Behavioral Privacy Leakage in Agentic Negotiation: Formalizing and Mitigating Inference Attacks via Randomized Policies
Why it matters
As AI agents take on high-stakes negotiation roles in insurance and procurement, a new class of inference attacks—behavioral privacy leakage—exposes hidden constraints through negotiation dynamics alone. This research formalizes the threat and proposes defenses via randomized policies, highlighting a critical gap between cryptographic protection and real-world agent deployment security.
Key signals
- Accepted at AI4TCI Workshop (ARES 2026)
- Focus on autonomous negotiation agents in high-stakes domains (insurance, procurement)
- Threat vector: behavioral privacy leakage via concession trajectories, timing patterns
- Defense mechanism: randomized policies
- Cryptographic techniques alone insufficient for agent privacy

The hook
Autonomous agents have a privacy problem nobody's talking about: adversaries can reverse-engineer your negotiation strategy from how you move.
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…
