基于混合遗传算法的数据库水印算法研究

Study of Database Watermarking Algorithm Based on Hybrid Genetic Algorithm

将数字水印技术应用到数据库版权保护中,针对基于混合遗传算法的关系数据库水印算法实施了研究。结合标准遗传算法和禁忌搜索算法优点,克服了标准遗传算法易出现早熟以及局部寻优能力差等缺点,设计了数据库水印嵌入、检测及提取算法。

This digital watermarking technology will be applied to databases of copyright protection,in view of the relationship based on hybrid genetic algorithm to study the implementation of database watermarking.Combined with standard genetic algorithm and taboo search algorithm advantages of the standard genetic algorithm to overcome the premature and prone to poor local searching capability shortcomings,and designed the database watermark embedding,detection and extraction algorithm.
