全球个人信息标识:SSN、CPF、Aadhaar及更多

以美国为中心的个人信息工具局限

大多数个人信息工具诞生于美国,专为美国数据格式而设计。美国社会安全号码(SSN)由九位数字构成,格式为AAA-BB-CCCC,其地区码、组号和序列号均遵循有据可查的规则。以美国为主的工具能够准确检测SSN,也能识别美国电话号码、电子邮件地址和驾驶证。但凡涉及美国以外的国家身份标识,这些工具便无能为力。

GDPR并不允许「仅限美国格式」的豁免。以德国税务识别号(Steuer-ID)为例:这是一个11位数字的税务标识,由联邦中央税务局签发,末位为校验位,能够唯一标识德国居民,正如SSN唯一标识美国公民一样。GDPR第4条涵盖「与已识别或可识别自然人相关的任何信息」,Steuer-ID完全符合这一定义,属于个人数据,无论您的工具是否能够识别该格式。

在使用仅支持美国格式工具的系统中,因遗漏欧盟特有个人信息而导致的GDPR罚款已有先例。合规漏洞真实存在,执法行动已然发生。相关背景请参阅我们的GDPR合规指南

欧洲标识体系全景

覆盖缺口相当可观,以下按国家逐一列举。

德国: Steuer-ID——11位数字,经校验位验证。社会保险号(Sozialversicherungsnummer)——12个字段,结构化格式。护照号(Reisepass)——含机构代码的10位字符。

法国: NIR是国家社会保障号,共15位数字,分别编码性别、出生年份、出生月份、出生省份、市镇代码及校验密钥。SIRET含14位数字,SIREN含9位数字。

瑞典: 个人号码(Personnummer)格式为YYMMDD-XXXX。协调号码(Samordningsnummer)用于非居民,日期值偏移60。

挪威: 出生号码(Fødselsnummer)格式为DDMMYYNNNKK共11位,中间组编码性别。D号(D-nummer)的日期值偏移40。

巴西: CPF(Cadastro de Pessoas Físicas)含11位数字及两个校验位。CNPJ为14位企业标识。

印度: Aadhaar是12位生物特征识别号,采用Verhoeff校验算法。PAN是含字母和数字的10位税务标识。

阿联酋: 酋长国身份证号含15位数字,格式为784-出生年份-序列号-校验位。

一支覆盖12个国家的全球人力资源团队只需要一个工具,能够在单次扫描中处理所有12种国家身份标识格式——为每个国家维护独立的正则表达式库根本行不通。

285+实体类型架构

285+实体类型库涵盖所有欧盟成员国格式,以及亚太地区主要证件标识,包括Aadhaar、PAN、CPF、CNPJ、酋长国身份证和泰国公民身份证。美国格式(SSN、EIN、各州驾驶证)同样包含其中。一个引擎统一处理所有格式,数据库随格式变化持续更新。

这正是大多数工具留下的缺口。欢迎查阅实体参考文档了解完整覆盖范围,或访问定价页面了解按量计费方案。

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.
