Public Auditing Mechanism toVerify Data Integrity in Cloud Storage

Abstract

Cloud remote servers.It gives users a flexible approach to access data that are outsourced remotely via the internet.Cloud users can manage their data without deploying and maintaining storage servers and devices in the local system.Data integrity and confidentiality are the two most vital security concerns over unreliable cloud service providers (CSP).However, the management of data and services by CSP may not fully be trusted by industries/users.While the integrity of data checks whether data stored in cloud server remains intact, confidentiality of data ensures whether the stored data is secure and not disclosed to anyone.In this paper, an approach for ensuring the integrity data in cloud storage server proposed to strengthen the trust of cloud service provider, because of cloud service provider might delete rarely accessed file of users or may try to hide data loss incidents to maintain their reputation and claim that there is no data loss.
