摘要
根据关系数据库的特点,结合多维云模型,提出了一种半盲测的关系数据库云水印技术,给出了关系数据库多维云水印嵌入和提取算法.仿真实验表明该算法具有较强的鲁棒性和盲检性.
According to the feature of relational databases,combined with the multi-dimension cloud model,a partly blind testing cloud-water-marking technology of relational databases is put forward;besides,the multi-dimension cloud-water-marking embedding,detecting,and extracting algorithm of the databases are provided.Simulation experiments show a strong robustness and blind testing attribute of the algorithm.
