A powerful argument for new laws and policies regarding cyber-security, from the former US Secretary of Homeland Security. The most dangerous threat we-individually and as a society-face today is no longer military, but rather the increasingly pervasive exposure of our personal information; nothing undermines our freedom more than losing control of information about ourselves. And yet, as daily events underscore, we are ever more vulnerable to cyber-attack. In this bracing book, Michael Chertoff makes clear that our laws and policies surrounding the protection of personal information, written for an earlier time, need to be completely overhauled in the Internet era. On the one hand, the collection of data-more widespread by business than by government, and impossible to stop-should be facilitated as an ultimate protection for society. On the other, standards under which information can be inspected, analysed or used must be significantly tightened. In offering his compelling call for action, Chertoff argues that what is at stake is not only the simple loss of privacy, which is almost impossible to protect, but also that of individual autonomy-the ability to make personal choices free of manipulation or coercion. Offering colourful stories over many decades that illuminate the three periods of data gathering we have experienced, Chertoff explains the complex legalities surrounding issues of data collection and dissemination today and charts a forceful new strategy that balances the needs of government, business and individuals alike.

This book addresses the legal feasibility of ethnic data collection and positive action for equality and anti-discrimination purposes, and considers how they could be used to promote the Roma minority's inclusion in Europe. The book's central aim is to research how a societal problem can be improved upon from a legal perspective. The controversy surrounding ethnic data collection and positive action severely limits their use at the national level. Accordingly, legal and political concerns are analysed and addressed in order to demonstrate that it is possible to collect such data and to implement such measures while fully respecting international and European human rights norms, provided that certain conditions are met. Part I focuses on ethnic data collection and explores the key rules and principles that govern it, the ways in which this equality tool could be used, and how potential obstacles might be overcome. It also identifies and addresses the specific challenges that arise when collecting ethnic data on the Roma minority in Europe. In turn, Part II explores positive action and the broad range of measures covered by the concept, before analysing the applicable international and European framework. It reviews the benefits and challenges of implementing positive action for Roma, identifies best practices, and gives special consideration to inter-cultural mediation in the advancement of Roma inclusion. The book concludes with an overview of the main findings on both topics and by identifying three essential elements that must be in place, in addition to full respect for the applicable legal rules, in order to combat discrimination and achieve the inclusion of Roma in Europe by complementing existing anti-discrimination frameworks with the collection of ethnic data and the implementation of positive action schemes.

This book constitutes the proceedings of the International Conference on Web of Services, ICWS 2020, held virtually as part of SCF 2020, in Honolulu, HI, USA, in September 2020. The 14 full papers presented in this volume were carefully reviewed and selected from 52 submissions. The conference proceeding ICWS 2020 presents the latest fundamental advances in the state of the art and practice of Web-based services, identify emerging research topics, and define the future of Web-based services.

This open access book provides the first comprehensive collection of papers that provide an integrative view on cybersecurity. It discusses theories, problems and solutions on the relevant ethical issues involved. This work is sorely needed in a world where cybersecurity has become indispensable to protect trust and confidence in the digital infrastructure whilst respecting fundamental values like equality, fairness, freedom, or privacy. The book has a strong practical focus as it includes case studies outlining ethical issues in cybersecurity and presenting guidelines and other measures to tackle those issues. It is thus not only relevant for academics but also for practitioners in cybersecurity such as providers of security software, governmental CERTs or Chief Security Officers in companies.

This book explores a wide range of topics in digital ethics. It features 11 chapters that analyze the opportunities and the ethical challenges posed by digital innovation, delineate new approaches to solve them, and offer concrete guidance to harness the potential for good of digital technologies. The contributors are all members of the Digital Ethics Lab (the DELab), a research environment that draws on a wide range of academic traditions. The chapters highlight the inherently multidisciplinary nature of the subject, which cannot be separated from the epistemological foundations of the technologies themselves or the political implications of the requisite reforms. Coverage illustrates the importance of expert knowledge in the project of designing new reforms and political systems for the digital age. The contributions also show how this task requires a deep self-understanding of who we are as individuals and as a species. The questions raised here have ancient -- perhaps even timeless -- roots. The phenomena they address may be new. But, the contributors examine the fundamental concepts that undergird them: good and evil, justice and truth. Indeed, every epoch has its great challenges. The role of philosophy must be to redefine the meaning of these concepts in light of the particular challenges it faces. This is true also for the digital age. This book takes an important step towards redefining and re-implementing fundamental ethical concepts to this new era.

