How DNA Databases Violate Everyone's Privacy

If you’re an American of European descent, there’s a 60% chance you can be uniquely identified by public information in DNA databases. This is not information that you have made public; this is information your relatives have made public.

Research paper:

“Identity inference of genomic data using long-range familial searches.”

Abstract: Consumer genomics databases have reached the scale of millions of individuals. Recently, law enforcement authorities have exploited some of these databases to identify suspects via distant familial relatives. Using genomic data of 1.28 million individuals tested with consumer genomics, we investigated the power of this technique. We project that about 60% of the searches for individuals of European-descent will result in a third cousin or closer match, which can allow their identification using demographic identifiers. Moreover, the technique could implicate nearly any US-individual of European-descent in the near future. We demonstrate that the technique can also identify research participants of a public sequencing project. Based on these results, we propose a potential mitigation strategy and policy implications to human subject research.

A good news article.

New Data Privacy Regulations

When Mark Zuckerberg testified before both the House and the Senate last month, it became immediately obvious that few US lawmakers had any appetite to regulate the pervasive surveillance taking place on the Internet.

Right now, the only way we can force these companies to take our privacy more seriously is through the market. But the market is broken. First, none of us do business directly with these data brokers. Equifax might have lost my personal data in 2017, but I can’t fire them because I’m not their customer or even their user. I could complain to the companies I do business with who sell my data to Equifax, but I don’t know who they are. Markets require voluntary exchange to work properly. If consumers don’t even know where these data brokers are getting their data from and what they’re doing with it, they can’t make intelligent buying choices.

This is starting to change, thanks to a new law in Vermont and another in Europe. And more legislation is coming.

Vermont first. At the moment, we don’t know how many data brokers collect data on Americans. Credible estimates range from 2,500 to 4,000 different companies. Last week, Vermont passed a law that will change that.

The law does several things to improve the security of Vermonters’ data, but several provisions matter to all of us. First, the law requires data brokers that trade in Vermonters’ data to register annually. And while there are many small local data brokers, the larger companies collect data nationally and even internationally. This will help us get a more accurate look at who’s in this business. The companies also have to disclose what opt-out options they offer, and how people can request to opt out. Again, this information is useful to all of us, regardless of the state we live in. And finally, the companies have to disclose the number of security breaches they’ve suffered each year, and how many individuals were affected.

Admittedly, the regulations imposed by the Vermont law are modest. Earlier drafts of the law included a provision requiring data brokers to disclose how many individuals’ data it has in its databases, what sorts of data it collects and where the data came from, but those were removed as the bill negotiated its way into law. A more comprehensive law would allow individuals to demand to exactly what information they have about them­—and maybe allow individuals to correct and even delete data. But it’s a start, and the first statewide law of its kind to be passed in the face of strong industry opposition.

Vermont isn’t the first to attempt this, though. On the other side of the country, Representative Norma Smith of Washington introduced a similar bill in both 2017 and 2018. It goes further, requiring disclosure of what kinds of data the broker collects. So far, the bill has stalled in the state’s legislature, but she believes it will have a much better chance of passing when she introduces it again in 2019. I am optimistic that this is a trend, and that many states will start passing bills forcing data brokers to be increasingly more transparent in their activities. And while their laws will be tailored to residents of those states, all of us will benefit from the information.

A 2018 California ballot initiative could help. Among its provisions, it gives consumers the right to demand exactly what information a data broker has about them. If it passes in November, once it takes effect, lots of Californians will take the list of data brokers from Vermont’s registration law and demand this information based on their own law. And again, all of us—regardless of the state we live in­—will benefit from the information.

We will also benefit from another, much more comprehensive, data privacy and security law from the European Union. The General Data Protection Regulation (GDPR) was passed in 2016 and took effect on 25 May. The details of the law are far too complex to explain here, but among other things, it mandates that personal data can only be collected and saved for specific purposes and only with the explicit consent of the user. We’ll learn who is collecting what and why, because companies that collect data are going to have to ask European users and customers for permission. And while this law only applies to EU citizens and people living in EU countries, the disclosure requirements will show all of us how these companies profit off our personal data.

