Abstract:
Apparatuses, methods, systems, and program products securely present content on a display. An apparatus includes a processor and a memory that stores code executable by the processor. The code is executable by the processor to logically divide content to be presented on a display into a plurality of portions and randomly determine security display settings for each of the plurality of portions such that the plurality of portions are presented on the display with their respective security display settings at a frequency above a threshold of human persistence of vision but below camera shutter speeds. The code is executable by the processor to encode the randomly determined security display settings in metadata for each of the plurality of portions prior to the content being presented on the display and send the content, including the encoded security display settings, to the display.
