摘要
针对当前数据库存储信息的安全问题,提出一种基于模拟退火算法可逆数据库水印并对其进行实现,相关度技术的使用确定待嵌属性列,进一步利用模拟退火算法优化技术确定待嵌属性列数据的修改量,提高水印的不可见性;通过1位水印嵌入到数据块中,达到提高水印鲁棒性目的。测试结果表明,该系统能较好地实现数据库数据的版权和完整性保护。
Targetted at the current security database for storing information, we present the reversible watermarking database and its implementation based on simulated annealing algorithm. Correlation techniques are used to determine the attribute columns to be watermarked, and further simulated annealing algorithm optimization techniques are employed to determine the properties of the column data to be embedded modify. In this way, they help to improve watermarking invisibility. By embedding one watermark in the data block, we should improve the robustness of the watermark. Experimental results show that the system can achieve the better copyright and integrity protection of the database.
