US 11,090,966 B2 · Method for manufacturing pseudo-random steganographic camouflage

Abstract

A concealment substrate manufacturing process begins by printing or painting a graphic design as camouflage on substrates like mesh-textured uniforms, military equipment, Mylar thermal blanket sheets, adhesive tapes, etc. The graphic design is uniquely generated from pseudo-random noise in four overlaying color pigments that each begin as a raster of randomly generated noise 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 together in groups with a monochrome mixing mask to produce a whole tile. Such concealment camouflage tile conjoins seamlessly on-edge within other arrays of identical tiles. One variation adds a distorted-grid mesh-texture overly texture to the concealment camouflage, and even a faint “watermark” related to a commercial trademark.

Dependent claims

A manufacturing method that produces a pseudo-random steganographic camouflage on a substrate, the manufacturing method comprising:

setting a printable and displayable message;
setting a fill pattern to visibly surround the message when printed or displayed;
predetermining a pseudo-random number (PRN) set for encoding a code in a code-division multiple access (CDMA) modulator;
employing a CDMA modulator to CDMA-modulate a digital serialization of the message and the fill pattern with the PRN into component colors, saturations, and light levels that fit a particular camouflage theme;
converting a serialization of the message and the fill pattern with the PRN with a two-dimensional raster generator into a raster of horizontal scanning lines for color printing;
and
applying byway of a color printer an application of color pigments to a substrate according to the serialization of the message and the fill pattern with the PRN into component colors, saturations, and light levels;
wherein, a pseudo-random steganographic camouflage thereby produced on the substrate visually displays the message which is discernable to only cameras equipped with a CDMA demodulator and the PRN.
