Selected Readings on Blockchain and Identity

Curated on Posted on by Stefaan Verhulst

By Hannah Pierce and Stefaan Verhulst

The Living Library’s Selected Readings series seeks to build a knowledge base on innovative approaches for improving the effectiveness and legitimacy of governance. This curated and annotated collection of recommended works on the topic of blockchain and identity was originally published in 2017.

The potential of blockchain and other distributed ledger technologies to create positive social change has inspired enthusiasm, broad experimentation, and some skepticism. In this edition of the Selected Readings series, we explore and curate the literature on blockchain and how it impacts identity as a means to access services and rights. (In a previous edition we considered the Potential of Blockchain for Transforming Governance).

Introduction

In 2008, an unknown source calling itself Satoshi Nakamoto released a paper named Bitcoin: A Peer-to-Peer Electronic Cash System which introduced Blockchain. Blockchain is a novel technology that uses a distributed ledger to record transactions and ensure compliance. Blockchain and other Distributed Ledger technologies (DLTs) rely on an ability to act as a vast, transparent, and secure public database.

Distributed ledger technologies (DLTs) have disruptive potential beyond innovation in products, services, revenue streams and operating systems within industry. By providing transparency and accountability in new and distributed ways, DLTs have the potential to positively empower underserved populations in myriad ways, including providing a means for establishing a trusted digital identity.

Consider the potential of DLTs for 2.4 billion people worldwide, about 1.5 billion of whom are over the age of 14, who are unable to prove identity to the satisfaction of authorities and other organizations – often excluding them from property ownership, free movement, and social protection as a result. At the same time, transition to a DLT led system of ID management involves various risks, that if not understood and mitigated properly, could harm potential beneficiaries.

Annotated Selected Reading List

Governance

Cuomo, Jerry, Richard Nash, Veena Pureswaran, Alan Thurlow, Dave Zaharchuk. “Building trust in government: Exploring the potential of blockchains.” IBM Institute for Business Value. January 2017.

This paper from the IBM Institute for Business Value culls findings from surveys conducted with over 200 government leaders in 16 countries regarding their experiences and expectations for blockchain technology. The report also identifies “Trailblazers”, or governments that expect to have blockchain technology in place by the end of the year, and details the views and approaches that these early adopters are taking to ensure the success of blockchain in governance. These Trailblazers also believe that there will be high yields from utilizing blockchain in identity management and that citizen services, such as voting, tax collection and land registration, will become increasingly dependent upon decentralized and secure identity management systems. Additionally, some of the Trailblazers are exploring blockchain application in borderless services, like cross-province or state tax collection, because the technology removes the need for intermediaries like notaries or lawyers to verify identities and the authenticity of transactions.

Mattila, Juri. “The Blockchain Phenomenon: The Disruptive Potential of Distributed Consensus Architectures.” Berkeley Roundtable on the International Economy. May 2016.

This working paper gives a clear introduction to blockchain terminology, architecture, challenges, applications (including use cases), and implications for digital trust, disintermediation, democratizing the supply chain, an automated economy, and the reconfiguration of regulatory capacity. As far as identification management is concerned, Mattila argues that blockchain can remove the need to go through a trusted third party (such as a bank) to verify identity online. This could strengthen the security of personal data, as the move from a centralized intermediary to a decentralized network lowers the risk of a mass data security breach. In addition, using blockchain technology for identity verification allows for a more standardized documentation of identity which can be used across platforms and services. In light of these potential capabilities, Mattila addresses the disruptive power of blockchain technology on intermediary businesses and regulating bodies.

Identity Management Applications

Allen, Christopher.  “The Path to Self-Sovereign Identity.” Coindesk. April 27, 2016.

In this Coindesk article, author Christopher Allen lays out the history of digital identities, then explains a concept of a “self-sovereign” identity, where trust is enabled without compromising individual privacy. His ten principles for self-sovereign identity (Existence, Control, Access, Transparency, Persistence, Portability, Interoperability, Consent, Minimization, and Protection) lend themselves to blockchain technology for administration. Although there are actors making moves toward the establishment of self-sovereign identity, there are a few challenges that face the widespread implementation of these tenets, including legal risks, confidentiality issues, immature technology, and a reluctance to change established processes.

Jacobovitz, Ori. “Blockchain for Identity Management.” Department of Computer Science, Ben-Gurion University. December 11, 2016.

