This groundbreaking text examines the problem of user authentication from a completely new viewpoint. Rather than describing the requirements, technologies and implementation issues of designing point-of-entry authentication, the book introduces and investigates the technological requirements of implementing transparent user authentication - where authentication credentials are captured during a user´s normal interaction with a system. This approach would transform user authentication from a binary point-of-entry decision to a continuous identity confidence measure. Topics and features: discusses the need for user authentication; reviews existing authentication approaches; introduces novel behavioural biometrics techniques; examines the wider system-specific issues with designing large-scale multimodal authentication systems; concludes with a look to the future of user authentication.

From the reviews:

"This book is worth reading. ... Clarke provides an architectural description with many tradeoffs that may help in building such a system. This book, with its clear focus on transparent authentication, brings together a lot of ideas and insights." (A. Mari‰n, ACM Computing Reviews, March, 2012)
