Privacy Enforcement Embedded in Mobile Services

Next generation mobile services in business-to-employee (B2E) settings put very high demands on the privacy protection features of contextaware, personalization and adaptation enabling technologies. To this end we propose a middle agent framework that allows parties to securely exchange personal or business sensitive contextual information independently of the available networks. In order to demonstrate our privacy enforcing middle agent framework, we build a scheduling service, in which the middle agents collectively arrange an update of a meeting between employees by adapting location and time on the basis of privacy and scheduling policies of the traveling employees themselves or the companies they work for. We developed and deployed this scheduling service on a LEAP agent platform and used a PDA to communicate with the middle agents on the server using WLAN and GPRS networks.
