Face ID is the next big thing.
Time and time again Apple has come up bold and courageous technologies when it comes to privacy, security, and ease-of-use. It was in 2013, Apple introduced Touch ID that sophisticated users to unlock their phone with just pressing the fingerprint sensor. It was a benchmark then that was incorporated by major smartphone companies only a couple of years later. Almost all the mid- and high-end smartphones released after 2015 had Touch ID built onto them. Nowadays we don’t even have to press the button, placing your finger should do good. Now with the unveiling of iPhone X, Apple has yet again come up with a bold move, Face ID. Unlock your phone by just looking at it.
Let’s see how it works now. iPhone X has a special bunch of hardware they call TrueDepth Camera System to make Face ID work. It comprises of Infrared camera, Flood illuminator, Dot projector, Proximity sensor and Ambient light sensor. These are the hardware required for Face ID to work.
Proximity sensor; detects whenever you’re holding your phone against your face;
Ambient light sensor; detects the ambient light and decides whether are not the Flood illuminator needs to be activated. If the ambient light is bright enough, there won’t be a necessity for illumination.
Flood illuminator; illuminates your face during the dark
Dot projector; projects 30,000 precise dots to create a depth map of your face.
Infrared camera; captures the depth map and sends it to the A11 bionic chip.
It’s designed spoof-proof, that’s what Apple claims. Your facial depth map is stored in a secure enclave. Wearing a headband, cap, sunglasses, or any other sort of accessory shouldn’t be a problem and yet iPhone X will recognize you. This is done using the A11 Bionic chip’s machine learning. Within a short span of time, the machine learns the changes in your appearance and would cope up accordingly. Apple boldly says that "Your friends might not recognize you, but iPhone X will."
