Abstract

The years coming promise to bring new area of information technology, transferring it from scientists minds into reality, on one hand a new paradigm known as pervasive calm, ubiquitous computing, or pervasive computing has the ability to overcome a lot of insufficiencies of the current information systems while on the other hand central blocks of pervasive computing are in direct conflicts with privacy protection fundamentals. Considerable efforts have been taken to cope with this problem but each one had its own shortage. Some just provide one privacy type like location privacy or just identity privacy, some of them were not platform independence, and some resulted to a lot of privacy alarms. In this thesis we proposed a new privacy model in pervasive computing that provides all four privacy types (ID, Location, Time, and content) for the user with high control over private information (User Control over Private Information) and as less privacy warnings as possible (Unobtrusiveness of Privacy Mechanism). To complete the proposed model we showed model privacy policies with XML tags and distributed decision making processes in different layers to provide high scalability. To validate the model, through implementation we showed that model provides “Privacy Policy Expressiveness” with supporting mandatory and discretionary rules, uncertainty handling and conflict resolution. We showed model unobtrusiveness with experimenting and measuring the time user wastes on dealing with privacy sub-system. We showed that our model provides content, identity, location and time privacy that leads to a high level of user control over private information. The model scalability would be granted by using XML as a platform independent format to describe privacy policies with addition of distributed decision making processes. The validation results confirmed that the model supports all four metrics of “expressiveness of privacy policies”, all four metrics of “user control over private information”, and both factors of “scalability”, with less than 10% “unobtrusiveness”.
