Streamforce: Outsourcing Access Control Enforcement for Stream Data to the Clouds
As tremendous amount of data being generated everyday from human activity and from devices equipped with sensing capabilities, cloud computing emerges as a scalable and cost-effective platform to store and manage the data. While benefits of cloud computing are numerous, security concerns arising when data and computation are outsourced to a third party still hinder the complete movement to the cloud. In this paper, the authors focus on the problem of data privacy on the cloud, particularly on access controls over stream data. The nature of stream data and the complexity of sharing data make access control a more challenging issue than in traditional archival databases.
