In this paper we describe a decision process framework allowing an agent to decide what information it should reveal to its neighbours within a com- munication graph in order to maximise its utility. We assume that these neigh- bours can pass information onto others within the graph, and that the commu- nicating agent gains and loses utility based on the information which can be in- ferred by specific agents following the original communicative act. To this end, we construct an initial model of information propagation and describe an optimal decision procedure for the agent.
