A computer-implemented method may include (1) generating or receiving, at a computing device, display data defining a display layout and one or more fields; (2) providing, on a display screen of the computing device and by processing the display data, a display that initially obscures an item of information in a secure field without obscuring an entirety of the display; (3) detecting, using at least a camera of the computing device, a change in orientation of a user relative to the computing device; and (4) in response to the change in orientation, causing the display to show the item of information in the secure field, and after causing the display to show the item, (i) detecting an expiration of a predetermined time limit, and (ii) in response to detecting the expiration, causing the display to again obscure the item in the secure field without obscuring the entirety of the display.
