Face ID is a form of biometric authentication. Instead of a password, security key or Touch-ID for protection (from unwanted viewing of your data), biometrics is your unique identifier (Unique fingerprint or face shot). Fingerprint recognition is also biometric. So how to set up Face ID on iPhone X?

How to set up Face ID correctly on iPhone, setting Face ID?

Face ID uses the “Registration” process, as with Touch ID.

1. First go to “Settings” > “Face ID and Password” and click “Save.”

Then the iPhone will turn on the front camera by displaying your face in a circle with green marks surrounding it. The registration software will overlay 3D markings on the screen to show your eye line and face.

2. You need to turn your head in a circle so that Face ID scans your face.

Is Face ID safe?

Apple says that the probability that someone else’s fingerprint unlocks the iPhone using Touch ID is 1 in 50,000. Apple claims that the chance to unlock iPhone using Face ID is 1 in 1,000,000. But what about your twins?

Apple’s senior vice president of marketing, Phil Schiller, said during a presentation of the iPhone X: “The statistics are lower if a person is close in genetics.” Simply put, the chance to unlock your iPhone is higher if it’s your relative (Brother, sister). Apple clarified this in its white paper, noting that the accuracy is “Miscellaneous” for twins, brothers and sisters. If you have an evil twin, you should probably be careful with Face ID.

They also said that children under 13 years old had a higher rate of false matches, although the company did not name numbers because various facial features were not fully developed. Face ID is not suitable for children under 13 years old, as their faces are constantly changing (Children are actively growing).

Can someone else deceive Face ID, sculpture, 3D model?

The answer should be negative, based on the approach taken by Apple: the number of data points, the use of infrared scanning and the attention function. People tried to trick Face ID using photographs, plaster models, and other methods. But the plaster model does not give the same reflection as a 100 percent identical human face, because infrared radiation reflects living skin differently than with inanimate material.

Apple says in the documentation that it introduces randomness to make it even more complex. The sequence of 2D infrared scans and captures of depth-map points is sent in random order, and the design point-template is random and unique for each device. This makes it more difficult for an attacker to use predictable elements to trick a scanner.

In a white paper with an identification mark of the face, it is noted that although there is a primary neural network that performs identification, second the neural network checks for fake by looking at the indicators of photographs and masks.

How Face ID works, parsed on fingers

Apple uses a combination of infrared emitter and sensor (called TrueDepth) to draw and track 30,000 points of infrared light around your face, and capture flat or 2D infrared images. For points, reflection is measured, which allows you to calculate the depth and angle from the camera for each point and build a depth map.

The information collected for the depth map in Face ID is used by Apple’s new Animoji feature. (You can become a fun cocoa)

What devices does Face ID support?

So far, only iPhone X plans to implement Face ID. It will also be on new phones or even on Apple’s iPad.

Why should I use Face ID?

For purchases on Apple Pay, the App Store and iTunes, as well as third-party apps that currently rely on Touch ID only. Apple claims that third-party applications with Touch IDs will be able to enable authentication with Face ID.

Interestingly, Apple says developers can use Face ID without a password if the developer wants to use biometric identification as a kind of second factor that cannot be circumvented.

Can I set a face ID so that the faces of several people unlock the same iPhone?

Currently, the iPhone X only recognizes one face. This may change in the future. But you can no longer give your spouse, partner or other person access to your phone using biometric means, as you could by registering one of your fingers using Touch ID. You will need to share a password with them.
