In response to the issues of second-hand sharing and repeat delegation of the digital content in existing multimedia social networks, this paper proposed a novel formalized delegation model for multimedia social network. In accordance with this model, delegators can independently lay down delegation policies. Further, related delegation constraints and strategies were identified to solve delegation conflicts. When a conflict arises among several delegations, strategies could be used to solve the conflict. This delegation model can control the authorities and are delegated consistently until the authorization expires or is revoked. And also, the paper presented essential security policies that lead to revoking different authorities. A use case of real multimedia social network further verified the efficiency and effectiveness of the proposed model.
