Telematics anonymisation is the removal of direct identifiers from driving data. UK GDPR Recital 26 says truly anonymous data falls outside the rules, and the ICO Anonymisation Code applies a motivated-intruder test. anonym.plus marks each identifier on your device, so the patterns stay analysable while the person stays shielded.
When this applies
A driving log ties each trip to a named motorist and start address. You strip those identifiers before the data feeds a pricing model.
How anonym.plus handles it
- Open the log in anonym.plus on your device.
- The tool flags names, IDs, and addresses.
- Local OCR reads any scanned trip summary.
- Turn the alias map OFF for true anonymity.
- Swap or black out the confirmed identifiers.
- Save the clean log locally.
What you need to provide
- The driving log (CSV exported to PDF, DOCX, TXT).
- An operator (Redact suits a trip table).
- The alias map turned OFF so no link survives.

Limitations & cautions
Recital 26 treats data as anonymous only if no one can re-identify a person. A regular home-to-work trace can still single someone out. Coarsen the start point and times before you publish.
Frequently asked questions
Why are trip traces hard to anonymise?
A repeated home-to-work pattern can re-identify a person even with the name gone. Coarsen the start point and times to meet the Recital 26 standard.
Why turn off the alias map?
An alias map can re-link a trace to a person. For true anonymity under Recital 26, leave it off so no reverse path remains.
Is the log uploaded?
No. The app runs locally, so the data never leaves your device.
