What is a deepfake?
Deepfakes are highly realistic, digitally manipulated videos or images where a person's likeness, voice, or actions are artificially created or altered using deep learning techniques, especially with neural networks. These tools can generate highly convincing media that appears real but is, in fact, synthetic. Deepfakes often use techniques like generative adversarial networks (GANs) to blend and map one person’s facial expressions or voice onto another, creating the illusion that the subject is saying or doing things they never did.
