The Important of Cloud Computing is increasing and it is receiving a growing attention in Scientific & Industrial Communities. Cloud computing is one of the top 10 most important technologies and has a greater possibility in successive years by companies and organizations. Cloud computing implement everywhere, favourable, on demand network access to a shared pool of configurable computing resources (e.g. networks, servers, storage, applications and servers) that can be immediately supply and released with minimal management effort.

Cloud computing emerge as a computational prototype as well as a sharing architecture and its main intention is to provide secure, quick, convenient data storage and net computing services and dispatched all …show more content…

From the viewpoint of data security, which has always been an important form of quality of service, Cloud computing surely poses new challenging security threats for number of reasons. Firstly, traditional cryptographic primitives for the purpose of data security protection cannot be straight accepted due to users loss control of data under cloud computing. Therefore, verification of correct data storage in the cloud must be attended without accurate knowledge of the whole data. Considering different kind of data for every user stored in the cloud and the requirement of long term continuous security of their data safety, the problem of checking correctness of data storage in the cloud becomes even more challenging.[1]

2 Background of Cloud Computing

Professor John McCarthy, who was a computer scientist who instituted timesharing in late 1957 on modified IBM 704 and IBM 7090 computers, was the developer of Cloud computing. McCarthy around the 60s affirmed, "Computation may someday be organized as a public utility". McCarthy relayed on the support of some corporations who would help him to sell some computing resources through the utility of business model.
Thankfully, some different organizations purchased it for their use of computing resources (storage, processing, bulk printing, and software packages) available at service bureaus. Companies
