Title
A threat-based privacy preservation system in untrusted environment
Abstract
In an untrusted environment, it is hard to ensure that all the available technologies are being used to protect data privacy. Once user's data is hosted outside of his/her local computer, a degree of control over his/her privacy information may be lost. Consequently, a variety of threats may arise and result in hazards to the user. For that reason, users want to disclose privacy data in a minimum way so that the potential threats to their data can be also minimized. Thus, the importance of privacy data elements must be verified by individual user. However, user may not be able to achieve this task if the threats are not obvious to the user. To address this problem, in this paper, we present a threat-based privacy preservation system that helps a user to evaluate the importance of privacy data and the risk of disclosing it. In our system, users can specify their privacy preferences by setting penalty values on potential threats. Through a goal-oriented approach, our system can select proper services for users to restrict data disclosure by which the potential threats to users can be minimized.
