Introducing Martin Dittus, Data Scientist and Darknet Researcher

Martin Dittus is a Data Scientist at the Oxford Internet Institute. The stringent ethics process governing his research means he currently can’t even contact anyone on the marketplace.

We’re sitting upstairs, hunched over a computer, and Martin is showing me the darknet. I guess I have as good an idea as most people what the darknet is, i.e. not much. We’re looking at the page of someone claiming to be in the UK who’s selling “locally produced” cannabis, and Martin is wondering if there’s any way of telling if it’s blood cannabis. How would you go about determining this? Much of what is sold on these markets is illegal, and can lead to prosecution, as with any market for illegal products. But we’re not buying anything, just looking. The stringent ethics process governing his research means he currently can’t even contact anyone on the marketplace. [Read more: Exploring the Darknet in Five Easy Questions] Martin Dittus is a Data Scientist at the Oxford Internet Institute, and I’ve come to his office to find out about the OII’s investigation (undertaken with Mark Graham and Joss Wright) of the economic geographies of illegal economic activities in anonymous Internet marketplaces, or more simply: “mapping the darknet.” Basically: what’s being sold, by whom, from where, to where, and what’s the overall value? Between 2011 and 2013, the Silk Road marketplace attracted hundreds of millions of dollars worth of bitcoin-based transactions before being closed down by the FBI, but relatively little is known about the geography of this global trade. The darknet throws up lots of interesting research topics: around traffic in illegal wildlife products, the effect of healthcare policies on demand for illegal prescription drugs, whether law enforcement has (or can have) much of an impact, questions around the geographies of trade (e.g. sites of production and consumption), and the economics of these marketplaces—as well as the ethics of researching all this. OII researchers tend to come from very different disciplinary backgrounds, and I’m always curious about what brings people here. A computer scientist by training, Martin first worked as a software developer…

Exploring the Darknet in Five Easy Questions

We caught up with Martin Dittus to find out some basics about darknet markets, and why they’re interesting to study.

Darknet marketplaces are typically set up to engage in the trading of illicit products and services, and are considered criminal in most jurisdictions. Image: Dennis Yip (Flickr).

Many people are probably aware of something called “the darknet” (also sometimes called the “dark web”) or might have a vague notion of what it might be. However, many probably don’t know much about the global flows of drugs, weapons, and other illicit items traded on darknet marketplaces like AlphaBay and Hansa, the two large marketplaces that were recently shut down by the FBI, DEA and Dutch National Police. We caught up with Martin Dittus, a data scientist working with Mark Graham and Joss Wright on the OII’s darknet mapping project, to find out some basics about darknet markets, and why they’re interesting to study. Firstly: what actually is the darknet? Martin: The darknet is simply a part of the Internet you access using anonymising technology, so you can visit websites without being easily observed. This allows you to provide (or access) services online that can’t be tracked easily by your ISP or law enforcement. There are actually many ways in which you can visit the darknet, and it’s not technically hard. The most popular anonymising technology is probably Tor. The Tor browser functions just like Chrome, Internet Explorer or Firefox: it’s a piece of software you install on your machine to then open websites. It might be a bit of a challenge to know which websites you can then visit (you won’t find them on Google), but there are darknet search engines, and community platforms that talk about it. The term ‘darknet’ is perhaps a little bit misleading, in that a lot of these activities are not as hidden as you might think: it’s inconvenient to access, and it’s anonymising, but it’s not completely hidden from the public eye. Once you’re using Tor, you can see any information displayed on darknet websites, just like you would on the regular internet. It is also important to state that this anonymisation technology is entirely legal. I would personally even argue that such…

How useful are volunteer crisis-mappers in a humanitarian crisis?

by David Sutcliffe 18/05/2017

Concerns have been raised about the quality of amateur mapping and data efforts, and the uses to which they are put.

Haitians set up impromtu tent cities thorough the capital after an earthquake measuring 7 plus on the Richter scale rocked Port au Prince Haiti just before 5 pm yesterday, January 12, 2009.

User-generated content can provide a useful source of information during humanitarian crises like armed conflict or natural disasters. With the rise of interactive websites, social media, and online mapping tools, volunteer crisis mappers are now able to compile geographic data as a humanitarian crisis unfolds, allowing individuals across the world to organise as ad hoc groups to participate in data collection. Crisis mappers have created maps of earthquake damage and trapped victims, analysed satellite imagery for signs of armed conflict, and cleaned Twitter data sets to uncover useful information about unfolding extreme weather events like typhoons. Although these volunteers provide useful technical assistance to humanitarian efforts (e.g. when maps and records don’t exist or are lost), their lack of affiliation with “formal” actors, such as the United Nations, and the very fact that they are volunteers, makes them a dubious data source. Indeed, concerns have been raised about the quality of amateur mapping and data efforts, and the uses to which they are put. Most of these concerns assume that volunteers have no professional training. And herein lies the contradiction: by doing the work for free and at their own will the volunteers make these efforts possible and innovative, but this is also why crisis mapping is doubted and questioned by experts. By investigating crisis-mapping volunteers and organisations, Elizabeth Resor’s article “The Neo-Humanitarians: Assessing the Credibility of Organised Volunteer Crisis Mappers” published in Policy & Internet presents evidence of a more professional cadre of volunteers and a means to distinguish between different types of volunteer organisations. Given these organisations now play an increasingly integrated role in humanitarian responses, it’s crucial that their differences are understood and that concerns about the volunteers are answered. We caught up with Elizabeth to discuss her findings: Ed.: We have seen from Citizen Science (and Wikipedia) that large crowds of non-professional volunteers can produce work of incredible value, if projects are set up right.
