Abstract: The proposed technology enables new levels of privacy while using electronics in open or public settings via the modification and censorship of a device's displayed content in response to the presence of spectators within a visible range of content displayed. In an open or public environment, users of electronic devices with any form of display can have their privacy and security compromised by any unauthorized spectators within the aforementioned visible range. To combat this problem, the proposed technology monitors the presence of users and spectators within predetermined regions and changes the content displayed appropriately such that the spectators are deterred or prevented from viewing the user's (or users) content. The system provides an added layer of security which is advantageous to users who prefer to use their devices in public locations but are afraid of being visually hacked.
