Fraudulent voiceprint acquisition device based on VOIP platform, and method, device and system for intercepting fraudulent telephone by using fraudulent voiceprint acquisition device

Abstract

The invention relates to the technical field of call security, and especially relates to a fraudulent voiceprint acquisition device based on a VOIP platform, and a method, device and system for intercepting a fraudulent telephone by using the fraudulent voiceprint acquisition device. The fraudulent voiceprint acquisition device based on the VOIP platform and the method for intercepting the fraudulent telephone by using the fraudulent voiceprint acquisition device can be implemented by a computer program stored in a computer readable storage medium by establishing functional modules and combining the functional modules into a functional module architecture. The fraudulent voiceprint acquisition device based on the VOIP platform can accurately acquire voiceprint features of a fraudster, construct a voiceprint library based on voiceprint information acquired by the device, and identify whether the fraudster exists in the call by using the characteristic that the voiceprint of different people is unique; and the method of identifying the fraudster through the voiceprint is more accurate than other methods for identifying the fraudster and an identification model is simpler, so that more convenient and effective fraudulent telephone interception can be achieved.

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, ...
