| 摘 要： | 提出一种关系数据库水印算法,适用于数值型数据的版权保护.以连接多项式数组为密钥生成m序列,分别作为水印信号和水印嵌入策略控制信号;根据密钥和元组主键连接值的散列运算确定水印嵌入位置;通过修改数值属性低位数值的奇偶性嵌入水印,克服了常用的最低有效位重置算法易产生病态结果的缺点.水印的嵌入满足数据库动态更新的同步要求,水印的检测无需原始数据库参与.理论分析和实验表明,该算法运算开销合理,具有良好的隐蔽性和安全性,对常见的水印攻击具有良好的鲁棒性.

| Abstract: | An algorithm for relational database watermarking is proposed in this paper,and it is applicable to protect the copyright of numeric data.The m sequences are generated based on the secret key coming from a connection polynomial array,and are used for the watermark signal and the control signal for watermark embedding.The watermarking position is determined by the Hash operation of the bit catenation of the secret key and the primary key.The watermark is embedded into the numeric data by changing the parity ... |
