System and method for preventing phone fraud, mobile terminal and cloud terminal analysis server

Abstract

The invention provides a system for preventing phone fraud. The system comprises a mobile terminal and a cloud terminal analysis server. The mobile terminal is used for obtaining vocal print characteristics of the other communication party and the communication content of the other communication party in communication, and sending the vocal print characteristics of the other communication party and the communication content of the other communication party to the cloud terminal analysis server. The cloud terminal analysis server is used for comparing the vocal print characteristics with a pre-stored fraudster vocal print characteristic database and comparing the communication content with a pre-stored fraudster type database to determine whether the other communication party is a fraudster or not, and giving an alarm to a user of the mobile terminal through the mobile terminal when the other communication party is a fraudster. Through the system, the phone fraud is effectively avoided, and the probability that people are cheated is lowered. The invention further provides a method for preventing the phone fraud, the mobile terminal and the cloud terminal analysis server.
