Automated anonymization of sensitive research data

Purpose

1. Automate the anonymization of sensitive research data by masking, removing, or generalizing personal identifiers from raw datasets used in scientific foundations.

2. Enables compliance with privacy laws (GDPR, HIPAA), facilitates safe data sharing, and preserves scientific value in non-profit research.

3. Automatedly reduces manual workload, ensures uniformity, minimizes human error, and speeds up analytical readiness.

Trigger Conditions

1. New dataset ingested to data lake or local server.

2. Manual upload flagged as containing PII.

3. Scheduled job (e.g., nightly batch process).

4. Request from authorized data access portal or API.

5. Change in data structure or metadata indicating new fields with sensitive content.
