Outsourcing data to a remote Cloud Service Provider (CSP) is a growing trend for numerous customers and organizations alleviating the burden of local data storage and maintenance. Moreover, customers rely on the data replication provided by the CSP to guarantee the availability and durability of their data. Therefore, Cloud Service Providers (CSPs) provide storage infrastructure and web services interface that can be used to store and retrieve an unlimited amount of data with fees metered in GB/month. The mechanisms used for data replication vary according to the nature of the data; more copies are needed for critical data that cannot easily be re-produced. This critical data should be replicated on multiple servers across multiple data centers. On the other hand, non-critical, reproducible data are stored at reduced levels of redundancy. The pricing model is related to the replication strategy. Therefore, it is of crucial importance to customers to have a strong evidence that they actually get the service they pay for. The system propose a map-based provable multi-copy dynamic data possession (MB-PMDDP) scheme. This scheme provides an adequate guarantee that the CSP stores all copies that are agreed upon in the service contract. Moreover, the scheme supports outsourcing of dynamic data, i.e., it supports block-level operations such as block modification, insertion, deletion, and append. The authorized users, who have the right to access the owner’s file, can seamlessly access the copies received from the CSP. We give a comparative analysis of the proposed MB-PMDDP scheme with a reference model obtained by extending existing provable possession of dynamic single-copy schemes.
