Abstract
In cloud data security storage, when data holders store 1ocally controllable data resources in the cloud, they lose control of data integrity and availability. For data holders, the cloud service provider CSP is untrustworthy, and it may damage the data stored in the cloud or forge and deceive the integrity of the damaged data. Aiming at the data recoverability problem after detecting data integrity damage in cloud data storage, an audit method of optimal storage cloud data recoverability based on regeneration code is proposed. This solution not only supports the third-party audit agency to verify whether the data block is damaged and locate the exact location of the damaged data block, but also realizes the data integrity recovery function. In the process of data processing and auditing, the privacy and safety of data are guaranteed. Experiments have proved that the program has a certain degree of safety and effectiveness.
