MIDV-DynAttack

MIDV‑DynAttack is the dataset for the paper "Verification of Dynamic Holographic Behavior in Identity Documents" accepted at the 19th International Conference on Document Analysis and Recognition (ICDAR 2025). This dataset addresses the remote verification of the authenticity of Optically Variable Devices (commonly known as holograms) on identity documents. Typically placed over the cardholder’s photo, these devices provide strong and easily verifiable security for human inspection but pose challenges for automated verification. Existing approaches easily cover static frauds (e.g., paper photocopy) and can be evaluated for such, but their capacity to detect real, dynamic fraud cases (e.g., handcrafted hologram) has not been evaluated to date because of the lack of public datasets. Furthermore, many systems are trained to detect known attack types, and few can generalize to new, unseen attacks. MIDV‑DynAttack is a new public dataset that extends the existing MIDV‑Holo dataset with realistic static and dynamic attacks against identity document specimens, tripling the number of attack samples compared to the original dataset. It is intended as a test‑only set of previously unseen attacks for evaluating the generalization and robustness of hologram verification methods. This record provides: video.tar.gz: 1200 newly captured videos (raw sequences for MIDV‑DynAttack). tracking.tar.gz: document localization coordinates for each frame sampled at 15 fps. cropped.tar.gz: rectified Regions of Interest (ROIs) containing part of the face and the main hologram, computed using the document localization.
