The facial recognition feature allows users to unlock their phones by simply looking at them instead of entering a PIN or password, which has been the norm since cell phones came into existence. So, how does your iPhone’s facial recognition feature actually work? Let’s take a look!
Face ID is a facial recognition system designed and developed by Apple, Inc. for the iPhone and iPad Pro. This technology uses the face of the user to unlock and authenticate devices.
Apple announced Face ID during the unveiling of the iPhone X on September 12, 2017. The technology was advertised as Apple’s replacement for Touch ID, a fingerprint-based authentication system built into the home button of the iPhone 8, as well as prior models including the second and third-generation iPhone SE.
Facial recognition works by scanning the user’s face to create a 3D map of their face. From there, the phone identifies key points on the face, such as where the eyes are positioned, and uses that information to calculate a mathematical representation of the person’s face.
Face ID uses strong mathematical algorithms and sophisticated signal processing to ensure that you’re looking at your phone when it unlocks. Face ID is the most secure biometric authentication method available on the iPhone, and Apple made it even more secure with their proprietary Secure Enclave hardware.
