PROTECTING DISPLAY OF POTENTIALLY SENSITIVE INFORMATION

摘要

The security and privacy of a user is enhanced by distinguishing between potentially sensitive information and non-sensitive information being displayed on a display of a computing device. In an embodiment, potentially sensitive information on a display is identified by parsing information to be displayed. A front-facing camera of the user's computing device is used to monitor the user's background and compare any changes to a threshold amount. In response to a detected change in the background, actions are taken to alert the user or reduce the visibility of identified potentially sensitive information shown on the display screen.

主权项

1. A method comprising:
accessing, by a computing device, information that is to be displayed on a display of the computing device, the accessed information including both potentially sensitive information and non-sensitive information; parsing the accessed information, by the computing device, to identify the potentially sensitive information and the non-sensitive information; obtaining a first image of an area from a front-facing camera of the computing device, the first image having a foreground and a background; receiving a second image of the area from the front-facing camera, the second image having a foreground and a background; comparing by the computing device the background of the second image with the background of the first image to identify a change in the background in the second image; and determining whether the change exceeds a predetermined threshold amount; displaying, by the computing device, the accessed information on the display; and when the change exceeds the predetermined threshold amount, obscuring, by the computing device, regions of the display where the identified potentially sensitive information is displayed.
