This month's cloud gaming and streaming category includes 2 granted patents from Nvidia and South Park Digital Studios, with 1 patent each.
Nvidia's patent addresses security in cloud gaming through a hierarchical encryption system that embeds encrypted keys directly in game build filenames, allowing secure distribution while preventing end users from accessing the underlying builds. South Park Digital Studios' patent covers a live game intervention system that enables a second device to remotely control aspects of another player's active cloud gaming session in real time.
Nvidia received 1 patent that redesigns how encrypted game builds are secured and distributed through cloud delivery networks. The system embeds an encrypted content key as metadata within the game build itself and encodes a key-encryption key identifier in the filename, creating self-contained packages that eliminate the need for a central key repository. This approach removes the single point of failure that conventional content delivery network encryption relies on while making encrypted game builds portable and independently distributable.
South Park Digital Studios received 1 patent for a system that lets one player remotely alter another player's live cloud gaming session through an external device. The technology creates a cloud-mediated handshake between two devices, allowing a person on the second device to inject gameplay changes dynamically while the first player's session is running. This differs from standard in-game mechanics because the interventions come from an external human controller rather than from the game's own rule engine or pre-scripted events.
