‘Data is a fingerprint’: why you aren’t as anonymous as you think online


Olivia Solon at The Guardian: “In August 2016, the Australian government released an “anonymised” data set comprising the medical billing records, including every prescription and surgery, of 2.9 million people.

Names and other identifying features were removed from the records in an effort to protect individuals’ privacy, but a research team from the University of Melbourne soon discovered that it was simple to re-identify people, and learn about their entire medical history without their consent, by comparing the dataset to other publicly available information, such as reports of celebrities having babies or athletes having surgeries.

The government pulled the data from its website, but not before it had been downloaded 1,500 times.

This privacy nightmare is one of many examples of seemingly innocuous, “de-identified” pieces of information being reverse-engineered to expose people’s identities. And it’s only getting worse as people spend more of their lives online, sprinkling digital breadcrumbs that can be traced back to them to violate their privacy in ways they never expected.

Nameless New York taxi logs were compared with paparazzi shots at locations around the city to reveal that Bradley Cooper and Jessica Alba were bad tippers. In 2017 German researchers were able to identify people based on their “anonymous” web browsing patterns. This week University College London researchers showed how they could identify an individual Twitter user based on the metadata associated with their tweets, while the fitness tracking app Polar revealed the homes and in some cases names of soldiers and spies.

“It’s convenient to pretend it’s hard to re-identify people, but it’s easy. The kinds of things we did are the kinds of things that any first-year data science student could do,” said Vanessa Teague, one of the University of Melbourne researchers to reveal the flaws in the open health data.

One of the earliest examples of this type of privacy violation occurred in 1996 when the Massachusetts Group Insurance Commission released “anonymised” data showing the hospital visits of state employees. As with the Australian data, the state removed obvious identifiers like name, address and social security number. Then the governor, William Weld, assured the public that patients’ privacy was protected….(More)”.

Activism in the Social Media Age


PewInternet: “This month marks the fifth anniversary of the #BlackLivesMatter hashtag, which was first coined following the acquittal of George Zimmerman in the shooting death of unarmed black teenager Trayvon Martin. In the course of those five years, #BlackLivesMatter has become an archetypal example of modern protests and political engagement on social media: A new Pew Research Center analysis of public tweets finds the hashtag has been used nearly 30 million times on Twitter – an average of 17,002 times per day – as of May 1, 2018.

Use of the #BlackLivesMatter hashtag on Twitter periodically spikes in response to major news events

The conversations surrounding this hashtag often center on issues related to race, violence and law enforcement, and its usage periodically surges surrounding real-world events – most prominently, during the police-related deaths of Alton Sterling and Philando Castile and the subsequent shooting of police officers in Dallas, Texas, and Baton Rouge, Louisiana, in July 2016.1

The rise of the #BlackLivesMatter hashtag – along with others like #MeToo and #MAGA (Make America Great Again) – has sparked a broader discussion about the effectiveness and viability of using social media for political engagement and social activism. To that end, a new survey by the Center finds that majorities of Americans do believe these sites are very or somewhat important for accomplishing a range of political goals, such as getting politicians to pay attention to issues (69% of Americans feel these platforms are important for this purpose) or creating sustained movements for social change (67%).

Certain groups of social media users – most notably, those who are black or Hispanic – view these platforms as an especially important tool for their own political engagement. For example, roughly half of black social media users say these platforms are at least somewhat personally important to them as a venue for expressing their political views or for getting involved with issues that are important to them. Those shares fall to around a third among white social media users.2

At the same time, the public as a whole expresses mixed views about the potential broader impact these sites might be having on political discourse and the nature of political activism. Some 64% of Americans feel that the statement “social media help give a voice to underrepresented groups” describes these sites very or somewhat well. But a larger share say social networking sites distract people from issues that are truly important (77% feel this way), and 71% agree with the assertion that “social media makes people believe they’re making a difference when they really aren’t.” Blacks and whites alike offer somewhat mixed assessments of the benefits and costs of activism on social media. But larger majorities of black Americans say these sites promote important issues or give voice to underrepresented groups, while smaller shares of blacks feel that political engagement on social media produces significant downsides in the form of a distracted public or “slacktivism.”…(More)”.

