Deepfake detection
Deepfake detection is the analysis of digital media to determine whether it has been synthetically generated or manipulated.
Introduction to Generative AI, Second Edition
Deepfake detection is the analysis of media to determine whether it has been artificially generated or manipulated.
- How it is used
- Deploys media analysis as one component of responding to increasingly convincing synthetic content.
- How deep it goes
- Explains indicators, generalization failures, adversarial adaptation, and layered responses without implementation detail.
- Examples
- Uses biometric and logical indicators, metadata, provenance checks, visual or auditory analysis, and Community Notes as examples.
- What you can do after
- Evaluate manipulated media cautiously and apply detection alongside provenance, authentication, and collaborative verification.

Deepfake detection is the analysis of digital media to determine whether it has been synthetically generated or manipulated using machine-learning methods.
- How it is used
- Deploys binary image classification to distinguish real faces from AI-generated faces.
- How deep it goes
- Explains dataset preparation, preprocessing, transfer learning, validation, inference, visualization, and accuracy, without developing ResNet50 from scratch.
- Examples
- Uses real and AI-generated face grids, ImageFolder datasets, DataLoaders, predicted labels, and a 93.73% test-accuracy calculation.
- What you can do after
- Build it from scratch by fine-tuning ResNet50 to classify unseen face images as real or fake and evaluate its test accuracy.
