This paper presents Autononym, an AI-powered software platform capable of robustly and scalably anonymizing health data across several formats, including unstructured free-text documents, tabular datasets, and medical images in both DICOM and standard RGB formats.

Executive Summary

This research paper examines a critical privacy challenge related to LINKABILITY — the ability to connect two pieces of information to the same person.

anonymize.solutions addresses this through dual-layer detection (210+ regex + 3 NLP engines) identifying 260+ entity types across 48 languages, with 5 anonymization methods that break the linkability chain.

Root Cause: SD1 — LINKABILITY

The ability to connect two pieces of information to the same person. This is the foundational operation that makes PII dangerous. Nearly every pain point is an expression of linkability being created, exploited, or failing to be broken.

Irreducible truth: You cannot have useful data that is completely unlinkable AND completely useful. The very features that make data informative make it linkable. This is not a bug — it is information theory. The information content of a dataset and its linkability are the same property measured differently.

The Solution: How anonymize.solutions Addresses This

Detection Capabilities

anonymize.solutions identifies 260+ entity types including zip codes, dates of birth, gender markers, demographic quasi-identifiers. The dual-layer (regex + NLP) architecture uses 210+ custom pattern recognizers (246 patterns, 75+ country formats, checksum-validated) for structured identifiers and spaCy (25 languages) + Stanza (7 languages) + XLM-RoBERTa (16 languages) for contextual references.

Anonymization Methods

Hash is recommended for this pain point: deterministic SHA-256 hashing enables referential integrity across datasets while preventing re-identification from original values. Replace provides an alternative — substituting quasi-identifiers with type labels removes re-identification potential while preserving data structure. For scenarios requiring reversibility, Encrypt (AES-256-GCM) enables authorized recovery of original values.

Architecture & Deployment

The REST API integrates into data pipelines (n8n, Make, Zapier) for automated PII anonymization before data reaches downstream systems. Three deployment models — SaaS (token pay-per-use), Managed Private (customer key management), and Self-Managed (Docker, air-gapped) — match any infrastructure requirement.

Compliance Mapping

This pain point intersects with GDPR Recital 26 identifiability test, Article 89 research safeguards.

anonymize.solutions’s GDPR, HIPAA, FERPA, PCI-DSS, ISO 27001 compliance coverage, combined with 100% EU (Hetzner Germany, ISO 27001) hosting, provides documented technical measures organizations can reference in their compliance documentation and regulatory submissions.
