<p class="MsoNormal"><span style="color:black">Dear colleagues,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black;mso-ligatures:none"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">We are excited to invite you to participate in the Dual Factor Lip-Based Biometric User Authentication Workshop and Challenge, which will be held in conjunction with ICIAP 2025.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">This event focuses on cutting-edge approaches to biometric authentication using a unique dataset of lip movement videos. Participants will develop systems that combine visual and audio cues — specifically, lip
dynamics and spoken passphrases — to verify user identity under open-set conditions. The challenge pushes the boundaries of multimodal biometrics, encouraging research in feature extraction, cross-modal learning, privacy-preserving AI, and robustness across
devices and conditions.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">The training set will be released on April 30, 2025, and the test set — available after abstract submission —will be released by May 20, 2025, at the latest. The final deadline to submit a paper to the workshop
is July 10, 2025.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">All accepted workshop papers will be published in a dedicated volume of the Springer Lecture Notes in Computer Science (LNCS) as part of the ICIAP 2025 proceedings.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">Top-performing teams will be invited to present their work at the workshop, and selected contributions will be invited to submit an extended version of their paper to the MDPI Applied Sciences Special Issue on
"Recent Advances in Biometrics and Multimodal User Authentication":<span class="apple-converted-space"> </span><a href="https://www.mdpi.com/journal/applsci/special_issues/XV7PJA0Y89" title="https://eur02.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.mdpi.com%2Fjournal%2Fapplsci%2Fspecial_issues%2FXV7PJA0Y89&data=05%7C02%7Cgeorgia.fargetta%40unict.it%7C45335612c7f14db6e7f608dd7d8856a2%7Cbaeefbc83c8b43829126e86bfef46ce6%7C0%7C0%7C638"><span style="color:#0078D7">https://www.mdpi.com/journal/applsci/special_issues/XV7PJA0Y89</span></a><o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:black"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:black">Submissions will be evaluated based on Equal Error Rate (EER) and authentication accuracy. Whether you are working on deep learning, computer vision, speech processing, or privacy-aware AI, this is an excellent
opportunity to benchmark your solutions and contribute to the development of secure, interpretable biometric systems.<o:p></o:p></span></p>
