Visual cryptography is one of the techniques that can be used for securing image-based secrets. The scheme visual cryptography is used to encrypt a secret image or document by breaking into shares. In order to take the advantage of this property, the third party can recover the secret image if the shares of secret image are passing in sequence over a network. This paper presents an approach to encrypt generated image shares of visual cryptography using public key encryption. The authors used RSA algorithm in order to provide the double security of the document.
