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.
