Research on keystroke dynamics biometrics has been increasing, especially in the last
decade. The main motivation behind this effort is due to the fact that keystroke dynamics …

We introduce hand movement, orientation, and grasp (HMOG), a set of behavioral features
to continuously authenticate smartphone users. HMOG features unobtrusively capture subtle …

We investigate whether a classifier can continuously authenticate users based on the way
they interact with the touchscreen of a smart phone. We propose a set of 30 behavioral touch …

Mobile devices and technologies have become increasingly popular, offering comparable
storage and computational capabilities to desktop computers allowing users to store and …

Designing reliable user authentication on mobile phones is becoming an increasingly
important task to protect users' private information and data. Since biometric approaches can …

Mobile cloud computing (MCC) is the state-of-the-art mobile distributed computing model
that incorporates multitude of heterogeneous cloud-based resources to augment …

It is perhaps unsurprising to find much of the focus in IT and computer security being drawn
towards the technical aspects of the discipline. However, it is increasingly recognised that …

BACKGROUND Prior to the advent and prolific use of distributed network environments such
as the Internet, customer service sessions typically occurred over a teleconference between …

Mobile phones are rapidly becoming small-size general purpose computers, so-called
smartphones. However, applications and data stored on mobile phones are less protected …
