This month's Platforms & Ecosystems category contains 1 granted patent from Las Vegas Sands.
The patent covers a server-side validation system for video games that replays client action logs to verify game integrity. Las Vegas Sands' technology compares game state models in real-time to detect cheating and bugs during gameplay.
Las Vegas Sands received 1 patent for a server-side validation system that checks online game sessions for cheating and bugs without interrupting active play. The system uses isomorphic code to replay compressed sequences of client actions on the server at accelerated speeds, creating a server-side model of the game state that can be compared against what the client reported. This asynchronous approach avoids the performance overhead of running full server-authoritative game logic in real-time while still catching discrepancies that indicate either cheating attempts or software defects. The deterministic state comparison works because both client and server execute the same code, just at different times and speeds.
