Automatic speaker verification (ASV) is among the most convenient, natural and efficient approaches to biometric authentication. Despite the appeal, and like the majority of all biometric systems, ASV is vulnerable to being manipulated by adversaries through spoofing or presentation attacks (PAs). Substantial interest in anti-spoofing or presentation attack detection (PAD) for ASV began only in 2013, with the first competitive challenge known as ASVspoof being held in 2015. Having attracted the participation of 62 independent teams for the 2019 edition, ASVspoof is now one of the largest community-supported anti-spoofing benchmarking challenges. This talk will describe the vulnerabilities of ASV systems to spoofing and PAs, the strategy behind ASVspoof as well as the progress made in the last five years. This shows that the best performing spoofing countermeasures or PAD systems can detect reliably even deepfake synthetic speech or converted voice attacks that humans are incapable of distinguishing from bona fide speech.

This talk will discuss the results of the EU funded project “Towards the European Level Exchange of Facial Images“ (TELEFI project). This project studied how facial recognition is used to investigate crime across EU Member States. In addition, particular consideration was given to the potential for implementing the exchange of facial images within the Prüm framework.

Currently, DNA profiles, fingerprints and vehicle registration data are exchanged within the Prüm framework for combating cross-border crime, terrorism and illegal migration. The Prüm system has been successfully employed for many years and it had reached a point where the introduction of new modalities, including facial images, were considered.

The TELEFI project was conducted by a group of six European institutions: Estonian Forensic Science Institute, Estonian Police and Border Guard Board, Finnish National Bureau of Investigation, Latvian State Forensic Science Bureau, Netherlands Forensic Institute and Swedish National Forensic Centre.

This talk will discuss the administrative and law enforcement use of facial recognition in criminal investigation, will provide a summary of the project, and present the recommendations for the EU Member States.

As identity is a fundamental right to protect, reliable Biometrics can be key to ensuring this right as long as they are integrated in systems that protect the user’s privacy. IN Groupe develops identity solutions and secure digital services that guarantee this all in providing seamless user experience. This presentation will describe some use cases of these systems and focus on their face biometric functionalities.

The speakers will review key principles that ensure that a face recognition solution is RGPD compliant. They will also describe IN Groupe’s face presentation attack detection solutions. These are essential because presentation attacks can compromise the reliability of biometric data at capture point and therefore threaten the security of the entire system. Solutions achieved have high accuracy and bear the advantage of being passive, meaning that they do not require any specific action from the user.

From the early days, when security was the driving force behind biometric research, today’s challenges go far beyond security. Machine learning, Image understanding, Signal analysis, Neuroscience, Robotics, Forensic science, Digital forensics and other disciplines, converged in a truly multidisciplinary effort to devise and build advanced systems to facilitate the interpretation of signals recorded from individuals acting in a given environment. This is what we simply call today “Biometrics”.

For the last eighteen years, the International Summer School on Biometrics has been closely following the developments in science and technology to offer a cutting edge, intensive training course, always up to date with the current state-of-the-art.

What are the most up-to-date core biometric technologies developed in the field? What is the potential impact of biometrics in forensic investigation and crime prevention? What can we learn from human perception? How to deploy current Deep Learning approaches? How to deal with adversarial attacks in biometric recognition?

This school follows the successful track of the International Summer Schools on Biometrics held since 2003. In this 18th edition, the courses will mainly focus on new and emerging issues:

• The impact of AI in Biometrics and Biometrics in AI;
• How to make “Deep Biometrics” systems explainable;
• Biometrics for social interactions and emerging applications;
• How to exploit new biometric technologies in forensic and security applications.

The courses will provide a clear and in-depth picture on the state-of-the-art in biometric verification/identification technology, both under the theoretical and scientific point of view as well as in diverse application domains. The lectures will be given by, at least, 18 outstanding experts in the field, from both academia and industry.

An advanced feature of this summer school will be some practical sessions to better understand, “hands on”, the real potential of today’s biometric technologies.

The Norwegian Biometrics Forum (NBF) is an open platform dedicated to regular exchange of information and experience related to the field of Biometrics.

In the regular meetings new applications, latest research results and products are presented.

Touchless fingerprint recognition represents a rapidly growing field of research which has been studied for more than a decade. Through a touchless acquisition process many issues of touch-based systems are circumvented, e.g. the presence of latent fingerprints or distortions caused by pressing fingers on a sensor surface. However, touchless fingerprint recognition systems reveal new challenges. In particular, a reliable detection and focusing of a presented finger as well as an appropriate preprocessing of the acquired finger image represent the most crucial tasks. Also, further issues, e.g. interoperability between touchless and touch-based fingerprints or presentation attack detection, are currently investigated by different research groups. Many works have been proposed so far to put touchless fingerprint recognition into practise. Published approaches range from self identification scenarios with commodity devices, e.g. smartphones, to high performance on-the-move deployments paving the way for new fingerprint recognition application scenarios. This talk summarizes the state-of-the-art in the field of touchless 2D fingerprint recognition at each stage of the recognition process. Additionally, technical considerations and trade-offs of the presented methods are discussed along with open issues and challenges.

