Cloud computing technology provides millions of on demand services to its users on internet ranging from infrastructure, software to storage as a service on cloud.Storage service allows its users to outsource large amount of data without directly controlling it and cloud running on the principle of virtually shared servers do not provide users with the storage location. Therefore, various measures can be adopted for maintaining data integrity, security while entering data in cloud. So here, we are having open audit-ability for distributed storage that shoppers will rely on an outsider examiner (TPA) to test the trait of knowledge. This paper offers the problems known with security whereas golf shot away the client's data to the distributed storage amid the examining. During this paper we'll examine totally different systems to fathom these problems to present protection and security of cloud data. There's lots of analysis being created to identify problems associated CSPs and security.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
