\textsc{PrivScope}: Task-scoped Disclosure Control for Hybrid Agentic Systems

In three linesPrivScope is an on-device payload governor enforcing task-scoped disclosure at the local-cloud boundary for hybrid agentic systems. On 100 medical-booking workflows, it eliminates profile leakage (0.0% vs 17.7%), halves attacker re-identification (23.1% vs 64.3%), and preserves task success without cloud-side changes across GPT-4o-mini and Gemini 2.5 Flash.
