DATA SECURITY USING AUTHENTICATION AND AUTHORIZATION IN CLOUD COMPUTING

Cloud computing is one of the general purpose technology. It is mainly used for distributed the data centres, resources and services that are pro-vided by the network or online. In cloud computing, compatibility means ability of computer system to run application program from different seller and to interact with other computers. That is bringing with many challenges of security and privacy. Most of the data store in cloud. Because it is safe and secure then only users will trust on their environment. Now days cloud computing is mainly used in both industrial field and academic field. As the field of cloud computing is growing the new techniques are developing. Security is the big problem for cloud computing clients especially access control. Such as massive traffic handling, service ability, security issues technology, application security. This paper briefly describes the cloud based secure and privacy enhanced authentication and authorization for cloud computing and security.
