An appropriate approach that can enable image encryption and decryption efficiently is formulated in this survey. Maintaining the secrecy and confidentiality of images is a vibrant area of research. Image encryption basically follows two different approaches, the first being encrypting the images through encryption algorithms using keys; the other approach involves dividing the image into random shares to maintain the images secrecy. The limitation of first approach is heavy computation cost and key management issues. Similarly, the poor quality of the recovered image from the random shares limits the applications of the second approach.
