Novel basis matrix creation and preprocessing algorithms for friendly progressive visual secret sharing with space-efficient shares


The traditional k out of n Visual Secret Sharing (VSS) scheme encodes a secret binary image into n shares of random pattern. If the shares are printed onto transparencies, the secret image can be visually revealed only when a subset of k or more transparencies are stacked together otherwise nothing will be revealed. Progressive Visual Secret Sharing (PVSS… (More)
