A voiceprint recognition attack defense method based on cuckoo search algorithm

Abstract

A voiceprint recognition attack defense method based on the cuckoo search algorithm, including: (1) preparing the original audio data set; (2) training the voiceprint recognition model: using the pre-trained data set to train the voiceprint recognition model, and then using Test data set to test the accuracy of the recognition model; (3) Attack the voiceprint recognition model: build an attack method based on the cuckoo search algorithm, set the fitness function and related parameters of the attack method; use the attack method to generate the optimal adversarial sample, Make it be misidentified as the target category and not be recognized by the human ear; (4) confrontation training voiceprint recognition model: add the samples generated in step (3) to the pre-training data set, retrain the voiceprint recognition model, so that the new The trained voiceprint recognition model has the ability to defend against adversarial sample attacks, improving the security and stability of the voiceprint recognition model.

Description

technical field [0001] The invention belongs to the field of deep learning algorithms and information security research, and in particular relates to an attack defense method for a voiceprint recognition system based on a cuckoo algorithm. Background technique [0002] As a biometric technology, voiceprint recognition can effectively distinguish the voices of different people by extracting the unique features of the speaker's voice. Since the speech containing voiceprint features is easy to obtain, and the recognition algorithm complexity is low, the voiceprint recognition system has a wide range of applications. The existing voiceprint recognition technology is divided into text-related and text-independent. The text-related voiceprint recognition model requires the user to pronounce according to the specified content. The voiceprint model of each person is accurately established, but the recognition must also follow the specified content. Pronunciation can achieve a bette...

Problems solved by technology

[0005] The present invention overcomes the security problem that the existing voiceprint recognition system is vulnerable to attack by adversarial samples, and provides a voiceprint recognition attack defense method based on the cuckoo search algorithm, which can efficiently generate adversarial samples to make the recognition system misidentify, And use the way of confrontational training to add the generated confrontational samples into the original training data set. The voiceprint recognition model after confrontational training can defend against the attack of confrontational samples and has higher security.
