Find the pirate
Japanese broadcaster NHK is installing hidden identifiers into its films to trace counterfeit copies over the Internet.
The system has been developed with Mitsubishi Electric and involves putting highly detailed electronic signals inside films that are invisible. If a person copies the film at a cinema or in front of a television screen, his or her camera will automatically tape the signal which will stay in the machine's memory.
It is then possible to find where the film came from and could help identify the pirate(s). The code can also help authorities trace the exact cinema and screening at which the person illegally taped a film.
