A Novel Multi-Scale Spectral-Guided Graph Attention Network for DeepFake Video Detection

The rapid advancement of deepfake technology presents significant challenges for video authenticity verification, necessitating robust detection mechanisms. This paper introduces a novel framework for deepfake video detection that integrates the Multi-Scale Spectral-Guided Graph Attention Network (MSG-GAT) with the Lightweight Assimilation-Elimination (Lite-ASEL) algorithm. By representing video frames as graphs, the framework effectively captures intricate pixel relationships, enabling the detection of subtle manipulations with enhanced precision. Additionally, the Lite-ASEL algorithm is employed for feature selection, balancing reduced computational complexity with high detection performance. Experimental results demonstrate the superiority of the proposed framework, achieving state-of-the-art performance with an AUC of 99.1 % and a detection accuracy of 99.3%. Furthermore, hyperparameter tuning confirms the framework's robustness and efficiency, consistently achieving an optimal objective score of 98.54%, validating its effectiveness for optimal feature selection and deepfake detection.
