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.
