Endoscopy de-identification is the removal of patient identifiers from the file. UK GDPR Art. 9 and the DPA 2018 govern health data. anonym.plus runs it on your device. The procedure findings stay, but no person is named.
When this applies
A colonoscopy case suits a training deck. The findings and photos can stay, yet the name, the dates, and the captured banner have to be hidden first.
How anonym.plus handles it
- Open the file (PDF, image, or scan) on your machine.
- Local OCR reads any text printed on the capture.
- The tool flags names, dates, IDs, and the banner line.
- Review each flag and keep the procedure findings.
- Swap each ID for a token, or box it out.
- Save the clean study. The source stays with you.
What you need to provide
- The file (PDF, JPEG, PNG, or image scan).
- An operator: Replace (swap), Redact (remove), or Mask (partial).
- Optional: a name map for repeat procedures.

Limitations & cautions
Captured photos may carry a banner with the name. OCR reads most of it. Check each photo before release, since a missed banner undoes the rest.
Frequently asked questions
Do the captured photos get checked too?
Yes. Local OCR reads any banner on each photo. You box the text so the anatomy stays visible while the name goes.
Will the findings narrative stay intact?
Yes. Clinical wording is left alone. Only patient details change, so the procedure notes read as the doctor wrote them.
Can I process the write-up and the photos together?
Yes. Add the text file and the photos to one folder. The app applies your rules across the whole case in one pass.
