Risk prevention and control strategy updating method and device

Abstract

One or more embodiments of the invention provide a risk prevention and control strategy updating method and device, and the method comprises the steps: carrying out the clustering of a plurality of business risk cases which are not recognized through employing a preset clustering algorithm, and obtaining a plurality of risk case clustering clusters; for each risk case clustering cluster, performing parameter threshold adjustment on a target risk control strategy matched with the risk case clustering cluster; if the adjusted risk prevention and control strategy meeting the preset disturbance permission condition exists, updating the initial risk prevention and control strategy according to the strategy adjustment result; and generating a new risk prevention and control strategy only if theadjusted risk prevention and control strategy meeting the preset disturbance permission condition does not exist. In this way, the risk control strategy can be updated automatically, the maintenance cost of the risk control strategy is reduced, the timeliness of risk control strategy updating is improved, and therefore the risk control strategy updating method can cope with stealing asset crime commissioning skills of related illegal persons more accurately, and then the identification accuracy of risk cases is improved.

Description

technical field [0001] One or more of this description relates to the technical field of risk identification, and in particular to a method and device for updating a risk prevention and control strategy. Background technique [0002] At present, with the rapid development of Internet technology, there are more and more Internet transactions. At the same time, there are certain transaction risks. In order to reduce the loss of users' funds, it is necessary to maintain a risk control strategy library. For each transaction request, based on Multiple risk control strategies in the risk control strategy library identify whether the transaction request is a risk transaction. Once a risk transaction is identified, it needs to be intercepted in time; avoid the risk screening of risk prevention and control strategies. [0003] Therefore, it is necessary for risk control personnel to re-establish corresponding risk prevention and control strategies based on their own experience based...

AI Technical Summary

Problems solved by technology

[0003] Therefore, it is necessary for risk control personnel to re-establish corresponding risk prevention and control strategies based on their own experience based on the newly discovered modus operandi and the common features of risk cases that have been missed, so as to deal with the latest modus operandi of criminals, thereby reducing the risk of missing cases. Screening rate; however, manual supplementary prevention of risk prevention and control strategies has the problems of low accuracy and strong lag, and depends on the experience of risk control personnel. In addition, as risk prevention and control strategies become more and more The more, the cost of policy maintenance also increases
