Normally, there is an expansion of space requirement in visual cryptography. But if one of the two shares is structured recursively, the efficiency of visual cryptography can be increased to 100%. [5] Some antecedents of visual cryptography are in patents from the 1960s. [6] [7] Other antecedents are in the work on perception and secure ...
