MultiGait: A Multi-Sensor Multi-Perspective Multi-Session Biometric Inference Benchmark and its Dataset
Julian Todt, Felix Morsbach, Philip Dissert +1
A lack of suitable datasets has limited the research into the privacy risks of novel smart city sensors, such as thermal cameras, depth cameras, and lidar. Given the number of unsu…
FacialMotionID: Identifying Users of Mixed Reality Headsets using Abstract Facial Motion Representations
Adriano Castro, Simon Hanisch, Matin Fallahi +1
Facial motion capture in mixed reality headsets enables real-time avatar animation, allowing users to convey non-verbal cues during virtual interactions. However, as facial motion…
On the Reliability of Biometric Datasets: How Much Test Data Ensures Reliability?
Matin Fallahi, Ragini Ramesh, Pankaja Priya Ramasamy +3
Biometric authentication is increasingly popular for its convenience and accuracy. However, while recent advancements focus on reducing errors and expanding modalities, the reliabi…
Pantomime: Motion Data Anonymization using Foundation Motion Models
Simon Hanisch, Julian Todt, Thorsten Strufe
Human motion is a behavioral biometric trait that can be used to identify individuals and infer private attributes such as medical conditions. This poses a serious threat to privac…
SEBA: Strong Evaluation of Biometric Anonymizations
Julian Todt, Simon Hanisch, Thorsten Strufe
Biometric data is pervasively captured and analyzed. Using modern machine learning approaches, identity and attribute inferences attacks have proven high accuracy. Anonymizations a…
Beyond Gaze Points: Augmenting Eye Movement with Brainwave Data for Multimodal User Authentication in Extended Reality
Matin Fallahi, Patricia Arias-Cabarcos, Thorsten Strufe
Extended Reality (XR) technologies are becoming integral to daily life. However, password-based authentication in XR disrupts immersion due to poor usability, as entering credentia…
