Abstract: A pseudo-random steganographic camouflage includes a graphic design printed or painted as camouflage on an outer side of a substrate like Mylar thermal blanket sheets, uniforms, and adhesive tapes. The graphic design is uniquely generated from pseudo-random noise in four overlaying colors that each begin as a raster of randomly generated noise CDMA encoded with a PRN and a message in a standardized tile size. E.g., gray, green, tan, and brown colors natural for concealment applications are each masked by two-tone image contrast rasters. The four results are mixed in groups together with a monochrome mixing mask to produce a whole tile of concealment camouflage that will conjoin seamlessly within arrays of such tiles. A further refinement visually adds a distorted-grid mesh-texture to the pseudo-random steganographic camouflage, and even faint “watermarks” of commercial trademarks.
