摘要
该文针对含有数值型属性的多属性关系数据库,描述了一个能对关系数据库进行版权保护的水印算法RDWA,该算法通过在数值型属性中嵌入水印信息,能将水印广泛地散布到数据库中,并且实现了多个属性间的关联嵌入和提取。实验表明,该算法具有很强的鲁棒性。
This paper describes an algorithm which can protect the copyright of an relational database,which has mutiple attributes including numeric attributes.The algorithm can scatter an watermark broadly in the database through inserting watermark information in numeric attributes,and realize the associated insertion and detection of mutiple attributes.The algorithm is very robust as an experiment proved.
