A risk monitoring method, device and electronic device for a target object

Abstract

Embodiments of the present specification provide a method, device, and electronic device for risk monitoring of a target object. The method includes: acquiring historical data generated by a target object within a predetermined time period, performing statistics on the historical data to obtain first historical time series data and second historical time series data; decomposing the first historical time series data to obtain a trend Feature data, periodic feature data, and random feature data, perform similarity calculation on the data in the second historical time series data to obtain a similarity value; perform forward difference between the trend feature data and the similarity value to obtain a similarity Differential results, and use anomaly detection algorithm to solve the abnormal situation score; calculate the characteristic variables of the abnormal situation score, periodic characteristic data and random characteristic data respectively, and perform weighted summation on the characteristic variables to obtain the target The risk score of the object, so as to realize the risk monitoring of the target object according to the risk score.

Description

technical field [0001] The present specification relates to the technical field of data processing, and in particular, to a method, device and electronic device for risk monitoring of a target object. Background technique [0002] With the rapid development of Internet technology and applications, various Internet services and platforms have emerged. In order to meet the regulatory requirements for these Internet services and platforms, risk monitoring technology has been widely used. Taking the Internet e-commerce field as an example, with the continuous popularity of e-commerce, China has become the world's largest e-commerce consumer market, and also has the world's largest online store. However, due to the weak online supervision and other characteristics of online e-commerce platforms, some merchants use online stores to conduct illegal acts such as pornography, gambling, fraud, and money laundering. These behaviors not only disrupt the market order, but also bring grea...
