Deepfake Detection Project Guide

Deepfakes are synthetic media generated by AI, where faces are swapped or altered convincingly in videos and images. While they can be entertaining, deepfakes also pose serious threats like misinformation, political manipulation, and identity theft. Detecting deepfakes is crucial for safeguarding media integrity, requiring sophisticated models that analyze subtle artifacts in video frames such as inconsistencies in blinking, facial edges, lighting, and texture mismatches.

By using Convolutional Neural Networks (CNNs) and deep feature extractors, we can identify manipulated frames in videos. Techniques like frame-by-frame analysis, frequency domain examination, and facial landmark inconsistencies are key for training robust models. Models like XceptionNet and MesoNet, specifically tuned for deepfake detection, deliver state-of-the-art performance. This project blends computer vision, cybersecurity, and AI ethics — making it highly valuable and socially impactful.

The system processes each video frame through face detection and landmark extraction pipelines. CNN models analyze these frames to detect inconsistencies typical of deepfakes, such as unnatural blinking patterns, blurred boundaries, and lighting artifacts. Models trained on datasets like FaceForensics++ and Celeb-DF can generalize well to unseen deepfakes. Final predictions are aggregated across frames to determine the authenticity of the entire video clip, providing high confidence in classification.

• Collect labeled datasets like FaceForensics++, DeepFakeDetection Challenge Dataset, or Celeb-DF.
• Preprocess videos: extract frames, detect faces, crop to regions of interest, and normalize inputs.
• Train CNN models like XceptionNet, MesoNet, or ResNet variants for fake vs. real frame classification.
• Evaluate using metrics like Accuracy, Precision, Recall, ROC-AUC, and frame aggregation analysis.
• Deploy the system via a web interface allowing users to upload videos for deepfake detection and confidence scoring.
