Digital Fingerprinting System and Marking Assumption
数字指纹编码与嵌入假设

Digital fingerprinting, an active area of digital watermarking, is designed to trace pirate. Discrete fingerprint and continuous fingerprint are two different branches in this area. The main divergence between them is their attitude to marking assumption, which is an important assumption in discrete fingerprint designing. From the view of marking assumption, the development and trend of both research branches are analyzed.
