Can the screen scanning software see the face?

This may be a software that peeks at other people's screens. This software may be a Trojan virus software. Its main function is to peek at other people's screens, peek at the dynamics on other people's screens, and may observe some private information of others. Therefore, I think this software may be an illegal software, because it is a software that peeks at other people's personal information.
