Nvidia received 3 granted patents this quarter across 2 categories: Cloud Gaming (2) and Esports (1).
The Cloud Gaming patents cover encryption systems for secure game build distribution, including a hierarchical approach that embeds encrypted keys in filenames and a dual-key method that attaches encrypted content keys as metadata to prevent unauthorized access. The Esports patent describes an AI-powered anti-cheat system that analyzes mouse submovement patterns to distinguish human behavior from automated bot inputs in competitive gaming.
NVIDIA's 2 cloud gaming patents tackle the same core challenge: distributing encrypted game builds securely without relying on a centralized key repository that could become a single point of failure. Both employ envelope encryption techniques that embed encrypted content keys directly within the game files themselves, with one attaching the key as metadata to the content file while encoding the key-encryption key identifier in the filename. This approach creates self-contained, portable encrypted builds that can be distributed through content delivery networks without exposing sensitive game code to end users or requiring constant communication with a central key server.
A single Esports patent addresses cheat detection through biomechanical analysis rather than traditional software signature scanning. The system examines the fine-grained submovement patterns in mouse inputs to identify characteristics that distinguish natural human motor control from bot automation. By focusing on the physical properties of input behavior instead of looking for known cheat programs, the approach makes it more difficult for developers of cheating tools to evade detection through code obfuscation.
