Sex, birthday, and zip code is totally different than sex and birth year… sex, birthday, and zip code creates 1,523,000,000 different ‘buckets’ of people for everyone born in the last 50 years. That is more buckets than people in the US, so it makes sense that you could deanonymize.
Sex and birth year only creates 100 total buckets for people born in the last 50 years. There is no way you could deanonymize that.
- labawi 5y agoCorrect on the differences. True, it cannot be deanonymized if that is the only data you have. However, if you have any other data, even if it is not PII by itself and doesn't even look interesting, there is no way to guarantee it won't be personally identifiable when combined. As has been said, I don't think there is a way to anonymize data, that is useful and not reversible when combined with other data. Even if you only have 2 buckets.
