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 …

Handheld mobile devices store a plethora of sensitive data, such as private emails, personal
messages, photos, and location data. Authentication is essential to protect access to …

Thermal attacks refer to the possibility of capturing heat traces that result from interacting
with user interfaces to reveal sensitive input, such as passwords. The technical feasibility …

With the increasing usage of cameras, the threat from video attacks has greatly increased in
recent years in addition to shoulder surfing. Many organizations have implemented two …

Smartphones provide access to increasing amounts of personal and sensitive information,
yet are often only secured using methods that are prone to observational attacks. We …

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 …

We investigate the effectiveness of thermal attacks against input of text with different
characteristics; we study text entry on a smartphone touchscreen and a laptop keyboard …

Thermal cameras can be used to detect user input on interfaces, such as touchscreens,
keyboards, and PIN pads, by recording the heat traces left by the users' fingers after …

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 …
