How Does Face ID Work on iPhone

Face ID feature on iPhone X makes use of a dot projector, flood illuminator, infrared camera and the A11 Bionic chip to map and recognize your face.

As you look into the front facing camera of iPhone X, a Dot Projector maps the structure of your Face by projecting over 30,000 invisible dots onto your face.

In case of low light conditions, the flood illuminator comes into play, illuminating your face with infrared light.

The dot map is then read by an infrared camera, which conveys the information to a Bionic Chip located on iPhone, which then compares the information about your facial structure with the Facial scan stored on iPhone during the setup process.Face ID Feature in iPhone X

Also, there is an adaptive feature in Face ID that allows it to continue recognizing your face as it changes due to hair style changes or you decide to grow a beard, wear a cap, wear a scarf or undergo cosmetic alterations on your face.

Is Face ID Secure?

According to Apple, the entire process of Facial Mapping and recognition happens right on your device and no information is conveyed to Apple Servers.

Even the adaptive technology that allows iPhone X to continue recognizing your changing face resides right on your iPhone and Apple servers never come into play at any stage.

Also, your facial information is stored in the form a mathematical model on your iPhone and there is no way to re-engineer or reverse the model, in case someone wants to recreate your face.

According to Apple, Face ID is much more secure than Touch ID. The chances of someone unlocking your iPhone X using his/her face are 1 in 1 million, compared to 1 in 50,000 chances of someone being able to unlock your iPhone using Touch ID.
