Abstract

An anti-fraud system that utilizes association rules of fraud as well as AFS (Anti Fraud System) for credit card payments in e-commerce is proposed. The association rules are found by applying the data mining algorithm to millions of transaction records that have been generated as a result of orders on goods through the Internet. When a customer begins to process an order by using transaction components of a secure messaging protocol, the degree of risk for the transaction is assessed by using the found rules. More credit information will be requested or the transaction is rejected if it is interpreted as risky.

인터넷상의 전자상거래 주문에서 발생하는 수백만건의 트랜잭션 레코드들에 대해 Hybrid 기법으로 데이터마이닝 기술인 연관규칙 탐사기법과 AFS (Anti Fraud System) 를 활용하여 전자상거래 과정에서 흔히 일어날 수 있는 부정 거래를 최소화할 수 있는 새로운 전자결제 신용카드 사기방어시스템을 제안한다. 고객이 웹 상의 거래 콤포넌트에 의한 보안 메세징 프로토콜을 사용하여 거래를 시도하면 과거 트랜잭션 데이터를 이용하여 미리 생성해 둔 사기성 거래에 대한 연관규칙의 적용으로 거래의 위험도를 판단하여 위험도가 높다고 판단될 경우 부가적 신용 정보를 요구하거나 거래를 중단하는 시스템이다 본 시스템의 장점은 기존의 사기방지시스템 보다 빠른 응답성과 그에 따른 효율성을 들 수 있다.
