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 communication. [8] [9] Visual cryptography can be used to protect biometric ...

In cryptography, a secret sharing scheme is verifiable if auxiliary information is included that allows players to verify their shares as consistent. More formally, verifiable secret sharing ensures that even if the dealer is malicious there is a well-defined secret that the players can later reconstruct.
