Abstract

The invention discloses a user verification method and device. The method comprises the following steps of: acquiring characteristic vectors from voice characteristic parameters extracted from voice signals of a user, wherein the voice characteristic parameters comprise linear prediction cepstrum coefficients, pitch periods, differential linear prediction cepstrum coefficients and / or differential pitch periods; calculating an average quantization error according to a pre-stored codebook quantization characteristic vector corresponding to the user; and determining whether the user passes voice verification according to the difference between the average quantization error and the pre-stored average quantization error corresponding to the user. The method provided by the invention can determine whether the user passes voice verification so as to quickly and reliably verify the identity of the user by processing the voice characteristic parameters extracted from the voice signals of the user and comparing the processed information with the pre-stored information, thereby improving system security in a login step.

Description

technical field [0001] The present invention relates to the field of cloud computing, and in particular, to a user authentication method and system. Background technique [0002] With the vigorous development of cloud computing, it has brought convenience to all walks of life, but many industry sectors use cloud computing less due to the consideration of the environmental security of cloud computing, especially some financial institutions that have extremely high requirements for information security. mechanism. However, verifying the user's identity during the login link can ensure the security of the cloud computing environment. Therefore, how to control the security of the cloud computing environment during the login link has become the focus of attention. Commonly used identification methods in the login link include passwords, fingerprint identification, etc. However, the use of human voice for identification has attracted more and more attention because of its unique ...
