A Survey on Cloud Storage Privacy Preserving Public Auditing for Regenerating Code

Cloud is a new way to store large amount of data. In cloud computing, data owners host their data on cloud servers and users can access the data from cloud servers. By data outsourcing, users can be relieved from the burden of local data storage and maintenance. But because of the large amount of data on the cloud it increases privacy challenges against data loss and hacking. For earlier it uses regenerating code while providing fault tolerance against data loss. But because of the fault tolerance the data owner need to always stay online to verify the user data. But challenges are providing integrity of the data. Public audit ability for cloud storage allows users to ask third party auditor (TPA) to check the integrity of the data. Here it analyzes various issues and challenges regarding the data privacy when the data is stored on the cloud. In the various papers it gives various techniques regarding privacy preserving public auditing using the key signature process of secured cloud storage.
