The social benefit derived from Online Social Networks (OSNs) can lure users to reveal unprecedented volumes of personal data to an online audience that is much less trustworthy than their offline social circle. Even if a user hides his personal data from some users and shares with others, privacy settings of OSNs may be bypassed, thus leading to various privacy harms such as identity theft, stalking, or discrimination. Therefore, users need to be assisted in understanding the privacy risks of their OSN profiles as well as managing their privacy settings so as to keep such risks in check, while still deriving the benefits of social network participation. This book presents to its readers how privacy risk analysis concepts such as privacy harms and risk sources can be used to develop mechanisms for privacy scoring of user profiles and for supporting users in privacy settings management in the context of OSNs. Privacy scoring helps detect and minimize the risks due to the dissemination and use of personal data. The book also discusses many open problems in this area to encourage further research.

Measuring privacy risk in online social networks is a challenging task. One of the fundamental difficulties is quantifying the amount of information revealed unintentionally. We present PrivAware, a tool to detect and report unintended information loss in online social networks. Our goal is to provide a rudimentary framework to identify privacy risk and provide solutions to reduce information loss. The first instance of the software is focused on information loss attributed to social circles. In subsequent releases we intend to incorporate additional capabilities to capture ancillary threat models. From our initial results, we quantify the privacy risk attributed to friend relationships in Facebook. We show that for each user in our study a majority of their personal attributes can be derived from social contacts. Moreover, we present results denoting the number of friends contributing to a correctly inferred attribute. We also provide similar results for different demographics of users. The intent of PrivAware is to not only report information loss but to recommend user actions to mitigate privacy risk. The actions provide users with the steps necessary to improve their overall privacy measurement. One obvious, but not ideal, solution is to remove risky friends. Another approach is to group risky friends and apply access controls to the group to limit visibility. In summary, our goal is to provide a unique tool to quantify information loss and provide features to reduce privacy risk.

This volume constitutes the refereed proceedings of the Third International Conference on HCI in Business, Government and Organizations, HCIBGO 2016, held as part of the 18th International Conference on Human-Computer Interaction, HCII 2016, which took place in Toronto, Canada, in July 2016. HCII 2016 received a total of 4354 submissions, of which 1287 papers were accepted for publication after a careful reviewing process. The 53 papers presented in this volume are organized in topical sections named: social media for business; electronic, mobile and ubiquitous commerce; business analytics and visualization; branding, marketing and consumer behavior; and digital innovation.

The value of personal data has traditionally been understood in ethical terms as a safeguard for personality rights such as human dignity and privacy. However, we have entered an era where personal data are mined, traded and monetized in the process of creating added value - often in terms of free services including efficient search, support for social networking and personalized communications. This volume investigates whether the economic value of personal data can be realized without compromising privacy, fairness and contextual integrity. It brings scholars and scientists from the disciplines of computer science, law and social science together with policymakers, engineers and entrepreneurs with practical experience of implementing personal data management. The resulting collection will be of interest to anyone concerned about privacy in our digital age, especially those working in the field of personal information management, whether academics, policymakers, or those working in the private sector.

Technology provides accessibility otherwise unavailable to the people who can benefit from it the most. As new digital tools become less expensive and more widely available, research and real-world cases that examine the union between emergent countries and information systems are essential in determining the next steps for these nations. The Handbook of Research on Managing Information Systems in Developing Economies is a pivotal reference source that explores the effects of technological data handling within developing economies. Covering a broad range of topics such as emerging digital technologies, socio-economic development, and technology startups, this book is ideally designed for software programmers, policymakers, practitioners, educators, academicians, students, and researchers.

This book is the second of three volumes that illustrate the concept of social networks from a computational point of view. The book contains contributions from a international selection of world-class experts, concentrating on topics relating to security and privacy (the other two volumes review Tools, Perspectives, and Applications, and Mining and Visualization in CSNs). Topics and features: presents the latest advances in security and privacy issues in CSNs, and illustrates how both organizations and individuals can be protected from real-world threats; discusses the design and use of a wide range of computational tools and software for social network analysis; describes simulations of social networks, and the representation and analysis of social networks, with a focus on issues of security, privacy, and anonymization; provides experience reports, survey articles, and intelligence techniques and theories relating to specific problems in network technology.

This timely guide examines the influence of social media in private, public, and professional settings, particularly the ethical implications of the cultural changes and trends created by their use. In the quest for quick dissemination of information, web users and content providers find both opportunity and liability in digital broadcasts. Examples abound: Twitter members tap into news reports well in advance of traditional print media, but stories are prone to inaccuracies and misinformation; Facebook shares useful data mined from member profiles, but this sharing often compromises privacy. It is no surprise that use of social media gives rise to a host of moral dilemmas never before encountered. This book sheds light on the effects of this new medium on the individual and society. Through two volumes chock full of topics found in news headlines everyday, the authors look at evolving trends in social media and their impact on privacy, politics, and journalism. The first volume explores the role of this technology on national and international security. Volume 2 focuses on the individual as both a producer and consumer of internet content, showing how the media itself is changing notions of self-identity, relationships, and popular culture. The book's content covers such topics as individual and community psychology, citizen journalism, and corporate technology.

This book constitutes the thoroughly refereed post conference proceedings of the 5th IFIP WG 9.2, 9.6/11.7, 11.4, 11.6/PrimeLife International Summer School, held in Nice, France, in September 2009. The 25 revised papers were carefully selected from numerous submissions during two rounds of reviewing. They are organized in topical sections on lifelong privacy, privacy for social network sites and collaborative systems, privacy for e-government applications, privacy and identity management for e-health and ambient assisted living applications, anonymisation and privacy-enhancing technologies, identity management and multilateral security, and usability, awareness and transparency tools.