Meet the Numtots: the millennials who find fixing public transport sexy


Elle Hunt in The Guardian: “Who makes a Facebook meme group about trains? The Numtots, that’s who: a global network of millennials who want to make cities better

The year is 2025. There are no cars, only public transport and bicycles. Four-lane highways have been replaced by bike paths. Pedestrians share the pavements with cyclists. The air is clean (because the buses are electric), and the living is easy.

This is the future the Numtots want.

Predominantly millennials with a passion for public transport, urban planning and internet humour, Numtots’ interests intersect in New Urbanist Memes for Transit-Oriented Teens, the Facebook group from which they derive their nickname. There, nearly 100,000 of them discuss and debate their perfect city, or transit lines in their area, or perpendicular traffic flow and improvisational vehicle pathing….Numtots – or just ’tots – are the sorts of older teens through to thirtysomethings who identify as being “irrationally excited” for the forthcoming Maryland purple line; who claim their first word as a child was “bus” (“I think I was destined to become a Numtot …”); who stridently propose ideas for “what the Amtrak system should look like” (“Fight me if you don’t like it”); and who mercilessly make fun of Richard Florida’s leather jacket….

Numtots’ guiding principles are broadly summed up by the page’s URL: “What would Jane Jacobs do?”…The enthusiastic response to the group – and the Generation Y-led “yimby” movement for high-density housing it dovetails with – suggests there may be something fundamentally millennial about urbanism. “I think at first people were really excited that they had a place to talk about living in cities,” says Orenstein, also 21. “But as the group has picked up steam, more people are joining that weren’t interested in the issues but are finding that maybe, actually, they are.” It makes sense: improving public transport, transitioning to renewable energy and investing in future-focused infrastructure are not often vote winners, being costly and slow to enact – but young people have more of a stake in seeing them put into action….(More)”.

Sentiment Analysis of Big Data: Methods, Applications, and Open Challenges


Paper by Shahid Shayaa et al at IEEE: “The development of IoT technologies and the massive admiration and acceptance of social media tools and applications, new doors of opportunity have been opened for using data analytics in gaining meaningful insights from unstructured information. The application of opinion mining and sentiment analysis (OMSA) in the era of big data have been used a useful way in categorize the opinion into different sentiment and in general evaluating the mood of the public. Moreover, different techniques of OMSA have been developed over the years in different datasets and applied to various experimental settings. In this regard, this study presents a comprehensive systematic literature review, aims to discuss both technical aspect of OMSA (techniques, types) and non-technical aspect in the form of application areas are discussed. Furthermore, the study also highlighted both technical aspect of OMSA in the form of challenges in the development of its technique and non-technical challenges mainly based on its application. These challenges are presented as a future direction for research….(More)”.

Book edited by Alexander V. Laskin: “…edited collection of cutting edge research on the practical applications of diverse types of emerging media technologies in a variety of industries and in many different regions of the world. In recent years, emergent social media have initiated a revolution comparable in impact to the industrial revolution or the invention of the Internet. Today, social media’s usage statistics are mind-boggling: almost two billion people are Facebook users, over one billion people communicate via What’sApp, over forty billion pictures are posted on Instagram, and over one million snaps are sent on Snapchat daily. This edited collection analyzes the influence of emerging media technologies on governments, global organizations, non-profits, corporations, museums, restaurants, first responders, sports, medicine, television, and free speech. It studies such new media phenomena as brandjacking, crowd-funding, crowd-mapping, augmented reality, mHealth, and transmedia, focusing specifically on new media platforms like Facebook and Facebook Live, Twitter, Sina Weibo, Yelp, and other mobile apps….(More)”.

What Democracy Needs Now


The RSA Chief Executive’s Lecture 2018 by Matthew Taylor: “In 1989 with the fall of the Berlin Wall still echoing, Francis Fukuyama prophesied the global triumph of liberal democracy and the end of history. Thirty years on it is not history in jeopardy but liberal democracy itself.

