+# DeepSecure-AI
+
+DeepSecure-AI is a powerful open-source tool designed to detect fake images, videos, and audios. Utilizing state-of-the-art deep learning techniques like EfficientNetV2 and MTCNN, DeepSecure-AI offers frame-by-frame video analysis, enabling high-accuracy deepfake detection. It's developed with a focus on ease of use, making it accessible for researchers, developers, and security analysts...
+
+---
+
+## Features
+
+- Multimedia Detection: Detect deepfakes in images, videos, and audio files using a unified platform.
+- High Accuracy: Leverages EfficientNetV2 for enhanced prediction performance and accurate results.
+- Real-Time Video Analysis: Frame-by-frame analysis of videos with automatic face detection.
+- User-Friendly Interface: Easy-to-use interface built with Gradio for uploading and processing media files.
+- Open Source: Completely open source under the MIT license, making it available for developers to extend and improve.
+
+---
+
+## Demo-Data
+
+You can test the deepfake detection capabilities of DeepSecure-AI by uploading your video files. The tool will analyze each frame of the video, detect faces, and determine the likelihood of the video being real or fake.
+
+Examples:  
+1. [Video1-fake-1-ff.mp4](#)
+2. [Video6-real-1-ff.mp4](#)
+
+---
+
+## How It Works
+
+DeepSecure-AI uses the following architecture:
+
+1. Face Detection:  
+   The [MTCNN](https://arxiv.org/abs/1604.02878) model detects faces in each frame of the video. If no face is detected, it will use the previous frame's face to ensure accuracy.
+
+2. Fake vs. Real Classification:  
+   Once the face is detected, it's resized and fed into the [EfficientNetV2](https://arxiv.org/abs/2104.00298) deep learning model, which determines the likelihood of the frame being real or fake.
+
+3. Fake Confidence:  
+   A final prediction is generated as a percentage score, indicating the confidence that the media is fake.
+
+4. Results:  
+   DeepSecure-AI provides an output video, highlighting the detected faces and a summary of whether the input is classified as real or fake.
+
+---
+
+## Project Setup
+
+### Prerequisites
+
+Ensure you have the following installed:
+
+- Python 3.10
+- Gradio (pip install gradio)
+- TensorFlow (pip install tensorflow)
+- OpenCV (pip install opencv-python)
+- PyTorch (pip install torch torchvision torchaudio)
+- facenet-pytorch (pip install facenet-pytorch)
+- MoviePy (pip install moviepy)
+
+### Installation
+
+1. Clone the repository:
+        
+    cd DeepSecure-AI
+    
+
+2. Install required dependencies:
+        pip install -r requirements.txt
+    
+
+3. Download the pre-trained model weights for EfficientNetV2 and place them in the project folder.
+
+### Running the Application
+
+1. Launch the Gradio interface:
+        python app.py
+    
+
+2. The web interface will be available locally. You can upload a video, and DeepSecure-AI will analyze and display results.
+
+---
+
+## Example Usage
+
+Upload a video or image to DeepSecure-AI to detect fake media. Here are some sample predictions:
+
+- Video Analysis: The tool will detect faces from each frame and classify whether the video is fake or real.
+- Result Output: A GIF or MP4 file with the sequence of detected faces and classification result will be provided.
+
+---
+
+## Technologies Used
+
+- TensorFlow: For building and training deep learning models.
+- EfficientNetV2: The core model for image and video classification.
+- MTCNN: For face detection in images and videos.
+- OpenCV: For video processing and frame manipulation.
+- MoviePy: For video editing and result generation.
+- Gradio: To create a user-friendly interface for interacting with the deepfake detector.
