摘要
数字水印主要用于数字作品的版权保护。解释攻击是数字水印攻击的主要手段之一．详细介绍了如何利用时戳机制、公证机制、单向水印机制来对抗解释攻击，以及各种解决方案优劣特性。并在此基础上，提出了一种能够较好抵抗解释攻击的数字水印模型．该模型能够避免由于解释攻击引起的无法仲裁的版权纠纷的出现，并允许版权所有者在一个比较宽松的环境下为作品添加水印。
The main purpose of digital watermark is copyright protection of digital work. Interpretation attack is one of the main attack methods for digital watermark In this article, we present how to use timestamp mechanism, notarization mechanism and one way watermarking mechanism against interpretation attack. After trying to study the essential characteristic of interpretation attack and comparing the advantage and disadvantage of each resolution, we propose a watermark embed scheme against interpretation attacks. This model will avoid the copyright disputes from interpretation and allow an author embed the watermark for his works in a free environment.
