1.Definition
A deepfake is synthetic media created using artificial intelligence, where a person's likeness, voice, or actions are convincingly fabricated or altered. The term combines "deep learning" and "fake," referring to the neural network technology that makes these manipulations possible.
2.How It Works
Deepfakes typically use generative adversarial networks (GANs) or diffusion models. A generator network creates fake content while a discriminator network tries to detect flaws, and they improve together through this adversarial process. For face swaps, the model learns the facial structure and expressions of a target person, then maps those features onto another person's movements in video. Voice deepfakes similarly learn speech patterns to synthesize realistic audio.
3.Why It Matters
While deepfakes have creative and entertainment applications, they also pose significant risks for misinformation and fraud. Understanding how deepfakes work is essential for developing detection tools that protect individuals and organizations from manipulated media.
