Face ID is an innovative biometric authentication system that Apple developed to provide users with a secure and convenient method of unlocking their iPhone and approving App Store purchases. By leveraging advanced facial scanning technology and Artificial Intelligence (AI), Face ID offers a natural user experience that is both highly secure and effortless.
When setting up Face ID for the first time, users are required to scan their face by moving their head in a circle to capture all angles. The TrueDepth camera projects over 30,000 infrared dots onto the face which allows the phone to map out facial contours with precision. This creates a mathematical model of the face rather than storing an actual picture.
Once configured, Face ID can quickly authenticate users by detecting facial characteristics such as the shape of eyes, nose, lips as well as other patterns. The likelihood of a false match is approximately 1 in 1,000,000 which makes Face ID extremely reliable. Users simply have to look at their device to unlock it or approve App Store purchases and payments.
Face ID works by extracting a rough depth map of a user’s face using the embedded TrueDepth sensor in compatible iPhones and iPads. This creates a sequence of 2D images which are pushed through a neural network to generate a mathematical model based on facial features. The model considers over 30,000 points on the face creating a highly detailed representation.
This modeled facial data is then encrypted and stored in the Secure Enclave, an isolated security chip used to handle sensitive biometric information. During authentication, Face ID compares a fresh image of the user’s face to the stored model to determine if they are a match. This happens on-device for maximum security.
When authenticating with Face ID, only attested model information leaves the Secure Enclave after any mathematical comparisons are made. The images are never accessible by iOS or any apps. Facial representations also aren’t uploaded to Apple’s servers. This ensures privacy is maintained while taking advantage of facial recognition.
Face ID has revolutionised biometric authentication thanks to its speed, accuracy and security over password-only protection. Users no longer have to constantly enter passcodes to unlock their phone and approve purchases. Just a simple glance provides access making it a frictionless experience.
For many users, Face ID has become an indispensable part of the iPhone experience. The ability to secure their device and seamlessly approve App Store downloads using facial biometrics provides convenience without compromising security.
