Behavioural Biometric Authentication For Mobile Devices |
It is commonly acknowledged that mobile devices now form an integral part of an individual’s

everyday life. As the amount of valuable and sensitive information stored on a mobile device
increases, so does the need for effective security. In order to protect unauthorised access, an
authentication system is required. Biometric authentication has proven to be a more reliable
solution than knowledge based and token based techniques. Indeed, biometric techniques are
uniquely individual, impossible to forget or lose, difficult to reproduce or falsify and difficult
to change or hide. Despite the well known advantages of biometric authentication approaches,
the majority of current state-of-the-art mobile devices embrace point of entry authentication
systems including PIN/passwords and one time fingerprint verification. This paper begins by
discussing the limitations of current state-of-the-art authentication approaches together with
preliminary findings of an experiment using finger pressure authentication. The potential of
linguistic profiling is explored and results of a secondary experiment highlighted the potential
for a continuous, transparent and non-intrusive behaviour biometric authentication system for
mobile devices.
