An optometrist in Australia has discovered a way for us to use our tears as the world’s first true ‘biometric pin’, with the possibility for future development of advanced security systems via eye scans using our smartphones. So no… we don’t have to cry on them..lol. Tears change our eyes in ways that cannot be copied, giving them the potential to be used in the perfect biometric security system.
Instead of using our fingerprints or an eye scan using the iris, we could soon be using security scanners that instead focus on the tears that continually coat our eye balls created by the cornea. According to optometrist Stephen Mason, our tears are unique enough to be used to guard our most private information via an eye scan.
“The corneal surface is wet with tears so our own data changes from moment to moment,” he said. “Each data set I capture from any eye has these really tiny variations.”
This kind of technology could be employed for online payments, encrypted emails or simply to secure your phone. Each person’s cornea has a unique map which which continually changes, so the scanner will expect and predict a different scan result each time, making it virtually impossible to replicate. With the digital age we live in maturing at exponential speeds, the race in on to find a definitive security system that can replace today’s password driven systems. Biometric scanning like the one involving tears, could be the key the future on security.
