Image encryption consists of transmitting the image securely over the network so that no unauthorized user can decrypt the image. Image encryption, video encryption, chaos based encryption have applications in many fields, including Internet communication, transmission, medical imaging. Cellular medicine and military communication, etc. The evolution of encryption advances towards a future of infinite possibilities. The image data has special properties such as volume capacity, high redundancy and high correlation between the pixels. Encryption techniques are very useful tools to protect secret information. Encryption will be defined as the conversion of a simple message into a form called ciphertext that can not be read by any person without decrypting the encrypted text. Decryption is the reverse process of encryption, which is the process of converting the encrypted text into your original unformatted text.
