Identity theft is still uncommon in Brazil. Also, people are used to filling out long forms because of our national bureaucratic mindset (it&#x27;s not just the government, private enterprise is also very bureaucratic).<p>The result is that nobody blinks an eye at giving away _all_ their data. If you ask a complete stranger for his CPF (a number given by the Tax Service, a common Primary Key in many databases), they will give it to you.<p>We&#x27;re lucky that most of our criminals just aren&#x27;t very sophisticated (yet).
