Researchers have developed new methods for verifying the authenticity of holograms on identity documents, particularly focusing on detecting dynamic fraud. One paper introduces a new dataset, MIDV-DynAttack, which triples the number of attack samples and proposes a novel verification method that can be trained without dynamic attack samples. The second paper presents two self-supervised approaches for verifying transparent Optically Variable Devices (OVDs) by modeling their temporal dynamics, which is crucial for defeating unknown attack types in open-set scenarios.
