Abstract:

Digital fingerprinting is a novel way for copyright protection of digital contents. A survey of digital fingerprinting is presented in this paper. First, the research background of digital fingerprinting is introduced, then the common model and basic requirements of fingerprinting schemes are summarized. Second, a brief overview of the encoding and tracing of digital fingerprinting is given, with some details on two typical fingerprint coding methods. Third, considering the evolution of digital fingerprinting protocols, the ideas of asymmetric and anonymous fingerprinting are introduced and the fundamental problems are analyzed. Moreover, some directions worth noting are pointed out.

Key words: digital fingerprinting, copyright protection, information hiding, non-repudiation, anonymity
