This research has covered three inter-related objectives such as secure transmission of images to public cloud, computationally efficient secure and privacy preserving storage of images in hybrid cloud and content protection mechanism to safeguard interests of the content providers. An extensive review of literature is made to understand present state of the art on computationally efficient, secure and privacy preserving storage and retrieval of images in cloud. The research insights revealed the need for a computationally efficient framework that takes care of secure and privacy preserving...
