摘要:	A (k,n) secret image sharing approach shares a protected image to n shared images and gathering k shared images can reconstruct the original image. This paper solves the secret image sharing problem by a geometry secret sharing strategy named the Blakley scheme. We first partition the protected image into non-overlapping sets of k pixels. Every k pixels forms a point under a k-dimensional space and the set solution to each generated affine hyperplane intersecting in this point stores as one shared image. Gathering k shared images can calculate the reconstructed image that is consistent with the protected image. We also present an efficient hyperplanes selection strategy. The experimental results demonstrate that the proposed approach is a simple but efficient secret image sharing approach.
