An Attack on Facial Soft-biometric Privacy Enhancement
Dailé Osorio-Roig, Christian Rathgeb, Pawel Drozdowski +3
In the recent past, different researchers have proposed privacy-enhancing face recognition systems designed to conceal soft-biometric attributes at feature level. These works have…
Differential Anomaly Detection for Facial Images
Mathias Ibsen, Lázaro J. González-Soler, Christian Rathgeb +3
Due to their convenience and high accuracy, face recognition systems are widely employed in governmental and personal security applications to automatically recognise individuals.…
SynCoLFinGer: Synthetic Contactless Fingerprint Generator
Jannis Priesnitz, Christian Rathgeb, Nicolas Buchmann +1
We present the first method for synthetic generation of contactless fingerprint images, referred to as SynCoLFinGer. To this end, the constituent components of contactless fingerpr…
Feature Fusion Methods for Indexing and Retrieval of Biometric Data: Application to Face Recognition with Privacy Protection
Pawel Drozdowski, Fabian Stockhardt, Christian Rathgeb +2
Computationally efficient, accurate, and privacy-preserving data storage and retrieval are among the key challenges faced by practical deployments of biometric identification syste…
Demographic Fairness in Face Identification: The Watchlist Imbalance Effect
Pawel Drozdowski, Christian Rathgeb, Christoph Busch
Recently, different researchers have found that the gallery composition of a face database can induce performance differentials to facial identification systems in which a probe im…
Demographic Fairness in Biometric Systems: What do the Experts say?
Christian Rathgeb, Pawel Drozdowski, Naser Damer +2
Algorithmic decision systems have frequently been labelled as "biased", "racist", "sexist", or "unfair" by numerous media outlets, organisations, and researchers. There is an ongoi…
Impact of Facial Tattoos and Paintings on Face Recognition Systems
Mathias Ibsen, Christian Rathgeb, Thomas Fink +2
In the past years, face recognition technologies have shown impressive recognition performance, mainly due to recent developments in deep convolutional neural networks. Notwithstan…
Signal-level Fusion for Indexing and Retrieval of Facial Biometric Data
Pawel Drozdowski, Fabian Stockhardt, Christian Rathgeb +1
The growing scope, scale, and number of biometric deployments around the world emphasise the need for research into technologies facilitating efficient and reliable biometric ident…
Effects of Image Compression on Face Image Manipulation Detection: A Case Study on Facial Retouching
Christian Rathgeb, Kevin Bernardo, Nathania E. Haryanto +1
In the past years, numerous methods have been introduced to reliably detect digital face image manipulations. Lately, the generalizability of these schemes has been questioned in p…
Mobile Touchless Fingerprint Recognition: Implementation, Performance and Usability Aspects
Jannis Priesnitz, Rolf Huesmann, Christian Rathgeb +2
This work presents an automated touchless fingerprint recognition system for smartphones. We provide a comprehensive description of the entire recognition pipeline and discuss impo…
