Meta has developed Privacy Aware Infrastructure (PAI) and Policy Zones to enforce purpose limitations on data, particularly in large-scale batch processing systems. This initiative integrates with Meta’s extensive data warehouse and processing systems, utilizing runtime enforcement and SQL parsing to ensure compliance with privacy standards. The implementation of these measures is significant for maintaining user trust and adhering to regulatory requirements.
