Provable Multicopy Dynamic Data Possession in Cloud Computing Systems

Abstract— Provable Multicopy Dynamic Data Possession in Cloud Computing Systems. Increasingly more and more organizations are opting for outsourcing data to remote cloud service providers CSPs.< Final Year Project 2016 > Customers can rent the CSPs storage infrastructure to store and retrieve almost unlimited amount of data by paying fees metered in gigabyte/month. For an increased level of scalability, availability, and durability, some customers may want their data to be replicated on multiple servers across multiple data centers. The more copies the CSP is asked to store, the more fees the customers are charged. Therefore, customers need to have a strong guarantee that the CSP is storing all data copies that are agreed upon in the service contract, and all these copies are consistent with the most recent modifications issued by the customers.
