Abstract: Behavioural intrusion detection is a frequently used for insuring network security. We expand behaviour based intrusion detection approach to a new domain of game networks. Specifically, our research shows that a behavioural biometric signature can be generated based on the strategy used by an individual to play a game. We wrote software capable of automatically extracting behavioural profiles for each player in a game of Poker. Once a behavioural signature is generated for a player, it is continuously compared against player|s current actions. Any significant deviations in behaviour are reported to the game server administrator as potential security breaches.

Keywords: behavioural biometrics; dissimilarity functions; game strategy; biometric signature; automated identification; intrusion detection; game networks; behavioural profiles; poker; security.
