6. Where are we going?

Abstract

‘Where are we going?’ looks at some other biometric modalities that may achieve a higher profile in future, including hand-based biometrics, keystroke dynamics, ear-shape biometrics, and electrocardiogram and electroencephalogram measurements. It then discusses the problem of ageing in the design and use of biometric systems before considering human interaction with biometric systems and the impact of the usability of systems on their success. Biometrics systems are increasingly and manifestly having an impact on everyday life. Properly understood and sensitively applied, these can improve our security, increase our confidence in processes that are designed to dovetail into the way modern society works, and enhance the convenience and power of technology, for the benefit of everyone.
