Dynamic teams created by different enterprises collaborate to achieve their mutual goals. User-based collaborations for a specific task, within and across teams, result in a new team represented as dynamic collaboration (c). These inter-team and intra-team collaborations are mostly temporary which are based on specific task or goal. Collaborations among different teams, within a team, or across teams can take different forms when some or all of the users belonging to one or more teams

In such a dynamic environment, information sharing and privacy are critical issues for users, their teams and enterprises. We propose a dynamic sharing and privacy-aware model that supports enhanced sharing and preserves the privacy of users, their teams, and enterprises. We extend the widely used Role-Based Access Control (RBAC) model with team and task entities in addition to sharing and privacy data elements. In this model, using context constraints and hybrid access control policy, a user can control what to share with whom in which context conditions. We present a Dynamic Sharing and Privacy-aware Role-Based Access Control (DySP-RBAC) model that extends the RBAC model for enhanced sharing and privacy of information among collaborating users within and across virtual teams.
