Apple announced a new and expensive edition of its popular smartphone – iPhone X – in September. The company subsequently made iPhone X available in more than 55 countries and territories. In addition to featuring an edge-to-edge OLED display, iPhone X also comes with a number of out-of-box features to challenge the dominance of Android platform.
At the same time, the special iPhone model also comes with an exclusive facial recognition system – Face ID. Face ID enables users to use their face just like conventional passwords. The facial scanning system enables a user to unlock his iPhone X simply by looking towards the smartphone with his eyes open. He can even use Face ID to keep the data stored on his iPhone X secure and make mobile payments.
However, Face ID in iPhone X takes advantage of another robust hardware feature included in the smartphone – TrueDepth camera. Many analysts believe that Apple will soon make the innovative facial scanning system available to other iPhone and iPad models. Hence, the iOS developers must understand important aspects of Face ID in iPhone X to meet the emerging mobile app development trend.
Important Aspects of Face ID in iPhone X each iOS App Developer Must Know
Replaces Touch ID on iPhone X
Touch ID was an integral part of several iPhone models. The authentication system enables users to unlock their smartphones simply by placing their fingers on the sensor. A user can even 回收手機 use Touch ID to perform various financial transactions and mobile payment. IPhone X is designed with Face ID instead of Touch ID. Unlike Touch ID, Face ID does not require users to touch their smartphones. A user can take advantage of Face ID to unlock his device simply by glancing at the screen. At the same time, the iOS app developers can take advantage of the new facial recognition system simply by replacing the Touch ID code with Face ID code.
Does not make Passcodes Obsolete
Despite replacing Touch ID on iPhone X, Face ID is yet to replace passcodes fully. Apple recommends iPhone X users to use passcodes while restarting the device, the device has remained unlocked for more than 48 hours, and the user has attempted wrong face match five times. Also, a user has to use passcode to make his iPhone X accessible to friends and family members.
Authenticates through TrueDepth Camera
Face ID authenticates users through another new feature provided by iPhone X – TrueDepth camera system. The advanced camera system captures all features of a user’s face through depth mapping. Also, TrueDepth creates a unique facial map by capturing over 30000 invisible dots projected onto a user’s face. Each time a user unlocks his iPhone X, TrueDepth Camera reads the dot patterns through an infrared camera and captures an infrared image. It subsequently sends the infrared image to Secure Enclave in the A11 Bionic chip. Once authenticity of the infrared image is confirmed the iPhone gets unlocked.
Uses Machine Learning
A user’s appearance may differ from time to time. Face ID uses machine learning algorithms to recognize the changes in a user’s appearance. Hence, a user can unlock his iPhone X regardless of his current appearance. He can take advantage of Face ID in iPhone X to unlock and authenticate despite wearing a hat, putting on glasses, and growing a beard. TrueDepth Camera further uses a flood illuminator to identify a user’s face through invisible infrared light when there is inadequate light.
