With the flick of an eye
Paweł Kasprowski, Józef Ober · Biometric Technology Today · 2004
The way a person moves their eyes may not at first seem like the ideal basis for performing identification, but new research shows that this biometric type could offer several advantages. For example, while the biometric is difficult to counterfeit, it is nevertheless easy for a user to use the system. Moreover, it could also be possible to combine this type of biometric with other techniques such as iris or facial recognition.
