Financial-account redaction is the removal of full account numbers from a court filing under the DPA 2018. anonym.plus finds each value on your device and masks it, leaving at most a short non-identifying remnant.
When this applies
Bank statements and transfer records list full numbers across exhibits. You must mask each one under the DPA 2018 before the document joins the court file.
How anonym.plus handles it
- Open the statements in anonym.plus on your device.
- Local OCR reads scanned bank and card pages.
- The tool flags bank, sort-code, and card numbers.
- Apply Mask to hide the bulk of each value.
- Confirm no full value remains in any exhibit.
- Save the clean papers locally.
What you need to provide
- The statements and exhibits (PDF, scan, DOCX).
- The Mask operator set to leave only a short remnant.
- Optional batch for many statement pages.

Limitations & cautions
A spaced or hyphenated number on a faint scan can confuse OCR. Verify the flags on image pages so no full number remains. The tool masks what it detects; check the output.
Frequently asked questions
How much of an account number should remain?
As little as needed. The DPA 2018 favours data minimisation, so anonym.plus masks the bulk of each value in one pass across the filing.
Does it catch credit-card and IBAN numbers?
Yes. Card numbers, sort codes, and IBANs are flagged along with bank values.
Can it read these numbers off a scan?
Yes. Local OCR reads the image first. Always verify faint or skewed pages.