This technical report discusses advantages of blockchain technology in managing and authenticating identities online, such as the ability for individuals to create and manage their own online identities, which offers greater control over access to personal data. Using blockchain for identity verification can also afford the potential of “digital watermarks” that could be assigned to each of an individual’s transactions, as well as negating the creation of unique usernames and passwords online. After arguing that this decentralized model will allow individuals to manage data on their own terms, Jacobvitz provides a list of companies, projects, and movements that are using blockchain for identity management.

Mainelli, Michael. “Blockchain Will Help Us Prove Our Identities in a Digital World.” Harvard Business Review. March 16, 2017.

In this Harvard Business Review article, author Michael Mainelli highlights a solution to identity problems for rich and poor alike–mutual distributed ledgers (MDLs), or blockchain technology. These multi-organizational data bases with unalterable ledgers and a “super audit trail” have three parties that deal with digital document exchanges: subjects are individuals or assets, certifiers are are organizations that verify identity, and inquisitors are entities that conducts know-your-customer (KYC) checks on the subject. This system will allow for a low-cost, secure, and global method of proving identity. After outlining some of the other benefits that this technology may have in creating secure and easily auditable digital documents, such as greater tolerance that comes from viewing widely public ledgers, Mainelli questions if these capabilities will turn out to be a boon or a burden to bureaucracy and societal behavior.

Personal Data Security Applications

Banafa, Ahmed. “How to Secure the Internet of Things (IoT) with Blockchain.” Datafloq. August 15, 2016.

This article details the data security risks that are coming up as the Internet of Things continues to expand, and how using blockchain technology can protect the personal data and identity information that is exchanged between devices. Banafa argues that, as the creation and collection of data is central to the functions of Internet of Things devices, there is an increasing need to better secure data that largely confidential and often personally identifiable. Decentralizing IoT networks, then securing their communications with blockchain can allow to remain scalable, private, and reliable. Enabling blockchain’s peer-to-peer, trustless communication may also enable smart devices to initiate personal data exchanges like financial transactions, as centralized authorities or intermediaries will not be necessary.

Shrier, David, Weige Wu and Alex Pentland. “Blockchain & Infrastructure (Identity, Data Security).” Massachusetts Institute of Technology. May 17, 2016.

This paper, the third of a four-part series on potential blockchain applications, covers the potential of blockchains to change the status quo of identity authentication systems, privacy protection, transaction monitoring, ownership rights, and data security. The paper also posits that, as personal data becomes more and more valuable, that we should move towards a “New Deal on Data” which provides individuals data protection–through blockchain technology– and the option to contribute their data to aggregates that work towards the common good. In order to achieve this New Deal on Data, robust regulatory standards and financial incentives must be provided to entice individuals to share their data to benefit society.

A Better Way to Trace Scattered Refugees

Curated on Posted on by Stefaan Verhulst

Tina Rosenberg in The New York Times: “…No one knew where his family had gone. Then an African refugee in Ottawa told him about Refunite. He went on its website and opened an account. He gave his name, phone number and place of origin, and listed family members he was searching for.

Three-quarters of a century ago, while World War II still raged, the Allies created the International Tracing Service to help the millions who had fled their homes. Its central name index grew to 50 million cards, with information on 17.5 million individuals. The index still exists — and still gets queries — today.

Index cards have become digital databases, of course. And some agencies have brought tracing into the digital age in other ways. Unicef, for example, equips staff during humanitarian emergencies with a software called Primero, which helps them get children food, medical care and other help — and register information about unaccompanied children. A parent searching for a child can register as well. An algorithm makes the connection — “like a date-finder or matchmaker,” said Robert MacTavish, who leads the Primero project.

Most United Nations agencies rely for family tracing on the International Committee of the Red Cross, the global network of national Red Cross and Red Crescent societies. Florence Anselmo, who directs the I.C.R.C.’s Central Tracing Agency, said that the I.C.R.C. and United Nations agencies can’t look in one another’s databases. That’s necessary for privacy reasons, but it’s an obstacle to family tracing.

Another problem: Online databases allow the displaced to do their own searches. But the I.C.R.C. has these for only a few emergency situations. Anselmo said that most tracing is done by the staff of national Red Cross societies, who respond to requests from other countries. But there is no global database, so people looking for loved ones must guess which countries to search.

The organization is working on developing an algorithm for matching, but for now, the search engines are human. “When we talk about tracing, it’s not only about data matching,” Anselmo said. “There’s a whole part about accompanying families: the human aspect, professionals as well as volunteers who are able to look for people — even go house to house if needed.”

