Abstract: In order to better identify the fraud against large amount insurance, this paper summarizes the main risk types of large amount insurance, and defines the main construction direction of large amount insurance anti fraud system. A big data intelligent anti fraud system model for large amount insurance is proposed based on Apriori algorithm, focusing on the analysis of data statistical identification, insurance fraud rule mining, insurance fraud behavior identification. Empirical operation of the constructed big data intelligent anti fraud system for large amount insurance shows that the system based on Apriori algorithm can quickly complete the effective identification of the fraud behaviors against large amount insurance.

大額保险是指投保的保险金额相对较大的人身保险,通常保险金额是在50万以上,投保时需要对其实施契约调查,充分掌握投保人的资产情况,明确投保人的投保动机,身体健康情况等[1]。近年来,在中国经济飞速发展的影响下,国内保险行业迅速崛起,为广大社会群体提供了健康保障。大额保险作为保险行业非常重要的一类产品,具有“避债、避税、传承”的作用,成为了高净值人士投资理财的热门选择,这使得大额保单量持续增加,保额也在不断攀升。
本文拟根据大额保险的特点,基于关联规则挖掘算法的经典算法Apriori算法,设计一套具有较高可行性的反欺诈系统,期望以此降低保险运营成本,营造一个良好的保险行业环境。
