A Review on Cloud Data Security and its Mitigation Techniques

Cloud providers offer several storage services for their users in efficient manner. Cloud users are allowed to store their data in cloud server using cloud storage and reduce the burden of storing and retrieving in local machine. The data can be shared by a user in a group and the facility shakes the integrity of the shared data due to access by many users as well as hardware and software for users. It is necessary to ensure the integrity of shared data before using that data for some process as well as the correctness of the cloud storage. Public auditing mechanism is employed to audit the correctness of the shared data. Both data owner and the Third Party Auditor (TPA) can audit shared data integrity without downloading the data from cloud server. This research paper attempts to point out various techniques to solve the privacy and security issues of the data in public auditing scheme in cloud environment.
