| 摘 要： | 数字指纹系统是数字水印技术的一个重要分支，是用于盗版追踪的一种技术。离散指纹编码和连续指纹编码是数字指纹研究领域的两大阵营。本文介绍了嵌入假设对指纹编码研究的重要意义，指出这两种研究方向的主要分歧在于对待嵌入假设条件的态度不同。从嵌入假设条件出发分析了离散指纹编码和连续指纹编码的基本思路、面临的挑战和发展趋势。

| Abstract: | 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. |
