Cloud computing is a vital part of any little or huge organization. With cloud storage service clients can remotely store their information to the cloud and realize the information sharing to others. Information redistributing has the danger of delicate information getting breached. Remote information trustworthiness auditing is proposed to ensure the integrity of data stored in the cloud. In some regular cloud storage frameworks, for example, Electronic Health Records (EHR) frameworks, the cloud document may contain some delicate data which must not be modified. This paper proposes a novel privacy preserving system that supports reviewing on shared information stored in the cloud. Specifically, hashing algorithm is utilized to compute verification metadata expected to audit the correctness of shared information. A hash signature is created for each record by the data owner and afterward it is transferred. After a document is transferred to the database by the data owner, the auditing mechanism recompute’s signature and contrasts with the local copy signature of the file in data owner side. On the off chance that an interloper or a client breaks the security and alters the open cloud information, the Hashing calculation is performed, and the interloper or client is ended from further accessing the cloud information. This strategy guarantees data integrity in shared cloud data especially for EHR frameworks, substantially more efficient and less calculation cost contrasted with the current framework. Therefore, the information in the cloud is solid and credible.
