Springwise: “There’s more traffic on today’s city streets than there ever has been, and managing it all can prove to be a headache for local authorities and transport bodies. In the past, we’ve seen the City of Calgary in Canada detect drivers’ Bluetooth signals to develop a map of traffic congestion. Now the EAR-IT project in Santander, Spain, is using acoustic sensors to measure the sounds of city streets and determine real time activity on the ground.
Launched as part of the autonomous community’s SmartSantander initiative, the experimental scheme placed hundreds of acoustic processing units around the region. These pick up the sounds being made in any given area and, when processed through an audio recognition engine, can provide data about what’s going on on the street. Smaller ‘motes’ were also developed to provide more accurate location information about each sound.
Created by members of Portugal’s UNINOVA institute and IT consultants EGlobalMark, the system was able to use city noises to detect things such as traffic congestion, parking availability and the location of emergency vehicles based on their sirens. It could then automatically trigger smart signs to display up-to-date information, for example.
The team particularly focused on a junction near the city hospital that’s a hotspot for motor accidents. Rather than force ambulance drivers to risk passing through a red light and into lateral traffic, the sensors were able to detect when and where an emergency vehicle was coming through and automatically change the lights in their favor.
The system could also be used to pick up ‘sonic events’ such as gunshots or explosions and detect their location. The researchers have also trialled an indoor version that can sense if an elderly resident has fallen over or to turn lights off when the room becomes silent.”
Why the World Needs Anonymous
Gabriella Coleman at MIT Technology Review: “Anonymity is under attack, and yet the actions of a ragtag band of hackers, activists, and rabble-rousers reveal how important it remains.
“It’s time to end anonymous comments sections,” implored Kevin Wallsten and Melinda Tarsi in the Washington Post this August. In the U.K., a parliamentary committee has even argued for a “cultural shift” against treating pseudonymous comments as trustworthy. This assault is matched by pervasive practices of monitoring and surveillance, channeled through a stunning variety of mechanisms—from CCTV cameras to the constant harvesting of digital data.
But just as anonymity’s value has sunk to a new low in the eyes of some, a protest movement in favor of concealment has appeared. The hacker collective Anonymous is most famous for its controversial crusades against the likes of dictators, corporations, and pseudo-religions like Scientology. But the group is also the embodiment of this new spirit.
Anonymous may strike a reader as unique, but its efforts represent just the latest in experimentation with anonymous speech as a conduit for political expression. Anonymous expression has been foundational to our political culture, characterizing monumental declarations like the Federalist Papers, and the Supreme Court has repeatedly granted anonymous speech First Amendment protection.
The actions of this group are also important because anonymity remains important to us all. Universally enforcing disclosure of real identities online would limit the possibilities for whistle-blowing and voicing unpopular beliefs—processes essential to any vibrant democracy. And just as anonymity can engender disruptive and antisocial behavior such as trolling, it can provide a means of pushing back against increased surveillance.
By performing a role increasingly unavailable to most Internet users as they participate in social networks and other gated communities requiring real names, Anonymous dramatizes the existence of other possibilities. Its members symbolically incarnate struggles against the constant, blanket government surveillance revealed by Edward Snowden and many before him.
As an anthropologist who has spent half a dozen years studying Anonymous, I’ve have had the unique opportunity to witness and experience just how these activists conceive of and enact obfuscation. It is far from being implemented mindlessly. Indeed, there are important ethical lessons that we can draw from their successes and failures.
Often Anonymous activists, or “Anons,” interact online under the cover of pseudo-anonymity. Typically, this takes the form of a persistent nickname, otherwise known as a handle, around which a reputation necessarily accrues. Among the small fraction of law-breaking Anons, pseudo-anonymity is but one among a roster of tactics for achieving operational security. These include both technical solutions, such as encryption and anonymizing software, and cultivation of the restraint necessary to prevent the disclosure of personal information.
The great majority of Anonymous participants are neither hackers nor lawbreakers but must nonetheless remain circumspect in what they reveal about themselves and others. Sometimes, ignorance is the easiest way to ensure protection. A participant who helped build up one of the larger Anonymous accounts erected a self-imposed fortress between herself and the often-private Internet Relay Chat channels where law-breaking Anons cavorted and planned actions. It was a “wall,” as she put it, which she sought never to breach.
