Abstract:
In enterprise-based collaborations, humans working in dynamic overlapping teams controlled by their respective enterprises, share personal context and team related context for accomplishment of their activities. Privacy of personal context becomes vital in this scenario. Personal context contains information that user may not want to share, for example, her current location and current activity. We propose a role-based dynamic sharing control model which is owner centric and extends role-based access control model. We provide privacy of owner’s personal context by separating it from team related context through the use of owner defined roles. Owner has full control of her personal data and is able to dynamically change her own access rules facing any new situation. We describe a role-based dynamic sharing control architecture which makes use of enterprisedefined roles as well as owner-defined roles for separating user context from team context. We evaluate our approach by providing a
real world scenario, its running example, and implementation as sharing control messenger using Web services in Java.
