BeGuard: An LSTM–Fused Defense Model Against Deepfakes in Competitive Activities–Related Social Networks

International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.
We propose a novel defense mechanism for protecting users from deepfakes by analyzing their behaviors in competitive activities and their social interactions. The model dynamically embeds user behaviors based on their participation in competitive activities, capturing these activities’ temporal dynamics through long short–term memory networks.
