摘要
In this paper, a new (k, n) threshold Secret Image Sharing Scheme (SISS) is proposed. In the proposed scheme the secret image is first partitioned into several non-overlapping blocks of k pixels. Every k pixel is assumed as the vertices of a complete graph G. Each spanning tree of G is represented by k pixels along with Priifer sequence and used to form k pixels of a share image. The original secret image can be restored by k or more shares and cannot be reconstructed by (k-1). The experimental results indicate that the proposed SISS is an efficient and safe method.
