Public Verification for Cloud Storage using Block-chain Technology

Abstract

The utilization of cloud storage services provides many advantages for user data management. Data integrity is one of the numerous security issues it raises, though. By using public verification methods, a user may use a third party. The current public verification schemes allow the user to hire an auditor to examine the data integrity on their behalf rather than depending on late  auditors to finish verification. Furthermore, because most public verification systems are due to PKI,  they have a problem with certificate management. We  introduce the first certificate-less public verification  algorithm (CPVPA) against an untimely auditor that is built on a block-chain. The fundamental knowledge is about requiring auditors to add every outcome of a validation as a transaction to a block-chain.
