A Novel Approach for Protecting Privacy in Cloud Storage Based Database Applications
Authors: ,
Abstract: Cloud computing technology is appealing to many organizations and has become a popular approach to reduce the cost of services. Adoption of cloud storage is limited due to privacy problems while storing and retrieving sensitive information. This paper presents a solution to the privacy by splitting table containing identity and sensitive information into two separate tables, one with identity information and another stores only sensitive information. It provides k-anonymity while performing inserts, select, update and delete operations. The degree of privacy increases with the values of k. In this paper we carry out performance analysis of our proposed scheme for different values of k. Performance analysis shows that the system performance do not degrade significantly for higher values of k. The Regression models of relation between dependent variables like response time, local computation cost, local communication cost and independent variable k have been developed in this paper. This help system designer to identify the degree of privacy required and predict the time required for different database operations. The analysis of results of residual shows that the developed models are good fit for the experimental data.