During the course of my research, I eschewed anonymity and mitigated risk by erecting the same wall, making sure not to climb over it. But some organizers were more intrepid. Since they associated with lawbreakers or even witnessed planning of illegal activity on IRC, they chose to cloak themselves for self-protection.
Regardless of the reasons for maintaining anonymity, it shaped many of the ethical norms and mores of the group. The source of this ethic is partly indebted to 4chan, a hugely popular, and deeply subversive, image board that enforced the name “Anonymous” for all users, thus hatching the idea’s potential (see “Radical Opacity”)….

Open Elections
“Welcome to OpenElections Our goal is to create the first free, comprehensive, standardized, linked set of election data for the United States, including federal and statewide offices. No freely available comprehensive source of official election results exists. The current options for election data can be difficult to find and use or financially out-of-reach for most journalists and civic hackers. We want the people who work with election data to be able to get what they need, whether that’s a CSV file for stories and data analysis or JSON usable for web applications and interactive graphics. OpenElections is generously supported by the John S. and James L. Knight Foundation’s Knight News Challenge.”
Gov.uk quietly disrupts the problem of online identity login
The Guardian: “A new “verified identity” scheme for gov.uk is making it simpler to apply for a new driving licence, passport or to file a tax return online, allowing users to register securely using one log in that connects and securely stores their personal data.
After nearly a year of closed testing with a few thousand Britons, the “Gov.UK Verify” scheme quietly opened to general users on 14 October, expanding across more services. It could have as many as half a million users with a year.
The most popular services are expected to be one for tax credit renewals, and CAP farm information – both expected to have around 100,000 users by April next year, and on their own making up nearly half of the total use.
The team behind the system claim this is a world first. Those countries that have developed advanced government services online, such as Estonia, rely on state identity cards – which the UK has rejected.
“This is a federated model of identity, not a centralised one,” said Janet Hughes, head of policy and engagement at the Government Digital Service’s identity assurance program, which developed and tested the system.
How it works
The Verify system has taken three years to develop, and involves checking a user’s identity against details from a range of sources, including credit reference agencies, utility bills, driving licences and mobile provider bills.
But it does not retain those pieces of information, and the credit checking companies do not know what service is being used. Only a mobile or landline number is kept in order to send verification codes for subsequent logins.
When people subsequently log in, they would have to provide a user ID and password, and verify their identity by entering a code sent to related stored phone number.
To enrol in the system, users have to be over 19, living in the UK, and been resident for over 12 months. A faked passport would not be sufficient: “they would need a very full false ID, and have to not appear on any list of fraudulent identities,” one source at the GDS told the Guardian.
Banks now following gov.uk’s lead
Government developers are confident that it presents a higher barrier to authentication than any other digital service – so that fraudulent transactions will be minimised. That has interested banks, which are understood to be expressing interest in using the same service to verify customer identities through an arms-length verification system.
The government system would not pass on people’s data, but would instead verify that someone is who they claim to be, much like Twitter and Facebook verify users’ identity to log in to third party sites, yet don’t share their users’ data.
The US, Canada and New Zealand have also expressed interest in following up the UK’s lead in the system, which requires separate pieces of verified information about themselves from different sources.
The system then cross-references that verified information with credit reference agencies and other sources, which can include a mobile phone provider, passport, bank account, utility bill or driving licence.
The level of confidence in an individual’s identity is split into four levels. The lowest is for the creation of simple accounts to receive reports or updates: “we don’t need to know who it is, only that it’s the same person returning,” said Hughes.
Level 2 requires that “on the balance of probability” someone is who they say they are – which is the level to which Verify will be able to identify people. Hughes says that this will cover the majority of services.
Level 3 requires identity “beyond reasonable doubt” – perhaps including the first application for a passport – and Level 4 would require biometric information to confirm individual identity.
Seattle Launches Sweeping, Ethics-Based Privacy Overhaul
for the Privacy Advisor: “The City of Seattle this week launched a citywide privacy initiative aimed at providing greater transparency into the city’s data collection and use practices.
