Apple has announced a new way for biometric login called Face ID which will be seen on the iPhone X. But if it catches on in popularity, KGI Securities claims that this feature may be available on all iPhones from next year onwards.
According to a report by the 9to5 Mac, KGI securities have predicted that if the Face ID technology becomes popular among the people, Apple may do away with the Touch ID. It may add the TrueDepth camera module on all its future smartphones.
Until now, Touch ID has been the point of security for most of the iPhones, which relies on fingerprint scanning.
According to KGI, even if the Face ID fails to impress the people, Apple may bring the under-display Touch ID.
However, Face ID has received its own flak. Its release has brought security concerns to the forefront, especially ones pertaining to privacy.
Apple’s SVP of Software Engineering, Craig Federighi, in an interview with TechCrunch had said, “We do not gather customer data when you enroll in Face ID, it stays on your device, we do not send it to the cloud for training data.”
Face ID feature is activated using the TrueDepth camera module, which has in order from left to right, an IR camera, an IR emitter that Apple calls a ‘Flood Illuminator’, a structured light emitter aka ‘Dot projector’ and the front-facing camera.
The Flood illuminator is basically an invisible torch light that shines on your face, illuminating it in a light spectrum that only an IR camera can see. The Dot projector paints your face with something like tiny lasers. These “dots”, 30,000 of which are projected on your face, are picked up by the IR camera and the data is used to create a 3D depth map of your face. All this processing happens aboard the A11 Bionic chip and never leaves the phone. The generated depth map is then compared to the original depth map of your face to authenticate.
