Recent discussions on privacy protection, for instance within the framework of the EU General Data Protection Regulation (GDPR), has raised privacy concerns regarding the storage and use of biometric data. The international standard ISO/IEC 24745 has established two main requirements for protecting biometric templates i) irreversibility and ii) unlinkability back in 2011. Since then, numerous efforts have been directed to the development and analysis of irreversible templates. However, until recently, a systematic quantitative manner to analyse the unlinkability of such templates was proposed. As a consequence, the lack of a unified framework to analyse all privacy aspects of biometric template protection schemes may have hindered their further deployment.

In this presentation, we will focus on the objective and quantitative evaluation of biometric template protection schemes. To that end, the main concepts related to template protection will be introduced, together with a review of the main existing approaches. A unified framework for the evaluation and benchmarking will be subsequently described, including the recently proposed unlinkability metric and some practical examples.

Curriculum vitæ

Marta Gomez-Barrero is a Professor for IT-Security and technical data privacy at the Hochschule Ansbach, in Germany. Between 2016 and 2020, she was a postdoctoral researcher at the National Research Center for Applied Cybersecurity (ATHENE) - Hochschule Darmstadt, Germany. Before that, she received her MSc degrees in Computer Science and Mathematics (2011), and her PhD degree in Electrical Engineering (2016), all from Universidad Autonoma de Madrid, Spain.

Her current research focuses on security and privacy evaluations of biometric systems, Presentation Attack Detection (PAD) methodologies, and biometric template protection (BTP) schemes. She has co-authored more than 70 publications, chaired special sessions and competitions at international conferences, she is associate editor for the EURASIP Journal on Information Security, and represents the German Institute for Standardization (DIN) in ISO/IEC SC37 JTC1 SC37 on biometrics. She has also received a number of distinctions, including: EAB European Biometric Industry Award 2015, Best Ph.D. Thesis Award by Universidad Autonoma de Madrid 2015/16, Siew-Sngiem Best Paper Award at ICB 2015, Archimedes Award for young researches from Spanish MECD, and Best Poster Award at ICB 2013.