PriMa (Privacy Matters) is an Innovative Training Network (ITN) funded by the EU through the Horizon 2020 Framework. PriMa is a collaboration between 7 research locations and 7 industrial partner organisations with a focus on the analysis and mitigation of privacy risks in a rapidly digitalising society. One factor contributing to the erosion of privacy is the growth in recognition technologies that not only facilitate the recognition of individuals but also the inference from biometric data of emotional state, gender, health, age, and even profession. Another factor is the fast advancement of artificial intelligence, allowing for extensive data mining, and aggregation, linkage and inference of personal information. Hence, there is a real possibility that acceptable privacy may become unattainable unless technological and societal steps are taken to allow citizens to regain control of their personal information. Therefore, the overall objectives of PriMa are:

• To train 14 creative, entrepreneurial, and innovative researchers as privacy protection experts.
• To contribute to a full understanding of the multidisciplinary nature of privacy protection in a digitalised society.
• To contribute to the development of solutions that address this important societal challenge.

PriMa will train a next generation of researchers to define, investigate and implement solutions that ensure secure and efficient privacy protection whilst keeping the advantages of a digitalised society, and provide them with transferable skills to enable effective planning, management and communication of research ideas and outcomes. This will give them excellent career opportunities.

Many articles have used voice analysis to detect Parkinson’s disease (PD), but few have focused on the early stages of the disease, the impact of telephonic recordings, and the gender effect. We have adapted the latest speaker recognition system, called x-vectors, in order to detect PD at an early stage using voice analysis. X-vectors are embeddings extracted from Deep Neural Networks (DNNs), which provide robust speaker representations and improve speaker recognition when large amounts of training data are used.

We recorded 221 French speakers (recently diagnosed PD subjects and healthy controls) with a high-quality microphone and via the telephone network. We assessed the impact of the audio segment durations, data augmentation, type of dataset used for the neural network training, kind of speech tasks, and back-end analyses. X-vectors technique provided better classification performances than classical Gaussian Mixture Models for the text-independent tasks, and seemed to be particularly suited for the early detection of PD in women (7 to 15% improvement).

Dijana Petrovska-Delacrétaz obtained her degree in Physics and her PhD from the Swiss Federal Institute of Technology (EPFL) in Lausanne. She was working as a consultant at AT&T, as a post-Doc at Télécom ParisTech, and as a Senior Scientist in the Informatics Department of Fribourg University, Switzerland. Since 2004 she joined Télécom SudParis as Associate Professor. Her research activities are oriented towards pattern recognition, signal processing, and data-driven machine learning methods, that are exploited for different applications such as speech, speaker and language recognition, very low-bit speech coding, biometrics (2D and 3D face, and voice), crypto-biometrics (including privacy preserving biometrics), and health applications.

The use of biometrics, and in particular the use of fingerprint recognition, is increasing day by day. Not only are we required (in European countries) to capture our fingerprints in order to obtain a passport, but we use them on a daily basis for other tasks such as unlocking our smartphones or confirming a bank transaction or payment.

In spite of the numerous benefits of utilising fingerprint recognition, some drawbacks come with this technology: one does not need to be a tech expert to carry out a presentation attack that may fool a system into believing you are someone else. Unattended capture devices need to have a Presentation Attack Detection (PAD) subsystem, to prevent such attacks.

The workshop raises awareness about this issue and about the current efforts of the biometric community in order to minimise the impact of such attacks. We will thus present a definition of the problem and provide the audience with possible solutions and a look into the future steps.

This workshop will feature presentations by experts from academic, industry, and governmental organisations and will facilitate interactions and discussions between the experts and the audience.

The European banking ecosystem is a hyper-regulated market, encompassing accounting policy, risk credit, and involving Agencies such as the EBA (European Banking Authority) in Anti-Money Laundering (AML) and counter-terrorism financing actions, on top of the overarching EU DG FISMA.

In parallel, banks are providing financial services that are composed mainly by three offers: banking account, payments means and loans. In this respect all main banks’ activities are impacted by European regulations and by the digitalisation of the society.

Biometrics is now a critical technology empowering several policies to make sure that any customers’ and prospects’ digital identity are secure when entering into:

• Purely on-line on-boarding or enrolment to a new account covered by the AML regulation, also known as “Know Your Customer”.
• Secure electronic authentication to your on-line banking account, covered by the PSDII directive.
• Secure electronic signature when subscribing to on-line services, covered by the eIDAS regulation.
• Secure contactless physical payments.

The event will be centred on policy, standard, technologies and business, around three pillars:

1. Digital Identity and biometrics in the banking world: the Policy landscape.
2. The Biometrics technology challenges of the digital Identity verification.
3. Focus on key topics and challenges.

The speaker roster will include officials from Governmental Agencies, Banking industry practitioners and well as Digital Identity and Biometrics experts. The program will include engaging with an expert panel on current challenges of digital identity verification.

