Embodiment 1
[0065] In the embodiment of the present invention, the associated transaction sequence determined by the transfer-out transaction corresponding to the transaction to be identified can be defined as a backward sequence. The backward sequence focuses on which subsequent transfer-out transactions the funds transferred into the transaction are used for. . For the transfer-out transaction in the backward sequence, the transaction time must be after the transfer-in transaction.
[0066] Specifically, the backward sequence of transactions in the account pool is determined through the following steps, such as image 3 Shown:
[0067] Step S301, initialize the backward sequence seq;
[0068] Step S302, arrange the transfer-in transactions in chronological order, and record them as the transfer-in transaction set L_IN;
[0069] Step S303, arrange the transfer-out transactions in chronological order, and record them as the transfer-out transaction set L_OUT. In an account pool, it can...
Embodiment 2
[0082] In the embodiment of the present invention, the related transaction sequence determined by the transfer-in transaction corresponding to the transaction to be identified can be defined as a forward sequence, and the forward sequence focuses on which transfer-in transactions the funds of the transfer-out transaction come from. The transfer-in transaction in the forward sequence must be earlier than the transfer-out transaction.
[0083] Specifically, the forward sequence of transactions in the account pool is determined through the following steps, such as Figure 4 Shown:
[0084] Step S401, initialize the forward sequence;
[0085] Step S402, arrange the transfer-out transactions in chronological order, and record them as the transfer-out transaction set L_OUT;
[0086] Step S403, arrange the transfer-in transactions in chronological order, and record them as the transfer-in transaction set L_IN;
[0087] Step S404, traverse L_OUT, record the current transfer-out tra...

Abstract
The invention relates to the field of financial science and technology, and discloses a method and device for determining an abnormal transaction, and the method comprises the steps: determining a transfer-out transaction corresponding to a to-be-identified transaction or a transfer-in transaction corresponding to the to-be-identified transaction according to the to-be-identified transaction after obtaining the to-be-identified transaction; determining an associated transaction sequence according to the roll-out transaction corresponding to the to-be-identified transaction or the roll-in transaction corresponding to the to-be-identified transaction; and determining whether the to-be-identified transaction is an abnormal transaction or not according to the associated transaction sequence and the to-be-identified transaction. Due to the characteristic of abnormal transactions that a plurality of transactions are transferred into one transaction and are transferred out or a large transaction is transferred out through a plurality of transactions after being input, whether abnormal transactions exist or not can be comprehensively determined through the transaction relation between the transactions and the transactions in the transaction sequence, and compared with the prior art, the method and device can determine whether abnormal transactions exist or not comprehensively and accurately.
Description
technical field [0001] The present invention relates to the technical field of financial technology (Fintech), in particular to a method and device for determining abnormal transactions. Background technique [0002] With the development of computer technology, more and more technologies are applied in the financial field. The traditional financial industry is gradually transforming into financial technology (Fintech). The processing technology for determining abnormal transactions is no exception. However, due to the security and real-time Sexual requirements, but also higher requirements for technology. [0003] In recent years, with the rapid development of the financial industry, especially the help of mobile Internet technology, the transaction volume of financial services has grown rapidly. Financial services are one of the important pillars of modern economic development, and the transaction scenarios of financial services are also more abundant. Financial transactio...
