Individual eye movements as a component of the human identification system

Now security systems are becoming more complex, and biometric systems have firmly taken their place in the common “ecosystem”. But it is clear that security systems, including those based on biometric identification, must constantly evolve. Fingerprint, iris - all this may not be enough. Oleg Komogortsev, a specialist from Texas State University-San Marcos, is going to create a system that would identify a person by the individual movement of the eyeball.

According to Komogortsev, such a system would be no less, and possibly more reliable, than biometric systems that use fingerprints and scan the iris of the eye. By the way, devices that scan the iris are already used in private companies, some airports.

When tracking the movement of the eyeball Komogortsev offers removes two characteristics of the eye. The first is to fix the eye at a specific point on the display. The second is the moment when the apple moves when you move your gaze from one point to another. The computer evaluates the data obtained, and determines the unique characteristics for each case, that is, for each person, including the work of the muscles of the eyeball.

As mentioned above, such a biometric characteristic should not be used by itself. The identification system based on the assessment of the movement of the eyeball has an error rate of approximately 34%. But the combined complex with an inexpensive iris scanner works much more accurately already, with a 5% probability of an error.

In the future, the developers believe, such systems can be used to determine the psychological state of a person.
