Computerphile Dr. Mike Pound Explains How Face ID Might Work

Apple claims its Face ID technology protects users' phones by providing "intuitive and secure authentication." The extremely advanced feature can be used for everything from unlocking your iPhone or iPad Pro to authorizing purchases from the iTunes Store or payments with Apple Pay.

And when it comes to the tech that enables this tool, Apple does not hold back. "The technology that enables Face ID is some of the most advanced hardware and software that we’ve ever created," claims the tech giant's site.

"Face ID automatically adapts to changes in your appearance, such as wearing cosmetic makeup or growing facial hair. If there is a more significant change in your appearance, like shaving a full beard, Face ID confirms your identity by using your passcode before it updates your face data. Face ID is designed to work with hats, scarves, glasses, contact lenses, and many sunglasses. Furthermore, it's designed to work indoors, outdoors, and even in total darkness," continues Apple.

But how does all this work? Well, famed YouTuber Computerphile released this latest clip of his show to attempt to explain what he thinks is the secret behind Face ID. It should be noted that even Dr. Mike Pound is not entirely sure about this extremely advanced system.

However, we would venture a guess he likely got it right. Now, if only Apple would confirm our hunch.
