I Feel Like I'm Taking Selfies All Day!

Abstract

We present the results of an MTurk survey (n = 383) on the reasons for using and not using biometric authentication systems on smartphones. We focused on Apple's Touch ID as well as Android's Face Unlock as they are the most prevalent systems on the market. For both systems, we categorized the participants as a) current users, b) former users that deactivated it at some point and c) nonusers. The results show that usability is one of the main factors that influences the decision on whether or not to use biometric verification on the smartphone. To our surprise and as opposed to previous research on biometric authentication, privacy and trust issues were not among the most important decision factors.

Stay Cool! Understanding Thermal Attacks on Mobile-based User Authentication

“…One group of authentication schemes resilient against thermal attacks rely on one or more modalities other than touch input. For example, biometrics schemes (for example, [10,13,25,26]) rely on data collected by sensors, such as accelerometers, to identify the user. Since they do not use the touch screen for dedicated input, they are not vulnerable to thermal attacks.…”

A survey on touch dynamics authentication in mobile devices

“…According to the survey results reported by (De Luca et al, 2015), one of the important factors influencing the participants' choice as which biometrics authentication method they prefer to use on a mobile device is the usability factor. They identified two primary usability issues that put off participants' adaptation of a biometrics authentication method, namely, (i) slow authentication speed and inconvenience and (ii) social awkwardness.…”

Free-Form Gesture Authentication in the Wild

“…Text passwords, although still the most used authentication method, have been criticized by many [5,6,1], and found to be particularly unsuitable for mobile use [43,64,60]. Other existing methods (PIN, grid-based pattern, biometrics) on mobile devices suffer from various shortcomings: limited password space [58], susceptibility to shoulder surfing [18,61], easily crackable [7,8,55], slow entry [17] and harmful for privacy [15].…”
