In this paper, the authors propose Provable Data Possession (PDP), a probabilistic proof method for CSPs to prove the data integrity without downloading the whole data. In recent years, cloud computing has rapidly expanded as an alternative to conventional computing model since it can provide a flexible, dynamic, resilient and cost effective infrastructure. When multiple internal and/or external cloud services are incorporated, they can get a distributed cloud environment, i.e., multi-cloud. Multi-cloud is the extension of hybrid cloud. When multi-cloud is used to store the clients' data, the distributed cloud storage platforms are indispensable for the clients' data management.
