摘要
为了实现针对数据库数据的泄密追踪,提出一套基于多层编码的数据库指纹溯源方法。在通过OFFO多层编码预防用户合谋的基础上在数据库中嵌入数据指纹,详细介绍指纹嵌入的基本原理与实现流程,通过提取码元的方式实现数据库指纹的溯源。最后通过数据库指纹匹配率对比实验的方式对溯源算法的有效性加以验证,实验结果表明,研究所提出的数据库指纹溯源方案在溯源准确率方面应用效果较为理想。
In order to realize the leak tracking of database data,this study proposes a set of database fingerprint traceability method based on multi-layer coding.On the basis of preventing user collusion through offo multi-layer coding,the data fingerprint is embedded in the database.The basic principle and implementation process of fingerprint embedding are introduced in detail.The traceability of database fingerprint is realized by extracting symbols.Finally,the effectiveness of the traceability algorithm is verified by the comparison experiment of database fingerprint matching rate.Through the experimental research,it is found that the database fingerprint traceability scheme proposed in this study shows an ideal application effect in the traceability accuracy.
