Embodiment approach

[0110] In order to solve the above problems, the technical solution of this application provides a preferred implementation of calculating the difference: regularize the difference between the predicted value and the real value of the topological parameter to be evaluated, that is, not only consider the difference between the two, but also Consider the ratio of the two to eliminate or reduce the impact on the difference evaluation due to the difference in the value itself. Specifically, the following formula is used to calculate the difference between the predicted value and the actual value:

[0111] diff=(max(Ei,e*) / min(Ei,e*))×log(|Ei–e*|+1)

[0112] Among them, e* is the expected value of the topology parameter to be evaluated, Ei is the actual value of the topology parameter to be evaluated, and diff is the difference value after regularization processing.

[0113] After calculating the difference between the expected value and the actual value of the topology parameter t...

Abstract

The invention discloses a method for identifying risk in an object, comprising the following steps: generating a self-network of an object to be identified according to object behavior data, and acquiring the actual values of the topology parameters of the self-network; calculating the expected value of the topology parameter as a dependent variable by taking the actual value of the topology parameter as an independent variable as input according to the pre-generated constraint relation between the topology parameters; and judging whether the difference between the calculated expected value of the topology parameter and the acquired corresponding actual value is greater than a preset threshold, and determining that there is risk in the object to be identified if the difference is greater than the preset threshold. The invention further provides a device for identifying risk in an object. According to the method provided by the invention, risk identification is carried out according to the degree to which the topology parameters of the self-network of the object to be identified violate the global constraints from the perspective of the self-network of the object to be identified. A new judgment standard is provided for risk identification, and the risk control process is better.

Description

technical field [0001] This application relates to the field of risk control, in particular to a method for identifying object risks. The present application also provides a device for identifying the risk of an object. Background technique [0002] With the rapid development of network technology and network applications, the Internet has gradually penetrated into every corner of people's lives. Online reading, online video, and online social networking have become an indispensable part of people's lives. While the Internet brings convenience to people, it also provides a small number of malicious users with a platform for fraud and cheating. [0003] For example, in some network application systems, the operation behavior of most accounts is normal, but there are also a small number or individual accounts that use the network application platform to deposit funds, money laundering, cashing out and other fraudulent activities, as well as fraudulent activities such as embez...
