Problems solved by technology

[0004] However, the disadvantages of this traditional voiceprint verification scheme are: the accuracy of voiceprint verification is greatly affected by the quality of the voiceprint data, which can easily lead to errors in identity verification results; it is vulnerable to human voice intervention and voice hijacking during voice collection , it is impossible to accurately control the timeliness and authenticity of voiceprint verification, and the security cannot be guaranteed

Embodiment approach

[0044] As an implementation manner, the step of analyzing the user's first-type answer to the first-type question according to a predetermined first analysis rule specifically includes: acquiring the first-type answer input by the user to the first-type question; Comparing the first type of answer with the standard answer, identifying the part of the difference, and determining the difference value of each preset difference type in the difference part; according to the mapping relationship between the predefined preset difference type and the preset difference threshold, the The difference value of each preset difference type in the difference part is compared and analyzed with the corresponding preset difference threshold, and the verification analysis result is output.

[0045] The preset difference types include the number of difference parts, the number of error bits, the degree of interval difference, and the degree of interval matching. For example, the first answer ente...

Abstract

Provided in the present application are a voiceprint recognition-based identity authentication method, the method comprising: collecting current voice data of a user, constructing a current voiceprint differentiation vector, and determining a corresponding standard voiceprint differentiation vector; calculating the distance between the current voiceprint differentiation vector and the standard voiceprint differentiation vector, and analyzing whether voiceprint authentication is successful; when the voiceprint authentication is successful, acquiring a manual authentication result; when manual authentication fails, analyzing the identity of the user again, and generating an authentication analysis result; and when the authentication analysis is successful, determining that the identity authentication of the user is successful, or, when the authentication analysis fails, determining that the identity authentication of the user fails. Further provided in the present application are an identity authentication server and a computer-readable storage medium. According to the present application, whether the identity of a user passes authentication is determined comprehensively by combining a voiceprint recognition result and a secondary authentication result, thereby improving the accuracy of the identity authentication of a user.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an identity verification method based on voiceprint recognition, a server and a computer-readable storage medium. Background technique [0002] At present, with the continuous development of voiceprint recognition technology, the use of voiceprint verification technology to verify user identity has become an important authentication method for major customer service companies (such as banks, insurance companies, game companies, etc.). [0003] The traditional user authentication scheme using voiceprint recognition technology is: if the voiceprint verification is passed, it is judged that the identity verification is passed; or, if the voiceprint verification is not passed, it is judged that the identity verification is not passed. [0004] However, the disadvantages of this traditional voiceprint verification scheme are: the accuracy of voiceprint verification is greatly affect...
