Abstract

Background: Cloud computing is a model whereby users access compute resources from a service provider through internet. The Cloud Computing has great capability to boost productivity and minimize cost, hence many organizations are migrating to the new technology, but at the same time it constitutes many security risks and challenges. Methods: DNA and ID base cryptography methods are used for cloud computing security. Findings: Cloud computing can address the problems when user moves from single cloud to multi-clouds. In this paper, we provide an extensive survey of cloud computing ­security challenges and different technologies taken to tackle the issues. Improvements: Highlighting the security issues of cloud computing, the proposed system is, DNA technology and JPEG Zigzag coding with an encryption scheme. We conclude the paper with a critical analysis of challenges that have not yet been fully met, and highlight directions for future work.
