Anonymization Pipeline

Overview​

DocuDesk provides a 4-step document anonymization pipeline for GDPR-compliant processing. Files are uploaded to a per-user DocuDesk folder, analyzed for personally identifiable information (PII), and anonymized by replacing detected entities with placeholders. All processing runs 100% locally.

Pipeline Steps​

  1. Upload: Drag-and-drop or select a file to upload to your DocuDesk/ folder
  2. Analyze: Extract text and detect entities (persons, organizations, locations, etc.)
  3. Anonymize: Review detected entities and anonymize the document
  4. Done: Download the anonymized document
