Apple explains Face ID on iPhone XApple shows how its new facial recognition technology, Face ID, works.
The iPhone X, your iPhone is locked until you look at it and it recognizes you. Nothing as ever been simpler or natural and effortless. We call this Face ID. [APPLAUSE] To make Face ID possible took some of the most advanced technology we've had ever created. And much of it is packed right up here into this tiny little area at the top of the display. We call this the TrueDepth camera system and it is made up of incredible state-of-the-art technology. There's an infrared camera, a flood illuminator, a front side camera and a dot projector. And that's not all. There's also the proximity sensor, the ambient light sensor, the speaker and microphone all packed into this [INAUDIBLE] camera system area. It is amazing. And here's how it works. Every time you glance at your iPhone X, it detects your face with a flood illuminator. Even in the dark. The IR camera takes an IR image. The dot projector projects out over 30,000 invisible IR dots. [BLANK_AUDIO] We use the IR image and the dot pattern and we push them through neural networks to create a mathematical model of your face. And then we check that mathematical model against the one that we've stored that you set up earlier to see if it's a match and unlock your phone. And this all happens in real time, it all happens invisibly. You don't see these things going off. It's incredible, it just all works, it all happens. When you set up Face ID, you just follow the on screen instructions. And it tells you how to move your head around in the camera. So FaceID can recognize your face. And that's it, you do that once when you set it up. And FaceID learns your face. Even if you change your hairstyle, you decide to put on glasses, you're wearing a hat, so you do it up anyway you do it, Face ID learns your face, it learns who you are and it adapts to you as your face changes over time. Let's say you start to grow a beard. It works at day, at works at night. The data for touch ID has been 1 in 50,000. Meaning that the chance that a random person could use their fingerprint to unlock your iPhone Has been about 1 in 50,000. And it's been great. So what are the similar statistics for Face ID? 1 in a 1,000,000. [APPLAUSE]
