Voiceprint signal processing method and device, storage medium and electronic equipment

The invention discloses a voiceprint signal processing method and device, a storage medium and electronic equipment. The method comprises the following steps: acquiring a first voiceprint signal in response to a voiceprint registration operation; performing feature extraction processing on the first voiceprint signal to obtain a first voiceprint feature; the first voiceprint feature is converted into a polynomial on an R ring, a first polynomial is obtained, and the R ring is used for indicating an algebraic structure comprising a plurality of polynomials; performing signature processing on the first voiceprint feature based on the first polynomial and the private key to obtain a signed voiceprint feature; and storing the signed voiceprint features in a database. According to the method and the device, the technical problem of low storage security during voiceprint registration and voiceprint feature storage in the prior art is solved. 本发明公开了一种声纹信号处理方法、装置、存储介质及电子设备。涉及金融科技领域，该方法包括：响应于声纹注册操作，获取第一声纹信号；对第一声纹信号进行特
