abstract = {Identifying missing persons over long time intervals is a critical application of biometric systems, but facial aging poses a major challenge for recognition accuracy. In this paper, we propose a comprehensive AI-driven framework that integrates deep face embedding with age-progression modeling and fast similarity search to mitigate the effects of age variation. We employ a state-of-the-art face embedding network (ArcFace) to extract discriminative features, and augment the reference database with synthetic aged face images generated by a conditional adversarial autoencoder. Retrieval is performed with Facebook AI Similarity Search (Faiss) for efficient nearest-neighbor matching. Our experiments on benchmark aging datasets demonstrate that incorporating age-progressed faces significantly improves identification accuracy and F1-score (e.g., a ~3% accuracy gain over baseline) for large age gaps[1][2]. The proposed system effectively retrieves the correct identity despite age differences, illustrating its potential for aiding long-term missing person searches.},
