摘　　要：文本数字水印是数字水印技术中的一个分支,好的数学模型可以增强水印的鲁棒性和安全性及效率等技术参数。在文本数字水印的应用中,基于非确定性数学模型的水印技术是一个分支,对该技术的性能进行了详细的分析和评估,指出了这种类型的数字水印的优劣和适用范围,为该类数字水印技术的实际应用提供了理论依据。Digital watermarking of text documents is a branch of digital watermarking. A good mathematical model can enhance some technique parameter such as robustness, security and efficiency of digital watermarking. The digital watermarking of text documents based on uncertain mathematical model is a branch of the application of the digital watermarking of text documents. The detailed analysis and evaluation of the performance of the technique is put forward, and its advantage, disadvantage and application area are pointed out. The theoretic basis of the practical application of the digital watermarking of text documents based on uncertain mathematical model is provided.
