A Survey on Data Integrity Methods in Cloud Storage

Cloud computing offers different kind of services to the end user, so that end user can store the data and access it on demand where ever they need it. Now days IT industries are outsourcing their data by storing it remotely in cloud for reducing the load on local storage there by reducing the hardware, software and maintenance cost. In spite of these benefits, the major problem with data storage is that there is no guarantee of data consistency and integrity, which has become a major hurdle for using the services offered by cloud. So this paper surveys existing schemes that proves data integrity and retrievability.
