Deepfake
AI-generated synthetic media that replaces a person's likeness in existing images or videos, typically using deep learning techniques like GANs or diffusion models.
Technology
Deepfakes use face-swapping networks, voice cloning, and lip-sync models to create convincing fake media. Modern tools can generate photorealistic results from just minutes of reference material.
Detection and Ethics
Detection methods analyze facial inconsistencies, lighting artifacts, and frequency-domain signatures. The technology raises serious concerns about misinformation, non-consensual content, and trust in media. Many jurisdictions are developing deepfake legislation.
