Taxonomy of behavioural biometrics
This chapter presents a taxonomy of the latest behavioural biometrics, including some future oriented approaches. Current research in the field is examined and analyzed along with the features used to describe different types of behaviour. After comparing accuracy rates for verification of users using different behavioural biometric approaches, researchers address privacy issues which arise or might arise in the future with the use of behavioural biometrics. Finally, generalized properties of behaviour are addressed as well as influence of environmental factors on observed behaviour and potential directions for future research in behavioural biometrics. © 2010, IGI Global.
