Current advances in the technology are demanding novel secret sharing techniques. Splitting of textual information into shares is an age old process, wherein image encryption has gathered its own demand in the current technology. Visual cryptography is a technique which encrypts images into shares and has been proved to be different from traditional cryptographic techniques, as it involves less mathematical computations for decryption. Current research concentrates mostly on dividing a single secret into two or more shares. Stacking the shares on each other reveals the secret.
