    All this from @SteveBellovin! Furthermore, the existence of this “Database of Ruin” — a panopticon that merges every available source of data about every individual — would lead to far more false positives, and far more confidence in those false positives.

    Data quality is always a problem. Overconfidence is data is always a problem. A data panopticon multiplies both those problems. The Database of Ruin doesn’t just connect individuals to closely guarded secrets; it will inevitably •create• completely false secrets out of thin air, at scale. https://infosec.exchange/@SteveBellovin/114308854802931253

      Worth noting: combining different databases is generally regarded as the single most dangerous thing to do from a privacy perspective. Here's what Paul Ohm wrote a few years ago (https://hbr.org/2012/08/dont-build-a-database-of-ruin): In my work, I’ve argued that these databases will grow to connect every individual to at least one closely guarded secret. This might be a secret about a medical condition, family history, or personal preference. It is a secret that, if revealed, would cause more than embarrassment or shame; it would lead to serious, concrete, devastating harm. And these companies are combining their data stores, which will give rise to a single, massive database. I call this the Database of Ruin. https://flipboard.com/@newyorktimes/the-upshot-imovb8bqz/-/a-pvsZrW8uTLKxDaAmALYvXw%3Aa%3A3195393-%2F0
