Data Clean Room
A data clean room is a secure environment where multiple parties can share and analyze combined datasets without exposing raw personal data to each other. It enables collaborative measurement and audience insights while preserving user privacy.
Examples
A retailer and a media company use a data clean room to measure ad campaign lift against purchase data without sharing individual customer records.
Best Practices
Define clear governance rules before sharing data, limit queries to aggregate-level outputs, and ensure differential privacy mechanisms are in place.
