AMACBASED BLOCK CHAIN FOR EFFICIENT DATA INTEGRITY VERIFICATION SCHEME IN MULTI- CLOUD STORAGE

Abstract

— Massive data access and storage are made possible by cloud storage services, which also lowers the cost of managing massive data volumes. Users can use cloud storage's data integrity verification scheme to help verify the accuracy of data that has been outsourced. Whilethird-partyauditors(TPAs)canbehiredtohandle data integrity verification through public data integrity verification schemes, there are still numerous security andoperationalissueswithcentralizedTPA.Researchers have attempted to use blockchain technology to address the centralization issue with conventional methods in recentyears,buttheseplansignoretheissueofefficiency degradation brought on by the use of blockchain technology. An effective data integrity MAC verification method for multi-cloud storage services is proposed in this work.
