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 …

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

Secure and usable user authentication on mobile headsets is a challenging problem. The
miniature-sized touchpad on such devices becomes a hurdle to user interactions that impact …

As public displays continue to deliver increasingly private and personalized content, there is
a need to ensure that only the legitimate users can access private information in sensitive …

In this paper, we present XSide, an authentication mechanism that uses the front and the
back of smartphones to enter stroke-based passwords. Users can switch sides during input …

Research has brought forth a variety of authentication systems to mitigate observation
attacks. However, there is little work about shoulder surfing situations in the real world. We …

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 …

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 present PathWord (PATH passWORD), a multimodal digit entry method for ad-hoc
authentication based on known digits shape and user relative eye movements. PathWord is …
