AC-11(1): Pattern-hiding Displays
The information system conceals, via the session lock, information previously visible on the display with a publicly viewable image.
Supplemental
Publicly viewable images can include static or dynamic images, for example, patterns used with screen savers, photographic images, solid colors, clock, battery life indicator, or a blank screen, with the additional caveat that none of the images convey sensitive information.
