HIPAA-Compliant Patient Data Anonymization Pipeline

Design a Laravel-based data anonymization pipeline that automatically processes patient records while maintaining HIPAA compliance. Create a robust system that can handle PHI (Protected Health Information) by implementing one-way hash transformations for sensitive fields like names, social security numbers, and contact details. The pipeline should support batch processing, generate comprehensive audit logs, and include configurable anonymization rules that can be adjusted based on specific healthcare regulatory requirements.
