Mohit Kumar, Anju Chahal · International Journal of Computer Applications · 2014
Images have a significant role in communication, entertainment and business etc.Images may convey confidential information, so various image encryption algorithms ensure security of secret images.The correlation coefficient in encrypted image is an important security criterion to measure the level of security of encrypted image.Various factors can affect the correlation coefficient in the encoded image.So, this work reveals the effect of image encryption method and the size of an image on correlation coefficient in the corresponding encrypted image.
