| 摘 要： | 通过对关系数据库特征的分析研究,归纳出数据库的数据特点。根据数据允许在一定范围内变形的特征提出相应的数据库水印模型,确定关系型数据库添加水印的方案。这种从非加密角度对数据库进行安全控制的新机制,实现了对敏感数据内容的安全性、完整性检查,并能对被攻击后的数据进行恢复,提高了数据库的安全可控性。

| Abstract: | Through deep analysis on the characteristics of relational database,it is found that data in a relation may be allowed to take transformations to some extent.A database watermark can be embedded into a database by executing data transformations.Database watermarking is a brand new security mechanism which is different from the traditional cryptography.It can not only ensure the security and integrity of sensitive data but also recover the attacked data.Therefore,the security control can be improved by datab... |
