Researchers have developed a new deepfake detection method that analyzes both facial movements and physiological signals like heart rate. By constructing high-fidelity deepfakes on existing rPPG datasets, they found that manipulations disrupt natural physiological cues and facial behavior. Their proposed bidirectional co-attention fusion detector effectively captures these cross-level dependencies, achieving high AUC scores on constructed datasets and demonstrating applicability to other deepfake benchmarks.
