Transaction data processing method and device, equipment and storage medium

Abstract

The invention relates to the field of data processing, in particular to a transaction data processing method and device, equipment and a storage medium. The method comprises: obtaining a to-be-processed transaction data set which comprises transaction data of a plurality of transactions; performing account checking processing on the transaction data of the plurality of transactions to obtain an account checking result; when the account checking result is that account checking is successful, determining a target transaction party account of each transaction, and acquiring at least one target transaction party account; acquiring historical risk information, current transaction risk information and predicted risk information of the at least one target transaction party account; according to the historical risk information, the current transaction risk information and the predicted risk information, judging whether each target transaction party account is an abnormal account; and determining each piece of transaction data corresponding to the target transaction party account which is judged to be an abnormal account as abnormal transaction data. According to the method, the comprehensiveness and accuracy of transaction data processing can be improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a transaction data processing method, device, equipment and storage medium. Background technique [0002] With the development of Internet technology, online virtual resource transactions through the Internet are becoming more and more common. In order to ensure that the resources released by the resource party are used for real purposes or are not used illegally, it is necessary to audit the transaction behavior of online transactions and find abnormalities, such as whether resources are aggregated to a beneficiary account or composed of several beneficiary accounts group, whether the beneficiary account has device aggregation, whether the role of the beneficiary account is normal, etc. [0003] The transaction risk audit method in the prior art is based on the transaction data of the most end system, and some audit indicators are designed from the perspective o...

Problems solved by technology

[0004] The disadvantage of the existing technology is that it only uses the data of the terminal subsystem in the whole process of the transaction system, and does not use the data of each subsystem in the whole process of the transaction system, so it is impossible to avoid the audit blind spot caused by artificial data deletion of the terminal subsystem, and also It is impossible to detect the behavior of adding resources directly to the beneficiary's account by maliciously manipulating the transaction account; in addition, the existing audit method only uses the transaction data that has occurred for auditing, and the abnormal account in the actual risk is often a gang. The audit of the transaction data that has already occurred may not be able to find the abnormality of some accounts in the gang. Therefore, how to associate some accounts in the gang that have no abnormalities temporarily with accounts that have already had abnormalities in the gang will prevent possible occurrences in the future. Abnormal transaction data audited in advance has become an important problem to be solved
