Abstract: A method for verifying the integrity, continuity, and availability (ICA) of information displayed on an uncertified display is disclosed. The method includes creating 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 and that is camouflaged in the application data using steganography; transmitting the application data to the uncertified display device for display; receiving images of the application data displayed on the display screen; determining whether the subliminal symbol is detected in the captured images by extracting the symbol from the captured images and comparing the extracted symbol to an expected symbol; determining that the application data is not corrupted when the extracted symbol matches the expected symbol; and identifying a loss of ICA when the subliminal symbol is not detected or does not match the expected symbol.

Abstract: A method executable by an ownship aircraft for probabilistically determining an intended flight route of an other aircraft in the vicinity of the ownship aircraft includes receiving first positional information regarding the other aircraft at a first point in time, receiving second positional information regarding the other aircraft at a second point in time that is temporally subsequent to the first point in time, and determining a historical flight path of the other aircraft based on the first and second positional information. Furthermore, the method includes comparing the historical flight path of the other aircraft to a plurality of navigation routes and, based on the comparing, probabilistically determining one navigation route of the plurality of navigation routes as the intended flight route of the other aircraft.
