SECURE FILE SHARING OF DYNAMIC AUDIT SERVICES IN CLOUD STORAGE

Data integrity and storage efficiency are the two important requirements for cloud storage. Authorized users access the data and share the files in secure manner. The cloud storage service (CSS) relieves the burden for storage management and maintenance. Fragment Structure, random sampling and index table is used to construct the Audit service. These techniques are supported provable updates to cloud outsourced data. The third party auditing allow to save time and computation resources with reduced online burden of the user. Probabilistic query and periodic verification for improving the performance of audit services and also audit system verifies the integrity.
