Hi, I'm Julian. So I was asked to do this because apparently I'm funny and since I work

in London I get told a lot that Germans aren't funny so I'm going to do this in English.

Right, so this talk is about GDPR, die Datenschutzgrundverordnung and location based game I play. I think some

of you have seen me or heard me talk about Ingress. That's a location based game by the

same company that has done Pokemon Go. Well, they've done it after Ingress. And essentially

it's an augmented reality game where you walk around in the real world. You are the player

and it's very much about exploration and about social stuff. You meet lots of people. It's

not unlike the park community really. And I kind of see it as the art of taking detours.

Like wherever I go I play and then I wander around and get lost. But I'm not really lost

because I'm seeing stuff. And it's really good for your health. And it's kind of like

a fun game. I've been playing it for over seven years now. But, you know, there's a

lot of data that they collect. When they started out they were part of Google. Now they're

separate and they've got three games now. Ingress, Pokemon Go and Harry Potter. And

they've just announced something really weird, something else that I forgot what it is. But

it's a... So they collect a lot of data. And, you know, GDPR requests we could do that.

You know, we can ask them what kind of data do they have about me. We could technically

also ask them to delete it. But yeah, why would I do that? That's kind of stupid. Because

I want them to have that data, right? Because the game's for free. So apparently I'm the

product. So I don't really have a choice. All right. So what I can do is I can send

a right of access request which is a very generic letter. Dear Sir, Madam, I'd like

to give you my data. I'd like you to give me my data because you have to. This is my

account. Thanks. So I've done that. And then, like a month later, I got a zip archive. Well,

I got an email that had a link and another email that had a password. And behind that

link there was this archive full of mostly CSV files. So there are loads of them. Some

of them contain current information. I've got my current situation in the game at the

time when they took the snapshot. So that's fairly useless. And then there's stuff about

my user profile that's fairly useless as well. But then there are small subsets that are

kind of good. And this one is really fun. So this is about two years ago. What it does

is it's like almost 50 megabytes of plain text game lock, tap separated values. It's

really fun. So if we could take a look at it, this is just a really small thing. It

goes back to 2017 somewhere, I think, given the coordinates that should be in Berlin where

I did stuff. So I fired some weapons in the game. I walked around. I went somewhere else.

I hacked a portal. I did stuff. So what they gave me was 2015 in September to 2018 in August

when I requested it, which is almost four years, but it's not my entire history. So

they didn't give me all of it, which is a bit of a shame, but it's quite nice. So what

can we do with this? In general, we can see what cities or countries we visited. We can,

for example, see where am I a lot? Like I always interact with this one point of interest

on the map. Probably I live there. Hmm. Right. Or work there. I can compare this with my

Google location history that I've got on, obviously, because I want to know where I've

gone. And compared to Max, for example, who looks really horrified right now, I don't

really care what Google knows about me because I don't really have a choice anyway. So yeah,

you can also see people's daily routines in this. But then you can do stuff that's relevant

to the game, like what's my favorite portal or understand where all my game experience

points came from, maybe understand how long it's going to take for me to achieve a certain

metal or what kind of portals or points of interest I've submitted. So we could, of course,

roll our own. Like we could use SQLite, dump this in, write some Perl, do some geocoding.

It's all easy. It's all fun. I've done some of that. But then other people have already

done the work. So there are a couple of different projects. We don't really have to go into

them. They're all over the place in terms of what kind of technologies they've used.

Yeah, there are a few useful ones. So let's take a look at this. This is Cluj-Napoca in
