And all words in every set can be classified into two types. then according to the different types of the words, the words in every set are embedded into two watermark groups in a specific watermark embedding way, and their contents are associated with embedded watermarks. so during watermarking detection, the action that the attacker deliberately distorts or modifies the watermarking feature by extracting watermarks consciously or not can be found easily, and the text integrity detection performance can also be enhanced
按此思路，對全文2字元以上的單詞將它們分為3個集合（即3層）並將之作為水印嵌入對象，而每層的所有單詞又區分為2類，對每層的單詞按一種水印嵌入方式嵌入2組（次）水印，而對單詞嵌入水印信息的時候根據其類別的不同以不同方法嵌入，使水印的嵌入與單詞內容相關，以利於水印檢測時能夠發現某些情況下攻擊者有意或無意地保留水印而對文本內容進行刻意篡改或者直接修改水印特徵的行為，以增強文本完整性檢測的性能。
