Pseudo-random steganographic camouflage

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.

1 . A pseudo-random steganographic camouflage, comprising:
 a base substrate;   a rectangular shaped tile area disposed in a tiled arrangement on the outer side of the base substrate, and each such rectangular shaped tile area having a pair of parallel top and bottom edges and a pair of parallel left and right edges; and   a first plurality of overlapping and pseudo-randomly generated and positioned mixed collection of blobs, splotches, drops, spots, globules, and blotches each comprising color pigments restricted to a theme, and each and all disposed on the outer side of the base substrate;   a message encoded and encrypted and affecting a pseudo-random generated and positioned collection of blobs, splotches, drops, spots, globules, and blotches such that the message is demodulateable, decryptable, decodable, and readable by an authorized digital imaging camera supplied with a pseudo-random number code used originally in the pseudo-random generation and positioning of the blobs, splotches, drops, spots, globules, and blotches;   wherein, the first plurality are identically repeated in the rectangular shaped tile area, and seamlessly blend each of their overlapping and unsystematically positioned blobs, splotches, drops, spots, globules, and blotches across borders of the top and bottom and left and right edges of any conjoining rectangular shaped tile area.   
     
     
         2 . The pseudo-random steganographic camouflage of  claim 1 , further comprising:
 a second plurality of distorted-grid-grid positioned and consistently smaller sized blobs, splotches, drops, spots, globules, and blotches each comprising contrastingly darker-than-average color pigments restricted to muted flat earth tones of shades of gray, drab green, brown, and tans that together overlay a few larger areas of the first plurality and that faintly emulate a visual appearance of a fabric wave on which the first plurality is disposed on the outer side of the base substrate.   
     
     
         3 . The pseudo-random steganographic camouflage of  claim 1 , further comprising:
 a pressure sensitive adhesive that covers the inner side of the base substrate opposite to the outer side on which the first plurality is disposed;   wherein, the base substrate includes a polyethylene-coated textile fabric cut into linear strips and coiled into rolls of tape.   
     
     
         4 . The pseudo-random steganographic camouflage of  claim 1 , wherein, the base substrate comprises Mylar plastic sheeting cut into blankets or tarps. 
     
     
         5 . The pseudo-random steganographic camouflage of  claim 1 , wherein the first plurality of overlapping and unsystematically positioned blobs, splotches, drops, spots, globules, and blotches are such that each constituent comprises a unique proportioned combination within any one rectangular shaped tile area of color pigments. 
     
     
         6 . The pseudo-random steganographic camouflage of  claim 1 , wherein the first plurality of overlapping and unsystematically positioned blobs, splotches, drops, spots, globules, and blotches are such that each constituent comprises a unique shape within any one rectangular shaped tile area. 
     
     
         7 . The pseudo-random steganographic camouflage of  claim 1 , wherein the first plurality of overlapping and unsystematically positioned blobs, splotches, drops, spots, globules, and blotches are such that each constituent has an area size in the range of 2% to 20% of the area size of any one rectangular shaped tile area. 
     
     
         8 - 13 . (canceled) 
     
     
         14 . A camouflage sheet, comprising:
 a means for encoding a message on a sheet encoded and encrypted as a pseudo-random generated, positioned, and deposited as a variety of color pigments in a collection of blobs, splotches, drops, spots, globules, and blotches;   wherein, the message is demodulateable, decryptable, decodable, and readable by a digital imaging camera supplied with an authorizing pseudo-random number code;   wherein, the authorizing pseudo-random number code is used originally in the pseudo-random generation and positioning of the blobs, splotches, drops, spots, globules, and blotches.   
     
     
         15 . The camouflage of  claim 14 , wherein:
 the variety of color pigments suit a particular camouflage scheme and function to visually obscure anything hidden behind the sheet.
