HIPAA-Compliant Secure Patient Data Anonymization Pipeline

Design a robust data anonymization framework that can process complex medical records while maintaining HIPAA compliance. The solution must dynamically redact personally identifiable information (PII), generate cryptographically secure patient tokens, and support multiple data input formats including HL7, FHIR, and CSV. Implement differential privacy techniques to ensure no individual patient can be re-identified through statistical inference. Include comprehensive logging, encryption at rest and in transit, and a modular architecture that allows easy extension for future privacy regulations.
