对数据库的安全防护进行介绍，着重对基于数字水印和基于触发器这两种数据库防护技术进行详细研究，并对两种方法在应用范围、实现难度、通用程度和技术差别进行比较，发现基于触发器技术在SQL Server数据库中性能优势明显，而基于数字水印的防护技术适用所有关系数据库，有广泛的应用范围。

On based of the security of the database are described, researched these two methods,that based on the digital water-marking and based on database triggers in detail, and compared the two methods in four aspects those the application, implemen-tation difficulty, common extent and technology.then found that Trigger-based techniques in the SQL Server database perfor-mance advantages are obvious, but protection technique based on digital watermarking is applicable to all relational databases with a wide range of applications.