This is the mom-and-pop general store model of tracing: The customer makes a request at the counter, then a shopkeeper with knowledge of her goods and a kind smile goes to the back and brings it out, throwing in a lollipop. But the world has 65 million forcibly displaced people, a record number. Personalized help to choose from limited stock is appropriate in many cases. But it cannot possibly be enough.

Refunite seeks to become the eBay of family tracing….(More)”

UN Opens New Office to Monitor AI Development and Predict Possible Threats

Curated on Posted on by Stefaan Verhulst

Interesting Engineering: “The United Nations has created a new office in the Netherlands dedicated to the monitoring and research of Artificial Intelligence (AI) technologies. The new office will collect information about the way in which AI is impacting the world. Researchers will have a particular focus on the way AI relates to global security but will also monitor the effects of job loss from AI and automation.

Irakli Beridze, a UN senior strategic adviser will head the office. They have described the new office saying, “A number of UN organisations operate projects involving robots and AI, such as the group of experts studying the role of autonomous military robots in the realm of conventional weapons. These are temporary measures. Ours is the first permanent UN office on this subject. We are looking at the risks as well as the advantages.”….He suggests that the speed of AI technology development is of primary concern. He explains, “This can make for instability if society does not adapt quickly enough. One of our most important tasks is to set up a network of experts from business, knowledge institutes, civil society organisations and governments. We certainly do not want to plead for a ban or a brake on technologies. We will also explore how new technology can contribute to the sustainable development goals of the UN. For this, we want to start concrete projects. We will not be a talking club.”…(More).

Google Gets Serious About Mapping Wheelchair Accessibility

Curated on Posted on by Stefaan Verhulst
Linda Poon at CityLab: “If there’s one thing Google’s got at its disposal, it’s a global army of avid map users. Now the company is leveraging that power to make its Maps feature more useful for people with mobility challenges—a group that often gets overlooked in the world of transit and urban innovation.

Google Maps already indicates if a location is wheelchair accessible—a result of a personal project by one of its employees—but its latest campaign will crowdsource data from its 30 million Local Guides worldwide, who contribute tips and photos about neighborhood establishments in exchange for points and small prizes like extra digital storage space. The company is calling on them to answer five simple questions—like whether a building has accessible entrances or bathrooms—when they submit a review for a location. In the coming weeks, Google will host workshops and “geowalks” specifically focused on mobility across seven cities, from New York City and London to Tokyo and Surabaya, Indonesia.

“The [users] have multiple motivations, and one is wanting to help their own community get around.” says Laura Slabin, Google’s director of local content and community. “So we’re leveraging the fact that people are motivated by altruism.”

But as simple as the questions seem—Is there wheelchair-accessible seating? or Is there a wheelchair-accessible elevator?—answering them requires careful attention to detail. That’s why Google even sent out a  nifty tip sheet to help its physically abled members answer those questions….(More)”.

How Blockchain Is Kickstarting the Financial Lives of Refugees

Curated on Posted on by Stefaan Verhulst

Mike Orcutt at MIT Technology Review: “Finland’s digital money system for asylum seekers shows what blockchain technology can offer the unbanked….

For a refugee in a new country, identity—at least in the official sense—can be among the hardest things to recover. And without an official ID it is nearly impossible to advance in society.

Finland, which like many European nations has recently seen a large influx of asylum seekers, is using a cryptographic ledger called blockchain to help them get on their feet faster.

For two years the Finnish Immigration Service has been giving asylum seekers who don’t have bank accounts prepaid Mastercards instead of the traditional cash disbursements, and today the program has several thousand active cardholders. Developed by the Helsinki-based startup MONI, the card is also linked to a unique digital identity stored on a blockchain, the same technology that underpins the digital currency Bitcoin.

Bitcoin has demonstrated how blockchain technology can be used to transmit value between individuals without the need for corporate middlemen. Core to the technology is a software protocol that creates a permanent record of every single Bitcoin transaction. Anyone can access this record, called the blockchain, by downloading the Bitcoin software. Computers running the software all over the world maintain the blockchain, and use it to verify new transactions.

Blockchains are seen as a promising avenue for opening new financial opportunities to people who don’t have access to modern financial services. Besides eliminating the need for a traditional financial institution to mediate transactions, they provide a means for creating and securely storing a digital form of identification that can’t be corrupted and is easily accessible from anywhere….

