意味

Deepfake — AI-generated fake media, especially manipulated video or audio that makes someone appear to say or do something they never did.

Borrowed from English 'deepfake' (deep learning + fake), this term describes AI-manipulated media that is increasingly difficult to distinguish from reality. In Japan, awareness grew particularly around concerns about celebrity and politician deepfakes, as well as non-consensual intimate imagery. The term carries strongly negative connotations and is primarily used when discussing the dangers of this technology.
