Comparative between encryption and decryption of (binary, gray& color) images using optical scanning cryptography

Encryption and decryption play a significant job in the development of the image stockpiling. It is used to achieve the mains of security objectives like secrecy, confirmation, honesty, integrity, and non-renouncement. In this paper we apply an optical scanning cryptography for encryption and decryption on three different type of (binary, grayscale & color) images. It is found that simulation process was great and successful in encrypting all these images, as well as it furnishes protection and security with every step of the optical encryption method.
