiers make me wonder if they have studied them enough to determine how they will vary over time. I guess an “expiring biometric” has it’s uses.
