Your eyeball is your password

Interesting things brewing over at Google, where two recent patents show a push to operationalize new technology that lets you unlock a device using a retinal scan.

The process has three steps:
Receiving light on an iris of an eye
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.
Outputting an iris fingerprint based in part on the image data

A related patent looks at an encoded contact lens and its application. Perhaps the days of Google Glass will be numbered, as the fashion-conscious will quickly move right to the next, obvious step.
