The Japanese government is mulling plans to stamp out music piracy on mobile handsets, according to a report in the Daily Yomiuri. It could come into force early next year, and is due to be discussed this month at a meeting with the RIAJ and the Japanese mobile operators’ association. The plan will apparently involve checking song IDs when users download them over the air, to make sure they’ve been distributed legitimately. If not, the user will get a warning, while the download will either be terminated, or rendered unplayable on their handset. It’s certainly a first technology-wise – and is aimed at reducing the 400 million songs downloaded illegally every year by Japanese mobile users.
