Privacy Preserving Third Party Auditing For Dynamic Data
In cloud storage system, the client stores their data in the server without keeping a local copy. Hence, it is of critical importance that the client should be able to verify the integrity of the data stored in the remote un-trusted server. Existing protocols support both features with the help of a third party auditor. If in case, the third party auditor modifies any part of the client's data, the client should be able to detect it; furthermore, any third party verifier should also be able to detect it. In case a third party verifier verifies the integrity of the client's data, the data should be kept private against the third party verifier.
