What best defines a deepfake?

• A. A real video of a public figure.
• B. Fabricated media created using AI that makes someone appear to say or do things they did not.
• C. A surveillance technique.
• D. A watermarking method for authenticity.

Answer: (B)

Deepfake refers to fabricated media created with artificial intelligence that makes someone appear to say or do things they did not. It often relies on advanced generative models, like neural networks, to synthesize realistic video or audio by convincingly simulating facial movements and speech. The key idea is deception: content that looks and sounds authentic but is not, which is why understanding deepfakes matters for media literacy and verification. The other options describe real content, a technique for surveillance, or a method for confirming authenticity, none of which capture the deceptive, AI-generated nature of deepfakes.
