Visual and Audio Cryptography
Overview
The secret sharing (SS) scheme is a cryptosystem which encrypts a secret into multiple shares so that any qualified combination of shares can reconstruct the secret, while no forbidden combination of shares reveals any information about the secret. The visual secret sharing (VSS) scheme encrypts a visual secret into visual shares so that humans can reconstruct the visual secret with their eyes by superposing a qualified combination of visual shares each printed on a transparency. This work proposes VSS schemes in which arbitrary visual secrets can be associated with arbitrary combinations of visual shares.
