AI - Powered DeepFake Detection
Executive Summary
In an era of rapid AI advancement, hyper-realistic deepfakes pose a serious threat to digital trust. We developed a powerful Deepfake Detection API using a state-of-the-art NVIDIA Hive detection model with a FastAPI backend. The service securely analyzes uploaded images and returns high-confidence results - specifying whether each detected face is “real” or “fake” along with a confidence score and bounding box. This solution automates deepfake identification with high accuracy, addressing the urgent need for reliable and scalable visual content verification.
Challenges
Solution Overview
Our solution uses a lightweight, stateless FastAPI backend to orchestrate deepfake analysis. The client sends an image via a POST /detect request to the backend. The backend uploads the image to NVIDIA’s secure Asset service and receives a unique assetId. It then invokes the NVIDIA Hive Deepfake Detection API with that assetId. The model analyzes all faces in the image and returns a JSON response containing face classifications, confidence scores, and bounding box coordinates. Finally, the backend forwards this structured JSON back to the client. No images are stored on our servers, ensuring user privacy and a minimal data footprint.
How it Works
Client Request:
The user selects an image and sends a POST request to the /detect endpoint of the FastAPI service.
Secure Upload:
The backend uploads the image to NVIDIA NIM’s Asset API, receiving a unique assetId.
Model Invocation:
The backend invokes the NVIDIA Hive Deepfake Detection API using the assetId.
Model Analysis:
The EfficientNet-B4 + YOLOv8 model analyzes each detected face, classifying it as real or deepfake and computing a confidence score.
Receive Results:
The NIM service returns a detailed JSON with predictions (face class, confidence, bounding box).
Return to Client:
The backend immediately forwards this JSON response back to the client.
Supported Image Formats
JPG and PNG images (up to 10 MB) are supported. Common image formats like JPEG and PNG are accepted for analysis.
