In this chapter, the digital fingerprinting technology that is used to trace illegal distributors in multimedia content distribution is investigated. Firstly, the background and basic knowledge of digital fingerprinting- based multimedia distribution are reviewed. Then, some existing fingerprinting algorithms are introduced and compared. Additionally, the methods to embed the fingerprint securely are overviewed and analyzed. As an example, the secure audio distribution scheme is presented, and its performances are evaluated. Finally, some open issues and the future trends in digital fingerprinting are proposed. It is expected to provide valuable information to the students, engineers or researchers interested in this research topic.
In secure multimedia distribution, multimedia content is transmitted from the sender to the receivers in a secure manner. Generally, two techniques are used to protect multimedia content’s ownership and confidentiality respectively, i.e., digital watermarking and multimedia encryption.
