This book introduces the state-of-the-art algorithms for data and computation privacy. It mainly focuses on searchable symmetric encryption algorithms and privacy preserving multi-party computation algorithms. This book also introduces algorithms for breaking privacy, and gives intuition on how to design algorithm to counter privacy attacks. Some well-designed differential privacy algorithms are also included in this book. Driven by lower cost, higher reliability, better performance, and faster deployment, data and computing services are increasingly outsourced to clouds. In this computing paradigm, one often has to store privacy sensitive data at parties, that cannot fully trust and perform privacy sensitive computation with parties that again cannot fully trust. For both scenarios, preserving data privacy and computation privacy is extremely important. After the Facebook-Cambridge Analytical data scandal and the implementation of the General Data Protection Regulation by European Union, users are becoming more privacy aware and more concerned with their privacy in this digital world. This book targets database engineers, cloud computing engineers and researchers working in this field. Advanced-level students studying computer science and electrical engineering will also find this book useful as a reference or secondary text.

This book revises the strategic objectives of Information Warfare, interpreting them according to the modern canons of information age, focusing on the fabric of society, the economy, and critical Infrastructures. The authors build plausible detailed real-world scenarios for each entity, showing the related possible threats from the Information Warfare point of view. In addition, the authors dive into the description of the still open problems, especially when it comes to critical infrastructures, and the countermeasures that can be implemented, possibly inspiring further research in the domain. This book intends to provide a conceptual framework and a methodological guide, enriched with vivid and compelling use cases for the readers (e.g. technologists, academicians, military, government) interested in what Information Warfare really means, when its lenses are applied to current technology. Without sacrificing accuracy, rigor and, most importantly, the big picture of Information Warfare, this book dives into several relevant and up-to-date critical domains. The authors illustrate how finance (an always green target of Information Warfare) is intertwined with Social Media, and how an opponent could exploit these latter ones to reach its objectives. Also, how cryptocurrencies are going to reshape the economy, and the risks involved by this paradigm shift. Even more compelling is how the very fabric of society is going to be reshaped by technology, for instance how our democratic elections are exposed to risks that are even greater than what appears in the current public discussions. Not to mention how our Critical Infrastructure is becoming exposed to a series of novel threats, ranging from state-supported malware to drones. A detailed discussion of possible countermeasures and what the open issues are for each of the highlighted threats complete this book. This book targets a widespread audience that includes researchers and advanced level students studying and working in computer science with a focus on security. Military officers, government officials and professionals working in this field will also find this book useful as a reference.

For a one-semester undergraduate-level course in Cryptology, Mathematics, or Computer Science.

Designed for either the intelligent freshman (good at math) or for a low-level junior year first course, Cryptology introduces a wide range of up-to-date cryptological concepts along with the mathematical ideas that are behind them. The new and old are organized around a historical framework. A variety of mathematical topics that are germane to cryptology (e.g., modular arithmetic, Boolean functions, complexity theory, etc.) are developed, but they do not overshadow the main focus of the text. Unlike other texts in this field, Cryptology brings students directly to concepts of classical substitutions and transpositions and issues in modern cryptographic methods.

This book provides modern technical answers to the legal requirements of pseudonymisation as recommended by privacy legislation. It covers topics such as modern regulatory frameworks for sharing and linking sensitive information, concepts and algorithms for privacy-preserving record linkage and their computational aspects, practical considerations such as dealing with dirty and missing data, as well as privacy, risk, and performance assessment measures. Existing techniques for privacy-preserving record linkage are evaluated empirically and real-world application examples that scale to population sizes are described. The book also includes pointers to freely available software tools, benchmark data sets, and tools to generate synthetic data that can be used to test and evaluate linkage techniques. This book consists of fourteen chapters grouped into four parts, and two appendices. The first part introduces the reader to the topic of linking sensitive data, the second part covers methods and techniques to link such data, the third part discusses aspects of practical importance, and the fourth part provides an outlook of future challenges and open research problems relevant to linking sensitive databases. The appendices provide pointers and describe freely available, open-source software systems that allow the linkage of sensitive data, and provide further details about the evaluations presented. A companion Web site at https://dmm.anu.edu.au/lsdbook2020 provides additional material and Python programs used in the book. This book is mainly written for applied scientists, researchers, and advanced practitioners in governments, industry, and universities who are concerned with developing, implementing, and deploying systems and tools to share sensitive information in administrative, commercial, or medical databases. The Book describes how linkage methods work and how to evaluate their performance. It covers all the major concepts and methods and also discusses practical matters such as computational efficiency, which are critical if the methods are to be used in practice - and it does all this in a highly accessible way!David J. Hand, Imperial College, London

