This book constitutes the refereed conference proceedings of the 9th Annual Privacy Forum, APF 2021. Due to COVID-19 pandemic the conference was held virtually. The 9 revised full papers were carefully reviewed and selected from 43 submissions. The papers are organized in topical sections on Implementing Personal Data Processing Principles; Privacy Enhancing Technologies; Promoting Compliance with the GDPR.

This textbook provides a unique lens through which the myriad of existing Privacy Enhancing Technologies (PETs) can be easily comprehended and appreciated. It answers key privacy-centered questions with clear and detailed explanations. Why is privacy important? How and why is your privacy being eroded and what risks can this pose for you? What are some tools for protecting your privacy in online environments? How can these tools be understood, compared, and evaluated? What steps can you take to gain more control over your personal data? This book addresses the above questions by focusing on three fundamental elements: It introduces a simple classification of PETs that allows their similarities and differences to be highlighted and analyzed; It describes several specific PETs in each class, including both foundational technologies and important recent additions to the field; It explains how to use this classification to determine which privacy goals are actually achievable in a given real-world environment. Once the goals are known, this allows the most appropriate PETs to be selected in order to add the desired privacy protection to the target environment. To illustrate, the book examines the use of PETs in conjunction with various security technologies, with the legal infrastructure, and with communication and computing technologies such as Software Defined Networking (SDN) and Machine Learning (ML). Designed as an introductory textbook on PETs, this book is essential reading for graduate-level students in computer science and related fields, prospective PETs researchers, privacy advocates, and anyone interested in technologies to protect privacy in online environments.

Privacy and Technologies of Identity: A Cross-Disciplinary Conversation provides an overview of ways in which technological changes raise privacy concerns. It then addresses four major areas of technology: RFID and location tracking technology; biometric technology, data mining; and issues with anonymity and authentication of identity. Many of the chapters are written with the non-specialist in mind, seeking to educate a diverse audience on the "basics" of the technology and the law and to point out the promise and perils of each technology for privacy. The material in this book provides an interface between legal and policy approaches to privacy and technologies that either threaten or enhance privacy. This book grew out of the Fall 2004 CIPLIT(r) Symposium on Privacy and Identity: The Promise and Perils of a Technological Age, co-sponsored by DePaul University's College of Law and School of Computer Science, Telecommunications and Information Systems. The Symposium brought together leading researchers in advanced technology and leading thinkers from the law and policy arenas, many of whom have contributed chapters to the book. Like the Symposium, the book seeks to contribute to a conversation among technologists, lawyers, and policymakers about how best to handle the challenges to privacy that arise from recent technological advances.

Privacy is one of the most urgent issues associated with information technology and digital media. This book claims that what people really care about when they complain and protest that privacy has been violated is not the act of sharing information itself—most people understand that this is crucial to social life —but the inappropriate, improper sharing of information. Arguing that privacy concerns should not be limited solely to concern about control over personal information, Helen Nissenbaum counters that information ought to be distributed and protected according to norms governing distinct social contexts—whether it be workplace, health care, schools, or among family and friends. She warns that basic distinctions between public and private, informing many current privacy policies, in fact obscure more than they clarify. In truth, contemporary information systems should alarm us only when they function without regard for social norms and values, and thereby weaken the fabric of social life.

Privacy-invading technologies (PITs) such as Body scanners; Public space CCTV microphones; Public space CCTV loudspeakers and Human-implantable microchips (RFID implants/GPS implants) are dealt with in this book. The book shows how and why laws that regulate the design and development of privacy-invading technologies (PITs) may more effectively ensure the protection of privacy than laws that only regulate data controllers and the use of such technologies. The premise is supported and demonstrated through a discussion on these four specific PITs as case studies. In doing so, the book overall attempts to explain how laws/regulations that mandate the implementation of Privacy by Design (PBD) could potentially serve as a viable approach for collectively safeguarding privacy, liberty and security in the 21st Century. This book will be of interest to academic researchers, law practitioners, policy makers and technology researchers.

This book constitutes the refereed conference proceedings of the 7th Annual Privacy Forum, APF 2019, held in Rome, Italy, in June 2019. The 11 revised full papers were carefully reviewed and selected from 49 submissions. The papers present original work on the themes of data protection and privacy and their repercussions on technology, business, government, law, society, policy and law enforcement bridging the gap between research, business models, and policy. They are organized in topical sections on transparency, users' rights, risk assessment, and applications.
