Plausibly Deniable Covert Communication via Saved Game State: Capacity and Feasibility

Trilobyte is a system that hides encrypted data inside saved game files from single-player games, then shares this data between users through cloud-synchronized gaming accounts as a way to communicate secretly in heavily censored countries. The system can hide up to 5.3 MB of data per hour of gameplay and allows users to remove traces of communication after each use, making it harder to detect even if someone physically inspects a device or controls the gaming platform.
