This paper proposes an Out-of-Device Privacy Scale (ODPS)-a reliable, validated
psychometric privacy scale that measures users' importance of out-of-device privacy. In …

Thermal cameras can reveal heat traces on user interfaces, such as keyboards. This can be
exploited maliciously to infer sensitive input, such as passwords. While previous work …

Thermal attacks are an emerging threat that enables the reconstruction of user input after
interaction with a device by analysing heat traces. There are several ways to protect users …

We propose a paradigm shift in human-centered security research in which users' objective
behavior and physiological states move into focus. This proposal is motivated by the fact that …

Randomizing the layout of the keypad has been proposed to improve the security of PIN
entry. However, there has been no empirical quantification of its impact on usability and …

Thermal attacks targeting large-scale integrated microsystems, such as three-dimensional
package systems (3D-SiP), exploit thermal fluctuations to compromise their security. These …

Shoulder surfing has been studied extensively, however, it remains unexplored whether and
how it impacts users. Understanding this is important as it determines whether shoulder …

Shoulder-surfing studies in the context of mobile user authentication have focused on
evaluating the attackers' performance, yet have paid much less attention to their perception …

Thermal cameras have become portable enough to integrate into wearables, such as
glasses, and can be used maliciously to infer passwords observing heat traces left on …

These days, the scope of a huge number of web, desktop, IoT, cloud and mobile
applications being compromised is rapidly increasing. The attackers exploit weak …
