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.
