Longitudinal Study of Facial Biometrics at the BEZ: Temporal Variance Analysis
Mathias Schulz, Alexander Spenke, Pia Funk +6
This study presents findings from long-term biometric evaluations conducted at the Biometric Evaluation Center (bez). Over the course of two and a half years, our ongoing research…
Towards Fingerprint Mosaicking Artifact Detection: A Self-Supervised Deep Learning Approach
Laurenz Ruzicka, Alexander Spenke, Stephan Bergmann +3
Fingerprint mosaicking, which is the process of combining multiple fingerprint images into a single master fingerprint, is an essential process in modern biometric systems. However…
An arbiter PUF secured by remote random reconfigurations of an FPGA
Alexander Spenke, Ralph Breithaupt, Rainer Plaga
We present a practical and highly secure method for the authentication of chips based on a new concept for implementing strong Physical Unclonable Function (PUF) on field programma…
