Polynomial-based secret sharing scheme based on the absolute moment block truncation coding technique

Secret sharing is a technique that can distribute partial secret information (also called 'shares') to a specific group member. These individual shares are of no use on their own, but they can reconstruct the original secret information when the members collect all of the shares. In this paper, we proposed a novel, polynomial-based, secret sharing scheme using the absolute moment block truncation coding technique block truncation coding (AMBTC) compression technique. By using simple, exclusive-OR operations, the group members can easily recover the secret image with 100% correctness. Experimental results demonstrated that the AMBTC-compressed image in our scheme had the same quality as the original AMBTC scheme, but the compression ratio in our scheme was better than that of the original AMBTC scheme.
