The Downfall of a Mosaic-Removal Business: Earning 11 Million Yen in 8 Months

In October 2021, the Kyoto Prefectural Police arrested a 43-year-old man from Hyogo Prefecture on suspicion of copyright infringement and the public display of obscene electronic data; he had been selling adult videos from which the mosaic blurring had been removed using “TecoGAN,” a commercially available AI image-processing software. The man operated a membership-based site where he processed videos upon customer request; reports indicate that in the approximately eight months leading up to his arrest, he had amassed around 200 members, processed some 12,000 videos, and generated sales totaling roughly 11 million yen.
