The touch ID or other FPS has been around for a while. You think Apple is the only one the spends time and money on this technology. Btw... Authentech was the one who did R&D for biometrics long before Apple thought about using Touch ID on the iPhone. Guess who Authentech was partnered with before Apple purchased them? That's right! That evil company we know of named Samsung. Let me guess, you think Apple did R&D for Face ID as well?
First, you insinuate, a lot. I have no idea why you're even bringing touch ID into this discussion. I'm not referring to Touch ID, it's about other forms of biometric that have been bypassed with facial recognition, as with Samsung. And I don't find Samsung to be an evil Company or even why are you assuming this. However I am implicating the truth that Samsungs facial recognition has been defeated by others with a photo. Apples research and development team is guaranteeing that it cannot be fooled by photo and even went as far as using replica masks of somebody's face to ensure it cannot be bypassed.
Nobody's questioning if Facial technology has not been around for a while, but how many of them are using this as their primary source of security and have not gotten hacked? Apple is claiming they took the insecurities of previous facial recognition and made sure there it cannot be fooled to great lengths. Apple has one primary form of security that are using with iPhone X and that will be Face ID. So you can guarantee the research and development went beyond To ensure the security will not be manipulated and protecting millions of consumers identity.
