The Take Grant Protection Model is a theoretic model of access control that captures the notion of information flow throughout the modelled system. This paper analyzes the problem of sharing information in the context of paths along which information can flow, and presents the number of actors necessary and sufficient to share information, in this model. The results are applied to information flow in a network to reduce the size of the set of actors who could have participated in the theft.
