Abstract
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, ...
Examples
Embodiment Construction
[0038] In order to realize the interception of fraudulent calls, the fraudulent voiceprint library is first obtained from the fraudulent voiceprint. When judging whether a fraudster is involved in a call, the voiceprint of the audio of the current call is compared with the fraudulent voiceprint database. If there is a voiceprint that matches the voiceprint of the audio of the current call in the fraudulent voiceprint library, it is determined that a fraudster has participated in the call, and the current call is a fraudulent call.
[0039] When constructing a fraud voiceprint database, on the one hand, the voiceprints of fraudsters collected by public security organs can be stored; Deploy a fraudulent voiceprint acquisition device based on the VOIP platform on the backbone network, first eliminate a large number of non-VOIP-related network data packets on the network, and leave useful data packets for voiceprint capture and restoration; then split the RTP voiceprint data, Fina...
