Description

technical field [0001] The embodiments of this specification relate to the field of information security, and more specifically, to methods, devices, computing devices and machine-readable storage media for risk control. Background technique [0002] With the rapid development of information technology, the risk control of various businesses conducted on the network is becoming more and more important. For example, in the Internet financial scenario, risk control is usually carried out by formulating a series of standardized strategies, such as the baseline strategy for card replacement, the baseline strategy for changing Internet Protocol (Internet Protocol, IP) address attribution country, and so on.
