摘　　要：针对目前没有测试基准对格式化文本水印算法鲁棒性进行评估和比较,提出了格式化文本水印性能评估基准。回顾了水印系统通用的框架,分析并确定了影响水印系统性能的参数和文本文档的视觉质量评级标准。借鉴图像水印性能评估基准的攻击分类,提出了Word特有的去除攻击、几何攻击、密码攻击和协议攻击的攻击分类方法,同时阐述了Word特有的攻击模式。对两种不同的文本水印算法进行了攻击强度—鲁棒性、攻击强度—视觉质量和嵌入数据量—鲁棒性测试,实验结果表明,该系统在文本水印算法评估和设计中具有有效性和实用性。Aiming at no available benchmarking to evaluate and compare the robustness of formatted text watermarking algo- rithms, this paper proposed a benchmark of formatted text watermarking. It reviewed the general framework of watermarking system, analyzed and determined the performance parameters of watermarking system and rating criteria of the text visual quali- ty. With reference of attack classifications of digital image watermarking performance evaluation benchmarks, it proposed a new classification of text watermarking attacks：removal attacks, geometrical attacks, cryptographic attacks and protocol at- tacks. Meanwhile., it also described the particular attack mode of Microsoft Word. Finally it tested two different text water- marking algorithms according to attack intensity-robustness, attack intensity-visual quality and amount of embedded informa- tion-robustness respectively. The experiment shows the system has the effectiveness and practicability in the evaluation and de- sign of text watermarking algorithm,
