Branch transaction log redaction takes personal data out of a daily counter record. UK GDPR and the DPA 2018 limit how a bank shares holder information. anonym.plus marks each row on your machine, so the activity pattern stays readable while customer data is shielded.
When this applies
Such a register lists each customer, account, and amount across a day in a Glasgow branch. You must hide those before the file goes to an analyst.
How anonym.plus handles it
- Open the register in anonym.plus on your device.
- Local OCR reads any imaged pages.
- It flags customers, accounts, and amounts.
- Confirm the flags and keep the cashier and time codes.
- Apply Mask across the customer and account columns.
- Save the clean record locally.
What you need to provide
- The counter register (CSV, PDF, or scan).
- An operator: Replace, Redact, or Mask.
- Optional batch for several days at once.

Limitations & cautions
A rare amount at a known time can re-identify a customer even with names masked. Consider grouping or rounding amounts when the file is for analysis rather than reconciliation.
Frequently asked questions
Can the tool mask a whole column?
Yes. For a CSV or tabular file, it flags every value in the customer and account columns so you can mask them together.
Will cashier and time codes survive?
Yes. Allow-list those operational codes so the activity pattern stays for analysis.
Is the file uploaded for processing?
No. The app is fully offline, so the record stays on your device.
