For the past 20 years, researchers have investigated the use of eye tracking in security
applications. We present a holistic view on gaze-based security applications. In particular …

This second edition of a bestseller presents systematic and extensive coverage of the
primary areas of research and development within VE technology. It brings together a …

Mobile device authentication has been a highly active research topic for over 10 years, with
a vast range of methods proposed and analyzed. In related areas, such as secure channel …

This paper presents an integrated evaluation of the Persuasive Cued Click-Points graphical
password scheme, including usability and security evaluations, and implementation …

Graphical passwords are often considered prone to shoulder-surfing attacks, where
attackers can steal a user's password by peeking over his or her shoulder in the …

We propose a multimodal scheme, GazeTouchPass, that combines gaze and touch for
shoulder-surfing resistant user authentication on mobile devices. GazeTouchPass allows …

The goal of this work is to enable user authentication via finger inputs on ubiquitous surfaces
leveraging low-cost physical vibration. We propose VibWrite that extends finger-input …

Although mobile devices provide access to a plethora of sensitive data, most users still only
protect them with PINs or patterns, which are vulnerable to side-channel attacks (eg …

Given the nature of mobile devices and unlock procedures, unlock authentication is a prime
target for credential leaking via shoulder surfing, a form of an observation attack. While the …

Password-based authentication is easy to use but its security is bounded by how much a
user can remember. Biometrics-based authentication requires no memorization but …
