Apple has played a key role in popularizing facial recognition, prompting many smartphone manufacturers to follow its lead and integrate this technology into their devices. This innovation has introduced a new dimension to biometric authentication. With the rise of full-screen designs, debates over how smartphones should be unlocked have intensified. While some manufacturers speculated about Apple's upcoming device, the release of the iPhone X created even more uncertainty by introducing Face ID as its primary biometric method. This marked the beginning of a competition between Face ID and fingerprint recognition.
Face ID is not just another form of screen-based identification; it's a sophisticated 3D imaging system that uses active light illumination and specialized cameras to create a detailed 3D model of a user’s face. This model is stored securely on the device and compared during each unlock attempt. The accuracy of Face ID is significantly higher than traditional 2D facial recognition, with a false match probability of 1 in 1,000,000—far better than Touch ID’s 1 in 50,000.
Currently, Apple is the only company offering 3D facial recognition globally. Analysts predict that all future iPhones will adopt this technology, and recent supplier updates suggest this shift is already underway. For instance, Finisar, a major supplier of laser components for Apple, recently acquired a new facility to boost production of 3D sensing modules. This expansion aligns with Apple's expected increase in demand for these parts next year.
While Apple continues to invest heavily in facial recognition, many Android manufacturers are also working on under-display fingerprint technology. Companies like FPC, Synaptics, and Qualcomm are developing ultrasonic and optical solutions, aiming to bring seamless, full-screen unlocking to market. Some of these technologies are already being tested or planned for mass production in 2018.
Despite these efforts, Apple remains ahead in facial recognition, and industry insiders believe it is unlikely to switch to under-screen fingerprints soon. Challenges such as full-screen design limitations and immature screen-fingerprint technology make it a less attractive option for Apple at this time.
In the short term, face recognition will continue to dominate Apple’s strategy, while under-screen fingerprinting remains a backup plan. For Android manufacturers, the race to implement under-screen fingerprinting is heating up, with several companies making significant progress. However, widespread adoption is still a few years away.
Ultimately, both technologies have their strengths, and the future of smartphone authentication may involve a combination of both. Whether Apple will eventually adopt under-screen fingerprinting or stick with Face ID remains to be seen, but one thing is clear: the battle between facial recognition and screen-based biometrics is far from over.
