Digital fingerprinting is reported and used in copy tracing. It embeds different information, for example, Customer ID, into multimedia content, produces a different copy, and sends the copy to the corresponding customer. If a copy is spread to unauthorized customers, the unique information in the copy can be detected and used to trace the illegal distributors. In this chapter, we introduce some digital fingerprinting algorithms, review the existing traitor tracing schemes, analyze the performances of some typical algorithms through comparison, and propose the future trends and some open issues in this field. It is expected to provide some valuable information to researchers or engineers working in mobile multimedia security.
