“The Domains of Identity” defines sixteen simple and comprehensive categories of transactions which cause personally identifiable information to be stored in databases. This research, which builds on the synthesis of over 900 academic articles, addresses the challenges of identity management that involve interactions of almost all people in almost all institutional/organizational contexts. Enumerating the sixteen domains and describing the characteristics of each domain clarifies which problems can arise and how they can be solved within each domain.



Discussions of identity management are often confusing because they mix issues from multiple domains, or because they try unsuccessfully to apply solutions from one domain to problems in another. This book is an attempt to eliminate the confusion and enable clearer conversations about identity management problems and solutions.



Who owns our digital identity? Is ownership even a relevant concept here? Who controls our digital identity (or pieces of it)? What is the correct relationship between the individual, the state, and private actors and organizations, with respect to one’s identity? What do emerging technical architectures do to potentially create alignment? What identity is required to get identity documents? Kaliya Young guides us through these and other questions we need to be asking to solve our society’s complex identity challenges.
