RingAuth: Wearable Authentication using a Smart Ring
Jack Sturgess, Simon Birnbach, Simon Eberz +1
In this paper, we show that by using inertial sensor data generated by a smart ring, worn on the finger, the user can be authenticated when making mobile payments or when knocking…
Techniques for Continuous Touch-Based Authentication Modeling
Martin Georgiev, Simon Eberz, Ivan Martinovic
The field of touch-based authentication has been rapidly developing over the last decade, creating a fragmented and difficult-to-navigate area for researchers and application devel…
BeeHIVE: Behavioral Biometric System based on Object Interactions in Smart Environments
Klaudia Krawiecka, Simon Birnbach, Simon Eberz +1
The lack of standard input interfaces in the Internet of Things (IoT) ecosystems presents a challenge in securing such infrastructures. To tackle this challenge, we introduce a nov…
I'm Hearing (Different) Voices: Anonymous Voices to Protect User Privacy
Henry Turner, Giulio Lovisotto, Simon Eberz +1
In this paper, we present AltVoice -- a system designed to help user's protect their privacy when using remotely accessed voice services. The system allows a user to conceal their…
WatchAuth: User Authentication and Intent Recognition in Mobile Payments using a Smartwatch
Jack Sturgess, Simon Eberz, Ivo Sluganovic +1
In this paper, we show that the tap gesture, performed when a user 'taps' a smartwatch onto an NFC-enabled terminal to make a payment, is a biometric capable of implicitly authenti…
FETA: Fair Evaluation of Touch-based Authentication
Martin Georgiev, Simon Eberz, Henry Turner +2
In this paper, we investigate common pitfalls affecting the evaluation of authentication systems based on touch dynamics. We consider different factors that lead to misrepresented…
Daily Turking: Designing Longitudinal Daily-task Studies on Mechanical Turk
Henry Turner, Simon Eberz, Ivan Martinovic
In this paper, we present our system design for conducting longitudinal daily-task studies with the same workers throughout on Amazon Mechanical Turk. We implement this system to c…
Seeing Red: PPG Biometrics Using Smartphone Cameras
Giulio Lovisotto, Henry Turner, Simon Eberz +1
In this paper, we propose a system that enables photoplethysmogram (PPG)-based authentication by using a smartphone camera. PPG signals are obtained by recording a video from the c…
Biometric Backdoors: A Poisoning Attack Against Unsupervised Template Updating
Giulio Lovisotto, Simon Eberz, Ivan Martinovic
In this work, we investigate the concept of biometric backdoors: a template poisoning attack on biometric systems that allows adversaries to stealthily and effortlessly impersonate…