We have created the ultimate hive-mind robot: an Internet of interconnected devices that senses, thinks and acts. Bruce Schneier calls it the "World-Sized Web". It includes everything from driverless cars to smart thermostats, from billboards that respond to specific people to drones equipped with their own behavioural algorithms. While the World-Sized Web carries enormous potential, Schneier argues that we are unprepared for the vulnerabilities it brings. Cutting-edge digital attackers can now crash your car, pacemaker and home security system and everyone else's. Click Here to Kill Everybody explores the risks and security implications of the World-Sized Web and lays out common-sense policies that will allow us to enjoy the benefits of this new omnipotent age without surrendering ourselves entirely to our creation.

The tension between freedom of expression and European personal data protection regulation is unmistakable. Nowhere is this more apparent than in its interface with professional journalism and other traditional publishers including artists, writers and academics. This book systematically explores how that tension has been managed across thirty-one European States from the 1970s through to the 2010s including under the General Data Protection Regulation (GDPR). It is found that, notwithstanding confusing laws, data authorities have regulated journalism through contextual rights balancing. However, they have struggled to establish a clear standard of strictness or ensure consistent enforcement. Their stance regarding other publishers has been more confused - whilst academics have been subject to onerous restrictions developed for medical and related research, other writers and artists have been largely ignored. This book suggests that contextual rights balancing should be extended to all traditional publishers and systematically developed through robust co-regulation that draws on the strength of both statutory control and self-regulation.

Questions of privacy are critical to the study of contemporary media and society. When we're more and more connected to devices and to content, it's increasingly important to understand how information about ourselves is being collected, transmitted, processed, and mediated. Privacy and the Media equips students to do just that, providing a comprehensive overview of both the theory and reality of privacy and the media in the 21st Century. Offering a rich overview of this crucial and topical relationship, Andy McStay: Explores the foundational topics of journalism, the Snowden leaks, and encryption by companies such as Apple Considers commercial applications including behavioural advertising, big data, algorithms, and the role of platforms such as Google and Facebook Introduces the role of the body with discussions of emotion, wearable media, peer-based privacy, and sexting Encourages students to put their understanding to work with suggestions for further research, challenging them to explore how privacy functions in practice. Privacy and the Media is not a polemic on privacy as 'good' or 'bad', but a call to assess the detail and the potential implications of contemporary media technologies and practices. It is essential reading for students and researchers of digital media, social media, digital politics, and the creative and cultural industries. 'Privacy and the Media is a thoughtful survey of the privacy landscape. McStay reviews the intricate tensions and seeming contradictions to offer an accessible book for anyone curious about the contemporary debates in privacy.' - danah boyd, author of It's Complicated and founder of Data & Society 'McStay's great achievement here is to confront many of the pertinent and complex questions about media and privacy in a style that is both authoritative and easy to read... His book will prove an excellent companion for all students of this fascinating and crucial topic.' - Mireille Hildebrandt, Vrije Universiteit Brussel 'Clearly and accessibly written, this book is a great resource for anyone interested in the broad range of ways in which privacy and contemporary media are entangled and in the big picture of privacy/media relations today... I will definitely be assigning it for my students.' - Helen Kennedy, University of Sheffield

Security is the number one concern for businesses worldwide. The gold standard for attaining security is cryptography because it provides the most reliable tools for storing or transmitting digital information. Written by Niels Ferguson, lead cryptographer for Counterpane, Bruce Schneier's security company, and Bruce Schneier himself, this is the much anticipated follow-up book to Schneier's seminal encyclopedic reference, Applied Cryptography, Second Edition (0-471-11709-9), which has sold more than 150,000 copies.
Niels Ferguson (Amsterdam, Netherlands) is a cryptographic engineer and consultant at Counterpane Internet Security. He has extensive experience in the creation and design of security algorithms, protocols, and multinational security infrastructures. Previously, Ferguson was a cryptographer for DigiCash and CWI. At CWI he developed the first generation of off-line payment protocols. He has published numerous scientific papers.
Bruce Schneier (Minneapolis, MN) is Founder and Chief Technical Officer at Counterpane Internet Security, a managed-security monitoring company. He is also the author of Secrets and Lies: Digital Security in a Networked World (0-471-25311-1).

