Dynamic content-based cloud data integration system with privacy and cost concern

Although a lot of research is currently taking place in the cloud computing technology itself, there is an equally urgent need for understanding the cost effective issues surrounding cloud. In this paper we present a dynamic content-based inter-cloud data integration system with privacy and cost concern. Users can evaluate the privacy risk value based on the content (input data or intermediate searching results) which are generated during runtime, in the meanwhile, comparing with existing data sharing techniques, our method is more practical as the cost for technical supporting privacy must be considered in the commoditized cloud computing environment.
