Abstract : With the increasing amount of personal data stored and processed in the cloud, economic and social incentives to collect and aggregate such data have emerged. Therefore, secondary use of data, including sharing with third parties, has become a common practice among service providers and may lead to privacy breaches and cause damage to users since it involves using information in a non-consensual and possibly unwanted manner. Despite the existence of numerous works regarding privacy in cloud environments, users still do not have means to control how their personal information can be used, by whom and for which purposes.
