Online gaming is increasingly threatened by the presence of cheaters, undermining the integrity and enjoyment of competitive play. Traditional anti-cheating measures often react too slowly, addressing issues only after a match has concluded and the damage is done. The article explores a more proactive approach by leveraging real-time data and artificial intelligence to detect and neutralize cheaters instantly. This is achieved by identifying inhuman behavior patterns, such as impossibly fast reaction times that point to the use of cheats like aimbots. The system uses streaming SQL and historical data analysis to distinguish between skilled players and cheaters, reducing false positives. When a high-confidence cheat pattern is detected, a GenAI agent, known as the "Fair Play Guardian," intervenes by isolating the cheater in a "shadow lobby," preserving the match's integrity for other players. This real-time intervention not only protects the gaming experience but also expedites the process of permanent banning by providing comprehensive evidence for human moderators.
