The Face ID feature on iPhone X stands out as the most prominent and remarkable feature on this mobile phone. So, how does this feature operate? Let's delve into it with Mytour Superstore in the following article.
Unlocking speed faster than Touch ID

On the iPhone X, Apple introduces the facial recognition feature known as Face ID. Face ID serves as the biometric security feature replacing Touch ID (fingerprint security) on the iPhone X. This sensor relies on building a 3D model of the face. Then, the device compares it with the stored model to unlock. Users simply need to raise the iPhone X, iPhone 14 Plus 512GB,..., glance at the device to unlock, with very fast speed.
Face recognition accuracy between real and fake faces reaches up to 1 million times
The facial recognition technology (Face ID) of the iPhone X derives its power from the neural networks, known as the A11 Bionic neural engine. This engine is essentially a processing system. It has a 2-core design and the capability to process 600 billion operations per second.

During the processing, users need to focus in order to unlock. Face ID can even recognize someone's face while they're wearing a hat, sporting a beard, and in low-light conditions. Of course, this system won't be fooled by images, even if they're 3D-printed masks.
Facial data is protected by a secure enclave on the chip. If Touch ID (fingerprint sensor) has a 1 in 50,000 chance of someone stealing data to access your phone, with Face ID, that chance is only 1 in 1 million. It seems almost impossible.

When you look at the screen of the iPhone X, the face recognition system will be activated, sensors located in the black bezel of the iPhone X will start working. Apple calls this sensor system the TrueDepth Camera System. It operates in the following sequence:
1. The flood illuminator initiates the workflow by emitting a non-visible light beam, meaning it's not visible to the human eye. This beam has the task of 'illuminating' your face both in bright and low-light conditions.
2. The infrared sensor then projects infrared rays to capture the shape of the face. The light stream is also non-visible light to the human eye.
3. Dot projector, a rare component on smartphones, continues to emit a series of small infrared dots onto the user's face. About 30,000 dots like these are emitted each time Face ID is active, and the infrared sensor also has the task of recording these dots.
4. Images from the infrared sensor + images of the dots emitted by the dot projector are sent to the Apple A11 Bionic processor to run artificial intelligence algorithms. These algorithms will construct a 'model' of the face of the person unlocking the device, checking if it matches the pre-registered facial data.
5. If it matches, the device will unlock and grant you access.

The Face ID system of the iPhone X actually features facial scanning technology aided by the ability to record new facial expressions, facilitating the reading of users' facial expressions and incorporating them into messages and speech.
Additionally, Apple collaborates with Snapchat to filter new faces through AR Kit.
