Face ID on iPhone X: What do iOS App Developers Need to Nnow?

By | January 25, 2018

Apple announced a new and expensive version of its popular smartphone, the iPhone X, in September. Subsequently, the company has made the iPhone X available in more than 55 countries and territories. In addition to presenting an edge-to-edge OLED screen, the iPhone X also comes with a range of ready-to-use features to challenge the dominance of the Android platform.

At the same time, the special iPhone model also comes with an exclusive face recognition system: Face ID. Face ID allows users to use their face and conventional passwords. The face scanning system allows the user to unlock his iPhone X by simply looking at the smartphone with open eyes. You can even use Face ID to keep the data stored on your iPhone X safe and make mobile payments.
However, Face ID on iPhone X uses another robust hardware feature on the smartphone: the TrueDepth camera. Many analysts believe that Apple will soon make the innovative face scanning system available for other iPhone and iPad models. Therefore, iOS developers need to understand important aspects of Face ID in iPhone X to meet the emerging trend of mobile app development.

Important aspects of Face ID on iPhone X need to know every developer of iOS apps
Replace Touch ID on iPhone X
Touch ID was an integral part of various iPhone models. With the authentication system, users can unlock their smartphones simply by placing their fingers on the sensor. A user can even use Touch ID to perform various financial transactions and mobile payments. IPhone X is designed with Face ID instead of Touch ID. Unlike Touch ID, users with Face ID do not have to touch their smartphone. A user can take advantage of Face ID to unlock their device simply by looking at the screen. At the same time, developers of the iOS application can benefit from the new facial recognition system simply by replacing the Touch ID code with the Face ID code.
It does not make the keys unnecessary
Despite the fact that Touch ID has been replaced in iPhone X, Face ID still has to completely replace the access codes. Apple recommends that iPhone X users use passwords when they restart the device, the device remains unlocked for more than 48 hours, and the user has tried to get the wrong face five times. In addition, a user must use an access code to make his iPhone X accessible to friends and family.

It is verified via the TrueDepth camera
Face ID verifies users via another new feature of the iPhone X: TrueDepth camera system. The advanced camera system captures all functions of a user’s face via depth assignment. In addition, TrueDepth creates a unique face card by capturing over 30000 invisible points projected onto a user’s face. Every time a user unlocks his iPhone X, the TrueDepth camera reads the dot patterns via an infrared camera and captures an infrared image. Then send the infrared image to Secure Enclave on the Bionic A11 chip. Once the authenticity of the infrared image is confirmed, the iPhone is unlocked.

Used machine learning
The appearance of a user may vary from time to time. Face ID uses algorithms for learning the machine to recognize changes in a user’s appearance. That’s why a user can unlock his iPhone X regardless of their current appearance. You can use Face ID on iPhone X to unlock and verify, despite wearing a hat, setting up glasses and growing your beard. The TrueDepth camera also uses a spotlight to identify the user’s face through invisible infrared light when there is insufficient light.

 

Prevents unauthorized access to devices
Although different appearances of the same user have been identified, Face ID on iPhone X still does not allow other people to unlock the smartphone. When unlocking the iPhone X, the user must keep their eyes open. When the user’s eyes are closed, the iPhone X remains unlocked. The feature makes it difficult for unauthorized users to unlock the mobile device when the original user is asleep or absent. However, Face ID on iPhone X does not allow identifying identical twins. A user must also use an access code to prevent their iPhone X from being inaccessible to twins.

There is no option to register multiple users
Apple further improves the security of iPhone X by making each user record a single face. No user has the option to register multiple faces. Therefore, only one user can unlock and verify through the face ID. However, a user can make his iPhone X accessible to multiple users by sharing his password. Multiple users can access the same iPhone X by authenticating through an access code instead of Face ID.

Perform multiple tasks
Face ID not only improves the iPhone X, but also improves the user experience by performing a series of basic tasks. The conscious nature of facial recognition system attention allows users to perform simple tasks by simply looking at the iPhone X. For example, a user can use Face ID to check messages and notifications, reduce the volume of the alarm or ring tone, and keep the screen on while you read.

Facilitate mobile payments

Along with the improved security of iPhone X, Face ID facilitates mobile payments. It will work without problems with Apple Pay. A user can also use Face ID on iPhone X while shopping at physical stores and restaurants that support Touch ID payments. Touch ID compatible applications can also allow users to benefit from Face ID. Developers can support their existing Face iOS ID Face by replacing the Touch ID code with the Face ID code. However, many banks and financial institutions do not yet have to fully admit Face ID.

Security and privacy issues
Apple implements several security mechanisms to keep face scanning private and secure. After scanning a user’s face, the TrueDepth Camera system saved the information directly on the Bionic A11 chip. Apple does not transfer the information to your server or cloud. That is why the information to scan the face remains on the iPhone X. Apple continues to use the facial recognition system as a robust security tool to keep user data inaccessible and prevent unauthorized access. A hacker in Vietnam recently claimed that he should break Face ID by creating a complex mask. But several security experts believe that Apple needs to make some changes to Face ID in iPhone X to make it an effective security measure.

In general, Face ID on iPhone X transforms the development of iOS applications by replacing Touch ID. But the developers of the iOS app should remember that the face recognition system is currently only used by a single iPhone model. Apple will gradually make Face ID available for the next iPhone and iPad versions. That’s why developers need to explore ways to support their existing iOS Face ID applications. In addition, they must adopt emerging trends in the development of iOS applications to make their mobile application relevant and popular for a longer period.
