Deepfake

Deepfakes are synthetic media created using AI technology that realistically replaces a person's face, voice, or movements with those of someone else. The name is a portmanteau of "deep learning" and "fake," and refers to highly sophisticated video or audio forgeries. This technology works by learning from large quantities of video and audio featuring real individuals, then generating realistic content that makes it appear as though those individuals are speaking or acting in ways they never did. Facial expressions, mouth movements, and vocal tone can all be replicated with such precision that humans may be unable to tell the difference. Core technologies involved: • Video synthesis using GANs (Generative Adversarial Networks) • Voice cloning via voice conversion and text-to-speech (TTS) • Face swapping and lip sync processing Legitimate use cases of deepfakes include: • De-aging actors or creating stand-ins in films and commercials • Controlling expressions and narration for virtual characters • Enhancing immersion in educational or entertainment content At the same time, malicious uses — including the spread of fake videos impersonating politicians or celebrities, defamation, identity fraud, and the amplification of misinformation — pose serious social risks. In response, deepfake detection technologies and legal and ethical frameworks are being developed in various countries. Balancing the advancement of generation technology with safeguards against misuse is a critical challenge going forward.