China – the rising global power – is thriving with a system which combines economic freedom with political autocracy. There is the growth of what Yascha Mounk calls illiberal democracies – countries with notionally free elections but without the liberal foundations of accountability, civil liberties and cultural openness. The issue with nations like Russia, Hungary and Turkey, and with those exhibiting a backlash against liberalism like America and Italy, is not just how they operate but the tendency for populism – when given the excuse or opportunity – to drift towards authoritarianism.

While the alternatives to the liberal democratic system grow more confident the citizens living in those systems become more restless. Politicians and political institutions in countries are viewed with dismay and contempt. We don’t like them, we don’t trust them, we don’t think they can solve the problems that most matter to us. The evidence, particularly from the US, is starting to suggest that disillusionment with politics is now becoming indifference towards democracy itself.

Will liberal democracy come back into fashion – is this a cycle or is it a trend? Behind the global patterns each country is different, but think of what is driving anger and disillusionment in our own.

Living standards flat-lining for longer than at any time since the industrial revolution. A decade of austerity leaving our public services threadbare and in a mode of continual crisis management. From social care to gangs, from cybercrime to mental health, how many of us think Government is facing up to the problems let alone developing solutions?

Inequality, having risen precipitously in the 1980s, remains stubbornly high, fuelling anger about elites and making not just the economic divide but all divisions worse.

Social media – where increasingly people get their information and engage in political discourse – has the seemingly in-built tendency to confirm prejudice and polarise opinion.

The great intertwined forces shaping the future – globalisation, unprecedented corporate power, technological change – continue to reinforce a sense in people, places and nations that they have no agency. Yet the hunger to take back control which started as tragedy is rapidly becoming a farce.

If this is the warm climate in which disillusionment has taken root and grown it shows few signs of cooling.

For all its many failings, I have always believed that over the long term liberal democracy would carry on making lives better for most people most of the time. As a progressive my guiding star is what Roberto Unger has called ‘the larger life for all’. But for the first time, I view the future with more fear than hope.

There are those who disparage pessimism. To them the backlash against liberalism, the signs of a declining faith in democracy, are passing responses to failure and misfortune. Populism will give the system the wake-up call it needs. In time a new generation of leaders will renew the system. Populism need neither be extreme nor beget authoritarianism – look at Macron.

This underestimates the dangers that face us. It is too reminiscent of those who believed, until the results came in, that the British people would not take the risk of Brexit or that the Americans would reject the madness of Trump. It underestimates too how the turn against liberal democracy in one country can beget it in another. Paradoxically, today nationalists seem more able to collaborate with each other than countries ostensibly committed to internationalism. Chaos spreads more quickly than order. Global treaties and institutions take years to agree, they can breakdown overnight.

Of course, liberal democracy has failed over and again to live up to its own promise. But the fact that things need to change doesn’t mean they can’t get a whole lot worse.

We are also in danger of underestimating the coherence and confidence of liberalism’s critics. Last month Hungarian Prime Minister Victor Orban made a powerful speech defending his brand of nationalist populism and boasting of his growing alliances across Europe. He appealed to the continent’s centre-right to recognise that it has more in common with conservative nationalism than the EU’s liberal establishment. There are aspects of Orban’s analysis which have an understandable appeal to the mainstream, but remember this is also a man who is unashamedly hostile to Islam, contemptuous of humanitarianism, and who is playing fast and loose with democratic safeguards in his own country.

We may disagree about how malign or dangerous are figures like Orban or Erdogan, or Trump or Salvini, but surely we can agree that those who want to defend the open, pluralistic, inclusive values of liberal democracy must try to make a better case for what we believe?

In part this involves defending the record of liberal societies in improving lives, creating opportunities and keeping the peace, at least between themselves. But it also means facing up to what is going wrong and what must change.

Complex problems are rarely addressed with a single solution. To ever again achieve the remarkable and unprecedented economic and social advances of the three decades after the Second World War, liberal democracy needs profound renewal. But change must start some place. This evening I want to argue that place should be the way we do democracy itself…(More) (Video)”.

