A device called EyeLock, which uses iris recognition as an alternative to passwords to log you in to password-protected Web sites and applications, has been designed by the Hoyos Group.

The scanning device resembles a wand and plugs into a base that connects to your PC via a USB port.

After you install the software and choose the sites and applications that you want to iris-protect, you pass the scanner in front of your eye. A snapshot is taken of your iris to confirm your identity. If confirmed, you’re then granted immediate access to the selected secure web site or application.

“Every time you log in, it reads your iris and creates a unique key, which is a series of numbers, and this key changes every time you log in, so no one can hack it,” Tracy Hoyos, assistant marketing director, said in an interview with CNN.

EyeLock was demonstrated at a tech show in San Francisco on May 10.
