Behavioral Privacy Leakage in Agentic Negotiation: Formalizing and Mitigating Inference Attacks via Randomized Policies
This paper was accepted at the AI4TCI (Workshop on AI for Secure and Trustworthy Critical Infrastructure Systems) Workshop at the International Conference on Availability, Reliability and Security (ARES) 2026. Autonomous negotiation agents are increasingly deployed in high-stakes settings such as insurance and procurement. While cryptographic techniques protect explicitly disclosed constraint values, they fail to address a subtler threat: behavioral privacy leakage, where an adversary infers private constraints from observable negotiation dynamics such as concession trajectories, timing, and…
The increasing deployment of autonomous negotiation agents in high-stakes environments necessitates a deeper understanding of their security vulnerabilities and privacy implications.
This research highlights a critical, often overlooked aspect of AI security—behavioral privacy leakage—which can undermine trust and expose sensitive information in automated decision-making systems.
The explicit formalization and mitigation strategies for behavioral privacy in AI agents elevate the discourse beyond direct data breaches to subtler forms of inference attacks, leading to more robust AI design principles.
