A system for verifying the integrity, continuity, and availability of information displayed on an uncertified display, the system comprising: a server that is certified to generate mission critical data for display; an adapter device configured to house an uncertified display device that provides the uncertified display; and a screen capture system configured to capture an image displayed on the uncertified display; wherein the system is configured to: create, on the server, application data for display on the uncertified display device that includes a subliminal symbol that is periodically embedded in a few out of multiple tens of frames (802, 806) and that is camouflaged in the application data using steganography; transmit the application data to the uncertified display device for display; capture, using the screen capture system, images of the application data displayed on the display screen of the uncertified display device that includes the subliminal symbol that is camouflaged using steganography; transmit the captured images to the server; determine, at the server, whether the subliminal symbol is detected in the captured images of the application data by extracting, at the server, the symbol from the captured images and comparing the extracted symbol to an expected symbol; determine that the application data is not corrupted when the extracted symbol matches the expected symbol; identify a loss of ICA when the subliminal symbol is not detected in the application data displayed on the uncertified display device or does not match the expected symbol; and transmit an error indicator, from the server to the adapter device, when a loss of ICA is identified, characterized in that the subliminal symbol is camouflaged in the application data using two-frame contrasting color steganography for non-greyscale colors. a server that is certified to generate mission critical data for display; an adapter device configured to house an uncertified display device that provides the uncertified display; and a screen capture system configured to capture an image displayed on the uncertified display; wherein the system is configured to: create, on the server, application data for display on the uncertified display device that includes a subliminal symbol that is periodically embedded in a few out of multiple tens of frames (802, 806) and that is camouflaged in the application data using steganography; transmit the application data to the uncertified display device for display; capture, using the screen capture system, images of the application data displayed on the display screen of the uncertified display device that includes the subliminal symbol that is camouflaged using steganography; transmit the captured images to the server; determine, at the server, whether the subliminal symbol is detected in the captured images of the application data by extracting, at the server, the symbol from the captured images and comparing the extracted symbol to an expected symbol; determine that the application data is not corrupted when the extracted symbol matches the expected symbol; identify a loss of ICA when the subliminal symbol is not detected in the application data displayed on the uncertified display device or does not match the expected symbol; and transmit an error indicator, from the server to the adapter device, when a loss of ICA is identified, characterized in that the subliminal symbol is camouflaged in the application data using two-frame contrasting color steganography for non-greyscale colors. create, on the server, application data for display on the uncertified display device that includes a subliminal symbol that is periodically embedded in a few out of multiple tens of frames (802, 806) and that is camouflaged in the application data using steganography; transmit the application data to the uncertified display device for display; capture, using the screen capture system, images of the application data displayed on the display screen of the uncertified display device that includes the subliminal symbol that is camouflaged using steganography; transmit the captured images to the server; determine, at the server, whether the subliminal symbol is detected in the captured images of the application data by extracting, at the server, the symbol from the captured images and comparing the extracted symbol to an expected symbol; determine that the application data is not corrupted when the extracted symbol matches the expected symbol; identify a loss of ICA when the subliminal symbol is not detected in the application data displayed on the uncertified display device or does not match the expected symbol; and transmit an error indicator, from the server to the adapter device, when a loss of ICA is identified, characterized in that the subliminal symbol is camouflaged in the application data using two-frame contrasting color steganography for non-greyscale colors.
