Abstract :
This paper proposes a (2n, 2n) pixel contractible secret sharing scheme which encodes a secret image into 2n share images. Only when the 2n share images exist, can people get lossless secret reconstruction. Meanwhile, the size of each share image is 1/2n of secret image. Thus, it can reduce the storage capacity and network transmission bandwidth. Compared with other methods, this method can not only generate smaller share images but also restore the secret image perfectly.
