Microsoft already has security through Windows 10 that allows users to log into devices with their face or their fingerprint.  Microsoft now seems to be taking things further with its recently patented iris recognition technology that could potentially be implemented into future Microsoft devices for enhanced security methods.

The patent filing details how the device will illuminate the eye from multiple angles while a the camera simultaneously captures photos of these different parts of the eye, creating distinct data points allowing it to differentiate a real eye from a photograph of an eye.  This new method of recognition should enhance security by taking extra steps to validate the data presented.

Whilst this patent filing is an interesting technical development it does not mean that it will result in production of consumer technology.