Sagem mobiles introduced the fingerprints for mobile phones in 2010. The integrated fingerprint sensors on mobile phones have since inspired a wide variety of applications that include mobile banking. Despite the commercial success, the solutions were criticized in early stage for poor presentation attack detection algorithms. The subsequent generation of solutions have not only focused on the other biometric modalities such as face and ocular region, but have proposed better solutions for presentation attack detection and privacy protection. Today, a wide range of solutions are provided for presentation attack detection and privacy protection one can choose from.

This talk will present and discuss major milestones for biometrics on smartphones for banking applications. It will summarize the research achievements in the last decade, commercial success and few challenges to be addressed in near future. A particular focus will be given on approaches and solutions proposed within SWAN project (funded by Research Council of Norway) for various smartphone based biometric authentication in the light of banking applications.

Algorithmic decision systems have frequently been labelled as “biased”, “racist”, “sexist”, “unfair” by numerous media outlets, organisations, and researchers. Are such assessments justified? Should citizens and policymakers be concerned? What is the current state of the research? How can variation across demographic groups be quantified in evaluations of such systems? These and other related matters have recently become a hot topic in the context of biometric technologies, which are ubiquitous in personal, commercial, and governmental applications. Biometrics represent an integral component of many surveillance, access control and operational identity management systems, thus directly or indirectly affecting billions of people all around the world.

The EAB organizes a series of virtual events with “Demographic fairness in biometric systems” as an overarching theme. The events will feature presentations by experts from academic, industry, and governmental organisations and will facilitate interactions and discussions between the experts and the audience.

The goal of the events is to raise awareness, define the problem and propose solutions and possible next steps.

A white paper will be published based on the outcomes of the virtual events.

Workshop of the Biometrics Working Group of TeleTrusT, the IT Security Association in Germany

Deeply-learned face representations enable the success of current face recognition systems. Despite the ability of these representations to encode the identity of an individual, recent works have shown that more information is stored within, such as demographics, image characteristics, and social traits. This talk will show that many more soft-biometric attributes are embedding in face templates and that these attributes often have a strong correlation on the face verification performance.

Ten years back in spring 2011 our Norwegian Biometrics Laboratory (NBL) was established and for the opening we organized a workshop. Since then we have celebrated the NBL Annual Workshops (NBLAW). All the workshops are listed on the NBL homepage.

Our 10 years celebration will have a modest character due to the ongoing COVID-19 situation. But nevertheless we would like to (virtually) spend the day together with our friends and inform the public about the research that we conduct. Thus the theme of the NBLAW-2021 is "Face Morphing Attack Detection".

Widespread deployment of Automatic Border Control (ABC), along with electronic Machine Readable Travel Documents (eMRTD) for person verification, has enabled a prominent use case of face biometrics in border control applications. The trust anchor are biometric passports. Many countries issue eMRTD passports on the basis of a printed biometric face photo submitted by the applicant, a procedure which allows the possibility of the photo being either altered to beautify the subject’s appearance or morphed to conceal his/her identity. If an eMRTD passport is issued with a morphed facial image, two or more data subjects can then use it to pass a border control. This workshop will present discuss the morphing attack problem and indicate early solutions to detect such morphed facial images.

All times refer to CET.

In its first part the presentation will cover the increasing usage of live enrolment for German ID cards and passport since 2012: although live enrolment has not been made mandatory in Germany for a long time, Speed Biometrics GmbH has equipped over 100 local authorities (including more than 40 % of all large cities) in 11 federal states with over 180 Speed Capture systems during recent years.

The second part will deal with the attempt of the German Ministry of the Interior, Building and Community to make live enrolment mandatory and the resulting final law adopted by the German Bundestag end of 2020 (defining a dual approach allowing the applications to choose between a passport photo captured and transferred digitally by photographer and using live enrolment equipment at the authority where available).

The third part of the presentation will be dedicated to the (possible) consequences - challenges and chances - arising from the aforementioned law becoming effective 2025.

As such he is continuously working on improving the current solution to meet evolving technical requirements as well as customer demands. He has followed the legislative procedure resulting in the above mentioned law very closely.

The presentation will deal with the methods of fingerprinting, digitization and processing for the creation of fake fingerprints (PAD), the extraction of features (minutiae) and their use for generating synthetic fingerprints, including damage simulation. Last but not least, the fingerprint damage detection and its origin and overall quality estimation of the fingerprint will be mentioned.

The team of the Department of Multimedia Systems of the Gdańsk University of Technology in Poland has been working with the largest Polish bank in the field of biometrics since 2015. They have constructed an experimental multimodal biometric workstation replicated in 100 copies and installed in 60 branches of this bank. This workstation allowed them to conduct a large experiment in which they investigated the usability of different banking biometric modalities. The biometric system includes a biometric pen the team constructed to verify handwritten signatures, a camera and their proprietary facial recognition software, a microphone that works with an artificial neural network to verify the speaker, and a hand-vein sensor.

The team at GUT involved over 150 bank advisors and nearly 10.000 bank customers in the experiment. Also, they used surveys to gather opinions on the usefulness of the different types of biometrics. They have currently constructed an upgraded testbed, which has been extended with a scanner of ID documents and a gaze tracker, enabling contactless control of the whole biometric authentication process, and it also provides yet another biometric modality based on the analysis of saccadic movements.
