Transitive Data Privacy: Behind Golden State Killer DNA and Cambridge Analytica

What you don’t share can still hurt you

We are spending a lot of time discussing what happens to data when you explicitly or implicitly share it. But what about data that you have never ever shared?

Your Cousin’s DNA

In short, if you have never taken a DNA test but one or more of your blood relatives has, and shared that data — some of your DNA is effectively now available for a match.

While this may have seemed like theory a few weeks ago, the cops caught the Golden State Killer by using this method.

Cambridge Analytica

The number of users that took the quiz was shockingly small — only 300,000 users participated. And yet, upwards of 50 million (as many as 87 million) people eventually had their data collected by Cambridge Analytica.

And all of this was done legally and while complying with the platform requirements at that time.

Transitive Data Privacy

As private citizens, and corporations, we now have to think about transitive data privacy loss.
