User Study: Comparison of Picture Passwords and Current Login Approaches
In this research, we conduct a user study that compares different
computer/system authentication methods. More specifically, we look into
comparing regular password authentication with picture authentication. Picture
authentication means selecting a sequence of pictures from a set of pictures
(30). We present users with both interfaces; various metrics are tracked while
the participants conduct a variety of user authentication-related tasks. Other
metrics include user perception of security with such technologies
Using Gaze for Behavioural Biometrics
A principled approach to the analysis of eye movements for behavioural biometrics is laid
down. The approach grounds in foraging theory, which provides a sound basis to capture the unique-
ness of individual eye movement behaviour. We propose a composite Ornstein-Uhlenbeck process for
quantifying the exploration/exploitation signature characterising the foraging eye behaviour. The rel-
evant parameters of the composite model, inferred from eye-tracking data via Bayesian analysis, are
shown to yield a suitable feature set for biometric identification; the latter is eventually accomplished
via a classical classification technique. A proof of concept of the method is provided by measuring
its identification performance on a publicly available dataset. Data and code for reproducing the
analyses are made available. Overall, we argue that the approach offers a fresh view on either the
analyses of eye-tracking data and prospective applications in this field
