Recursive Visual Cryptography Scheme
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
This Demonstration implements a recursive visual cryptography scheme, specifically using two images (main image and recursive image) and two shares. Move the shares around to reveal the main image and the recursive image. If finding the recursive image turns out to be difficult, click the button to reveal it.
