Google Gets Multi Users Face-To-Unlock Willing to Use with Android

Recently Google has managed to acquire a more impressive feature of multi users face-to-unlock feature. You might already have known about face-to-unlock but this time it is multi face-to-unlock which is quite different from the previous feature. With multi face-to-unlock, more users can access to their own personal file with the same device which means that when one sits in front of the built-in camera, the device will be unlocked and automatically retrieve the specific data of user. The data will change if another person sits use face-to-unlock.
