Watch Face ID in Action on iPhone X with an IR Camera [VIDEO]

Shared by a user named throwawaybutnotrlly on Reddit, a cool video clip extracted from The Verge’s iPhone X review shows how the Face ID camera projects up to 30,000 IR “dots” on the face.

Here’s how Face ID securely authenticates your face, according to Apple:

Face ID is designed to confirm user attention, provide robust authentication with a low false match rate, and mitigate both digital and physical spoofing. The TrueDepth camera automatically looks for your face when you wake iPhone X by raising it or tapping the screen, as well as when iPhone X attempts to authenticate you to display an incoming notification or when a supported app requests Face ID authentication. When a face is detected, Face ID confirms attention and intent to unlock by detecting that your eyes are open and directed at your device; for accessibility, this is disabled when VoiceOver is activated or can be disabled separately, if required.

Once it confirms the presence of an attentive face, the TrueDepth camera projects and reads over 30,000 infrared dots to form a depth map of the face, along with a 2D infrared image. This data is used to create a sequence of 2D images and depth maps, which are digitally signed and sent to the Secure Enclave. To counter both digital and physical spoofs, the TrueDepth camera randomizes the sequence of 2D images and depth map captures, and projects a device-specific random pattern. A portion of the A11 Bionic processor’s neural engine—protected within the Secure Enclave—transforms this data into a mathematical representation and compares that representation to the enrolled facial data. This enrolled facial data is itself a mathematical representation of your face captured across a variety of poses.

    Apple should leave tech review to the real tech review sites like Verge, not some amature tiny fame sucking youtubers that can’t say anythting except wow, amazing, this is dope, sick.

  • My 1/2 cents

    I can’t help wonder about the health implications of this?

  • My 1/2 cents

    I guess you haven’t heard of self marketing or propaganda?

    Exactly. I am not sure if I am on board with the FaceID unlocking. Apple should have kept TouchID (maybe on the back of the device) for people who are reluctant to adopt the new technology right away without knowing the ill effects of infra-red projections into your eyes.

    I made a similar video using a Nintendo 3DS camera showing how the dots look coming out of my Xbox Kinect. https://www.youtube.com/watch?v=emsbWIgRQZo

    Yeah just like Wifi and cellular signals!

    it’s light… LIGHT !!!

    You tubers are friggin idiots. I can’t stand most YouTube videos. The annoying music. The stupidity. The blurry cameras. The annoying accents. The idiotic “what’s up guys” phrase, the environmental waste of destroying devices for clickbait. The fake thumbnail images used as clickbait. Circling something in red with a red arrow in the thumbnail image to lure clicks. The 1000+ top ten videos that all show the same thing, making top ten videos repetitive and useless to watch. Wow it goes on and on. YouTube is the toilet of the internet.

    It’s (laser) light… (laser) LIGHT !!!

    New technology and likely no issue but I wonder the same as My 1/2 cents.

  • toysandme

    It’s not light because it is not visible. It is RADIATION. This is high school physics.

  • TheCyberKnight

    None. The infrared you receive from the sun or your cooktop heating elements is more powerful.
