USE CASES
Where hospitals use Datenmaske
Anonymize patient records
Patient records contain specially protected health data. Datenmaske suggests names, addresses, dates of birth and other personal data for your review.
Prepare medical letters
Prepare medical letters for sharing with third parties, research institutions or second opinions. Datenmaske automatically removes all personal data while preserving the medical content.
Art. 9 DSGVO — Protect health data
Health data belongs to the special categories of personal data and is subject to stricter requirements. Datenmaske ensures that this data is redacted reliably and irreversibly.
Provide research data
For clinical trials and medical research, data must be prepared in a risk-appropriate manner. Datenmaske assists with redaction; a legal classification as anonymization or pseudonymization remains necessary.
Redact discharge reports
Discharge reports contain detailed patient data. Datenmaske automatically prepares these documents for anonymized sharing — for quality assurance, research or second opinions.
Invoices and billing data
Medical invoices and billing documents contain patient data and insurance information. Datenmaske automatically detects and redacts names, IBANs and insurance numbers.

FAQ
Frequently asked questions
How does Datenmaske handle health data under Art. 9 DSGVO?
Health data belongs to the special categories of personal data under Art. 9 DSGVO and is subject to stricter requirements. Datenmaske detects and redacts patient data irreversibly, so that — provided all suggestions are correctly confirmed — the remaining documents no longer contain any known health data.
Can Datenmaske be used for medical research?
Yes. For research projects, patient records and medical letters must be anonymized before being transmitted to research institutions. Datenmaske automates this process and ensures that all personal data is reliably removed.
Which data types are detected in medical letters?
Datenmaske automatically detects patient names, addresses, dates of birth, insurance numbers, phone numbers, email addresses, IBANs and other personal data. Detection is based on regular expressions and AI-powered Named Entity Recognition.
Is the redaction irreversible?
Yes. Datenmaske permanently removes the text content from the PDF. The redacted data cannot be restored after export. This meets the requirements for effective anonymization, also for sensitive health data.
Are documents processed on German servers?
Datenmaske Web supports GDPR-compliant processes with a DPA, TLS transmission and primary hosting in Germany. The published TOMs do not cover professional secrets protected under § 203 StGB. For such content, Datenmaske Secure with local processing is intended for early access. The responsible party must review the specific use in advance.
