Design and Exploration of Mobile Game Anti‑Fraud Systems

The mobile gaming industry faces a rapidly evolving black‑market chain that includes tool producers, intermediaries, and downstream consumers such as illicit studios and compromised player accounts, all of which threaten game integrity.

Common fraud forms include content‑security abuses (e.g., nickname and signature scams), script and cheat distribution for FPS, MMO, and card games, resource‑trading monopolies, initial‑account sales, and unauthorized recharge (代充) schemes.

The proposed anti‑fraud system separates content‑security from core game modules, employing both real‑time detection (evaluating individual actions like registration, payment, and social interactions) and offline analysis (leveraging accumulated behavioral data) to assign risk scores to entities such as accounts, devices, and IPs.

During early gameplay, the system focuses on low‑cost, low‑impact controls—such as mandatory tutorials, simple CAPTCHAs, and basic identity verification—while later stages employ more granular, game‑specific models for FPS cheats, resource‑trading detection, and card‑game reward abuse.

Risk mitigation balances strict enforcement with player experience: early violations trigger warnings or minor restrictions, whereas repeated or severe offenses lead to account bans or resource penalties, with the overall strategy adapting to the game's lifecycle and regional considerations.

Operational insights highlight the importance of decoupling detection from enforcement, maintaining high cohesion and low coupling in system design, and integrating explainable machine‑learning models that align with business objectives.

The Q&A section addresses international identity verification, team sizing for security operations, the financial impact of recharge fraud, detection of unknown cheats, and handling of account‑trading marketplaces.
