Incheon high-school student jailed for AI deepfake nude composites of his teachers posted online; a civil court later orders him to pay one teacher damages
In July 2024 a high-school student in Incheon, South Korea, composited the faces of two female teachers at his school and of others, including an academy senior and an instructor, onto nude photos and posted them on social media, according to the charges as reported by Yonhap, the Hankyoreh, the JoongAng Ilbo and the Kyunghyang Shinmun, which describe the technique as AI-based deepfake technology. He had also secretly photographed teachers in class. He was expelled after a teachers' rights committee hearing. On 27 August 2025 the Incheon District Court gave him an indeterminate prison term of one year to one year six months and took him into custody; the court said that as a result the victimised teacher had left teaching and had not returned. On 19 December 2025, after he had turned adult, the appeal division raised the sentence to three years, calling the offence close to 'character assassination' and the teachers' mental shock considerable; OBS reports the sentence is final. On 21 October 2026, according to the Incheon Teachers' Union, a civil judge at the Incheon District Court ordered him, now 20, to pay one teacher 17.7 million won of the roughly 72 million won she claimed.
