> 中文摘要: 首先对按元素划分安全级的多级数据库上由函数依赖(FD)和多值函数依赖(MVD)引起的推理问题进行了研究,所提出的推理控制算法在很大程度上提高了数据的可用性.为进一步有效防范推理所导致的敏感信息泄露,给出了基于视图的推理控制方法.该方法能够处理多视图合谋带来的安全问题.最后给出了视图依赖基划分原理,它是以后有关视图推理控制的基础.

Abstract:This paper investigates the inference problems due to functional dependencies (FD) and multi-valued dependencies (MVD) in a multilevel relational database with element classification schemes. The algorithms presented can greatly improve the data availability. To further deal with the indirect privacy violation, the view-based inference control method is proposed which can eliminate the secure problem brought by multi-view collusions. The theories of splitting views into the view dependency basis are the foundation of future work on the view-based inference control.
