| 摘 要： | 针对机密数据库泄漏源检测问题以及现有技术存在的不足,提出了一种基于复合型数据库水印的检测方法与量化评估方案.设计了复合型数据库水印的添加与检测算法,利用水印添加与数据分发协议,将机密数据与其所有者和用户的身份绑定,实现了泄漏源检测与追查过程中对参与双方的公平保护.使用概率分析的方法实现了检测结果的可靠性量化评估.最后通过实验分析了算法的计算性能,验证了方案的有效性和可行性.实验结果表明该方案具有较高的实用价值.

| Abstract: | The problem of leakage identification for confidential database is a small-scaled pirate identification problem.After analyzing current solutions and their drawbacks,the author proposes a leakage identification and quantitative evaluation scheme for confidential databases,which is based on a compound database watermark technique.The principle of the novel database watermark technique and the watermark generation and detection algorithms are presented in the paper.By embedding a compound watermark in the dat... |
