A Flexible Auditing Mechanism for Storages in Cloud Computing

Saranya C, Vinoth P

In recent years, Cloud Computing has achieved greater heights. Cloud storage is more preferable than normal local storage, as when we use global internet based storage, it is easy to use wherever we go. But these cloud infrastructures are prone to threats like Cloud Service Provider may behave unfaithful towards the users data and also users may faulty perform improper operations that leads to loss of data. The solution for the above problem is that a Flexible Auditing Mechanism was proposed which allows a Third Party Auditor (TPA) to verify the integrity of data stored in the cloud .It uses the fragment structure and secure tag generation method for periodic sampling audit process .It also supports audit for dynamic operations. This audit service can provide public auditability without downloading raw data and protect privacy of the data. Therefore, through this audit system the dynamic data operations and timely anomaly detection can be supported at low storage and communication cost.
