Problems solved by technology

However, since the sound frequency range that the human ear can recognize is between 20Hz-20kHz, the "legal" frequency can be quickly found through the exhaustive method, resulting in a very low safety factor

Embodiment Construction

[0015] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the drawings, it should be understood that the disclosure may be embodied in various forms and should not be construed as limited to the embodiments set forth herein; A more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for exemplary purposes only, and are not intended to limit the protection scope of the present disclosure.

[0016] As mentioned above, current voice-based identity authentication schemes usually determine the user's identity based on the frequency of the voice to determine whether the authentication is successful. However, this authentication scheme has a low safety factor.

[0017] To address the above problems and other possible potential problems, embodiments...

Abstract

Embodiments of the present disclosure relate to a method, device, device and computer-readable storage medium for identity authentication. A method for identity authentication comprising: acquiring a sound signal of a user; generating feature data having multiple dimensions based on the sound signal, wherein the feature data of multiple dimensions indicates different characteristics of the sound signal; and based on The feature data is used to determine the identity of the user.

Description

technical field [0001] Embodiments of the present disclosure relate generally to identity authentication, and more particularly to methods, apparatuses, devices, and computer-readable storage media for identity authentication, especially sound or voice-based identity authentication. Background technique [0002] With the development of products such as smart speakers, voice-based authentication is becoming more and more important. However, at present, voice-based identity authentication methods are still at a relatively shallow technical level. For example, a common identity authentication method is an authentication method based on frequency (or sound frequency band). This method usually sets a set of audio ranges for each user. If the error of the received sound exceeds a certain threshold, the authentication will fail. If the received sound is in the same range as the user's audio, the authentication is successful. However, since the sound frequency range that the huma...
