AI Summary

FakeBuster is a standalone deep learning-based tool for detecting deepfakes in video conferencing scenarios. It uses a 3D convolutional neural network trained on a diverse dataset to predict video segment-wise fakeness scores, offering a user-friendly interface for real-time detection.

Abstract

This paper proposes a new DeepFake detector FakeBuster for detecting impostors during video conferencing and manipulated faces on social media. FakeBuster is a standalone deep learning based solution, which enables a user to detect if another person's video is manipulated or spoofed during a video conferencing based meeting. This tool is independent of video conferencing solutions and has been tested with Zoom and Skype applications. It uses a 3D convolutional neural network for predicting video segment-wise fakeness scores. The network is trained on a combination of datasets such as Deeperforensics, DFDC, VoxCeleb, and deepfake videos created using locally captured (for video conferencing scenarios) images. This leads to different environments and perturbations in the dataset, which improves the generalization of the deepfake network.


Key findings
FakeBuster achieves an Area Under the ROC Curve of 90.61 on its test set. The tool provides a user-friendly interface for detecting deepfakes in real-time video conferencing, and it is independent of specific video conferencing platforms. Future work includes multiple face processing and model miniaturization.
Approach
FakeBuster uses a 3D ResNet-based visual stream architecture to analyze 30-frame video segments. The model predicts the probability of a segment being fake and the results are displayed in a time-series graph. The system also incorporates face detection and tracking.
Datasets
Deeperforensics, DFDC, VoxCeleb, and a custom dataset of 10,000 real and 10,000 fake videos created using Avatarify and locally captured images.
