In search of the silver bullet to solve the password problem, the field of knowledge-based
authentication has become bloated with novel proposals aiming to replace textual …

PINs and patterns remain among the most widely used knowledge-based authentication
schemes. As thermal cameras become ubiquitous and affordable, we foresee a new form of …

The adoption of Augmented Reality (AR) technology has increased over the years. AR
enhances various activities for consumers and businesses, particularly in industrial contexts …

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 …

Evaluating novel authentication systems is often costly and time-consuming. In this work, we
assess the suitability of using Virtual Reality (VR) to evaluate the usability and security of …

Eye-gaze and mid-air gestures are promising for resisting various types of side-channel
attacks during authentication. However, to date, a comparison of the different authentication …

Secure authentication on situated displays (eg, to access sensitive information or to make
purchases) is becoming increasingly important. A promising approach to resist shoulder …

We evaluate the efficacy of shoulder surfing defenses for PIN-based authentication systems.
We find tilting the device away from the observer, a widely adopted defense strategy …

Given the difficulties of studying the shoulder surfing resistance of authentication systems in
a live setting, researchers often ask study participants to shoulder surf authentications by …

Augmented Reality (AR) Head-Mounted Displays (HMD) are increasingly used in industry to
digitize processes and enhance user experience by enabling real-time interaction with both …
