Improvement in Performance of Visual Cryptography by Dividing in Matrix

Cryptography is the practice and study of hiding information. Modern cryptography intersects the disciplines of mathematics, computer science, and engineering. Until modern times cryptography referred almost exclusively to encryption, which is the process of converting ordinary information (plaintext) into unintelligible gibberish (i.e., cipher text). Decryption is the reverse, in other words, moving from the unintelligible cipher text back to plaintext. A cipher is a pair of algorithms that create the encryption and the reversing decryption. On a similar front like this, they have visual cryptography which deals with the protection and hiding of information which is based on the videos.
