| 摘 要： | 为了检测对关系数据库的恶意篡改,提出了一种脆弱性数字水印算法,该算法将数据库的元组划分到不同的分组中,在对分组内的所有元组进行秘密排序的基础上,生成由属性水印和元组水印构成的分组水印矩阵,从而可以将对数据库的篡改定位在分组范围内.理论分析和实验结果表明了该方法的有效性和可行性.

| Abstract: | A fragile watermarking algorithm was proposed to detect malicious modifications of relational databases.In the proposed algorithm, all tuples in relational databases were divided into different groups,and by sorting secretly the tuples in each group, group watermarking matrix made up of attribute watermark and tuple watermark was generated for localizing modifications of relational databases in a group. Theory analysis and experimental results show that the effectiveness and feasibility of the proposed method. |
