Biometrics provides efficient and reliable solutions to recognize
individuals. With increasing number of identity theft and miss-use
incidents we do observe a significant fraud in e-commerce and thus
growing interests on trustworthiness of person authentication.
Nowadays we find biometric applications in areas like border control,
national ID cards, e-banking, e-commerce, e-health etc. Large-scale
applications such as the upcoming European Union Entry Exit System (EES),
the Visa Information System (VIS) and Unique Identification (UID) in India
require high accuracy and also reliability, interoperability, scalability
and usability. Many of these are joint requirements also for forensic applications.

Multimodal biometrics combined with fusion techniques can improve
recognition performance. Efficient searching or indexing methods can
accelerate identification efficiency. Additionally, quality of captured
biometric samples can strongly influence the performance. Moreover,
mobile biometrics is an emerging area and biometrics-based
smartphones can support deployment and acceptance of biometric
systems.

However, concerns about security and privacy cannot be neglected.
The relevant techniques in the area of presentation attack detection
(liveness detection) and template protection are about to supplement
biometric systems, in order to improve fake resistance, prevent potential
attacks such as cross matching, identity theft etc.

The BIOSIG 2021 conference addresses these issues and will present
innovations and best practices that can be transferred into future
applications. The conference is jointly organized by the Competence
Center for Applied Security Technology (CAST), the German Federal
Office for Information Security (BSI), the European Association for
Biometrics (EAB), the TeleTrusT-Association, the Norwegian Biometrics
Laboratory (NBL), National Research Center for Applied
Cybersecurity (ATHENE), the Fraunhofer Institute for Computer
Graphics Research IGD, IET Biometrics Journal and the special
interest group BIOSIG of the Gesellschaft für Informatik e.V. (GI). The
conference proceedings will be submitted to the IEEE Xplore Digital
Library®.

We invite stakeholders and technical experts to submit original research
papers. Industrial contributions presenting lessons learnt from practical
usage, case study, recent results of prototypes, are also welcomed.
We plan to organise the conference as hybrid event with on-site activities and
options for remote participation.
