Abstract

In this paper, we propose a method such that a secret image is shared by n shadow images, and any r shadow images (r≤n) of them can be used to restore the whole secret image. The size of each shadow image is smaller than the secret image in our method. This property gives the benefit in further process of the shadow images, such as storage, transmission, or image hiding.
