A Self-Authentication Mechanism for a (3, 3)-threshold Secret Sharing Scheme

Secret sharing is widely used in secret image protection since 1979. Image secret sharing schemes are used to encrypt the secret image into several meaningless share images. Later on, the secret image can be reconstructed while collecting the share images. The authentication mechanism is a way to verify whether the reconstructed secret image is authentic. The general authentication might increase the cost of key maintenance. To reduce the cost, this paper proposed a self-authentication mechanism for image secret sharing scheme. In addition, the reconstructed image can be completely reconstructed. The experiments give the positive data to show the feasibility of the proposed scheme.
