Privacy-aware access control through negotiation in daily life service

Abstract

As users are participating in various social contexts, some projects such as MobiLife and MyLifeBits are developing a facility to commence daily life service. This enables users to store all their daily events which can be collected using their mobile device. These data can be shared with other people or some service providers only if the user agrees. However, in the cases of inter-domain web service usage or sharing their data with others, there are some potential problems about privacy. To solve these problems, we propose a new method, privacy-aware access control through negotiation process (N-PAC). This method enables a user to accomplish self-determination and self-control of personal information in more realistic application environments. © 2008 Springer-Verlag Berlin Heidelberg.
