An Enhanced Security Technique for Storage of Multimedia Content over Cloud Server

摘要

Cloud computing is an emerging computing paradigm in which resources of the computing infrastructure are provided as services of the internet. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. With the development Internet multimedia co mputing has emerged as a technology to generate, edit, process, and search media contents, such as images, video, audio, graphics, and so on. Multimedia cloud co mputing has the potential for tremendous benefits, but w ide scale adoption has a ra nge of challenges like Multimedia and service heterogeneity, QoS heterogeneity, Network heterogeneity, Device heterogeneity ,Security, Power Consumption that must be met. But data security and access control is the main challenge when users outsource sensitive data for sharing on cloud servers which is not within the same trusted domain as data owners. To keep sensitive user data confidential against untrusted servers, various methods have been proposed in the literature. This paper explores a new method which is a combination of roll based access control with advanced encryption algorithm (a combination of RSA and two fish),signature verification to enhance security when storing text, image ,audio ,video files onto cloud server
