Batch redaction is the removal of PII from a whole folder of deals in one run. Scale changes the legal picture: Art. 35 calls for a data-protection impact assessment where processing is likely to be high risk. Art. 32 then sets the security bar for the shared label map. A batch handles up to 20 files.
When this applies
A precedent library or audit means cleaning many deals at once. Once the set is large, Art. 35 puts an impact assessment on the table, and the shared map becomes the most sensitive artefact you hold. A local run keeps both under your control.
How anonym.plus handles it
- Point anonym.plus at the folder on your machine.
- It scans each file for the full PII set.
- A shared map keeps repeat parties steady across the run.
- Review the summary and fix any low-confidence flags.
- Swap or black out the confirmed IDs.
- Save the clean library on your device.
What you need to provide
- A folder of deals (PDF, DOCX, or mixed; up to 20 files).
- The shared label map turned on for steady results.
- An operator (Replace works well for a library).
PII entity types detected
| Category | anonym.plus entity type | Example |

| Parties | ORGANIZATION | party across files → [PARTY_1] |
| Names | PERSON | repeat signatory → [SIGNATORY_1] |
| Dates | DATE_TIME | deal dates → [DATE] |

Compliance achieved
- Supports a GDPR Art. 35 impact assessment by cutting personal data at source.
- Guards the shared label map to the Art. 32 standard with AES-256-GCM.
- A map that can re-link the set makes it pseudonymous under Art. 4(5).
- Whole-folder work stays offline — nothing uploaded.

Limitations & cautions
A batch handles up to 20 files at a time, so split a large library into runs. Mixed folders lean on OCR for scans, so review low-confidence flags. Guard the shared map, since it can re-link the set if kept.
Frequently asked questions
When does a bulk run need an impact assessment?
Art. 35 turns on likely high risk, and scale is one of the markers regulators weigh. A library-wide run over contract data is worth assessing before you start.
How does batch mode keep one party steady?
A shared map logs each party once, so the same firm or signatory maps to one alias in every file across the folder.
How many files can one batch take?
Up to 20 at a time. Split a larger library into several runs. Each run keeps its own steady labels across the files.
