For the better part of a year rumors have been swirling about the features and design of Apple's yet-to-be launched iPhone 8.
Of particular note is the potential for an infra-red face unlock in BiometricKit, which will essentially work as a facial authentication on the same framework as Touch ID.
All this new information comes from Apple itself. However, only Apple apps made for the HomePod will run on it initially. The company released the firmware for the device today and it gives some details for it. Like, say, its upcoming iPhone.
At this point, we can not vouch for "Pearl ID" being the official name of the feature yet since there have been speculations that it will be called a more descriptive name like the "Face ID". The firmware also includes reference to "BKFaceDetect" and events such as "TooFarFromCamera" and "MultipleFaces". Those references don't exist in the iOS 11 beta.
This, MacRumors notes, gives the impression that the new phone could rely on facial recognition in some capacity, such as for locking and unlocking the device.
According to the same interview, the intention is for the facial scan to become a feature alongside Touch ID, rather than replacing it.
Because an infrared camera creates a 3D image of a face, it has advantages over face recognition performed with light-dependent cameras. The code, Troughton-Smith argued, is the smoking gun. Other rumors suggest that there will be a more expensive, anniversary edition added to the iPhone lineup, wireless charging, support for the Apple Pencil, and more. "The codename is D22, and there is also a mention of 'iPhone9" that could be related to the upcoming iPhone 7s.
The pair also found a visual icon used to represent D22. Rambo shared the image on Twitter. "If you're not taking that approach now, it's perceived that you're not at the leading edge of design, where Apple wants to be". The face-ID feature seems primed to be a focal point of the company's eventual introduction of the phone.
