Digital identity management is a broad term; but when applied to information security, refers to identifying users with a network, application or system and controlling their access to resources within those systems and applications.
An interesting point made early in Digital Identity Management (Elsevier 978-1785480041) is that French Interest users averaged 16.4 digital ID’s in 2013; which is up from 12.2 in 2009. It’s likely that by now, that number is over 20, and is representative of users worldwide.
The reason French users are highlighted is that authors Maryline Laurent and Samia Bouzefrane are both professors in computer science at French universities. The other contributors to the book are also based in the EU and the book therefore has a slant to European-based identic management.
The 5 chapters in the book takes a broad look at identity management from perspectives such as social networks, cloud, IoT and more. The book is written by academics and has an academic feel to it. Those looking for a reference on how to implement an identity management solution will have to look elsewhere.
The book is a good resource for an academic introduction to the topic, and lends itself to a college level class. Digital Identity Management provides a deep introduction to the abstract areas and core topics of identity management.
