Improving Cloud Security by Enhancing Remote Data Integrity Checking Algorithm

Cloud computing is a type of Internet based computing that provides shared computer processing resources and data to computers and other devices on demand. Nowadays, many organizations are moving to cloud storage. Remote data integrity checking is gaining crucial importance in cloud storage recent days. In some application scenarios, the clients have to store their data on multi-cloud servers. At the same time, the integrity checking protocol must be efficient in order to verify the data content and most importantly we have to monitor those data with the help of auditing. The already existing problem is that attackers can hack the information sometimes from cloud even though the data integrity checking protocol was installed, and they didn't maintain auditing technique also. To avoid those issues, we propose a unused successive cloud auditing technique it provides uninterrupted certificates to the user and as well auditing the data which is verified with help of fresh data integrity checking protocol. The data integrity technique will address the issues like if attacker corrupts the data in Multi-Cloud, the proposed continuous auditing method will help the verifier to perform block level and file level checking to ensure this process. Our objective of this work is to provide the secure cloud service and this process to be efficient in all cases which will be illustrated in this paper.
