Real-Time Spatio-Temporal Deepfake Detection for Live Biometric Authentication via EfficientNet-GRU
A highly optimized Two-Stream Spatio-Temporal architecture specifically designed for zero-latency live video evaluation, which extracts fine-grained spatial artifacts using a lightweight EfficientNet-B0 backbone, while a unidirectional Gated Recurrent Unit (GRU) models frame-to-frame physiological inconsistencies.
