Anti-fraud early warning system

Abstract

A fraud prevention and early warning system includes a database, a communication device, a processing device, and a mobile device electrically connected to the communication device. The processing device is electrically connected to the communication device and the database. An application on the mobile device inputs the content of a current communication into a voice and text recognition model for recognition to obtain text dialogue content. The system then obtains a keyword frequency and weight correspondence from the database via the communication device to determine multiple matching keywords and their frequencies in the text dialogue content. Based on this, it calculates the sum of four weights that meet the conditions to obtain a total weight value. When the mobile device determines that the total weight value exceeds a first predetermined threshold, it generates an alert signal to warn a user to avoid being scammed.
