A Method to Improve Privacy by Face Recognition and Eye Tracking

More and more people use computers and mobile devices in public areas, and there is a need to protect privacy when a person uses a computer or mobile device when other people may be able to see the screen. Existing methods include using a privacy screen protector which limits the viewing angles. However, it is almost useless if you are in a public area, e.g., working at airport or on a plane because there are almost always people behind you.

    Other prior art uses an image capturing unit to capture an image of an object situated in front of the display, detecting the number of human faces on the captured image, and activating the privacy filter on the display if more than one face is detected on the captured image. However, it does not work at public or crowded spaces because other "faces" are always detected.

    The proposed invention processes the picture/video taking from the camera of the computer or mobile device, and then it identifies faces which are not authorized. For each face, identify eye location, and calculate the confidence level of the eyes that are watching the screen. If the confidence level is high, and/or duration is longer than a pre-set value, then trigger actions to control privacy. Possible action includes:
(1) Black out the screen
(2) Warning to the user
(3) Hide/minimize some programs, etc...

Main features of this invention include:
(1) A method to prevent unauthorized people to re...
