iPhone X has a system Face ID which uses artificial intelligence to do facial recognition for users around the world, and this may suggest that he could be tricked. Two twin brothers managed to teach Face ID to recognize both of them by "training" the facial recognition system in such a way that different people are recognized by the iPhone X and the unlocking is done.
iPhone X initially refuses to recognize the brother who does not have his face registered in Face ID, but after several unsuccessful attempts, the system learned to recognize his face to give him access to the phone. Everything is based on the artificial intelligence used by the Apple company for Face ID in the iPhone X, it wrongly learning to recognize different faces, and thus a brother can have access to Apple's phone.
iPhone X has been trained to recognize an unknown face by keeping the front camera pointed at the person when facial recognition fails and the security code is entered. The theory formulated in this case is based on the fact that when the security code of the iPhone X is entered, Face ID should know that it is actually the user's face and that it recognized it wrongly.
iPhone X – Face ID can learn several faces, under some conditions
iPhone X needed 3 unsuccessful attempts to be unlocked for Face ID to be able to recognize the face of the second brother, so we are not talking about a completely secure system. Tests for different people do not exist for now, but we will definitely find out if Face ID in the iPhone X can be "trained" to recognize faces of different people, not of brothers who look alike.
iPhone X was presented by the Apple company with the possibility that Face ID could be tricked by a twin brother, and this is possible even without training the system. Well, when the system initially refuses to work, there are methods to make it recognize the face of the twin, so that the iPhone X will give it access to the operating system and the functions it offers for us.
iPhone X has Face ID offered by Apple in an initial version for now, so the system still has a lot to learn before offering high security, even against twins. Until then, it is good to know that if you have a twin, there is a possibility that Face ID in iPhone X will be "taught" to recognize him when he uses your phone.
