An Attack on Facial Soft-Biometric Privacy Enhancement
Osorio-Roig, Daile; Rathgeb, Christian; Drozdowski, Pawel; Terhorst, Philipp; Struc, Vitomir; Busch, Christoph (Peer reviewed; Journal article, 2022)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 reported impressive results, but generally ... -
Benchmarking Binarisation Schemes for Deep Face Templates
Drozdowski, Pawel; Struck, Florian; Rathgeb, Christian; Busch, Christoph (Chapter, 2018)Feature vectors extracted from biometric characteristics are often represented using floating point values. It is, however, more appealing to store and compare feature vectors in a binary representation, since it generally ... -
Computational Workload in Biometric Identification Systems: An Overview
Drozdowski, Pawel; Rathgeb, Christian; Busch, Christoph (Journal article; Peer reviewed, 2019)Computational workload is one of the key challenges in biometric identification systems. The na{\"i}ve retrieval method based on an exhaustive search becomes impractical with the growth of the number of the enrolled data ... -
Database Binning and Retrieval in Multi-Fingerprint Identification Systems
Drozdowski, Pawel; Fischer, Daniel; Rathgeb, Christian; Schiel, Christopher; Busch, Christoph (Chapter, 2018)The increasingly large scale of deployed biometric systems necessitates approaches for computational workload reduction in order to perform identification queries efficiently. Simple database binning based on classification ... -
Detection of Glasses in Near-Infrared Ocular Images
Drozdowski, Pawel; Struck, Florian; Rathgeb, Christian; Busch, Christoph (Chapter, 2018)Eyeglasses change the appearance and visual perception of facial images. Moreover, under objective metrics, glasses generally deteriorate the sample quality of near-infrared ocular images and as a consequence can worsen ... -
Efficient privacy-preserving biometric identification in largescale multibiometric systems
Drozdowski, Pawel (Doctoral theses at NTNU;2020:115, Doctoral thesis, 2020)In recent years, applications of biometric systems on national and international scale have appeared. Biometric identification is one of the important operational modes of such systems. It entails ascertaining the data ... -
Facilitating free travel in the Schengen area—A position paper by the European Association for Biometrics
Busch, Christoph; Deravi, Farzin; Frings, Dinusha; Kindt, Els; Lessmann, Ralph; Nouak, Alexander; Salomon, Jean; Achcar, Mateus; Alonso-Fernandez, Fernando; Bachenheimer, Daniel; Bethell, David; Bigun, Josef; Brawley, Matthew; Brockmann, Guido; Cabello, Enrique; Campisi, Patrizio; Cepilovs, Aleksandrs; Clee, Miles; Cohen, Mickey; Croll, Christian; Czyżewski, Andrzej; Dorizzi, Bernadette; Drahansky, Martin; Drozdowski, Pawel; Fankhauser, Catherine; Fierrez, Julian; Gomez-Barrero, Marta; Hasse, Georg; Guest, Richard; Komleva, Ekaterina; Marcel, Sebastien; Marcialis, Gian Luca; Mercier, Laurent; Mordini, Emilio; Mouille, Stefance; Navratilova, Pavlina; Ortega-Garcia, Javier; Petrovska, Dijana; Poh, Norman; Racz, Istvan; Ramachandra, Raghavendra; Rathgeb, Christian; Remillet, Christophe; Seidel, Uwe; Spreeuwers, Luuk; Strand, Brage; Toivonen, Sirra; Uhl, Andreas (Peer reviewed; Journal article, 2023)Due to migration, terror-threats and the viral pandemic, various EU member states have re-established internal border control or even closed their borders. European Association for Biometrics (EAB), a non-profit organisation, ... -
Iris Recognition in Visible Wavelength: Impact and automated Detection of Glasses
Osorio-Roig, Daile; Drozdowski, Pawel; Rathgeb, Christian; Morales-González, Annette; Garea-Llano, Eduardo; Busch, Christoph (Chapter, 2018)The prevalence of visual impairment around the world is rapidly increasing, causing large numbers of people to wear glasses. Glasses are generally considered an important noise source in iris recognition; under objective ... -
Multi-biometric Identification with Cascading Database Filtering
Drozdowski, Pawel; Mokroß, Benedikt-Alexander; Rathgeb, Christian; Busch, Christoph (Journal article, 2020)The growing scale and number of biometric deployments around the world necessitates research into technologies which facilitate fast identification queries and high discriminative power. In this context, this article ... -
On the Application of Homomorphic Encryption to Face Identification
Drozdowski, Pawel; Buchmann, Nicolas; Rathgeb, Christian; Margraf, Marian; Busch, Christoph (Chapter, 2019)The data security and privacy of enrolled subjects is a critical requirement expected from biometric systems. This paper addresses said topic in facial biometric identification. In order to fulfil the properties of ... -
Privacy-Preserving Indexing of Iris-Codes with Cancelable Bloom Filter-based Search Structures
Drozdowski, Pawel; Garg, Surabhi; Rathgeb, Christian; Gomez-Barrero, Marta; Chang, Donghoon; Busch, Christoph (Chapter, 2018)Protecting the privacy of the enrolled subjects is an important requirement expected from biometric systems. In recent years, numerous template protection schemes have been proposed, but so far none of them have been shown ... -
