摘要：In a multi-secret image sharing scheme, participants are able to share multiple secret images such the way that each secret image can be reconstructed according to the corresponding access structure. In this paper, employing Chan and Chang's multi-secret sharing, we propose a new multi-threshold secret image sharing scheme. In the secret image sharing process, based on the generalized CRT, secret values are produced according to the associated access structures. The shadow images can be generated by embedding the secret values into a cover image using the quantization operation. The new scheme allows a qualified subset of participants to retrieve the related secret image. Moreover, any monotone access structure can be realized with a deletion procedure. The experiments demonstrate that secret images can be recovered without distortion. Besides, the quality of the shadow images is satisfactory and the capacity of embedded secret values is acceptable especially under binary images.
