Abstract

The invention discloses a fraud risk detection method based on a user node relation network. The fraud risk detection method comprises the following steps: acquiring related data of a user terminal; constructing a user node relation network based on the user terminal related data and the user attribute related data; and based on the user node relationship network, mining fraud related variables, and constructing a fraud risk detection model of the user. Therefore, the purposes of improving the fraud recognition rate and predicting the risk are achieved, and gang fraud is effectively recognized, and economic losses caused by the fraud risk can be reduced for companies.

Description

technical field [0001] The invention relates to the field of computers, in particular to a fraud risk detection method and device based on a user node relationship network. Background technique [0002] With the development and popularization of network technology, the financial industry combined with Internet technology is also showing a trend of rapid development, such as non-pure online credit platforms. With the help of Internet media, the transaction subjects of the pure online credit platform complete all or part of the business links online, such as information release, information acquisition, data filling, application submission, funding review, account binding, fund transfer, contract signing, etc., and finally realize the funds. accommodation. This model is different from the traditional credit model in that it reduces the dependence on physical outlets and offline labor, improves the efficiency of financing, and reduces the cost of financing. [0003] There are...
