Recently, the Xiamen police uncovered a case involving the use of AI technology to create fake videos. A 32-year-old man, Ren (from Hubei), was arrested for allegedly disseminating false information. Ren generated fake content and images and then created a video using AI technology, which he posted on Today’s Headlines. The video spread rumors about an elderly person being beaten in Guangdong and their grandson committing suicide by jumping into a river, attracting widespread attention. His aim was to increase followers and traffic for profit. Ren admitted that it only takes two to three minutes to create videos using AI technology. The police have taken criminal coercive measures against Ren; this incident serves as a warning.
