Cloud computing is an emerging evolutionary computing model that provides highly scalable services over high-speed internet on a pay-as-usage model. However, cloud-based solutions still have not been widely deployed in some sensitive areas, such as banking and healthcare. The lack of widespread development is related to users' concern that their confidential data or privacy would leak out in the cloud's outsourced environment. To address this problem, the authors propose a novel active data-centric framework to ultimately improve the transparency and accountability of actual usage of the users' data in cloud.
