We invite competition proposals for the 2023 International Joint
Conference on Biometrics (IJCB 2023) in Ljubljana, Slovenia. The main
goal of the competitions is to provide a common ground for benchmarking
of state-of-the art algorithms, to consolidate research and identify
open problems in biometrics-related research areas. We solicit
competition proposals on any topic of interest to the broader biometric
community and strongly encourage proposals focusing on new emerging
fields and open research questions that are able to attract a
significant number of participants. Competition organizers having a
strong track record in the field are especially welcome.
 From the proposals received, the strongest will be selected to be held
with IJCB 2023 and eventually invited to submit summary papers to the
conference. The selection process will be based on the novelty of the
proposed competition, the relevance and timeliness of the problem
explored, the importance of the research questions investigated, the
potential to attract a large number of competitors, the impact of the
competition, and the track record of the organizers.
The deadline for submitting competition proposals is Monday, February
6th, 2023. Decisions will be circulated by February 14th, 2023.

the competition, which will be linked from the conference web site. The
web-site should be online before the start of the competition.

*** Proceedings and Presentation ***
Competition organizers will be invited to submit a summary paper
discussing organization, datasets, and results by May 15th, 2023. The
summary papers will be considered for inclusion in the IJCB 2023
conference program and should follow the same formatting and
presentation rules as regular papers. The submissions will undergo the
same review process as regular papers. The presentation format (if
accepted) will be determined based on the quality of the submission and
reviewer feedback received. Accepted summary papers will be included in
the proceedings of IJCB 2023 and send for inclusion in IEEE Xplore.
