GBU-Palm: A Multimodal Video Dataset and Benchmark for Palm Presentation Attack Detection

Existing palm presentation attack detection (PAD) datasets are often limited by static imagery, restricted acquisition conditions, or insufficient multimodal video data, hindering systematic evaluation across environments, modalities, and attack types. We present GBU-Palm, a large-scale multimodal video dataset and ben...

FairForensics: Seeing Expressions and Parsing Demographics via Vision-Language Modeling for Generalizable Fair Deepfake Detection

A novel demographically balanced FDD benchmark is constructed to train and evaluate the fairness of detectors under both balanced and imbalanced population scenarios, and a novel expression and demographic perceptual vision-language model is introduced, termed FairForensics, for generalizable fair deepfake detection.
