In-depth articles from the anonym.plus team on document privacy, data anonymization, and regulatory compliance. All guides are written for practitioners — data protection officers, compliance teams, legal counsel, and developers implementing privacy-first workflows.
Topics span the GDPR (Regulation (EU) 2016/679) and the EU AI Act (Regulation (EU) 2024/1689), HIPAA (1996), on-device detection of 340+ PII entity types, the practical difference between anonymisation and pseudonymisation (Art. 4(5), Recital 26), and step-by-step workflows for redacting documents before they reach an LLM. Every article is grounded in the primary legal source it cites, and new guides are added as regulations and tooling evolve.
