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.</div>

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.</div>

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.</div>

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.</div>
