Single-Share Password-Protected Visual Cryptography via Cellular Automata

http://demonstrations.wolfram.com/SingleSharePasswordProtectedVisualCryptographyViaCellularAut The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. Drag the image at the bottom-right corner to the left. This shows how manually overlapping the two shares can be used in visual cryptography. This novelty of this Demonstration is that one of the shares is a snapshot of a rule-30 cellular automaton (CA)... Contributed by: Roman V.
