A deepfake is a type of artificial intelligence technology that creates realistic-looking fake videos or audio recordings. It uses machine learning algorithms to analyze and mimic the appearance and voice of real people, making it seem like they are saying or doing things they never actually did. This technology can be used for entertainment, such as in movies or video games, but it also raises concerns about misinformation and privacy. The term "deepfake" combines "deep learning," a subset of artificial intelligence, and "fake." While it can be used creatively, it poses risks, especially when used to create misleading content that can harm individuals or influence public opinion. As a result, many are calling for regulations to address the ethical implications of deepfake technology.
