Privacy Preserving Data Aggregation System using Hilbert Curve for Cloud Data Security

Abstract

The emergence of cloud computing has revolutionized the option of utilization and accessibility of cloud resources among the cloud users for minimizing the cost overhead. A preponderant issue in cloud computing currently is achieving cloud data security. New approaches for achieving  privacy preservation efficiently is the need of the hour. We specially target applications that work on a network of nodes and require secure data aggregation methods in cloud computing. In this paper, a unique methodology for secure data aggregation and transmission is proposed for cloud environment utilizing the proven mathematical model of Hilbert Curve. Experimental analysis is done to analyze the potential of the proposed scheme towards the privacy preservation and accuracy of cloud data. From the results obtained it can be inferred that the performance of the proposed approach looks promising when compared with a few of the existing approaches.
