Information, image and media encryption is a method for preventing misuse of adversaries. Because encryption and decryption normally need too complex computation. Visual cryptography is a method in witch decryption is performed with used via human visual system. In the traditional scheme; one secret image is divided between two shares so that by stacking the two shares secret image appears. One drawback of this scheme is the size of the shares is 4 times the size of the main secret image and transmission of the shares through internet needs too storage space and more bandwidth.
