I went to listen a speech this afternoon, it was about the Multimedia Social Networking. But the orator focused on the Multimedia, which for signal and image processing. He mentioned that traditional social networking players are human or rational machines/nodes. And new players are contents/signal or pixel. That means social networking often achieve by people, however, computers can have social networking as well.
Social network is a social structure made of nodes tied by some types of independency. Users in social network want reward, but they have to pay for.
Users are selfish, they have an event for agreement, then have bargaining, cheating and attacker.

Collusion Attack in multimedia fingerprint.
Colluder: higher risk can get higher reward, lower risk get lower reward.
