No Silver Bullet, But a Silver Lining? PETs and International Data Transfers
Is there a role for Privacy Enhancing Technologies (PETs) to play in the context of international data transfers? The answer to this question could be one of the keys to unlock trusted cross-border data flows at scale in the age of AI.
This was the topic explored in a session organized by the Future of Privacy Forum (FPF) during the Global CBPR Forum in Lima, Peru. Bringing together technical, regulatory, policy, and academic perspectives, the session provided an in-depth overview of initiatives centering on PETs in data transfer developments. It included a technical presentation of two of the most promising such technologies available – trusted execution environments and differential privacy, as well as a recent use case from a US-UK policy pilot and a regional perspective on PETs adoption in Latin America.
The session highlighted both the growing maturity of PETs deployments, as well as the structural challenges that continue to shape their adoption. A central takeaway was that PETs are increasingly being positioned as enabling tools for data use and collaboration — particularly in contexts where legal, regulatory, or trust constraints have historically limited data sharing. By illustrating a specific medical use case and their technical features, speakers demonstrated how PETs can support more responsible data ecosystems and trusted data sharing.
