Researchers have developed AgentMark, a novel framework for embedding multi-bit identifiers into the planning behaviors of LLM-based agents. This method aims to protect intellectual property and provide regulatory provenance by watermarking high-level decision-making processes, such as tool and subgoal choices. AgentMark operates by eliciting and modifying the agent's behavior distribution, allowing for utility preservation and compatibility with existing content watermarking techniques, even when agents are accessed via black-box APIs. Experiments across various environments have shown its effectiveness in practical multi-bit capacity and robust recovery from partial logs. AI
