Fraudulent voiceprint acquisition device based on voip platform and method, device and system for intercepting fraudulent calls using the device

Abstract

The present invention relates to the technical field of call security, in particular to a fraudulent voiceprint acquisition device based on a VOIP platform and a method and system for intercepting fraudulent calls by using the device. The method can be implemented by establishing functional modules, combining them into a functional module framework, and being implemented by a computer program stored in a computer-readable storage medium. The fraudulent voiceprint acquisition device based on the VOIP platform can accurately obtain the voiceprint characteristics of fraudsters, build a voiceprint library based on the voiceprint information acquired by the device, and use the voiceprints of different people as the only characteristic, it is possible to Whether there are fraudsters to identify, the method of identifying fraudsters through voiceprint is more accurate than other fraudster identification methods and the identification model is simpler, which can realize more convenient and effective fraud phone interception.

Description

technical field [0001] The present invention relates to the technical field of call security, in particular to a fraudulent voiceprint acquisition device based on a VOIP platform and a method and system for intercepting fraudulent calls by using the device. The method can be implemented by establishing functional modules, combining them into a functional module framework, and being implemented by a computer program stored in a computer-readable storage medium. Background technique [0002] VoIP is Internet telephony or IP telephony. It refers to a communication method in which analog voice signals are compressed and packaged, and then voice signals are transmitted over an IP network in the form of data packets. Because VoIP network phone can carry out free or very low-cost voice, fax, video and data transmission services under the Internet environment, while facilitating normal communication, it also makes the use of VoIP network phone to conduct fraud frequently. However, ...
