What does it mean that the mobile phone has no face?

That is, whether it has the face unlocking function. Face unlocking can use the front camera of the device to scan and detect the features of the user's face. Specifically, it refers to the technology that allows the user to completely obtain the personal information stored in the device by recognizing the face. This technology has been applied to information security fields such as computers and mobile phones.

Apple's technology is more than just using facial recognition to unlock users' devices. When the user is confirmed by the system, the system can start various targeted applications according to the preset settings. According to the patent, "if the user is successfully identified, then all operations will be run on this basis, and the user can modify the predefined open mail and information." .

Now facial unlocking software can be widely used on Android platform. As long as your laptop has a front camera, you can easily and quickly add a security software to protect your laptop.
