"Data-as-a-Service (DaaS) builds on service-oriented technologies to enable fast access to data resources on the web. However, this paradigm raises several new privacy concerns that traditional privacy models do not handle. In addition, DaaS composition may reveal privacy-sensitive information. In this paper, the authors propose a formal privacy model in order to extend DaaS descriptions with privacy capabilities. The privacy model allows a service to define a privacy policy and a set of privacy requirements. They also propose a privacy-preserving DaaS composition approach allowing verifying the compatibility between privacy requirements and policies in DaaS composition."
