Korean Court Acquitted a Man Who Bought Deepfake Idol Images. The Law Couldn't Prove They Were Real.
A South Korean court acquitted a man in his 20s who purchased deepfake nude images featuring the face of a teenage K-pop idol, ruling on June 8 that prosecutors failed to establish the images depicted a real person. The First Criminal Division of the Daejeon District Court's Cheonan Branch, presided over by Judge Jo Young-jin, found the defendant not guilty on charges of violating Korea's Act on the Protection of Children and Juveniles from Sexual Abuse.
The defendant, identified as Mr. A, purchased a photo - a woman's nude image with a female celebrity's face composited onto it - for 20,000 won (approximately $15). Prosecutors charged him under the Act, which prohibits purchasing, possessing, or viewing sexual content that clearly depicts or can clearly be recognized as depicting a child or adolescent. The court found that without documentation of the image's original source, compositing method, or production chain, it could not conclude with certainty that the face in the image belonged to a real person. The judge stated there was insufficient basis to determine "whether the victim actually exists."
The defense argued the image may have depicted an AI-generated fictional person rather than a real individual - a claim prosecutors could not definitively refute. The court accepted this reasoning.
Legal commentators were quick to clarify the ruling's boundaries. Attorney Bae Hee-jeong of law firm RoYu said the verdict does not mean deepfake sexual crimes go unpunished, but rather that when prosecutors apply the child protection statute, they must separately prove the composite image "can be clearly recognized as depicting an actual child or adolescent." Images not meeting that burden may still face prosecution under other laws.
The practical implication is harder to dismiss. AI image generation has reached a quality threshold where the question of whether a face is real or synthesized can no longer be resolved visually. That's the evidentiary gap this ruling exposed: a law designed to protect real people from sexual exploitation now requires proof of realness that advances in synthetic media make increasingly difficult to establish. South Korea ranks as the country most targeted globally by deepfake pornography - K-pop singers and actresses accounted for 53 percent of individuals featured in deepfakes according to a 2023 report by US cybersecurity firm Security Hero. The legal infrastructure protecting them is now running a step behind the technology generating the harm.
South Korea passed a revised law in late 2024 significantly strengthening penalties for deepfake sexual content creation and distribution. Whether the purchasing side of that equation can be prosecuted under the revised statute, when the images themselves cannot be verified as real, remains an open question this verdict didn't answer.
