Let’s first startup answering the question “What is this Face ID?”.

The replacement of Touch ID with Face ID in iPhone X

The new iPhone X features Face ID which replaces the traditional Touch ID system. In the recent Apple event, it was made sure that it facial recognition system captures more data points as compared to the Touch ID system which technically makes it more secure.

The testing phase involved augmented eye-scanning system in which the Apple iPhone X Face ID system could unlock your face within 100 milliseconds. Moreover, you need not hold iPhone X directly to your face as the Face ID works while laying flat on a table.

In simple words, it is a facial recognition system. It scans your face at various angles by projecting around invisible dots on your face and creates a facial map. This facial map is encrypted and protected using a Secure Enclave. So, when you need to unlock your device or make any authentication, it is directly made instantly on the device, rather than the cloud. The FaceID recognition system is also working when you are not in light, and while charging it with AirPower wireless charger, and when you are having optics etc.

The unlocking mechanism on the latest Apple devices iPhone X or the upcoming releases is built using Face ID mechanism, which makes your unlocking mechanism and authentication simple and secure.

Just pose your looks in front of the device, irrespective of wearing glasses, wearing a head mask etc, your device automatically recognizes you with its beautiful feature and makes your authentication easier.

FaceID Design Overview

Now, let us see how Face ID was designed on Apple devices. The TrueDepth camera system which was available on latest Apple iPhone (iPhone X), is composed of many innovative technologies.With real-time mechanisms, Apple has used a detailed depth map to recognize your face in a single and short instant.

iPhone X Dot projector and infrared camera

With the Dot Projector, it projects more than 30,000 invisible dots on your face to build up a unique facial map. This facial map helps to recognize an individual’s face uniquely when exposed in front of the camera.

Technology behind FaceID

An infrared camera which was built on iPhone X reads the facial map dot pattern and captures an infrared image. By using this image it sends data to the Secure Enclave. This Secure Enclave was built on the A11 Bionic chip and it helps to confirm the facial match. This beautiful feature initiated with the help of iOS11 update.

The Secure Enclave which was built on the A11 Bionic chip was designed in such a way that it uniquely identifies your face amongst many other faces. The Dot Projector which reads and stores the facial map in the Secure Enclave is capable of recognizing your face even though you wear glasses or a head mask etc..

And, the interesting feature regarding Face ID on iPhone X, is Flood Illuminator. With the Flood Illuminator, it sends invisible infrared light rays which help to identify your face even in darkness. This feature is quite interesting and seems to be most useful right? Because during the night, if there is no electrical power, in such cases it helps the most to make the authentication without any delay.

Apple FaceID is Better than Samsung Galaxy S8 Iris Scan

Apple iPhone X’s Face ID works better than Samsung Galaxy S8 Iris Scan. You can always count on the internet showing several articles and videos on how you can actually unlock galaxy S8 using a two-dimensional photograph. But, Apple features 3D depth sensing camera that eliminates this security concern as well.

Features and Advantages of iPhone X Face ID

Now, coming to the features and advantages of Face ID, it helps to secure your device with the facial recognition system. You can only unlock your iPhone X when you look at it. You need to look at your device with your eyes open to make the device recognize you. With the encrypted facial map which is protected by the Secure Enclave helps to recognize you being resistant to some illegal ways of providing your authenticity like spoofing by masks or photos.

A11 Bionic advanced smartphone chip

The authentication is made instantly on the device rather than the cloud with the A11 Bionic chip built on iPhone X. Irrespective of you are wearing a hat or having a beard or putting on glasses, the device can recognize even if you are near ones couldn’t. For your information, Apple TV 4K is not having the A11 chip, but it is built with an A10X processor.

You can make the payment mechanisms and unlock your devices in an easy and secure way to the Face ID. The most feasible advantage is that you can even unlock your device in dark. The device is sensible in such a way that it makes the screen lit when you seem to be reading something, you can even a lower volume of a ringer or alarm and the Face ID can even reveal messages and notifications on your iPhone X just with your looks.
