Abstract

The invention discloses a fraud behavior detection method, which comprises the steps of collecting a to-be-detected sound signal, and executing a fraud keyword recognition operation on the to-be-detected sound signal to obtain a fraud keyword recognition result; determining the number of fraud keywords contained in the sound signal to be detected according to the fraud keyword recognition result; judging whether the number of the fraud keywords is greater than a preset value or not; and if yes, judging that the fraud behavior is detected. According to the invention, the fraud behavior is detected based on the sound content, and the success rate of fraud behavior detection can be improved. The invention further discloses a fraud behavior detection device and a storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of information security, and in particular to a fraud detection method, a fraud detection device and a storage medium. Background technique [0002] Bill fraud, financial voucher fraud, credit card fraud and other fraudulent activities will cause great physical and mental losses to the victims. With the rapid development of communication technology, there have also been non-contact frauds implemented by communication tools such as fixed telephones, mobile phones, and the Internet. [0003] At present, telecommunications fraud is mainly detected by fraudulent phone numbers or IP addresses used in fraudulent fraud. However, since telephone numbers and IP addresses are easy to change and hide, the success rate of the above-mentioned method of detecting fraudulent behavior is relatively low. [0004] Therefore, how to improve the success rate of fraud detection is a technical problem that those skille...
