When an access decision function denies a data access request by a mission participant in a mission-critical situation, the mission often suffers. In this paper, we propose a sharing control mechanism that computes and executes requests that are mission-related to denied requests. We extend the Flexible Authorization Framework (FAF) with predicates and hierarchies that permit us to specify authorization rules over denied requests and mission-specific relationships. We illustrate our techniques using a prototypical information sharing scenario, namely an emergency first-responder scenario.
