Design and Implementation of Mobile User Agreement Service

Different from the previous web which provides a service the company want to serve a user, Web2.0 era enables a user to participate in the process of generating and sharing of resources/services. However the public´s concern of the privacy infringement is growing and the worse is that traditional methods do not protect the privacy in various situations. User Interaction is a method to define policies for privacy according to the context. In case of sharing user´s attributes, the most reliable method is to get a user´s agreement explicitly. We also choose mobile device to interact with the user. Proposed architecture provides two major functions; acquiring a user´s agreement to serve the user´s current request, and reuse of wired PKI on the mobile device. Proposed architecture was developed on the WIPI platform.
