Clinical Letter Batch Anonymization with anonym.plus

Healthcare Solution · Clinical Documentation · HIPAA Safe Harbor (45 CFR §164.514(b))

Batch anonymization is the removal of PHI from a whole folder of letters in one run. It applies HIPAA Safe Harbor (45 CFR §164.514(b)) the same way across every file. anonym.plus works on your device, with a shared label map so one patient maps to one alias everywhere.

When this applies

A teaching corpus or research set means cleaning hundreds of letters at once, with the same patient or doctor in many. One-by-one work risks drift. A batch run keeps it even.

How anonym.plus handles it

1. Point anonym.plus at the folder on your machine.
2. It scans each letter for the full Safe Harbor ID set.
3. A shared map keeps repeat people steady across the run.
4. Review the summary and fix any low-confidence flags.
5. Save the clean corpus on your device.

What you need to provide

• A folder of letters (PDF, DOCX, or mixed).
• The shared label map turned on for steady results.
• An operator (Replace works well for a corpus).

PHI entity types detected

Compliance achieved

• Applies HIPAA Safe Harbor (45 CFR §164.514(b)) the same way to all files.
• The shared map keeps results steady across the run.
• Whole-folder work stays offline — nothing uploaded.

Limitations & cautions

Mixed folders (some scanned, some native) lean on OCR for the image files, so review low-confidence flags from scans. A shared map keeps results even, but you must guard that map, since it can re-link the set if kept.