This book outlines the legal powers of a major Western nation - Australia - to collect and use location information. Mobile service and social media service providers now have the ability to track, record and store more precise location information. Unlike 4G, 5G mobile communications require that cell towers and antennas be in much closer proximity; as a result, the location data can reveal more personal and sensitive information about individual citizens. Despite this aspect, service providers are required to disclose the data to the authorities, without the need for a judicial warrant. This book was written from the perspective of big location data software analytics, a capability that makes it possible to combine various location data points to create a profile on a given individual's movements, habits, and political, religious and ideological orientation. In this regard, privacy is poorly protected. The rationale used to justify the powers was enforcing serious crimes - terrorism offences. Location data can now be retained for at least two years and be collected to investigate even minor offences. This can be done without the person being reasonably suspected of a criminal offence - when the individual is simply determined to be a person of interest. This poses legal risks to vulnerable communities. And yet, such investigative techniques are deemed lawful and reasonable. At a time when national security is so broadly defined to include economic issues, which in turn overlap with climate change and environmental protection, these legal powers should be reassessed. The book clarifies the complex rules that every citizen must know in order to have agency. Further, it calls upon authorities to reflect and to self-regulate, by making the conscious decision to surrender some of their powers to review by the independent judiciary. Without the requirement for a judicial warrant or judicial review, the powers are unfairly broad. The book pursues an interdisciplinary approach to assess the functionality of mobile telecommunications in direct relation to law enforcement powers and existing judicial precedents. Further, it offers a unifying techno-legal perspective on a complex issue touching on modern privacy law and communications technologies.

According to the FBI, about 4000 ransomware attacks happen every day. In the United States alone, victims lost $209 million to ransomware in the first quarter of 2016. Even worse is the threat to critical infrastructure, as seen by the malware infections at electrical distribution companies in Ukraine that caused outages to 225,000 customers in late 2015. Further, recent reports on the Russian hacks into the Democratic National Committee and subsequent release of emails in a coercive campaign to apparently influence the U.S. Presidential Election have brought national attention to the inadequacy of cyber deterrence. The U.S. government seems incapable of creating an adequate strategy to alter the behavior of the wide variety of malicious actors seeking to inflict harm or damage through cyberspace. This book offers a systematic analysis of the various existing strategic cyber deterrence options and introduces the alternative strategy of active cyber defense. It examines the array of malicious actors operating in the domain, their methods of attack, and their motivations. It also provides answers on what is being done, and what could be done, by the government and industry to convince malicious actors that their attacks will not succeed and that risk of repercussions exists. Traditional deterrence strategies of retaliation, denial and entanglement appear to lack the necessary conditions of capability, credibly, and communications due to these malicious actors' advantages in cyberspace. In response, the book offers the option of adopting a strategy of active cyber defense that combines internal systemic resilience to halt cyber attack progress with external disruption capacities to thwart malicious actors' objectives. It shows how active cyber defense is technically capable and legally viable as an alternative strategy for the deterrence of cyber attacks.

Cypherpunk Ethics explores the moral worldview of the cypherpunks, a movement that advocates the use of strong digital cryptography-or crypto, for short-to defend individual privacy and promote institutional transparency in the digital age. Focusing on the writings of Timothy May and Julian Assange, two of the most prolific and influential cypherpunks, the book examines two competing paradigms of cypherpunk philosophy-crypto anarchy and crypto justice-and examines the implications of cypherpunk ethics for a range of contemporary moral issues, including surveillance, privacy, whistleblowing, cryptocurrencies, journalism, democracy, censorship, intellectual property, and power. Rooted in theory but with very real applications, this volume will appeal not only to students and scholars of digital media, communication, journalism, philosophy, political science, critical data studies, sociology, and the history of technology but also to technologists and activists around the world.

This book discusses the main legal and economic challenges to the creation and enforcement of security rights in intellectual property and explores possible avenues of reform, such as more specific rules for security in IP rights and better coordination between intellectual property law and secured transactions law. In the context of business financing, intellectual property rights are still only reluctantly used as collateral, and on a small scale. If they are used at all, it is mostly done in the form of a floating charge or some other "all-asset" security right. The only sector in which security rights in intellectual property play a major role, at least in some jurisdictions, is the financing of movies. On the other hand, it is virtually undisputed that security rights in intellectual property could be economically valuable, or even crucial, for small and medium-sized enterprises - especially for start-ups, which are often very innovative and creative, but have limited access to corporate financing and must rely on capital markets (securitization, capital market). Therefore, they need to secure bank loans, yet lack their own traditional collateral, such as land.

