Abstract
Embodiments of the invention are directed to systems and methods for protecting content by automatically identifying a display surface viewable only to authorized users and displaying protected content on the identified display surface. In one example embodiment, content is displayed on a first display surface in viewable range of a first user authorized to view the content. The entrance of a second user into viewable range of the first display surface is detected, and automatically determined to be unauthorized to view the content. A second display surface in viewable range of the first user but not viewable by the second user is automatically identified in response to detecting the entrance of the second, unauthorized user into viewable range of the first display surface. The display of the content is automatically moved from the first display surface to the second display surface to prevent the content from being viewed by the unauthorized user.