How disputes over privacy and security have shaped the relationship between the European Union and the United States and what this means for the future We live in an interconnected world, where security problems like terrorism are spilling across borders, and globalized data networks and e-commerce platforms are reshaping the world economy. This means that states' jurisdictions and rule systems clash. How have they negotiated their differences over freedom and security? Of Privacy and Power investigates how the European Union and United States, the two major regulatory systems in world politics, have regulated privacy and security, and how their agreements and disputes have reshaped the transatlantic relationship. The transatlantic struggle over freedom and security has usually been depicted as a clash between a peace-loving European Union and a belligerent United States. Henry Farrell and Abraham Newman demonstrate how this misses the point. The real dispute was between two transnational coalitions-one favoring security, the other liberty-whose struggles have reshaped the politics of surveillance, e-commerce, and privacy rights. Looking at three large security debates in the period since 9/11, involving Passenger Name Record data, the SWIFT financial messaging controversy, and Edward Snowden's revelations, the authors examine how the powers of border-spanning coalitions have waxed and waned. Globalization has enabled new strategies of action, which security agencies, interior ministries, privacy NGOs, bureaucrats, and other actors exploit as circumstances dictate. The first serious study of how the politics of surveillance has been transformed, Of Privacy and Power offers a fresh view of the role of information and power in a world of economic interdependence.

"Delete" looks at the surprising phenomenon of perfect remembering in the digital age, and reveals why we must reintroduce our capacity to forget. Digital technology empowers us as never before, yet it has unforeseen consequences as well. Potentially humiliating content on Facebook is enshrined in cyberspace for future employers to see. Google remembers everything we've searched for and when. The digital realm remembers what is sometimes better forgotten, and this has profound implications for us all.

In "Delete," Viktor Mayer-Schonberger traces the important role that forgetting has played throughout human history, from the ability to make sound decisions unencumbered by the past to the possibility of second chances. The written word made it possible for humans to remember across generations and time, yet now digital technology and global networks are overriding our natural ability to forget--the past is ever present, ready to be called up at the click of a mouse. Mayer-Schonberger examines the technology that's facilitating the end of forgetting--digitization, cheap storage and easy retrieval, global access, and increasingly powerful software--and describes the dangers of everlasting digital memory, whether it's outdated information taken out of context or compromising photos the Web won't let us forget. He explains why information privacy rights and other fixes can't help us, and proposes an ingeniously simple solution--expiration dates on information--that may.

"Delete" is an eye-opening book that will help us remember how to forget in the digital age."

'Devastating and urgent, this book could not be more timely' Caroline Criado Perez, award-winning and bestselling author of Invisible Women Danielle Citron takes the conversation about technology and privacy out of the boardrooms and op-eds to reach readers where we are - in our bathrooms and bedrooms; with our families and our lovers; in all the parts of our lives we assume are untouchable - and shows us that privacy, as we think we know it, is largely already gone. The boundary that once protected our intimate lives from outside interests is an artefact of the twentieth century. In the twenty-first, we have embraced a vast array of technology that enables constant access and surveillance of the most private aspects of our lives. From non-consensual pornography, to online extortion, to the sale of our data for profit, we are vulnerable to abuse -- and our laws have failed miserably to keep up. With vivid examples drawn from interviews with victims, activists and lawmakers from around the world, The Fight for Privacy reveals the threat we face and argues urgently and forcefully for a reassessment of privacy as a human right. As a legal scholar and expert, Danielle Citron is the perfect person to show us the way to a happier, better protected future.

This open access book answers two central questions: firstly, is it at all possible to verify electronic equipment procured from untrusted vendors? Secondly, can I build trust into my products in such a way that I support verification by untrusting customers? In separate chapters the book takes readers through the state of the art in fields of computer science that can shed light on these questions. In a concluding chapter it discusses realistic ways forward. In discussions on cyber security, there is a tacit assumption that the manufacturer of equipment will collaborate with the user of the equipment to stop third-party wrongdoers. The Snowden files and recent deliberations on the use of Chinese equipment in the critical infrastructures of western countries have changed this. The discourse in both cases revolves around what malevolent manufacturers can do to harm their own customers, and the importance of the matter is on par with questions of national security. This book is of great interest to ICT and security professionals who need a clear understanding of the two questions posed in the subtitle, and to decision-makers in industry, national bodies and nation states.

