Abstract

The embodiment of the invention provides a transaction data verification method and device, a medium and an electronic device. The method comprises the following steps: at least one first cluster center is obtained by clustering the obtained transaction data at a first level; According to a risk verification result of the first cluster center and a cluster in which the number of objects in the first cluster center is larger than a preset value as a target cluster for further verification; At least one second clustering center is obtain by performing a second hierarchical clustering on that target cluster; the at least one second cluster center is verfied to complete verification of the transaction data. The technical proposal of the embodiment of the invention can reduce the verification times of the transaction data, save the verification cost and improve the verification efficiency under the condition that a large amount of transaction data exists. At the same time, it can improve the accuracy of transaction data verification.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a transaction data verification method, device, medium and electronic equipment. Background technique [0002] With the development of Internet technology and the popularity of online shopping, more and more people are keen on online shopping and use online payment to complete data transactions. However, this online transaction mode cannot guarantee the security of the transaction. Therefore, the transaction data needs to be verified to ensure the security of the transaction. [0003] In the existing technology, the verification of transaction data is generally done by waiting for user feedback on whether there is a decision to let go or intercept by mistake, or after random sampling of transaction data, the verification is completed through manual inspection, resulting in a faster transaction data verification. Slow and less accurate. [0004] Therefore, the ac...
