Competition Description

LivDet-Iris 2023 is the fifth competition in the LivDet-Iris series offering (a) independent assessment of current state of the art in iris Presentation Attack Detection algorithms and (b) an evaluation protocol, including datasets of spoof and live iris images, that can be followed by researchers after the competition is closed and compare their solutions with LivDet-Iris winners and baselines. LivDet-Iris 2023 has been included in official IJCB 2023 competition list.

This competition will have three parts:

Part 1: "Algorithms-Self-Tested" will involve the self-evaluation (that is, done by competitors on the sequestered and never-published-before test dataset) incorporating a large number of ISO-compliant live and fake samples. Samples will include irises synthesized by modern Generative Adversarial Networks-based models (StyleGAN2 and StyleGAN3) and near-infrared pictures of various artefacts simulating physical iris presentation attacks.

Part 2: "Algorithms-Independently-Tested" will involve the evaluation of the software solutions submitted by the competitors and performed by the organizers on a sequestered dataset similar in terms of attack types to the one used in Part 1.

Part 3: "Systems" will involve the systematic testing of submitted iris recognition systems based on physical artifacts presented to the sensors.

Competitors can participate in one, two or all parts. For each part a separate winner demonstrating the best performance will be announced. Metrics recommended by ISO/IEC 30107-1:2016 will be used to assess the submissions.

A summary of all previous LivDet-Iris competitions is available as a Chapter 7 in new Handbook of Biometric Anti-Spoofing, and this IJCB 2020 paper presents the most recent LivDet-Iris 2020 competition.

How to Participate

To participate in Part 1 -- "Algorithms-Self-Tested":

1. Obtain the self-evaluation package with the data
  • Execute these two data sharing license agreements and send them to the organizers (livdetiris23@gmail.com)
  • You will receive the details how to download the data package, which includes a small "train" dataset with correct labels (spoof/live) presenting the format and nature of the test data, and the actual "test" data, without ground truth labels, to be used in self-evaluation. This package will also include a short "readme" with instructions.
2. Generate self-evaluation PAD scores
  • Generate iris presentation attack detection (PAD) scores in the range of [0,100] for all of the “test” samples, where "100" is the maximum degree of liveness, and "0" means that the image is fake.
  • Construct the CSV file with two columns, “filename” and “score”, and put your PAD scores to this CSV. If the image cannot be processed, -1000 should be used as your PAD score.
3. Submit your CSV by April 15 23 (End of Day, Anywhere on Earth) to livdetiris23@gmail.com. Provide the following data (in the email) with your submission:
  • Submitter name: ____
  • Affiliation: ____
  • Email address: ____
  • Phone number: ____
  • Mailing address: ____
  • Acronym or short name of the team / solution: ____ (if you want to stay anonymous in the competition and all resulting publications, say “Anonymous”)
You will obtain the reception confirmation, or request to correct / amend the submission, if anything is incorrect. You are encouraged to submit early to let us screen your submission for potential errors.

Note 1: the "test" data CANNOT be used in any way for training your algorithms. We trust in your fair evaluation. You can use any publicly-available datasets for training, for instance the benchmarks from previous LivDet-Iris competitions, or datasets offered by the University of Notre Dame.

Note 2: Metrics recommended by ISO/IEC 30107-1:2016 will be used to assess all submissions: APCER at various levels of BPCER for the research paper, and average of APCER and BPCER to select the LivDet-Iris-2023 Part 1 winner (the 50.0 threshold will be used to calculate APCER and BPCER error rates in this case).


To participate in Part 2 -- "Algorithms-Independently-Tested":

Follow these instructions to submit your executables by April 15 23 (End of Day, Anywhere on Earth). Provide the following data (in the email) with your submission:
  • Submitter name: ____
  • Affiliation: ____
  • Email address: ____
  • Phone number: ____
  • Mailing address: ____
  • Acronym or short name of the team / solution: ____ (if you want to stay anonymous in the competition and all resulting publications, say “Anonymous”)
Optionally, if you find it useful, you can request a copy of "train" and "test" data from Part 1 (see above for how). The LivDet-Iris team will process the executable application file on the sequestered datasets of similar nature (however with possibly different attack types) as the data offered in Part 1. Important: the "test" data offered in Part 1 CANNOT be used in any way for training your algorithms.


To participate in Part 3 -- "Systems":

You will need to have your iris recognition system submitted to Clarkson University, NY, USA. Please contact us at your earliest convenience at livdetiris23@gmail.com to arrange the logistics of this testing.

Winners and IJCB Paper Submission

Winners: Each Part (1, 2 and 3) will have its separate winner. Metrics recommended by ISO/IEC 30107-1:2016 will be used to assess the submissions. For Parts 1 and 2 the 50.0 threshold will be used to calculate APCER and BPCER error rates.

Competition Results - Part 1
The results of the competition are as follows:
In first place was team BUCEA, with a best ACER of 0.071.
In second place was team Fraunhofer IGD, with a best ACER of 0.209.
In third place was team HDA/IDVisionCenter, with a best ACER of 0.260.
The full breakdown of the competition results will be available in the IJCB paper described below.

IJCB Paper Submission: At least all winners (from all categories) will be invited to co-author the IJCB paper submission. Depending on the number and quality of submissions (e.g., when the performance between the winners and runner-ups is small), we will extend this invitation to the authors of other well-performing algorithms and systems, to make the resulting paper useful for the community and the participants.
