FAQs Frequently Asked Questions Topics Deepfake Detection Liveness Detection Facial Recognition Deepfake Detection Find answers to your most common questions in our FAQ section. What are deepfakes? Deepfakes are synthetic media (usually videos, images, or audio) created using artificial intelligence to realistically replace or mimic a person’s likeness or voice. What are the principles of deepfakes? They rely on AI models, mainly deep learning and generative adversarial networks (GANs), which learn patterns of facial expressions, movements, and voices to generate or swap identities convincingly. What are some common types of deepfakes? There are four widely known types of deepfakes, which are: Face swapping (replacing one face with another in videos or images) Lip-syncing (altering mouth movements to match new audio) Voice cloning (synthetic replication of a person’s voice) Full-body puppetry (animating a person’s entire body) What techniques are used in deepfake creation? There are many techniques used for deepfake creation, but the most common are: GANs (generator-discriminator framework for realism) Autoencoders (encoding and decoding facial features for swaps) Neural rendering (enhancing realism with refined AI-based adjustments) 3D modeling & motion capture (for complex facial or body movements) What is the difference between deepfake and shallow fake? Deepfakes use AI to create highly realistic synthetic media, while shallow fakes use simple edits (cropping, splicing, speed changes) without AI. What are the security risks associated with deepfakes? They enable identity fraud, phishing scams, reputational attacks, market manipulation, and misinformation campaigns. How can deepfakes impact my business? They can damage brand reputation, erode customer trust, trigger financial losses, and expose the organization to fraud or regulatory penalties.
