Business level - credit card
In recent years, the national online shopping demand has grown rapidly, and the demand for online shopping during the epidemic was also one of the reasons, resulting in a substantial increase in the amount of credit card fraud.
According to the data of the National Credit Card Center of R.O.C, the amount of stolen credit cards in China in 2021 will be 1.96 billion, and the accumulated amount of stolen credit cards from January to September 2022 will reach 1.583 billion, and it is expected to exceed 2 billion by the end of the 2022.
Taking 2021 as an example, if the detection rate of credit card theft is increased by 1%, the loss of 19.6 million yuan can be reduced.
Real-time detection of fraudulent credit card behavior can greatly reduce the cost and loss of financial industry investigations, and also improve customer confidence and satisfaction due to real-time detection of fraudulent credit card behavior.
Through the 1H3A abnormal behavior detection method, a credit card network transaction fraud (fraud) detection model is built on the original early warning system, which can achieve enhanced fraud (fraud) transaction judgment information, improve risk control, and reduce risks.
