数据流挖掘及其在持续审计中的可用性研究

随着企业信息化程度的提高和互联网的普及,每天都会产生海量的实时数据,而数据流挖掘则为分析海量数据提供了一种新途径。数据流挖掘中的聚类、分类、离群点检测等算法的研究取得了进展,为在持续审计中应用数据流挖掘提供了可行性。本文提出的一种基于数据流挖掘的持续审计模型,克服了传统持续审计模型对审计端的存储能力要求高、占用大量硬件资源、联机分析时间长、对异常数据的发现滞后等缺点。

Research on Data Stream Mining and Its Availability to Continuous Audit

With the development of enterprise informatization and the popularity of the Internet, massive real-time data are being produced every day. Data stream mining provides one novel approach to analyzing massive real-time data. In this paper the sate-of-art in this field is presented, and its availability to continuous audit is discussed. Finally, based on data stream mining, one continuous audit model is proposed, which overcomes the disadvantages of huge storage capacity requirements, long-time online analysis and the delayed finding of abnormal data.
