The dangers of deepfakes
Deepfakes are AI-generated videos or images in which someone's face or voice is imitated. They are becoming increasingly realistic and the risks are growing rapidly.
What are deepfakes?
Deepfakes are synthetic media in which AI realistically imitates the face, voice, or body of a person. The name combines 'deep learning' and 'fake'. The technology has improved dramatically — what previously required hours can now be done with a smartphone app in minutes.
How do deepfakes work?
Deepfakes use Generative Adversarial Networks (GANs) or diffusion models. A generator creates fake synthesis; a discriminator tries to distinguish fake from real.
The dangers
- Disinformation
- Election manipulation
- Fraud — CEO fraud via fake voice
- Intimidation — non-consensual intimate imagery
- Reputational damage
Detection
AI detection tools look for inconsistencies: strange eye movements, odd hairlines, inconsistent lighting. It is an arms race.
What can you do?
- Be skeptical of shocking video evidence — check the source
- Companies: train employees to recognize deepfake fraud
- The EU AI Act prohibits certain applications of deepfakes
