摘要
数据库应用的快速发展需要水印数据库 ,这是数据所有权保护问题。首先介绍了云模型知识 ,然后提出了一种基于云模型的水印关系数据库技术 ,给出了关系数据库云水印嵌入和检测提取方法 ,并对实验结果进行了讨论分析。最后展望了水印关系数据库的前景和研究发展方向。
With the rapid development of the databases application, the watermarking database is needed, which involves dataproperty protection. The knowledge of cloud model is introduced firstly, and then a watermarking relational databases technology based on the cloud model is put forward. The methods of cloud watermark embedding, detecting and extracting are specified. And the experimental results are discussed and analyzed. Finally, some prediction are made of the foreground of the watermarking relational database and its research direction.
