A Survey of Data Integrity Verification Techniques in Cloud Services

With the growing volume of business,more and more enterprises are accepting the cloud computing,with data migrating from the local to the cloud.This new data storage model also causes many security problems,among which ensuring the integrity in the cloud server is a critical one.The data owner needs to have a stable,safe,reliable integrity audit framework,for auditing the integrity of the data in the cloud server and availability.The cloud computing environment data integrity and security model,system model and the research status of cloud storage data integrity audit are expounded,with focuses on analyzing some classical solution through scheme comparison.It is pointed out that the advantages and defects exist in the current scheme.Refining data integrity verification in cloud services is currently still facing the challenges of security and privacy problems,and the trend of research in this field are discussed.
