Use your eye to authenticate...

Windows 10 uses bio-metric signature of an individual as a security feature of a Windows 10 device, be it a Windows Phone or a Windows tablet/PC. Windows Hello makes this possible in Lumia 950 with an iris scanner. It can also be of two other types and some devices may have more than one type. As an alternative the device should also have the option of other non-bio-metric of authentication such as a pin or a username/password pair.

Lumia 950, the Windows 10 phone has an iris scanner built-in to the camera that compares an individual's iris image to the one that it stored during the initial set up and the phone is unlocked when there is match. if not, the phone asks for the pin number to be punched in to unlock.

The other Windows Hello options are finger print recognition and facial recognition.

In what follows I show some of the screen shots for setting this up on a Lumia 950 Phone. Not all types of Windows Phone has this feature.

First of all this is a high resolution photograph of a human iris from an UK site here.
It is easy to believe the iris signature is far superior to finger print if the camera is good.


Setting up Iris Recognition:

Yous start with Settings on your Lumia Phone after setting up a pin to login. In Settings look for Personalization.

There is link if you want to know more about Windows Hello. But there is a Iris(Beta) Set up button. Click the button.
You get a Welcome to Windows Hello page. You can not only unlock your phone without complex passwords but you can buy stuff from Windows Store.

Click on Get Started. The Camera becomes active and you will be asked to move closer or farther (as the case may be) so that the camera can take its standard image of your eye as shown here.

You will be asked to hold your phone in front of your eyes (I did open my eyes a little more than wider to make sure he camera got it all) as shown.

Click Next while you are holding the camera and looking into it.

Your setting up has been successful. You may do it even with your glasses on so that with or without glasses you can unlock your phone.

It did work quite well. There were a few times it did not and then I had to use my pin. But this is much better.
