DeepFake Detection System

Advanced AI-powered solution for detecting manipulated video content using CNN-LSTM hybrid architecture

90.17% Accuracy
150 Frames/Video
30 FPS Processing

Project Abstract

The rise of DeepFake technology poses a significant threat to the authenticity of visual media content. This project presents a novel approach for detecting DeepFake videos using a Convolutional Neural Network (CNN) enhanced with Long Short-Term Memory (LSTM) and ResNet50 architectures.

Leveraging the spatial and temporal features captured by CNNs, LSTM, and ResNet50, our model achieves high accuracy of 90.16% in discerning manipulated content. Through extensive experimentation on diverse datasets, we demonstrate the effectiveness of our approach in identifying subtle anomalies introduced by DeepFake generation methods.

The proposed detection system offers a scalable and efficient solution for real-time identification of DeepFake content in an era where visual media authenticity is of paramount importance.
