Globale PII Identifier Kloof: SSN, CPF, Aadhaar

Geen twee landen gebruiken hetzelfde nationale ID-systeem. SSN, Braziliaans CPF en Indiaas Aadhaar hebben elk unieke validatielogica. Hier leest u hoe globale dekking werkt.

Waarom Nationale ID's Unieke Logica Vereisen

Nationale identifiers zijn niet uitwisselbaar. Ze verschillen in:

  • Lengte: SSN is 9 cijfers; Braziliaans CPF is 11 cijfers; Indiaas Aadhaar is 12 cijfers
  • Validatiealgoritme: Elk gebruikt een andere checksum
  • Structuur: Sommige coderen persoonlijke informatie (PESEL codeert geboortedatum); andere zijn sequentieel
  • Context: Dezelfde cijfervolgorde kan een SSN in de VS en een normaal getal in Europa zijn

De Drie Grootste Nationale ID's Wereldwijd

Amerikaans SSN (330M+ burgers):

  • Formaat: XXX-XX-XXXX (9 cijfers)
  • Geen checksum vereist
  • Contextdetectie noodzakelijk (niet alle 9-cijferreeksen zijn SSN's)

Braziliaans CPF (215M+ burgers):

  • Formaat: XXX.XXX.XXX-XX (11 cijfers)
  • Twee controlecijfers met Receita Federal gewogen som
  • Fout-positief-preventie vereist beide controlecijfer-berekeningen

Indiaas Aadhaar (1,4B+ burgers):

  • Formaat: XXXX XXXX XXXX (12 cijfers)
  • Verhoeff-algoritme voor checksum
  • Eerste cijfer nooit 0 of 1

De Detectie Uitdaging

Een mondiaal e-commerceplatform verwerkt klantorders van 45 landen. In elke orderbevestiging, factuur en klantenservice-ticket kunnen nationale identifiers voorkomen.

Een tool die alleen het Amerikaanse SSN detecteert:

  • Mist Braziliaans CPF → LGPD-blootstelling
  • Mist Indiaas Aadhaar → DPDP Act-blootstelling
  • Mist Japans My Number → APPI-blootstelling

Who built this

A small team of engineers and lawyers built this.

We ship from Europe and work in the open.

Our founder note spells out why we started.

Where to start

How the parts fit

A browser add-on cleans text inside Chrome.

A Word plug-in handles drafts in Office.

A small desktop tool works on whole folders.

An agent protocol link feeds large models safely.

All four share one core engine and one rule set.

Words from our team

We started this work after a lunch about cookies.

One friend kept getting odd ads on her phone.

We asked why a court file leaked through a draft.

We sketched the first build on a napkin that week.

By month three we had a tiny demo for a friend.

She used it on her first case the next day.

Common questions we hear

Can the tool read scanned PDFs? Yes, with OCR.

Does it work on long files? Yes, in small chunks.

Can I roll my own rule set? Yes, save it as a preset.

Does it run offline? The desktop build runs offline.

Do you keep my files? No, the cloud build wipes after each run.

Will it learn from my work? No, we never train on inputs.

A short tour of the workflow

Upload a file or paste a snippet of prose.

Pick the entities you want gone from the draft.

Choose a method: replace, mask, hash, encrypt, or redact.

Press run and watch the side panel show each hit.

Skim the result and tweak any rule that misfired.

Save the cleaned file or send it to a teammate.
