Editor to share with you what faceid means. I hope you will get something after reading this article. Let's discuss it together.

Faceid refers to face ID, a face recognition system designed and released by Apple for the first time in iPhone X; it allows users to unlock Apple devices, buy them in various Apple digital media stores, and authenticate payments within Apple Pay or apps.

Face ID (English: Face ID) is a face recognition system designed and released by Apple, which is used for the first time in iPhone X. This feature was first announced on September 12, 2017 and is intended to replace touch ID rather than add a new security mechanism. It allows users to unlock Apple devices, buy them in various Apple digital media stores (iTunes Store, App Store and iBooks Store), and authenticate payments within Apple Pay or apps.

Apple says it has a 1/1000000 chance of not unlocking the phone. Apple also said that face recognition information is stored locally in the secure area of the Apple A11 Bionic and next-generation chips and will not be stored in the cloud.

The devices available are:

IPhone (X, X floor, Xs/Max, 11, 11 Pro/Max, 12/Mini, 12 Pro/Pro Max)

IPad Pro (third and fourth generations)

Principle

Face ID will first illuminate the user's face with an omni light sensor module to obtain 2D infrared photos, and then use the infrared camera to identify them. Then, using the lattice projector to cast more than 30,000 specially coded infrared points on the surface of the object, and then reflecting back to the infrared camera receiver, using the offset between the infrared photos and the reflected infrared points, the object can obtain the depth of field information of the face surface. As a result, a 3D accurate model is constructed, and then the infrared image and the 3D accurate model are sent to the processor and converted into a mathematical expression that compares previously registered facial data and draws a conclusion. The function of "gaze unlocking" is achieved through infrared cameras to capture images of the eyeball and recognize pupil features. The technology providers are SensoMotoric Instruments, PrimeSense, which provides structured light technology, and FaceShift, which provides facial capture technology.

Features

Flood illuminator

The use of invisible infrared light to help identify faces, which is still available in dim light, allows the infrared camera to determine whether the eye is looking directly at the screen to ensure that only the user can unlock it. And use artificial intelligence to learn to remember constant changes in appearance.

Lattice projector

More than 30,000 invisible positioning points are shot to the face to construct a unique facial three-dimensional feature. in addition, the arrangement and combination of each light spot on the transmitter is also unique.

infrared camera

The infrared camera is used to capture the plane infrared image and read the three-dimensional lattice graphics at the same time. After the information of the above two neural network analysis is digitized, the data will be sent to the security area in the A11 Bionic chip to confirm the match.
