摘　　要：对传统的数据库数字水印技术进行分析,结合关系数据库零水印一般模型,提出一种基于改进型C4.5算法的关系数据库零水印模型。重点研究该模型关系数据库零水印构建算法并进行定性分析,发现算法具有更广的适用性和更好的鲁棒性。We analyse the watermarking technology of traditional database and propose a zero-watermarking model for relational database which is based on improved C4. 5 algorithm in combination with general zero-watermarking model of relational database. The emphasis of the research is put on the zero-watermarking construction algorithm of relational database of this model and to carry out qualitative analysis. It is found that the algorithm has wider applicability and better robustness.
