Cryptography is used for sharing the text securely. Equally visual cryptography is used to share the images securely. The secret image is distributed to the participants using visual cryptography. The participants without much cryptography knowledge can recover the secret image. The extended visual cryptography scheme that contains meaningful shares when compared to the traditional visual cryptography that has random shares. The embedded extended visual cryptography which has the best visual quality when compared to the traditional one.
