Recently, verifiable secret sharing schemes have been proposed to keep participants from providing fake or illegal stego-images. However, the schemes do not consider the recovery mechanism when parts of the information in stego-images are lost or incidentally modified during the transmission process. This paper presents a novel verifiable and reversible secret sharing scheme based on Shamir's scheme, which can authenticate the shares in advance and then recover the inauthentic parts to reconstruct the original secret image. The experimental results provided positive results for the feasibility of the proposed scheme.
