  Another discussion of privacy as a concept and its role and associated tensions in discussions of advancing technology, is Privacy: What Everyone Needs to Know, (Francis &amp; Francis, 2017). It provides an excellent new overview of the literature and topics covered in this article. It is both a thoughtful and expansive book, discussing privacy as it relates to concepts such as security and autonomy in decision-making. Also assessing the state of privacy in our changing technological era, the book addresses privacy questions for individuals, families and other groups, with detailed attention to personal information, health care, education, employment and other financial issues, law enforcement, the Internet and social media, and the importance of privacy in a democracy. It gives a balanced treatment of alternative views in each of these areas, emphasizing the multiple ways protection of privacy can vary substantially in different spheres of our lives. The authors have expertise in both philosophy and law, which is particularly timely and increasingly necessary in any discussion of the value of privacy in these multiple contexts.
