Sony develops Protective AI to stop AI from stealing Studio Ghibli

Sony AI's research team announced the development of Protective AI (PA), a technology designed to prevent copyright infringement in videos and music generated by artificial intelligence. The system aims to create a mechanism so that creators and rights holders receive fair compensation when their work contributes to a generation.

A shield for Studio Ghibli

The tool was trained specifically on Studio Ghibli data to detect and reject imitations. According to Automaton, Protective AI is designed to prevent copying even through indirect prompts: the model receives the original material and is instructed to generate results that move away from that style.

The project also contemplates attribution and compensation for rights holders. Sony AI had already mentioned similar efforts in music, citing the experimental use of unlearning algorithms to measure how much each training example contributed to the generated output. Protective AI would apply a similar approach to video.

The initiative remains in the research and development phase. Sony has not yet adopted the technology internally nor announced a public release date.
