In this paper, we focus on multimedia fingerprinting social network, in which multi-user collusion being a powerful attack, where a group of attackers collectively undermine the traitor tracing capability. During collusion, different colluders have different objective thus, the colluders form a social network and an how to achieve agreement on distributing the risk/profit among colluders and ensure fairness of the attack is a crucial question.
