Dialing Privacy and Utility: A Proposed Data-Sharing Framework to Advance Internet Research

The current reluctance to share systems and network data derives from gaps in the law, commercial pressures, and evolving considerations of threat models and ethical behavior. Internet research stakeholders have an opportunity to tip the risk scales in favor of more protected data sharing by proactively implementing appropriate privacy risk management. The privacy-sensitive sharing (PS2) framework integrates privacy-enhancing technologies with a policy framework. The authors evaluate this framework along two primary criteria: how well the policies and techniques address privacy risks, and how well policies and techniques achieve utility objectives. A case study applies the framework to enable network operational data sharing for cybersecurity RD.
