Introduction

Deepfake technology uses advanced deep learning, especially Generative Adversarial Networks (GANs), to create highly realistic synthetic audio and video. In GANs, a generator creates fake content while a discriminator tries to detect whether the content is real or fake. Through continuous competition, the system produces deepfakes that closely resemble real media.

Although deepfakes have useful applications in industries such as entertainment, filmmaking, and virtual reality, they also pose serious risks. They can be misused for spreading misinformation, political manipulation, identity fraud, financial scams, and damaging reputations by impersonating public figures or creating fake speeches.

Detecting deepfakes is challenging because the technology continues to improve. Current detection methods include analyzing video frames for visual inconsistencies, examining mismatches in facial expressions and speech synchronization, and using deep learning models to identify patterns in manipulated content.

Many research approaches have been developed for detection, including systems using MTCNN, VGG19, EfficientNet, Capsule Networks, Bi-LSTM, ResNet-Swish, and Graph Neural Networks, which analyze both spatial and temporal features of videos.

The proposed deepfake detection system in this study works through several steps: data collection and preprocessing, feature extraction using InceptionV3, classification using CNN, RNN, and Capsule Networks, temporal analysis of facial movements, and final classification of videos as real or fake. This combination improves detection accuracy.

Experimental results show that the model performs well in detecting many deepfakes, but challenges remain. High-quality deepfakes, adversarial attacks, and computational requirements make detection difficult. Future improvements should focus on hybrid detection methods using audio-visual signals, transfer learning, explainable AI, lightweight models for real-time detection, and technologies like blockchain for media verification to ensure a safer digital environment.

Conclusion

The deepfake video detection model demonstrates promising accuracy, achieving around 81% training accuracy and 78% validation accuracy, though some uncertainty remains in classification. While it effectively differentiates real and fake videos, occasional misclassifications highlight the need for improvements in model architecture and dataset diversity. Future enhancements,suchasadvanceddeeplearningtechniques,better data augmentation, and real-world testing, can further refine its performance. Overall, the project establishes a strong foundation fordeepfake detection,with the potentialfor increased reliability through further optimization.
