Frequently Asked Questions
How can you detect a deepfake?
Detection tools analyze visual inconsistencies (eye blinking, face edges, reflections), audio artifacts, and file metadata. Platforms like Intel FakeCatcher and Microsoft Video Authenticator use AI to identify deepfakes in real time.
What's the difference between a deepfake and an AI-generated video?
A deepfake specifically impersonates a real existing person. An AI-generated video (like with Synthesia) creates original avatars or uses a person's likeness with their consent. The distinction lies in intent and consent.
