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.
