targeting legal, healthcare, and financial services organizations with large paper archive scans.
The Challenge
Organizations with legacy document archives frequently encounter image-based PDFs — documents scanned from paper without OCR text layer creation. A scanned contract stored as a PDF image has no searchable or selectable text; to a standard PII tool, it's invisible. Organizations with large scanned document archives (legal firms, healthcare providers, government agencies, banks) face a complete gap in their anonymization coverage for historical documents. GDPR's right to erasure (Article 17) applies to personal data "regardless of the format in which it is stored" — the fact that data is in an image format doesn't exempt it from GDPR obligations.
By the Numbers
- GDPR's right to erasure (Article 17) applies to personal data "regardless of the format in which it is stored" — the fact that data is in an image format doesn't exempt it from GDPR obligations.
Real-World Scenario
A law firm undertaking a GDPR data audit discovers 80,000 image-based PDF client contracts scanned between 1998-2010. Standard PII tools return zero detections. Using anonym.legal's text-in-image processing, the firm processes the archive in batches of 5,000. OCR extracts text from each image-PDF, NLP detects client names, addresses, ID numbers, and financial references, and the anonymized text output enables the firm to fulfill right-to-erasure requests for the historical archive. Previously impossible compliance obligation fulfilled.
Technical Approach
The text-in-image detection feature integrates OCR with NLP in a single processing pipeline. Image-based PDFs and image files (PNG, JPG) containing scanned text are processed through OCR to extract text, then through the full 260+ entity NLP pipeline for PII detection. The anonymized output is the extracted text with PII replaced, redacted, or encrypted. Batch processing handles large legacy document archives.