In Finland, a MONI card can help address several challenges facing asylum seekers, says Jouko Salonen, director of the Finnish Immigration Service. Most importantly, a MONI account functions like a bank account, removing a major barrier to gaining employment. People can use their accounts to buy things, pay bills, and even receive direct deposits from employers. Meanwhile, every transaction is recorded in a public, virtually incorruptible database maintained by a decentralized global network of computers. That enables the Immigration Service to keep track of the cardholders and their spending….(More)”

Internet of Things tackles global animal poaching

Curated on Posted on by Stefaan Verhulst

Springwise: “ZSL (Zoological Society of London), one of the most famous zoos in Europe, has teamed up with non-profit technology company Digital Catapult to support the development of anti-poaching technology. The partnership will use the Internet of Things (IoT) and Low Power Wide Area Network (LPWAN) technologies to create a sensor and satellite-enabled network that will be able to help conservationists monitor wildlife and respond to poaching threats on land and sea in some of the world’s most remote national parks.

Up to 35,000 African elephants were killed by poachers in 2016, and black rhino and mountain gorilla populations continue to be at high risk. LPWAN could help prevent poaching in game reserves by enabling remote sensors to communicate with one another over long distance while using only a small amount of power. These connected sensors are able to detect activities nearby and determine whether these originate from wildlife or poachers, creating immediate alerts for those monitoring the area.

Digital Catapult has installed a LPWAN base station at the ZSL headquarters at London Zoo, which will enable prototypes to be tested on site. This technology will build on the revolutionary work already underway in areas including Kenya, Nepal, Australia, the Chagos Archipelago, and Antarctica.

The practise of poaching has been the target of many technology companies, with a similar project using artificial intelligence to monitor poachers recently coming to light. One of the many devastating impacts of poaching is the potential to cause extinction of some animals, and one startup has tackled this potential catastrophe with rhinos by producing a 3D printed horn that could help the species avoid being a target….(More)”.

Want to make your vote really count? Stick a blockchain on it

Curated on Posted on by Stefaan Verhulst

Niall Firth at New Scientist: “Bitcoin changed the way we think about money forever. Now a type of political cryptocurrency wants to do the same for votes, reinventing how we participate in democracy.

Sovereign is being unveiled this week by Democracy Earth, a not-for-profit organisation in Palo Alto, California. It combines liquid democracy – which gives individuals more flexibility in how they use their votes – with blockchains, digital ledgers of transactions that keep cryptocurrencies like bitcoin secure. Sovereign’s developers hope it could signal the beginning of a democratic system that transcends national borders.

“There’s an intrinsic incompatibility between the internet and nation states,” says Santiago Siri, one of Democracy Earth’s co-founders. “If we’re going to think about digital governance, we need to think in a borderless, global way.”

 The basic concept of liquid democracy is that voters can express their wishes on an issue directly or delegate their vote to someone else they think is better-placed to decide on their behalf. In turn, those delegates can also pass those votes upwards through the chain. Crucially, users can see how their delegate voted and reclaim their vote to use themselves.

It’s an attractive concept, but it hasn’t been without problems. One is that a seemingly unending series of votes saps the motivation of users, so fewer votes are cast over time. Additionally, a few “celebrities” can garner an unhealthy number of delegated votes and wield too much power – an issue Germany’s Pirate Party ran into when experimenting with liquid democracy.

Siri thinks Sovereign can solve both of these problems. It sits on existing blockchain software platforms, such as Ethereum, but instead of producing units of cryptocurrency, Sovereign creates a finite number of tokens called “votes”. These are assigned to registered users who can vote as part of organisations who set themselves up on the network, whether that is a political party, a municipality, a country or even a co-operatively run company.

No knowledge of blockchains is required – voters simply use an app. Votes are then “dripped” into their accounts over time like a universal basic income of votes. Users can debate with each other before deciding which way to vote. A single vote takes just a tap, while more votes can be assigned to a single issue using a slider bar….(More)”

Harnessing the Data Revolution to Achieve the Sustainable Development Goals

Curated on Posted on by Stefaan Verhulst
Erol Yayboke et al at CSIS: “Functioning societies collect accurate data and utilize the evidence to inform policy. The use of evidence derived from data in policymaking requires the capability to collect and analyze accurate data, clear administrative channels through which timely evidence is made available to decisionmakers, and the political will to rely on—and ideally share—the evidence. The collection of accurate and timely data, especially in the developing world, is often logistically difficult, not politically expedient, and/or expensive.

