Lending file batch redaction is the removal of personal data from a whole folder in one run. UK GDPR Art. 5(1)(e) requires personal data to be kept no longer, and held no more openly, than the purpose needs, and that duty applies file by file across a whole book of business. anonym.plus processes up to 20 at a time on your device, with a shared map so one applicant maps to one alias everywhere.
When this applies
A book of business holds many files that name the same applicants, each subject to the same Art. 5(1)(e) storage-limitation duty. One-by-one work risks drift, so a batch run applies the rules evenly across the set, and the ICO's motivated-intruder test still governs what counts as truly anonymous once you finish.
How anonym.plus handles it
- Point anonym.plus at the folder on your machine.
- It scans each file for the personal data UK GDPR covers.
- Local OCR reads any scanned pages in the set.
- A shared map keeps repeat applicants steady across files.
- Review the summary and fix low-confidence flags.
- Save the clean set locally.
What you need to provide
- A folder of finance files (PDF, DOCX, mixed).
- The shared label map turned on for steady results.
- An operator (Replace works well for a book of business).

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 the ICO's motivated-intruder standard.
Frequently asked questions
How does batch mode keep one applicant steady?
A shared map logs each person once, so the same applicant 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 customer data stays on your machine. Turn the map off for true anonymity, since UK GDPR Art. 5(1)(e) and the ICO's motivated-intruder test both look at whether a result can genuinely no longer identify anyone.
