Protecting copyright is one of the hottest topics in information and media technology at the moment. Digital technology enables perfect copying on amateur equipment. Digital Fingerprinting is an emerging technology to protect multimedia from unauthorized redistribution. It embeds a unique ID into each user's copy, which can be extracted to help identify culprits when an unauthorized leak is found. Thereby any emerging illegitimate copy can be traced back to the guilty party. A major challenge is to make this system secure against coalitions of pirates.
