1. A method comprising:
receiving, by a dedicated display device, a signal comprising an image to be displayed by the dedicated display device before the image is displayed by the dedicated display device,
wherein the signal is received from a client computing device,
wherein the dedicated display device is external to the client computing device;
converting, by the dedicated display device, the image into a virtual bitmap display;
analyzing, by the dedicated display device, the virtual bitmap display based on a content recognition algorithm to identify an object in the virtual bitmap display;
determining, by the dedicated display device, to redact the object based on a ruleset;
determining that a processing time required to analyze the virtual bitmap display and modify the signal is longer than a refresh rate of the dedicated display device;
looping, based on the determination the processing time required to analyze the virtual bitmap display and modify the signal is longer than the refresh rate of the dedicated display device, an earlier frame on the dedicated display device; and
modifying, by the dedicated display device, the signal to redact the object from the virtual bitmap display responsive to determining to redact the object.
