Technological basis

Python, Azure AI Services, OCR, NLP, Named Entity Recognition (NER), Develappers AI framework

Our AI solution for document anonymisation automates the redaction of sensitive information in texts, scans and forms.
It recognises personal data such as names, addresses, account numbers or patient data - even in complex documents - and anonymises them in compliance with the GDPR.

The system uses modern natural language processing (NLP), OCR and rule engines to reliably differentiate between confidential and neutral content.
Whether as a cloud service on Microsoft Azure or locally in your infrastructure - you retain full control over your data.

If you want to speed up data protection processes and ensure quality at the same time: Automate your document review with AI.

AI anonymisation vs. manual verification

In many organisations, documents are still checked manually. A process that takes time and remains prone to errors.

Our AI solution automates this work: quickly, reliably and reproducibly.

Questions on the anonymisation of documents

FAQs

What does AI do when anonymising documents?

The AI automatically recognises personal data in documents and anonymises it based on rules by redacting or removing it. The entire process takes place without manual reworking and supports consistent, traceable implementation of data protection regulations.

Which document types can be anonymised?

The solution supports various document formats, including PDFs, scanned documents, Office files, emails and structured formats such as forms or tables. This makes it suitable for different specialist areas and use cases.

Is the AI solution for document anonymisation GDPR-compliant?

Yes, all processing takes place within the respective company environment. No documents or data are stored or forwarded externally. The solution therefore supports compliance with the GDPR and internal data protection guidelines.

How fast does AI work when anonymising documents?

Depending on the document type, the AI usually processes a page in less than a second. Recognition, anonymisation and logging are automated, which enables even large volumes of documents to be processed quickly.
