DeepID challenge aimed to advance the research in the methods for detecting synthetic manipulations in ID documents. For that purpose a FantasyID dataset of both bona fide and manipulated fantasy ID cards was provided to the participants for training and tuning of their systems. Participating submissions were evaluated on a test set of FantasyID card created with both seen and unseen attacks, and on an out-of-domain private dataset of 20K real ID documents containing both genuine bona fide and manipulated samples. The challenge included two tracks 1) a binary detection track to detect whether an ID document is manipulated or not and 2) a localization track, where the goal was to identify the manipulated regions of an ID document. The evaluations were based on the F1-score metric for both detection and localization track and the submissions were ranked based on the weighted average F1-score of FantasyID (with weight 0.3) and private (with weight 0.7) test sets. With more than 100 registrations in the challenge, 26 teams have participated and 6 of them managed to beat the provided TruFor baseline method in detection track and 4 teams in the localization track. Sunlight team from Sun Yat-sen University has won both tracks of the challenge and UAM-Biometrics has ranked best in the private dataset.
