A Framework for Context-Aware Services Using Service Customizer

Abstract — In order to call a context-aware service, a service requester has to reveal his contextual information to a service provider or a context manager, which may jeopardize his privacy and security. Moreover, if the client's context changes over time, a context-aware web service must be called frequently with the updated context values. In this paper, we propose a service customizer agent at the client's side and a service provider that generates general service responses and service customization knowledge. The customizer agent uses the knowledge to personalize the general service response based on the client's context. In addition to offering innovative context-aware services, the proposed approach improves the privacy and security features of web services
