Enforcing Privacy of Data Using PDP Scheme in Cloud Environment

With the switch from traditional datacenter towards cloud, demand for cloud storage has been increased rapidly. The major issue about the cloud storage is providing security for remotely stored data and for deploying applications, which led to have abundant consideration on storage security issues. In this paper we report the issues faced while using cloud environment. Further we address a scheme known as Provable Data Possession (PDP) that verifies the integrity of the data stored without having to download it from the cloud when expected. This scheme provides dynamic storage and dynamic operation. The theoretical analysis for this scheme showed its support to multi-user operations. This scheme has overcome the flaw of single block storage.
