An Efficient and Secure Data Storage Using Two Different Cloud Storage Technique

Abstract

Distributed storage empowers clients to remotely store their information and appreciate the on-request excellent cloud applications without the weight of nearby equipment and programming administration. In spite of the fact that the advantages are clear, such an administration is additionally giving up clients' physical ownership of their outsourced information, which definitely postures new security dangers toward the rightness of the information in cloud. Sensitive data is stored in the cloud, the corresponding private information may be exposed to cloud servers. Beside data privacy, client frequent queries will certainly and gradually reveal any private information on data statistic properties. Thus, data and queries of the outsourced database should be protected against the cloud service provider. In this research enhanced Shared-Ownership file access control Model. Our proposed secure database system includes a database administrator, and two non-colluding clouds. In this model, the database administrator can be implemented on a client side from the perspective of cloud service. The two clouds, as the server side, provide the storage and the computation service. The mechanism guarantees that knowing either of these two parts cannot obtain any useful privacy information, to conduct a secure database, data are encrypted and outsourced to be stored in one cloud, and the private keys are stored in the other one cloud. In our scheme, the knowledge of stored database and queries is partitioned into two parts, respectively stored in one cloud. Security analysis demonstrates that the protection of numerical data is unambiguously ensured against cloud suppliers in our proposed system.
