Abstract
This paper focuses mainly on the different kinds of image encryption and decryption techniques. In addition focuses on image encryption techniques, As the use digital techniques for transmitting and storing images are increasing,it becomes an important issue that how to protect the confidentiality, integrity and authenticity of images. There are various techniques which are discovered from time to time to encrypt the images to make images more secure. This paper presents a survey of over 25 research papers dealing with image encryption techniques scrambled the pixels of the image and decrease the correlation among the pixels, so that we will get lower correlation among the pixel and get the encrypted image. In this paper a Survey of Different Image Encryption and encryption techniques that are existing is given. It additionally focuses on the functionality of Image encryption and decryption techniques.
