Verifying the integrity of data in the cloud remotely is the perquisite to deploy applications. Bowers et al. proposed a theoretical framework “Proofs of Retrievability” to realize the remote data integrity checking by combining error correction code and spot-checking . The HAIL system uses POR mechanism to check the storage of data in different clouds, and it can ensure the redundancy of different copies and realize the availability and integrity checking .
