triptures

I have realized a method that, given three black and white images A, B and C, produces two new images A' and B', in such a way that A' and B' look like A and B, while their superimposition C' looks like C. Is there anyone so kind to visit the page http://www.dm.unibo.it/~frosini/triptures.shtml
and tell me if this method is original?
Thanks a lot for any help.

What you're seeing is a pixel map technique that is nothing more than a limited form of steganography. The idea is not original. This technique, or form of steganography, has been around for decades.
