Abstract
Visual cryptography is an image secret sharing scheme used to encrypt the secret image into several meaningless share images. Later on, the secret image can be obtained while stacking the share images with no computations. However, the secret image cannot be completely reconstructed. In particular domains, it is intolerant any distortions, such as medical image, legitimate, artist, etc. With low computations, lossless image secret sharing is proposed to help completely reconstruct the secret image. During the transmission, it is a risk that some bits in a share image are lost. As a result, the secret image cannot to be completely reconstructed. To meet requirement, it desires a way to authenticate whether the bits are lost. In this paper, a self-authentication mechanism for image secret sharing scheme is proposed. The experiments provide the positive data to show the feasibility of the proposed scheme.