To that end, the city has convened a group of stakeholders, the Privacy Advisory Committee, comprising various government departments, to look at the ways the city is using data collected from practices as common as utility bill payments and renewing pet licenses or during the administration of emergency services like police and fire. By this summer, the committee will deliver the City Council suggested principles and a “privacy statement” to provide direction on privacy practices citywide.
In addition, the city has partnered with the University of Washington, where Jan Whittington, assistant professor of urban design and planning and associate director at the Center for Information Assurance and Cybersecurity, has been given a $50,000 grant to look at open data, privacy and digital equity and how municipal data collection could harm consumers.
Responsible for all things privacy in this progressive city is Michael Mattmiller, who was hired to the position of chief technology officer (CTO) for the City of Seattle in June. Before his current gig, he worked as a senior strategist in enterprise cloud privacy for Microsoft. He said it’s an exciting time to be at the helm of the office because there’s momentum, there’s talent and there’s intention.
“We’re at this really interesting time where we have a City Council that strongly cares about privacy … We have a new police chief who wants to be very good on privacy … We also have a mayor who is focused on the city being an innovative leader in the way we interact with the public,” he said.
In fact, some City Council members have taken it upon themselves to meet with various groups and coalitions. “We have a really good, solid environment we think we can leverage to do something meaningful,” Mattmiller said….
Armbruster said the end goal is to create policies that will hold weight over time.
“I think when looking at privacy principles, from an ethical foundation, the idea is to create something that will last while technology dances around us,” she said, adding the principles should answer the question, “What do we stand for as a city and how do we want to move forward? So any technology that falls into our laps, we can evaluate and tailor or perhaps take a pass on as it falls under our ethical framework.”
The bottom line, Mattmiller said, is making a decision that says something about Seattle and where it stands.
“How do we craft a privacy policy that establishes who we want to be as a city and how we want to operate?” Mattmiller asked.”
Could digital badges clarify the roles of co-authors?
at AAAS Science Magazine: “Ever look at a research paper and wonder how the half-dozen or more authors contributed to the work? After all, it’s usually only the first or last author who gets all the media attention or the scientific credit when people are considered for jobs, grants, awards, and more. Some journals try to address this issue with the “authors’ contributions” sections within a paper, but a collection of science, publishing, and software groups is now developing a more modern solution—digital “badges,” assigned on publication of a paper online, that detail what each author did for the work and that the authors can link to their profiles elsewhere on the Web.
Those organizations include publishers BioMed Central and the Public Library of Science; The Wellcome Trust research charity; software development groups Mozilla Science Lab (a group of researchers, developers, librarians, and publishers) and Digital Science (a software and technology firm); and ORCID, an effort to assign researchers digital identifiers. The collaboration presented its progress on the project at the Mozilla Festival in London that ended last week. (Mozilla is the open software community behind the Firefox browser and other programs.)
The infrastructure of the badges is still being established, with early prototypes scheduled to launch early next year, according to Amye Kenall, the journal development manager of open data initiatives and journals at BioMed Central. She envisions the badge process in the following way: Once an article is published, the publisher would alert software maintained by Mozilla to automatically set up an online form, where authors fill out roles using a detailed contributor taxonomy. After the authors have completed this, the badges would then appear next to their names on the journal article, and double-clicking on a badge would lead to the ORCID site for that particular author, where the author’s badges, integrated with their publishing record, live….
The parties behind the digital badge effort are “looking to change behavior” of scientists in the competitive dog-eat-dog world of academia by acknowledging contributions, says Kaitlin Thaney, director of Mozilla Science Lab. Amy Brand, vice president of academic and research relations and VP of North America at Digital Science, says that the collaboration believes that the badges should be optional, to accommodate old-fashioned or less tech-savvy authors. She says that the digital credentials may improve lab culture, countering situations where junior scientists are caught up in lab politics and the “star,” who didn’t do much of the actual research apart from obtaining the funding, gets to be the first author of the paper and receive the most credit. “All of this calls out for more transparency,” Brand says….”
