Nobody likes to have someone looking at the screen of their iPhone while using it, and less if it is a stranger. Every day it happens that sometimes someone around us ends up looking at the screen of our deviceSometimes it is inadvertently, due to inertia or because they have just looked around, but at others it is done with full awareness and deliberation. This is what a recent patent from Apple is about that although for the moment it is just that, if it becomes a reality it will be a serious improvement in the privacy of the use of our iPhone on a daily basis.
A screen only visible to the device owner
The idea is quite simple in terms of operation but with great technology such as Face ID behind. In use, what will happen is that while the iPhone detects a registered face by looking at the screen, it will act normally, but when it detects a second unregistered face by looking at it, the encryption will be activated, according to the patent make the entire area of the screen unreadable that is not where the user was looking at the time.
