Benefits file batch redaction is the removal of personal data from a whole folder of scheme files in one run, in line with the duty to protect member data under the Pensions Act 2004 and the Pension Schemes Act 1993. anonym.plus processes up to 20 at a time on your device, with a shared map so one worker maps to one alias everywhere.
When this applies
A scheme folder holds enrolment forms, statements, and nominations naming the same people. One-by-one work risks drift, so a batch run cleans the set evenly.
How anonym.plus handles it
- Point anonym.plus at the scheme folder on your machine.
- It scans each file for names, NI numbers, and account data.
- Local OCR reads any scanned pages in the set.
- A shared map keeps repeat workers steady across files.
- Review the summary and fix low-confidence flags.
- Save the clean set locally.
What you need to provide
- A folder of benefits files (PDF, DOCX, CSV, mixed).
- The shared label map turned on for steady results.
- An operator (Replace works well for a scheme folder).

Limitations & cautions
A mixed folder of scans and native files leans on OCR for the images, so review low-confidence flags. The shared map can re-link the set if kept; turn it off when you need true anonymity under UK GDPR Recital 26.
Frequently asked questions
How does batch mode keep one worker steady?
A shared map logs each person once, so the same worker maps to the same alias in every file across the folder.
How many files can one run handle?
Up to 20 files per batch, all processed locally with OCR for any scanned pages.
Does batch work upload anything?
No. The whole run is offline, so scheme data stays on your machine.
