Survey on security and privacy preserving public auditing for content storage in cloud environment

Cloud Computing provides the means of sharing various resources over the internet. Using storage as a service user can store as well as share the data remotely. The cloud data storage has many benefits over local data storage. Users should be able to use the data in cloud storage as if data is local, without worrying about the need to verify its integrity. But a challenge is providing data integrity. Public audit ability for cloud storage allows users to ask third-party auditor(TPA) to check the integrity of data. This paper discusses various issues related to privacy when user stores data in the cloud. Here we are going to analyze the techniques of providing privacy and security to data in cloud. By providing privacy-preserving public auditing using ring signature process secure cloud storage system can be implemented.
