摘要: 针对数据仓库与在线分析处理(OLAP)系统存在的数据仓库非法访问和敏感信息间接推理问题,在原有统计数据库安全体系架构的基础上,构建OLAP的3层安全控制体系架构,并结合该架构提出一种新的基于数据立方体的推理控制方法。该方法先预防m维推理,然后清除一维推理,简化了m维推理的检测过程。

Abstract: Aiming at the problem of unauthorized access to data warehouses and indirect inferences of sensitive data in data warehouses and OLAP system, this paper builds a three-layer inference control architecture for OLAP based on statistical databases security architecture, and proposes a data cube-based inference control method implemented on the basis of the three-layer inference control architecture. This method prevents multi-dimensional inferences and then eliminates one-dimensional inferences, which simplifies the process of detecting multi-dimensional inference.

Key words: data warehouse, OLAP system, data cube, inference control, access control
