Abstract
This is directed to obfuscating a display to secure the display of information provided to a user. An electronic device can modulate the display of information using different approaches, including for example by adding artifacts or changing the color, frequency or polarity of displayed information, thus obfuscating the display. To view the displayed information, a user can place a filter between the user and the display (e.g., as part of glasses) such that the filter can remove or undo the obfuscation. In some embodiments, the device can display different confidential information for several users simultaneously, where different obfuscation approaches are used for each user. This can allow several users to interact with the device simultaneously while ensuring that each user's information remains confidential.