Privacy: Algorithms and Society focuses on encryption technologies and privacy debates in journalistic crypto-cultures, countersurveillance technologies, digital advertising, and cellular location data. Important questions are raised such as: How much information will we be allowed to keep private through the use of encryption on our computational devices? What rights do we have to secure and personalized channels of communication, and how should those be balanced by the state's interests in maintaining order and degrading the capacity of criminals and rival state actors to organize through data channels? What new regimes may be required for states to conduct digital searches, and how does encryption act as countersurveillance? How have key debates relied on racialized social constructions in their discourse? What transformations in journalistic media and practices have occurred with the development of encryption tools? How are the digital footprints of consumers tracked and targeted? Scholars and students from many backgrounds as well as policy makers, journalists, and the general reading public will find a multidisciplinary approach to questions of privacy and encryption encompassing research from Communication, Sociology, Critical Data Studies, and Advertising and Public Relations.

This book examines how face recognition technology is affecting privacy and confidentiality in an era of enhanced surveillance. Further, it offers a new approach to the complex issues of privacy and confidentiality, by drawing on Joseph K in Kafka's disturbing novel The Trial, and on Isaiah Berlin's notion of liberty and freedom. Taking into consideration rights and wrongs, protection from harm associated with compulsory visibility, and the need for effective data protection law, the author promotes ethical practices by reinterpreting privacy as a property right. To protect this right, the author advocates the licensing of personal identifiable images where appropriate. The book reviews American, UK and European case law concerning privacy and confidentiality, the effect each case has had on the developing jurisprudence, and the ethical issues involved. As such, it offers a valuable resource for students of ethico-legal fields, professionals specialising in image rights law, policy-makers, and liberty advocates and activists.

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.

This contributed volume discusses diverse topics to demystify the rapidly emerging and evolving blockchain technology, the emergence of integrated platforms and hosted third-party tools, and the development of decentralized applications for various business domains. It presents various applications that are helpful for research scholars and scientists who are working toward identifying and pinpointing the potential of as well as the hindrances to this technology.

In this collection of essays that represent original and interdisciplinary work, respected scholars address a number of privacy issues. These include how governmental and private sectors develop and deploy technologies that can pose serious compromises to the privacy of individuals and groups; how information and communication system designs pose threats to privacy; how we manage private concerns (child care, job leave, and identity) as public issues amenable to political action and shared awareness; and the fundamental asymmetry of power that exists between individuals and small groups on the one hand and large governmental and corporate entities on the other. Arranged in three sections law and policy; information technology; and information studies, history, and sociology Privacy in America: Interdisciplinary Perspectives will be useful to scholars, practitioners, and students in a variety of fields, including information science, library science, and information systems.

Electronic information networks offer extraordinary advantages to business, government, and individuals in terms of power, capacity, speed, accessibility, and cost. But these same capabilities present substantial privacy issues. With an unprecedented amount of data available in digital format--which is easier and less expensive to access, manipulate, and store--others know more about you than ever before.

Consider this: data routinely collected about you includes your health, credit, marital, educational, and employment histories; the times and telephone numbers of every call you make and receive; the magazines you subscribe to and the books your borrow from the library; your cash withdrawals; your purchases by credit card or check; your electronic mail and telephone messages; where you go on the World Wide Web. The ramifications of such a readily accessible storehouse of information are astonishing.

Governments have responded to these new challenges to personal privacy in a wide variety of ways. At one extreme, the European Union in 1995 enacted sweeping regulation to protect personal information; at the other extreme, privacy law in the United States and many other countries is fragmented, inconsistent, and offers little protection for privacy on the internet and other electronic networks.

For all the passion that surrounds discussions about privacy, and the recent attention devoted to electronic privacy, surprisingly little consensus exists about what privacy means, what values are served--or compromised--by extending further legal protection to privacy, what values are affected by existing and proposed measures designed to protect privacy, and what principles should undergird a sensitive balancing of those values.

In this book, Fred Cate addresses these critical issues in the context of computerized information. He provides an overview of the technologies that are provoking the current privacy debate and discusses the range of legal issues that these technologies raise. He examines the central elements that make up the definition of privacy and the values served, and liabilities incurred, by each of those components. Separate chapters address the regulation of privacy in Europe and the United States. The final chapter identifies four sets of principles for protecting information privacy. The principles recognize the significance of individual and collective nongovernmental action, the limited role for privacy laws and government enforcement of those laws, and the ultimate goal of establishing multinational principles for protecting information privacy.

Privacy in the Information Age involves questions that cut across the fields of business, communications, economics, and law. Cate examines the debate in provocative, jargon-free, detail.
