Abstract

This study presents a new method to achieve progressive image sharing. This new method simplifies the management of multi-secret sharing. The proposed method has all the advantages of traditional visual sharing combined with visual cryptography, namely fast decoding, lossless and prevention of secret disclosure without collecting enough shares. Additionally, it can easily distinguish the group to which the share belongs through friendly meaningful shares.
