摘    要:提出一种基于混沌变换的关系数据库水印算法,将混沌变换引入数据库水印处理,根据数值属性权重的不同嵌入水印。将水印算法与混沌理论相结合,隐蔽性更强,提高了水印的不可见性,同时水印检测是一个盲检测过程,实验表明,该算法具有较强的鲁棒性和良好的不可见性

关 键 词:关系数据库水印  混沌变换  版权保护  鲁棒性

Abstract:An algorithm based on chaos transform for relational database watermarking is proposed in this paper,which uses the encrypted images sequence as watermarks and embeds them into the database according to the weight of attributes.The combination of the watermarking technology with the chaos theory improves the invisibility of watermarks.And watermark detection is blind.Experimental results show that the proposed scheme has good invisibility and robustness against various forms of attacks
Keywords:relational database watermarks  chaos transform  copyright protection  robustness
