Abstract

The embodiment of the invention provides an identification method for a high-risk transaction subject. The identification method comprises the following steps: constructing a transaction relation network by utilizing transaction data information; and according to related data in the transaction relationship network, calculating the probability that an unknown high-risk transaction subject is a high-risk transaction subject through a known high-risk transaction subject in the transaction data information, thereby identifying a new high-risk transaction subject. Therefore, more high-risk transactions can be effectively and timely identified by an e-commerce platform or a third-party payment company and the like, possible loss is prevented or reduced, normal operation of company services is guaranteed, and normal market order is maintained.
