Abstract

The rapid adoption of Cloud in various domains like Education, Science, Engineering, Marketing and Business, face issues when it comes to Medical and Healthcare industry adopting the Cloud. The Compliance and Security of Medical images and Confidential images needs to be secured using suitable approaches so that the image confidentiality is not sacrificed at any instance. The Image encryption aims at achieving ideal NPCR and Entropy values when comparing with the original image, the encryption should be loss-less and identical to original image. The approach towards securing the image can be preserved through modified Fisher Yates Pixel-shuffling algorithm which distorts the structure of the image and increasing the randomness using Binary Transformation further. The prototype was evaluated and the average Entropy was observed to be 7.76 and NPCR was 100% which produces better results in terms of NPCR and compartitively similar for Entropy to that of the other methods.
Keywords: NPCR (Number of Pixel Change Rate), RGB (Red-Blue-Green).
