Research on Rotation Visual Cryptography Scheme
Zhengxin Fu, Bin Yu · 2009
Based on correlative matrices set and random permutation, a new construction of rotation visual cryptography scheme (RVCS) has been presented, which can be used to encode four secret images into two shares. Experimental results demonstrate that four secrets can be recovered clearly by stacking two shares with different angles and the shapes of the reconstructed images do not have distortions.