Migration Data using Social Media


European Commission JRC Technical Report: “Migration is a top political priority for the European Union (EU). Data on international migrant stocks and flows are essential for effective migration management. In this report, we estimated the number of expatriates in 17 EU countries based on the number of Facebook Network users who are classified by Facebook as “expats”. To this end, we proposed a method for correcting the over- or under-representativeness of Facebook Network users compared to countries’ actual population.

This method uses Facebook penetration rates by age group and gender in the country of previous residence and country of destination of a Facebook expat. The purpose of Facebook Network expat estimations is not to reproduce migration statistics, but rather to generate separate estimates of expatriates, since migration statistics and Facebook Network expats estimates do not measure the same quantities of interest.

Estimates of social media application users who are classified as expats can be a timely, low-cost, and almost globally available source of information for estimating stocks of international migrants. Our methodology allowed for the timely capture of the increase of Venezuelan migrants in Spain. However, there are important methodological and data integrity issues with using social media data sources for studying migration-related phenomena. For example, our methodology led us to significantly overestimate the number of expats from Philippines in Spain and in Italy and there is no evidence that this overestimation may be valid. While research on the use of big data sources for migration is in its infancy, and the diffusion of internet technologies in less developed countries is still limited, the use of big data sources can unveil useful insights on quantitative and qualitative characteristics of migration….(More)”.

Google.gov


Adam J. White at New Atlantis: “Google exists to answer our small questions. But how will we answer larger questions about Google itself? Is it a monopoly? Does it exert too much power over our lives? Should the government regulate it as a public utility — or even break it up?

In recent months, public concerns about Google have become more pronounced. This February, the New York Times Magazine published “The Case Against Google,” a blistering account of how “the search giant is squelching competition before it begins.” The Wall Street Journal published a similar article in January on the “antitrust case” against Google, along with Facebook and Amazon, whose market shares it compared to Standard Oil and AT&T at their peaks. Here and elsewhere, a wide array of reporters and commentators have reflected on Google’s immense power — not only over its competitors, but over each of us and the information we access — and suggested that the traditional antitrust remedies of regulation or breakup may be necessary to rein Google in.

Dreams of war between Google and government, however, obscure a much different relationship that may emerge between them — particularly between Google and progressive government. For eight years, Google and the Obama administration forged a uniquely close relationship. Their special bond is best ascribed not to the revolving door, although hundreds of meetings were held between the two; nor to crony capitalism, although hundreds of people have switched jobs from Google to the Obama administration or vice versa; nor to lobbying prowess, although Google is one of the top corporate lobbyists.

Rather, the ultimate source of the special bond between Google and the Obama White House — and modern progressive government more broadly — has been their common ethos. Both view society’s challenges today as social-engineering problems, whose resolutions depend mainly on facts and objective reasoning. Both view information as being at once ruthlessly value-free and yet, when properly grasped, a powerful force for ideological and social reform. And so both aspire to reshape Americans’ informational context, ensuring that we make choices based only upon what they consider the right kinds of facts — while denying that there would be any values or politics embedded in the effort.

Addressing an M.I.T. sports-analytics conference in February, former President Obama said that Google, Facebook, and prominent Internet services are “not just an invisible platform, but they are shaping our culture in powerful ways.” Focusing specifically on recent outcries over “fake news,” he warned that if Google and other platforms enable every American to personalize his or her own news sources, it is “very difficult to figure out how democracy works over the long term.” But instead of treating these tech companies as public threats to be regulated or broken up, Obama offered a much more conciliatory resolution, calling for them to be treated as public goods:

I do think that the large platforms — Google and Facebook being the most obvious, but Twitter and others as well that are part of that ecosystem — have to have a conversation about their business model that recognizes they are a public good as well as a commercial enterprise.

This approach, if Google were to accept it, could be immensely consequential….(More)”.

Ways to think about machine learning


Benedict Evans: “We’re now four or five years into the current explosion of machine learning, and pretty much everyone has heard of it. It’s not just that startups are forming every day or that the big tech platform companies are rebuilding themselves around it – everyone outside tech has read the Economist or BusinessWeek cover story, and many big companies have some projects underway. We know this is a Next Big Thing.

