Implementation of Public Auditing for Privacy Preserving in Secure Cloud Storage

Cloud computing area provides solution to the problem of limited storage using which a user can remotely store his or her data and enjoy the on demand high quality applications and services from a shared pool of configurable computing resources without handling the burden of local data that is being stored and maintained but the major fact is a user no longer possess the outsourced data that makes the data integrity protection in cloud computing environment as a formidable task for the users who posses constrained computing resources which pretends to use the cloud storage as if it is local without worrying about the need to verifying the data integrity by enabling public audit ability for cloud storage as it is considered to be critical where a user can resort to a third party auditor (TPA) to check the integrity of the outsourced data and be worry free. The vulnerabilities toward user data privacy introduce no additional online burden to user and in this paper we propose a secure cloud storage system that supports privacy preserving public auditing technique which is further extended to perform audits for multiple users simultaneously and efficiently by implementing extensive security and performance analysis which is proved in the proposed scheme which is provably secure and highly efficient.
