Abstract :
In this paper, we share and embed secrets with images using secret expansion in such a way that secrets are easily reconstructable from the two shares, but getting any one share reveals no information about the secrets. After the reconstruction scheme, the original image can be completely recovered. The proposed scheme is simple without using any data compression and without any extra information.
