关系数据库中实时嵌入水印算法的研究

Research on Real-time Embedding Watermark Algorithm for Relational Databases

在研究现有关系数据库水印技术的基础上,提出了一种可以实时嵌入数据库水印的算法,通过控制因子控制水印嵌入位置,采用移位嵌入法重复嵌入水印,大大提高了抗攻击性.实验表明该算法具有较强的鲁棒性和实时性.

Based on current relational database watermark technology, a database watermark algorithm with real-time embedding is put forward. This algorithm controls watermark to embed position based on controling factor, and it adopts the position-moving embedding to embed watermark again, raising the ability of resisting important attacks. By experimentation, the algorithm is proven to be very robust and real-time.
