A Secret Image Sharing Scheme Based on Bidimensional Cellular Automata
Chen Gui-qiang · Modern Electronics Technique · 2008
Based on the bidimensional cellular automata,a new secret image sharing scheme is proposed in this paper.The secret image is considered as one of the initial configurations of the bidimensional cellular automata,The n shadow images of the secret image are made by the bidimensional reversible cellular automata with memory of ordern.The backward iteration of the bidimensional reversible cellular automata with memory of order n is used to recover the shared secret image.Analysis show the proposed scheme can be implemented easily,and is a computationally secure and perfect(n,n) scheme.