Going a step further, we mostly understand what neural networks might be, in theory, and we get that this might be about patterns and data. Machine learning lets us find patterns or structures in data that are implicit and probabilistic (hence ‘inferred’) rather than explicit, that previously only people and not computers could find. They address a class of questions that were previously ‘hard for computers and easy for people’, or, perhaps more usefully, ‘hard for people to describe to computers’. And we’ve seen some cool (or worrying, depending on your perspective) speech and vision demos.

I don’t think, though, that we yet have a settled sense of quite what machine learning means – what it will mean for tech companies or for companies in the broader economy, how to think structurally about what new things it could enable, or what machine learning means for all the rest of us, and what important problems it might actually be able to solve.

This isn’t helped by the term ‘artificial intelligence’, which tends to end any conversation as soon as it’s begun. As soon as we say ‘AI’, it’s as though the black monolith from the beginning of 2001 has appeared, and we all become apes screaming at it and shaking our fists. You can’t analyze ‘AI’.

Indeed, I think one could propose a whole list of unhelpful ways of talking about current developments in machine learning. For example:

  • Data is the new oil
  • Google and China (or Facebook, or Amazon, or BAT) have all the data
  • AI will take all the jobs
  • And, of course, saying AI itself.

More useful things to talk about, perhaps, might be:

  • Automation
  • Enabling technology layers
  • Relational databases. …(More).

Blockchain Ethical Design Framework


Report by Cara LaPointe and Lara Fishbane: “There are dramatic predictions about the potential of blockchain to “revolutionize” everything from worldwide financial markets and the distribution of humanitarian assistance to the very way that we outright recognize human identity for billions of people around the globe. Some dismiss these claims as excessive technology hype by citing flaws in the technology or robustness of incumbent solutions and infrastructure.

The reality will likely fall somewhere between these two extremes across multiple sectors. Where initial applications of blockchain were focused on the financial industry, current applications have rapidly expanded to address a wide array of sectors with major implications for social impact.

This paper aims to demonstrate the capacity of blockchain to create scalable social impact and to identify the elements that need to be addressed to mitigate challenges in its application. We are at a moment when technology is enabling society to experiment with new solutions and business models. Ubiquity and global reach, increased capabilities, and affordability have made technology a critical tool for solving problems, making this an exciting time to think about achieving greater social impact. We can address issues for underserved or marginalized people in ways that were previously unimaginable.

Blockchain is a technology that holds real promise for dealing with key inefficiencies and transforming operations in the social sector and for improving lives. Because of its immutability and decentralization, blockchain has the potential to create transparency, provide distributed verification, and build trust across multiple systems. For instance, blockchain applications could provide the means for establishing identities for individuals without identification papers, improving access to finance and banking services for underserved populations, and distributing aid to refugees in a more transparent and efficient manner. Similarly, national and subnational governments are putting land registry information onto blockchains to create greater transparency and avoid corruption and manipulation by third parties.

From increasing access to capital, to tracking health and education data across multiple generations, to improving voter records and voting systems, blockchain has countless potential applications for social impact. As developers take on building these types of solutions, the social effects of blockchain can be powerful and lasting. With the potential for such a powerful impact, the design, application, and approach to the development and implementation of blockchain technologies have long-term implications for society and individuals.

This paper outlines why intentionality of design, which is important with any technology, is particularly crucial with blockchain, and offers a framework to guide policymakers and social impact organizations. As social media, cryptocurrencies, and algorithms have shown, technology is not neutral. Values are embedded in the code. How the problem is defined and by whom, who is building the solution, how it gets programmed and implemented, who has access, and what rules are created have consequences, in intentional and unintentional ways. In the applications and implementation of blockchain, it is critical to understand that seemingly innocuous design choices have resounding ethical implications on people’s lives.

This white paper addresses why intentionality of design matters, identifies the key questions that should be asked, and provides a framework to approach use of blockchain, especially as it relates to social impact. It examines the key attributes of blockchain, its broad applicability as well as its particular potential for social impact, and the challenges in fully realizing that potential. Social impact organizations and policymakers have an obligation to understand the ethical approaches used in designing blockchain technology, especially how they affect marginalized and vulnerable populations….(More)”
