Abstract

The invention provides a risk prevention and control processing method and device and an apparatus. The method comprises: generating a target risk prevention and control model of the target service based on the risk transaction data and the non-transaction risk data identified by the current risk prevention and control model of the target service and the characteristic variable data generated by the current risk prevention and control model in the risk identification process; carrying out on-line test on the target risk prevention and control model, and carrying out stability evaluation on thetarget risk prevention and control model in the process of on-line test; if the target risk prevention and control model satisfies a predetermined stability evaluation condition, updating the currentrisk prevention and control model using the target risk prevention and control model.

Description

technical field [0001] This specification relates to the field of computer technology, and in particular to a method, device and equipment for risk prevention and control. Background technique [0002] With the increasing popularity of network technology and terminal technology, there are more and more risks in online transactions. Although there are risk prevention and control rules in business systems such as online transactions, the risks of online transactions have not been reduced. Business systems Risk prevention and control in China still faces huge challenges. [0003] Business systems usually have a risk prevention and control system based on risk data. Currently, the training of risk prevention and control models is achieved through training sample data, and the training sample data is based on T+1 historical data cleaned from offline databases. Since the historical data lags behind in time, this will cause the risk prevention and control model trained based on th...
