Identity authentication protocol and server based on dynamic code and dynamic voice print updating

Abstract

The invention provides an identity authentication protocol and server based on a dynamic code and dynamic voice print updating. The identity authentication protocol comprises the following steps: receiving an identity authentication request sent by a client; randomly generating a dynamic password with a preset number of bits, and generating a password acoustic model according to the dynamic password with the preset number of bits; sending the dynamic password with the preset number of bits to the client; receiving an authentication audio file sent by the client; performing speech recognition on the authentication audio file to confirm voice contents in the authentication audio file; extracting first voice print in the authentication audio file; and determining that the voice contents in the authentication audio file; are the same as the dynamic password with the preset number of bits by using the password acoustic model, and determining that a matching value of the first voice print and a preset registration voice print is higher than a preset matching threshold, sending identity authentication success information to the client. By adoption of the identity authentication protocol provided by the invention, the technical problems that the verification code and the password input verification mode in the existing verification mode has a large theft risk and that the fingerprint verification mode has a high verification failure rate are solved.

Description

technical field [0001] The invention relates to the technical field of voiceprint recognition, in particular to an identity authentication protocol and server based on dynamic code and dynamic voiceprint update. Background technique [0002] With the promotion of mobile payment, more and more people like to use e-bank or e-wallet for mobile payment. [0003] Existing technologies usually use a single verification method for risky operations such as payment, such as verification codes, fingerprints, or traditional password input verification methods. Among them, verification codes and password input verification methods have a high risk of being stolen, while fingerprint verification methods exist. Technical issues with a high verification failure rate. Contents of the invention [0004] The invention provides an identity authentication protocol and server based on a dynamic code and a dynamic voiceprint update, which solves the problem that the verification code and passw...
