Evaluating cancer prevention programs requires collecting and linking data on a case specific level from multiple sources of the healthcare system. Therefore, one has to comply with data protection regulations which are restrictive in Germany and will likely become stricter in Europe in general.
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.
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.
anonymize.solutions identifies 260+ entity types including names, addresses, financial records, purchase history, app usage data, credit information. 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.
Redact is recommended for this pain point: removing identifiers before data leaves organizational boundaries prevents contribution to cross-source aggregation profiles. Hash provides an alternative — hashing identifiers enables internal analytics while preventing external parties from matching records. For scenarios requiring reversibility, Encrypt (AES-256-GCM) enables authorized recovery of original values.
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.
This pain point intersects with GDPR Article 5(1)(b) purpose limitation, Article 5(1)(c) minimization, CCPA opt-out rights.
