基于遗传算法的关系数据库水印优化算法研究

提出了利用遗传算法在关系数据库海量的元组中选择最优元组进行水印嵌入,实现了水印短时间内的优化嵌入,大大提高了水印嵌入的效率。同时,采用纠错编码技术和投票选取机制来增加水印的鲁棒性。实验结果表明,这种关系数据库水印优化方案大大提高了水印嵌入的效率,并可以较好地协调水印的鲁棒性和数据库可用性之间的矛盾,实现了关系数据库水印的优化。

A Study of GA-based Relational Database Watermarking Algorithm

It proposed using genetic algorithm to select optimal turples from massive ones in which the watermark is to be embeded . Such program can significantly improve the efficiency of the watermark embedding. At the same time, the use of Error Correcting Coding Technique and majority voting mechanism to increase the robustness of the watermark. The experimental results show that this optimization program can effectively improve the anti-attack ability of watermark, and coordinate the conflict between the usabili...
