So again, relatively explicit identity claims to the data that is captured by your smartphone. So GPS records, where do you go? Your credit card, what do you buy? And the same way that we could put the pieces together from someone's bedroom, we can also do that in someone's digital space.

Yeah, it's actually one of my favorite studies that was coming out of MIT. And what they showed is that it's very easy to identify someone based on your spending records or your GPS records. So you can imagine, as you said, there's millions of people in New York.

And even if we, say, got access to all of their credit card spending, anonymized it so we don't have names, we don't have any personal identifiers, it's very easy to reverse engineer the data. You can imagine that, let's say, you

go and get a matcha latte at Starbucks on 72nd Street in New York at 7.20 a.m., then you have lunch in a certain place, and maybe you take a cab downtown at night, there's at some point only so many people who have exactly that same signature. So you can almost think of it as a fingerprint that is made up of your data.

Yeah, so that's in a way that the most interesting part of this entire field of research is like, yeah, we can identify you as a person, we can know that it's Shankar based on your data. But for me, the more interesting part is actually that we can dive into your psychology. So we can take a look at what's going on inside your mind.

And so the study that we did when we try to predict someone's income was essentially relying on their Facebook data. So what is it that people talk about and post on social media? And I think there were some really interesting, sometimes quite uncomfortable truth that we discovered.

But overall, the bottom line was that just by looking at what you talk about on Facebook, we can have a pretty good sense of your socioeconomic status.
