Problems solved by technology

However, for gang fraudsters, the location of the crime is relatively fixed. Changing or increasing the location of the crime will inevitably increase the cost of the crime, and this part of the cost cannot be reduced through technical means. If the analog GPS point is used, the cost of the crime will be increased and it is easy be identified, so accurate GPS information can help us effectively identify where fraudulent transactions occurred

Abstract

The invention provides an order form fraud identification method and system based on a GPS (Global Positioning System), storage medium and electronic equipment. The method comprises the following steps that: according to the GPS coordinate distribution of a finished order form in a website, dividing a world map into a plurality of GPS grid positioning areas; in each GPS grid positioning area, independently obtaining historical order forms and recent order forms; in each GPS grid positioning area, calculating the information value of each feature variable; screening the feature variable of which the information value is higher than a preset threshold value, carrying out model training, and obtaining respectively independent fraud identification models which aim at each GPS grid positioningarea; and obtaining a new order form and the GPS ordinates in real time, positioning the GPS grid positioning area where the new order is positioned, and adopting the fraud identification model of theGPS grid positioning area to carry out fraud identification on the new order form. By use of the method for dividing the grid by the GPS coordinate, cost for using a traditional uniform model to carry out fraud identification is lowered, and identification ability for a fraud transaction which frequently replace user characteristics is enhanced.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a GPS-based order fraud identification method, system, storage medium and electronic equipment. Background technique [0002] Driven by the benign environment of "Internet +", the online ticket booking business continues to develop, and the products and services are becoming more and more diversified, resulting in more and more fraudulent activities. Criminals use stolen accounts and illegally obtained credit card information to purchase products on the website, causing losses to the website and other consumers. [0003] Under the existing technology, websites usually use rules / models to identify these fraudulent transactions, block fraudulent transactions without affecting the normal customer experience, prevent capital loss, and realize the protection of users' funds on the website platform. Improve users' sense of security in online payment. [0004] Through analysis, t...
