Meta has developed Privacy Aware Infrastructure (PAI) and Policy Zones to ensure that data usage adheres to specified purposes, particularly in extensive batch processing environments. Policy Zones work in conjunction with Meta’s data warehouse and processing systems, utilizing runtime enforcement and SQL parsing to manage data access and usage effectively. This initiative is part of Meta’s broader commitment to privacy and data protection.
