Cloud Computing offers resources as services that are dynamically provisioned over the internet. The security of cloud computing has always been an important aspect of the quality of service from cloud service providers. The main problem that the cloud computing paradigm implicitly contains is that of secure outsourcing of sensitive as well as business-critical data and processes. One central concern in cloud computing is privacy and integrity of data processes in cloud. By using two or more distinct clouds, risks such as manipulation of data, and other threats associated with process tampering can be reduced. By integrating distinct clouds, the trust assumption can be lowered. Therefore, to provide integrity and confidentiality, the application logic and the data logic is split into two distinct clouds so that no cloud provider will gain the complete knowledge of the user data. The administrator resides in a private cloud, allows only the authenticated users to access the cloud storage. The administrator performs encryption and segmentation of the data to provide data confidentiality.