Urban Observatory Is Snapping 9,000 Images A Day Of New York City
FastCo-Exist: “Astronomers have long built observatories to capture the night sky and beyond. Now researchers at NYU are borrowing astronomy’s methods and turning their cameras towards Manhattan’s famous skyline.
NYU’s Center for Urban Science and Progress has been running what’s likely the world’s first “urban observatory” of its kind for about a year. From atop a tall building in downtown Brooklyn (NYU won’t say its address, due to security concerns), two cameras—one regular one and one that captures infrared wavelengths—take panoramic images of lower and midtown Manhattan. One photo is snapped every 10 seconds. That’s 8,640 images a day, or more than 3 million since the project began (or about 50 terabytes of data).

One photo is snapped every 10 seconds. That’s 8,640 images a day, or more than 3 million since the project began (or about 50 terabytes of data).
“The real power of the urban observatory is that you have this synoptic imaging. By synoptic imaging, I mean these large swaths of the city,” says the project’s chief scientist Gregory Dobler, a former astrophysicist at Harvard University and the University of California, Santa Barbara who now heads the 15-person observatory team at NYU.
Dobler’s team is collaborating with New York City officials on the project, which is now expanding to set up stations that study other parts of Manhattan and Brooklyn. Its major goal is to discover information about the urban landscape that can’t be seen at other scales. Such data could lead to applications like tracking which buildings are leaking energy (with the infrared camera), or measuring occupancy patterns of buildings at night, or perhaps detecting releases of toxic chemicals in an emergency.
The video above is an example. The top panel cycles through a one-minute slice of observatory images. The bottom panel is an analysis of the same images in which everything that remains static in each image is removed, such as buildings, trees, and roads. What’s left is an imprint of everything in flux within the scene—the clouds, the cars on the FDR Drive, the boat moving down the East River, and, importantly, a plume of smoke that puffs out of a building.
“Periodically, a building will burp,” says Dobler. “It’s hard to see the puffs of smoke . . . but we can isolate that plume and essentially identify it.” (As Dobler has done by highlighting it in red in the top panel).
To the natural privacy concerns about this kind of program, Dobler emphasizes that the pictures are only from an 8 megapixel camera (the same found in the iPhone 6) and aren’t clear enough to see inside a window or make out individuals. As a further privacy safeguard, the images are analyzed to only look at “aggregate” measures—such as the patterns of nighttime energy usage—rather than specific buildings. “We’re not really interested in looking at a given building, and saying, hey, these guys are particular offenders,” he says (He also says the team is not looking at uses for the data in security applications.) However, Dobler was not able to answer a question as to whether the project’s partners at city agencies are able to access data analysis for individual buildings….”
How Wikipedia Data Is Revolutionizing Flu Forecasting
They say their model has the potential to transform flu forecasting from a black art to a modern science as well-founded as weather forecasting.
Flu takes between 3,000 and 49,000 lives each year in the U.S. so an accurate forecast can have a significant impact on the way society prepares for the epidemic. The current method of monitoring flu outbreaks is somewhat antiquated. It relies on a voluntary system in which public health officials report the percentage of patients they see each week with influenza-like illnesses. This is defined as the percentage of people with a temperature higher than 100 degrees, a cough and no other explanation other than flu.
These numbers give a sense of the incidence of flu at any instant but the accuracy is clearly limited. They do not, for example, account for people with flu who do not seek treatment or people with flu-like symptoms who seek treatment but do not have flu.
There is another significant problem. The network that reports this data is relatively slow. It takes about two weeks for the numbers to filter through the system so the data is always weeks old.
That’s why the CDC is interested in finding new ways to monitor the spread of flu in real time. Google, in particular, has used the number of searches for flu and flu-like symptoms to forecast flu in various parts of the world. That approach has had considerable success but also some puzzling failures. One problem, however, is that Google does not make its data freely available and this lack of transparency is a potential source of trouble for this kind of research.
So Hickmann and co have turned to Wikipedia. Their idea is that the variation in numbers of people accessing articles about flu is an indicator of the spread of the disease. And since Wikipedia makes this data freely available to any interested party, it is an entirely transparent source that is likely to be available for the foreseeable future….

