Personalized Services with Negotiable Privacy Policies
نویسنده
چکیده
This paper examines how negotiation techniques can resolve the trade-off between service providers’ personalization efforts and users’ individual privacy concerns, how they lead to efficient contracts, and how they can be integrated into existing technologies to overcome the shortcomings of static privacy policies. The analysis includes the identification of relevant and negotiable privacy dimensions. A detailed privacy negotiation scenario from multi-channel retailing is examined. Based on a formalization of the user’s privacy revelation problem, we can solve the selection of the efficient privacy level as an optimization problem. Finally an extension to P3P is proposed that allows a simple expression and implementation of negotiation processes. Support for this extension has been integrated in the Mozilla browser. Author
