All you need to know about Apple’s Face ID

Apple’s Face ID Setting

On November 3rd 2017 the much-anticipated Apple’s iPhone X finally hits the market. Unlike other products from Apple, the newly launched iPhone X comes with a more advanced security system called ‘Face ID’.  Like the Fingerprint security authentication that comes with older version of Apples iPhone products, Face ID is used for the verification and authentication of users true Identity.

Apple’s face ID uses similar biometric technology used in Touch ID. One of the major differences here is that Face ID tries to authenticate your identity by scanning through your face and retina. Face ID technology uses your device’s TrueDepth selfie camera to scan through your entire face and it compares the newly taken picture with the previous picture which was initially captured while setting up your Face ID. If there is a match, your device gets automatically unlocked.

How does this technology work?

Now let’s get a bit technical, here is how face ID technology works. Anytime you raise or tap the screen of your device, your device TrueDepth camera is automatically activated for a scan of your face. After the scan, a 2D infrared image of your face will be formed by the camera through its 300,000 plus infrared dots projected by the camera to your face.

Afterwards, a sequence of digitally signed 2D depths and images captured by the TrueDepth camera will subsequently be sent to your iPhones X secured enclave memory chip called the Bionic chip. The data stored in the Bionic chip is then transformed into mathematical representations by your device. These mathematical representations are then compared with your stored facial data which were initially saved data while setting your iPhone X Face ID. If there is a match, your device automatically unlocks otherwise it remains locked.
