Approaches and Challenges to Purpose Limitation across Diverse Data Uses
summary
Meta describes a working system that uses annotations and lineage to label assets, traverse data flows, and apply policy checks; engineers run code inside policy zones so infra enforces or blocks disallowed flows and supports reclassification when transforms anonymize data. The stack runs at scale across millions of assets, 3 billion daily users and 50,000 employees, protects hundreds of requirements, provides continuous monitoring, and reports that enforcement and iterative remediation meaningfully reduce violations.