The New Thing in Google Flu Trends Is Traditional Data
Steve Lohr in the New York Times: “Google is giving its Flu Trends service an overhaul — “a brand new engine,” as it announced in a blog post on Friday.
The new thing is actually traditional data from the Centers for Disease Control and Prevention that is being integrated into the Google flu-tracking model. The goal is greater accuracy after the Google service had been criticized for consistently over-estimating flu outbreaks in recent years.
The main critique came in an analysis done by four quantitative social scientists, published earlier this year in an article in Science magazine, “The Parable of Google Flu: Traps in Big Data Analysis.” The researchers found that the most accurate flu predictor was a data mash-up that combined Google Flu Trends, which monitored flu-related search terms, with the official C.D.C. reports from doctors on influenza-like illness.
The Google Flu Trends team is heeding that advice. In the blog post, written by Christian Stefansen, a Google senior software engineer, wrote, “We’re launching a new Flu Trends model in the United States that — like many of the best performing methods in the literature — takes official CDC flu data into account as the flu season progresses.”
Google’s flu-tracking service has had its ups and downs. Its triumph came in 2009, when it gave an advance signal of the severity of the H1N1 outbreak, two weeks or so ahead of official statistics. In a 2009 article in Nature explaining how Google Flu Trends worked, the company’s researchers did, as the Friday post notes, say that the Google service was not intended to replace official flu surveillance methods and that it was susceptible to “false alerts” — anything that might prompt a surge in flu-related search queries.
Yet those caveats came a couple of pages into the Nature article. And Google Flu Trends became a symbol of the superiority of the new, big data approach — computer algorithms mining data trails for collective intelligence in real time. To enthusiasts, it seemed so superior to the antiquated method of collecting health data that involved doctors talking to patients, inspecting them and filing reports.
But Google’s flu service greatly overestimated the number of cases in the United States in the 2012-13 flu season — a well-known miss — and, according to the research published this year, has persistently overstated flu cases over the years. In the Science article, the social scientists called it “big data hubris.”
Governing the Smart, Connected City
Blog by Susan Crawford at HBR: “As politics at the federal level becomes increasingly corrosive and polarized, with trust in Congress and the President at historic lows, Americans still celebrate their cities. And cities are where the action is when it comes to using technology to thicken the mesh of civic goods — more and more cities are using data to animate and inform interactions between government and citizens to improve wellbeing.
Every day, I learn about some new civic improvement that will become possible when we can assume the presence of ubiquitous, cheap, and unlimited data connectivity in cities. Some of these are made possible by the proliferation of smartphones; others rely on the increasing number of internet-connected sensors embedded in the built environment. In both cases, the constant is data. (My new book, The Responsive City, written with co-author Stephen Goldsmith, tells stories from Chicago, Boston, New York City and elsewhere about recent developments along these lines.)
For example, with open fiber networks in place, sending video messages will become as accessible and routine as sending email is now. Take a look at rhinobird.tv, a free lightweight, open-source video service that works in browsers (no special download needed) and allows anyone to create a hashtag-driven “channel” for particular events and places. A debate or protest could be viewed from a thousand perspectives. Elected officials and public employees could easily hold streaming, virtual town hall meetings.
Given all that video and all those livestreams, we’ll need curation and aggregation to make sense of the flow. That’s why visualization norms, still in their infancy, will become a greater part of literacy. When the Internet Archive attempted late last year to “map” 400,000 hours of television news, against worldwide locations, it came up with pulsing blobs of attention. Although visionary Kevin Kelly has been talking about data visualization as a new form of literacy for years, city governments still struggle with presenting complex and changing information in standard, easy-to-consume ways.
Plenar.io is one attempt to resolve this. It’s a platform developed by former Chicago Chief Data Officer Brett Goldstein that allows public datasets to be combined and mapped with easy-to-see relationships among weather and crime, for example, on a single city block. (A sample question anyone can ask of Plenar.io: “Tell me the story of 700 Howard Street in San Francisco.”) Right now, Plenar.io’s visual norm is a map, but it’s easy to imagine other forms of presentation that could become standard. All the city has to do is open up its widely varying datasets…”