Using both a theoretical argumentation and an empirical investigation, this book rationalizes the view that in order to understand people's privacy perceptions and behaviors, a situational perspective needs to be adopted. To this end, the book is divided into three parts. Part I advances the theory of situational privacy and self-disclosure by discussing impacts of new information and communication technologies on traditional theories of privacy and self-disclosure. Based on five basic suppositions, it describes three major processes of the theory: pre-situational privacy regulations processes, situational privacy perception and self-disclosure processes, and post-situational evaluation processes. Next, Part II presents the application of the theory to smartphone-based communication. It first analyses how people choose certain communication environments on their smartphones, how they manipulate them, and how these external factors affect self-disclosure within these environments. It then details a multi-method study conducted to test the derived assumptions and discusses the obtained results. Part III reflects on the overall implications of the theory, summarizes the major findings and lastly considers possible extensions and perspectives on future research. Intended mainly for researchers in privacy and communication studies, the book offers privacy scholars a systematic review of both classic and contemporary theories of privacy and self-disclosure. At the same time, communication scholars benefit from an additional methodological discussion of the mobile experience sampling method, which provides an invaluable approach to measuring situational communication processes.

This handbook covers the fundamental principles and theory, and the state-of-the-art research, systems and applications, in the area of mobility data privacy. It is primarily addressed to computer science and statistics researchers and educators, who are interested in topics related to mobility privacy. This handbook will also be valuable to industry developers, as it explains the state-of-the-art algorithms for offering privacy. By discussing a wide range of privacy techniques, providing in-depth coverage of the most important ones, and highlighting promising avenues for future research, this handbook also aims at attracting computer science and statistics students to this interesting field of research. The advances in mobile devices and positioning technologies, together with the progress in spatiotemporal database research, have made possible the tracking of mobile devices (and their human companions) at very high accuracy, while supporting the efficient storage of mobility data in data warehouses, which this handbook illustrates. This has provided the means to collect, store and process mobility data of an unprecedented quantity, quality and timeliness. As ubiquitous computing pervades our society, user mobility data represents a very useful but also extremely sensitive source of information. On one hand, the movement traces that are left behind by the mobile devices of the users can be very useful in a wide spectrum of applications such as urban planning, traffic engineering, and environmental pollution management. On the other hand, the disclosure of mobility data to third parties may severely jeopardize the privacy of the users whose movement is recorded, leading to abuse scenarios such as user tailing and profiling. A significant amount of research work has been conducted in the last 15 years in the area of mobility data privacy and important research directions, such as privacy-preserving mobility data management, privacy in location sensing technologies and location-based services, privacy in vehicular communication networks, privacy in location-based social networks, privacy in participatory sensing systems which this handbook addresses.. This handbook also identifies important privacy gaps in the use of mobility data and has resulted to the adoption of international laws for location privacy protection (e.g., in EU, US, Canada, Australia, New Zealand, Japan, Singapore), as well as to a large number of interesting technologies for privacy-protecting mobility data, some of which have been made available through open-source systems and featured in real-world applications.

The objective of this book is to provide the reader with a comprehensive survey of the topic compressed sensing in information retrieval and signal detection with privacy preserving functionality without compromising the performance of the embedding in terms of accuracy or computational efficiency. The reader is guided in exploring the topic by first establishing a shared knowledge about compressed sensing and how it is used nowadays. Then, clear models and definitions for its use as a cryptosystem and a privacy-preserving embedding are laid down, before tackling state-of-the-art results for both applications. The reader will conclude the book having learned that the current results in terms of security of compressed techniques allow it to be a very promising solution to many practical problems of interest. The book caters to a broad audience among researchers, scientists, or engineers with very diverse backgrounds, having interests in security, cryptography and privacy in information retrieval systems. Accompanying software is made available on the authors' website to reproduce the experiments and techniques presented in the book. The only background required to the reader is a good knowledge of linear algebra, probability and information theory.
