摘要：

　　With the widespread use of watermark in video,audio and image,propose a relational database based watermark embedding and extraction method.The algorithm utilizes the single—multiple mapping approach to plug in watermark,which scatter the distribution of watermark information and enhance the anti-attack ability of the algorithm.The experiments show that the method enjoys strong robustness to such attacks as tuples resorting,subset selection and so on.
