This is just a thought, fellow autists let me know if you see any value in this:

Steganography ie the art of hiding in plain sight, cryptography ie art of encrypted messages, QR-codes, binary coding and art.

Lets suppose there is a pedo who by nature is usually well versed on the needed level of secrecy and identity protection over cp issues wants to communicate with others.

He knows regular and encrypted messages are monitored electronically at all times, and decides to up his game a bit.

He then uses art as a canvas to transmit messages. He could utilize an algorithm based system little like QR-codes, but more like Artcodes by Horizon.

He then creates art, a collage, a photo, cd-cover, coaster, mural, painting or floor tiles, bathroom tiles wallpapers etc etc. that has a code hidden in.

It could be based on region, boundaries and blobs, binary code easily passable as magazine cover imagegig flyer, tweet or instagram image or a painting to the average Joe, but to those in the know it would be easy to crack knowing the method.

Similarly hiding binary or qr coded messages in image files either visibly or in binary/hex etc.

It could be actual images or simply an URL or phone number.

In this way one can even use bold symbolic imagery of cp code words and still attract the attention of those who are not aware of the system.

If confronted, well it's just quirky art dude.

I see a possibility of this theory especially around Pizza Comet imagery. Especially with Artcodes and Storicodes. children's storybooks especially

Surely the spooks all around the globe know of all this and much more, and if not they can thank me for the idea. Digital camo could be scanned from afar to authenticate the troops... Variations are endless.

I can provide links if interested. Try self first.
