Abstract

The invention provides a voice copy and paste tampering detection method and system, and relates to the technical field of voice information processing. According to the method, relatively clean eGA-CQSD features in the CQSD features are extracted through a genetic algorithm with an elitist selection strategy, and interference information in CQSD features is removed, so that the accuracy of the detection result is less affected when the voice information is attacked by different forms of common attacks, namely, the accuracy of the voice copy and paste tampering detection method is improved when the voice information is attacked.

Description

technical field [0001] The invention relates to the technical field of voice information processing, in particular to a voice copy and paste tamper detection method and system. Background technique [0002] With the popularization of multimedia transmission equipment, voice signals are widely spread and applied in different fields. The convenience and entertainment of using voice signals bring a lot of fun to people's life, but there are also great potential safety hazards. Some criminals copy and paste the voice signal to destroy the authenticity and integrity of the original voice signal, causing the original intention of the speaker to be distorted, the details to be covered up, and even a forged voice to gain profits. Therefore, detecting whether speech has been tampered with by copying and pasting has become an important object for researchers in the field of information security. [0003] Existing methods for detecting whether speech has been tampered with by copying...
