METHOD FOR PREVENTING INFORMATION DISPLAYED ON SCREEN FROM BEING VIEWED WITHOUT AUTHORIZATION AND DISPLAY DEVICE HAVING ANTI-VIEWING FUNCTION

摘要

A computerized method prevents information displayed on a screen of a display device from being viewed by unauthorized persons. Images in front of the screen are captured at regular intervals using an image capturing device of the display device. Faces are recognized from each of the captured images using facial recognition technologies. Whether or not the screen is in a state of being viewed by one or more unauthorized persons is determined according to the faces recognized as such in each of the captured images. A predetermined anti-viewing display is displayed on the screen to prevent the information being displayed on the screen from being viewed by any unauthorized person, when the screen is determined to be in the state of being viewed by any unauthorized person.