It has already reaped benefits. Over the past couple of weeks, you’ve received many e-mails from companies that have you on their mailing lists. In the coming weeks and months, you’re going to see other companies disclose what they’re doing with your data. One early example is PayPal: in preparation for GDPR, it published a list of the over 600 companies it shares your personal data with. Expect a lot more like this.

Surveillance is the business model of the Internet. It’s not just the big companies like Facebook and Google watching everything we do online and selling advertising based on our behaviors; there’s also a large and largely unregulated industry of data brokers that collect, correlate and then sell intimate personal data about our behaviors. If we make the reasonable assumption that Congress is not going to regulate these companies, then we’re left with the market and consumer choice. The first step in that process is transparency. These new laws, and the ones that will follow, are slowly shining a light on this secretive industry.

DNI Wants Research into Secure Multiparty Computation

The Intelligence Advanced Research Projects Activity (IARPA) is soliciting proposals for research projects in secure multiparty computation:

Specifically of interest is computing on data belonging to different—potentially mutually distrusting—parties, which are unwilling or unable (e.g., due to laws and regulations) to share this data with each other or with the underlying compute platform. Such computations may include oblivious verification mechanisms to prove the correctness and security of computation without revealing underlying data, sensitive computations, or both.

My guess is that this is to perform analysis using data obtained from different surveillance authorities.

Indiana's Voter Registration Data Is Frighteningly Insecure

You can edit anyone’s information you want:

The question, boiled down, was haunting: Want to see how easy it would be to get into someone’s voter registration and make changes to it? The offer from Steve Klink—a Lafayette-based public consultant who works mainly with Indiana public school districts—was to use my voter registration record as a case study.

Only with my permission, of course.

“I will not require any information from you,” he texted. “Which is the problem.”

Turns out he didn’t need anything from me. He sent screenshots of every step along the way, as he navigated from the “Update My Voter Registration” tab at the Indiana Statewide Voter Registration System maintained since 2010 at www.indianavoters.com to the blank screen that cleared the way for changes to my name, address, age and more.

The only magic involved was my driver’s license number, one of two log-in options to make changes online. And that was contained in a copy of every county’s voter database, a public record already in the hands of political parties, campaigns, media and, according to Indiana open access laws, just about anyone who wants the beefy spreadsheet.

Crowdsourcing a Database of Hotel Rooms

There’s an app that allows people to submit photographs of hotel rooms around the world into a centralized database. The idea is that photographs of victims of human trafficking are often taken in hotel rooms, and the database will help law enforcement find the traffickers.

I can’t speak to the efficacy of the database—in particular, the false positives—but it’s an interesting crowdsourced approach to the problem.

White House Report on Big Data Discrimination

The White House has released a report on big-data discrimination. From the blog post:

Using case studies on credit lending, employment, higher education, and criminal justice, the report we are releasing today illustrates how big data techniques can be used to detect bias and prevent discrimination. It also demonstrates the risks involved, particularly how technologies can deliberately or inadvertently perpetuate, exacerbate, or mask discrimination.

The purpose of the report is not to offer remedies to the issues it raises, but rather to identify these issues and prompt conversation, research­—and action­—among technologists, academics, policy makers, and citizens, alike.

The report includes a number of recommendations for advancing work in this nascent field of data and ethics. These include investing in research, broadening and diversifying technical leadership, cross-training, and expanded literacy on data discrimination, bolstering accountability, and creating standards for use within both the government and the private sector. It also calls on computer and data science programs and professionals to promote fairness and opportunity as part of an overall commitment to the responsible and ethical use of data.

Helen Nissenbaum on Regulating Data Collection and Use

NYU professor Helen Nissenbaum gave an excellent lecture at Brown University last month, where she rebutted those who think that we should not regulate data collection, only data use: something she calls “big data exceptionalism.” Basically, this is the idea that collecting the “haystack” isn’t the problem; it what is done with it that is. (I discuss this same topic in Data and Goliath, on pages 197-9.)

In her talk, she makes a very strong argument that the problem is one of domination. Contemporary political philosopher Philip Pettit has written extensively about a republican conception of liberty. He defines domination as the extent one person has the ability to interfere with the affairs of another.

Under this framework, the problem with wholesale data collection is not that it is used to curtail your freedom; the problem is that the collector has the power to curtail your freedom. Whether they use it or not, the fact that they have that power over us is itself a harm.
