Abstract

The invention relates to the field of computers, and discloses an automatic classification method and a device for transaction accounts. In the present invention, among the plurality of accounts to be classified, at least one account is known as the first type of account, at least one account is known as the second type of account and the type of at least one account is unknown; the method includes the following steps: The flow of transaction funds between accounts establishes an update network; for each type of unknown account in the update network, the computer repeats the following steps at least once: obtain the transaction flow information of the adjacent account of the current account in the update network; according to the acquired The information on the flow of transaction funds selects adjacent accounts with transaction funds flowing to the current account; the type of the current account is updated according to the type of the selected adjacent accounts. The invention takes the flow direction of funds into account update considerations, can improve the classification accuracy of account types, and at the same time, reduce the amount of calculation and improve the classification efficiency of the computer.

Description

technical field [0001] The invention relates to the field of computers, in particular to the automatic classification technology of transaction accounts. Background technique [0002] With the rapid development of computer technology, more and more people participate in online transactions, and various third-party payment systems or platforms have emerged. However, there are many risk problems in the current Internet third-party payment platforms. Especially in card theft and account theft cases, these two types of theft have brought great challenges to the security experience of customers and the safe operation of payment institutions. [0003] At present, the mining of criminal gangs in online transactions generally adopts the method of collecting homogeneous cases from hundreds of thousands of cases, using clustering based on environment, account or bank card. For example, a set of cases can be obtained by capturing cases with the same environmental characteristics of th...
