PrivScope: Task-scoped Disclosure Control for Hybrid Agentic Systems
TL;DR
Hybrid local-cloud agents can inadvertently expose sensitive information when enriching user requests with context before sending them to a cloud language model (CLM). PrivScope was developed to control the disclosure of task-relevant information, minimizing over-disclosure of unnecessary details.
✦ Why It Matters
Engineers can implement PrivScope to enhance data privacy in hybrid agentic systems without sacrificing performance.
Key Takeaways
- Implement PrivScope to minimize data exposure.
- Analyze payloads for sensitive information.
- Maintain task success while enhancing privacy.
- Adopt task-scoped filtering techniques.
Full Summary
Hybrid local-cloud agents enhance user requests by integrating context from their persistent working state before delegating complex tasks to a cloud language model (CLM). However, this process can lead to over-disclosure, where irrelevant or sensitive information is included in the data sent to the cloud.
PrivScope was created to address this issue by implementing task-scoped disclosure control, which filters out unnecessary context and sensitive details. The methodology involves analyzing the payloads sent to the CLM and applying rules to retain only relevant information.
Results showed a significant reduction in over-disclosure incidents while maintaining high task success rates. This balance is crucial for protecting user privacy and ensuring effective task execution.
Engineers and researchers can leverage PrivScope to enhance the security of hybrid agentic systems.
