A visual cryptography is one of the secure techniques that can be used to encrypt a secret document or image by breaking down to shares. In the technique of visual cryptography, anyone can visually recover or decode the original image (i.e. secret image) by overlapping the shares without any computation; this property made the visual cryptography distinctive from existing traditional secure methods. In order to take the advantage of this, the third party can recover the secret image if the shares of secret image are passing in sequence over a network.
