A promising concept is being tested by the researchers at the Stanford University which can change the way we enter our sensitive data like passwords, ATM PINs in public places. This revolutionary system coined as EyePassword, helps a user to enter their data by gazing on the onscreen keyboard and the system detects what text you want to insert. It’s not some magic but it works by a camera which monitors the user’s eyes.
In their words – One or more infrared light sources illuminate the user’s face and produce a glint – a reflection of the light source on the cornea. As the user looks in different directions the pupil moves but the location of the glint on the cornea remains fixed. The relative motion and position of the center of the pupil and the glint is used to estimate the gaze vector, which is then mapped to coordinates on the screen plane (keyboard).
The researchers claim that presently the eye tracker devices are pretty expensive but as the R&D costs are covered by these companies, they are bound to reduce. Undoubtedly, EyePassword can be a secure way of inputting secure data as it does not involve user’s physical movements but just the eye movements.
