Cheat detection and prevention in P2P MOGs

Scalability and fairness are keys to the success of massively multi-player on-line games. The first is necessary for the technical viability of the game while the latter is required for the wide adoption by players. Although they achieve better scalability, peer-to-peer games are more prone to cheating as players have access to and manipulate sensitive game data [2]. While in centralized games cheat detection and prevention can be achieved by having the server verify the players' actions and reduce the information sent to players to the minimal amount required to render the game world, in decentralized games, it is more difficult as natural trade-offs between respon siveness, scalability, verification and information disclosure appear together with the issues of trust and collusion.
