Informed consent anonymisation is the removal of the signer’s personal details from the page. It supports ICH E6(R2) good clinical practice. anonym.plus runs offline, so the agreement text stays whole while the names go.
When this applies
An auditor wants to confirm the consent wording, not who signed. The signed page holds names, dates, and a handwritten signature.
How anonym.plus handles it
- Open the signed page (PDF or scan) in anonym.plus on your device.
- Local OCR reads the printed and stamped fields on the scan.
- The tool flags the signer name, the date, and contact lines.
- Review the flags and keep the standard consent wording.
- Black out the signature block, or swap names for labels.
- Save the clean version locally with no upload.
What you need to provide
- The signed page (PDF, DOCX, or image scan).
- An operator: Redact for the signature, Replace for names.
- Optional: a label map if you track consent versions.

Limitations & cautions
A handwritten signature can be hard for OCR to read as text. The tool can black out the whole signature box to be safe. Always check the scanned page by eye, since a faint stamp or initial may sit outside the detected zone.
Frequently asked questions
Why anonymise a consent form?
Auditors and ethics boards often need to verify the wording and process, not the signer. A clean copy proves the form was correct while protecting the person who signed under GCP.
Can it handle a handwritten signature?
Yes. The Redact operator blacks out the signature block as an image area, so it does not rely on reading the handwriting as text.
Does the legal wording change?
No. Only the personal fields change. The agreement language, the study name, and the rights statements stay exactly as written.
