Abstract

The embodiments of the invention provide an illegal transaction detection method and an illegal transaction detection device in order to solve the problem that there still lacks a detection method which can be used to detect a specific transaction behavior of a user directly at present. The method comprises the following steps: acquiring the current transaction behavior data of a user; extracting first continuous index data and first discrete index data from multiple behavior indexes of the current transaction behavior data; calculating a first probability of the current transaction behavior according to the first continuous index data and a continuous detection model, and calculating a second probability of the current transaction behavior according to the first discrete index data and a discrete detection model, wherein the continuous detection model and the discrete detection model are determined according to historical transaction behavior data; and getting a third probability according to the first probability and the second probability, wherein the third probability is the probability that the current transaction behavior is an illegal transaction. An analysis is made of a specific transaction behavior of a user, and whether the transaction behavior of the user is legal or not is distinguished based on the characteristics of the transaction behavior of the user. Thus, the precision of detection is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to an illegal transaction detection method and device. Background technique [0002] Proxy access technology is widely used because it can enhance the user's online security, save network resources and many other advantages, but it also brings certain problems to the security management of transactions. [0003] In the existing proxy access detection technology, it is commonly used to capture the user's access data packets at the network layer, and judge by analyzing the data packets, or use commonly used proxy ports to perform reverse proxy scanning, and also through comparison Proxy Internet Protocol Address (Internet Protocol Address, IP) library to identify proxy access, however, most of these detection technologies focus on the identification of the network protocol layer, which not only requires a long detection delay, but can only identify whether the user is a proxy IP,...
