Method of screen security with facial recognition

Nowadays, nearly all PC or mobile device have a lock mode. There are some current invention using facial recognition to unlock the device, but after unlocked, it still could be access by an unauthorized person. Moreover, during the time when an authorized person is using the device, there could appear a second unauthorized person looking at the same screen behind the back of an authorized person, this could cause some dangerous situations, e.g., while the authorized person is reading confidential material or inputting a password. Secrets leaking by this way is more dangerous than leaking from network, and the authorized user could hardly noticed. It is quite useful to protect the content on screen when the second unauthorized person is approaching.

The present invention provide a way of prevent unauthorized second person (or more person) from getting information from the authorized person's display device by looking with naked eyes.

To achieve this end, the method is to continuously processing the video come from the camera, because most of current mobile device have a camera point to the user's face, but most of the time when user is not using it for taking photos, they are not in the working mode at all, and it is also a waste. The camera using the facial recognition to continuously confirm that the authorized user is using the device, and it will lock the device or show a completely different picture/view/desktop as soon as it detected the second person's face from the camera, if user feels it is little aggressive to do it as soon as a second unauthorized face is detected, he/she could turn down the sensitivity, e.g., lock the device or show a completely different picture/view/desktop when the other face is near a predefined range of the camera , by doing so, it could largely prevent the possibility of leaking information from unauthorized person's naked eye.

After a device is unlocked, the authorized user start to use the device(the unlock method could be any kind of current existing method), like the flow chat shows:
