A framework for context-aware services using service customizer

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.
