iOS 12 software reveals iPads are getting facial recognition


Face ID uses a TrueDepth front-facing camera on the iPhone X, which has multiple components. 

A Dot Projector projects more than 30,000 invisible dots onto your face to map its structure.

The dot map is then read by an infrared camera and the structure of your face is relayed to the A11 Bionic chip in the iPhone X, where it is turned into a mathematical model.

The A11 chip then compares your facial structure to the facial scan stored in the iPhone X during the setup process. 

Face ID uses infrared to scan your face, so it works in low lighting conditions and in the dark. 

It will only unlock your device when you look in the direction of the iPhone X with your eyes open.

Face ID captures both a 3-D and 2-D image of your face using infrared light while you’re looking straight at the camera.  

Five unsuccessful attempts at Face ID will force you to enter a passcode – which you’ll need anyway just to set up facial recognition. 

That requires you to come up with a secure string of digits – or, for extra security, a string of letters and numbers – to protect your privacy.

Face ID also adapts to changes in your appearance over time, so it will continue to recognize you as you grow a beard or grow your hair longer.
