Effective and Efficient Collusion-Resistant Fingerprinting for Multimedia (ISR IP)

ISR intellectual property available to license

Inventors: Shan He, Min Wu

Digital fingerprinting is an effective method to identify users who might try to redistribute digital content, such as music, images, video and software. These fingerprints are typically embedded in the content using watermarking techniques that are designed to be robust to a variety of attacks. A cheap and effective attack against digital fingerprinting is collusion, where several differently marked copies of the same content are combined to disrupt the underlying fingerprint. It is therefore important to design fingerprints that are not only able to resist collusion, but also identify the colluders.

This invention facilitates the protection of the multimedia by providing a proactive tracing ability against collusion attack. It will prevent illegal redistribution in commerce and/or discourage information leaking from government and the military.
