Comment on Norwegian government to set 15-year age limit for using social media

  As far as I understand, BankID actually abstracts away those numbers. FB have to use an API, and more or less receive a true or false on their query.

  They recently opened up for using BankID to prove your age at bars and such, and I think they only get to know if person is old enough or not. Not even a number, just old enough.

    This is the right way to protect privacy. Auditable government departments have your data anyways. They don’t provide the data to companies, but they answer questions like “old enough to drink?” With yes no answers.

      The government can keep a log of what sites asked for such a proof though, and better assume they do.

        That’s true, but the government is auditable by citizens though. We can legislate them to not keep logs and most importantly we can see if they’re sharing data with advertisers.

    If truly masked, it might be fine. But the site has to gather that data in order to append it to the API call and it, therefore, mean that they could keep it (even of they actually may not). There are ways around it, such as with session tokens passed between the social media’s page and the bank’s official API page. But, knowing fb, they won’t use the latter.

      Obviously not, it’s like Google authentication , you log into a site, doesn’t mean the site can see your Gmail.

        It depends how it’s implemented. If they implement correctly, then you’re right. But not all do. That’s a fact that bit me in the arse once, and I no longer use those features for lack of trust.
