Abstract :
To protect intellectual property and distribution rights against dishonest customers in the multimedia content market, fingerprinting schemes that use error-correcting codes help identify users illegally redistributing media. This article presents a traitor-tracing algorithm that takes advantage of soft-decision decoding techniques to find all identifiable traitors.
