Hollywood loves dreaming up future technologies in movie scripts, and although we may not (yet) have the beloved hovercrafts and flying cars from the Back to the Future trilogy, other flicks have proved more accurate. Remember the iris scanning seen in Minority Report starring Tom Cruise? If a new Google patent comes to fruition, that might become a reality sooner than you think.


The idea is nothing new: ever since the inception of Android people have lusted for apps that leverage iris scanning unlock, and more recently, developments to use your face and your fingerprint to unlock your phone have hit the mass market. But these solutions have average performance and can be circumvented, making them more of a gimmick than anything else.


Two Google patents hot off the presses imagine a world where special contact lenses essentially turn your eye into a fingerprint, with each person having a unique, snowflake like signature. Built in capacitive sensors would be used to ensure it?s an actual eyeball, not a fake replica, that is being scanned.


The process has three steps:

  1. Receiving light on an iris of an eye
  2. Detecting, at one or more light sensors disposed on or within a transparent lens covering at least a portion of the eye, light reflected from the light incident on the iris of the eye, wherein the light reflected comprises image data indicative of a pattern associated with the iris.
  3. Outputting an iris fingerprint based in part on the image data
