Public auditing for shared data in cloud storage with an effective user dismissal

Abstract

Cloud computing is an extensive technique which is changing the IT infrastructure swiftly. Data storage and sharing is the foremost and significant research area in cloud computing. Major security issues in cloud storage include missing folders, privacy settings, synchronization issues, etc. One of the topmost exigent research issues in data storage is data integrity. This research study identifies the security issue in data storage and achieves data integrity and privacy by providing public auditing using third-party auditor. To attain an effective key sharing, Shamir’s secret sharing technique is exploited. The proposed system supports an efficient user dismissal by group admin in case if any user is found troublesome while sharing data in cloud storage. To provide a beneficial auditing for users, batch auditing is additionally presented to reduce the auditing time.
