Data encryption is a vital application to ensure security in open networks like internet. Image is widely used for various purposes and one of the most popular formats of data on the web. Different image encryption algorithms are proposed so far to generate encrypted image so that it is so difficult make prediction of pixels value by attackers. This paper proposes a new framework for image encryption, a layer based method combining some most efficient image encryption algorithms. It is tried to take all encryption concerns into consider, achieve highest possible level of security while cost is already acceptable. The proposed method provides different security level to blocks of varied significance in image to consume less computational resources. Various analysis and experiments such as histogram, correlation coefficient, entropy, and computational time revealed that significant promotion in security has been achieved without compromising on the computational time.
