Proposed eye-based biometrics hard to hack
A research team at the University of Tampere in Finland has proposed creating a biometric-based security system based on eye movement.
Through video surveillance, Martti Juhola and his team of colleagues proposed a system that would monitor “saccades”, the unique and rapid involuntary eye movements that all people make.
Saccades are quick, simultaneous movements of both eyes in the same direction. Once saccades are underway, they cannot be altered by will. A saccade is also an involuntary consequence of turning the head to one side or a sudden motion detected in one’s visual periphery.
“Saccades are probably the simplest eye movements to detect with signal analysis,” the team says. According to the team, they are the fastest eye movements and very easy to trigger by asking an individual to look at one target, and then another, on a computer screen.
Because of the unique nature of eye movements, the research team notes that it would be much more difficult to hack or “spoof” an individual’s pattern of saccades than to emulate their iris with contact lenses or their fingerprints with patterned silicone pads, or by way other forged images or prosthetics.
The research team reports that preliminary tests indicate that a biometric identity verification could be undertaken in as little as 30 seconds with 30 to 40 saccades being recorded, providing an accuracy rate of 90 to 100 percent.
Their research was published in the latest edition of the International Journal of Biometrics.

It’s claimed that saccades are unique. Is there any theoretical reason to think this is the case? And is there any evidence? A good biometric trait needs to be stable over time and highly specific to an individual. There are actually very few traits where the theory is strong; only iris comes to mind as a modality where the entropy is well explained and well modelled (it has to do with minute tears in the iris tissue that happen in the embryo). And we need evidence. It turns out that the gold standard “uniqueness” of fingerprints for instance is more folklore than science.
Writing in the most recent International Journal of Biometrics (Martti Juhola et al. “Biometric verification of subjects using saccade eye movements”. International Journal of Biometrics, 2012, 4, 317-337), Martti Juhola’s research team argues that a person’s saccades, which are involuntary eye movements, can be measured to provide an alternative secure biometric identification technology. Their hypothesis is that eye movement signals and patterns are absolutely unique to each individual.
Thanks for the reference!