Before launching its second round of global goals—the Sustainable Development Goals (SDGs)—the United Nations convened a High-Level Panel of Eminent Persons on the Post-2015 Development Agenda. As part of its final report, the Panel called for a “data revolution” and recommended the formation of an independent body to lead the charge.1The report resulted in the creation of the Global Partnership for Sustainable Development Data (GPSDD)—an independent group of countries, companies, data communities, and NGOs—and the SDG Data Labs, a private initiative partnered with the GPSDD. In doing so the United Nations and its partners signaled broad interest in data and evidence-based policymaking at a high level. In fact, the GPSDD calls for the “revolution in data” by addressing the “crisis of non-existent, inaccessible or unreliable data.”2 As this report shows, this is easier said than done.

This report defines the data revolution as an unprecedented increase in the volume and types of data—and the subsequent demand for them—thanks to the ongoing yet uneven proliferation of new technologies. This revolution is allowing governments, companies, researchers, and citizens to monitor progress and drive action, often with real-time, dynamic, disaggregated data. Much work will be needed to make sure the data revolution reaches developing countries facing difficult challenges (i.e., before the data revolution fully becomes the data revolution for sustainable development). It is important to think of the revolution as a multistep process, beginning with building basic knowledge and awareness of the value of data. This is followed by a more specific focus on public private partnerships, opportunities, and constraints regarding collection and utilization of data for evidence-based policy decisions….

This report provides the following recommendations to the international community to play a constructive role in the data revolution:

  • Don’t fixate on big data alone. Focus on the foundation necessary to facilitate leapfrogs around all types of data: small, big, and everywhere in between.
  • Increase funding for capacity building as part of an expansion of broader educational development priorities.
  • Highlight, share, and support enlightened government-driven approaches to data.
  • Increase funding for the data revolution and coordinate donor efforts.
  • Coordinate UN data revolution-related activities closely with an expanded GPSDD.
  • Secure consensus on data sharing, ownership, and privacy-related international standards….(More)”.

Patient Power: Crowdsourcing in Cancer

Curated on Posted on by Stefaan Verhulst

Bonnie J. Addario at the HuffPost: “…Understanding how to manage and manipulate vast sums of medical data to improve research and treatments has become a top priority in the cancer enterprise. Researchers at the University of North Carolina Chapel Hill are using IBM’s Watson and its artificial intelligence computing power to great effect. Dr. Norman Sharpless told Charlie Rose from CBS’ 60 Minutes that Watson is reading tens of millions of medical papers weekly (8,000 new cancer research papers are published every day) and regularly scanning the web for new clinical trials most people, including researchers, are unaware of. The task is “essentially undoable” he said, for even the best, well-informed experts.

UNC’s effort is truly wonderful albeit a macro approach, less tailored and accessible only to certain medical centers. My experience tells me what the real problem is: How does a patient newly diagnosed with lung cancer, fragile and scared find the most relevant information without being overwhelmed and giving up? If the experts can’t easily find key data without Watson’s help, and Google’s first try turns up millions upon millions of semi-useful results, how do we build hope that there are good online answers for our patients?

We’ve thought about this a lot at the Addario Lung Cancer Foundation and figured out that the answer lies with the patients themselves. Why not crowdsource it with people who have lung cancer, their caregivers and family members?

So, we created the first-ever global Lung Cancer Patient Registry that simplifies the collection, management and distribution of critical health-related information – all in one place so that researchers and patients can easily access and find data specific to lung cancer patients.

This is a data-rich environment for those focusing solely on finding a cure for lung cancer. And it gives patients access to other patients to compare notes and generally feel safe sharing intimate details with their peers….(More)”

Civic Tech in the Global South

Curated on Posted on by Stefaan Verhulst

New book edited by Tiago Peixoto: “Civic Tech in the Global South is comprised of one study and three field evaluations of civic tech initiatives in developing countries. The study reviews evidence on the use of 23 digital platforms designed to amplify citizen voices to improve service delivery, highlighting citizen uptake and the degree of responsiveness by public service providers. The initiatives are an SMS-based polling platform run by UNICEF in Uganda, a complaints-management system run by the water sector in Kenya, and an internet-based participatory budgeting program in Brazil. Based on these experiences, the authors examine: i) the extent to which technologies have promoted inclusiveness, ii) the effect of these initiatives on public service delivery, and iii) the extent to which these effects can be attributed to technology….(More)”.
