Problems solved by technology

[0002] Since everyone speaks with a relatively stable frequency spectrum, the characteristics of these frequency spectrums are voiceprints. At present, voiceprint authentication has mature applications, such as the reserved voice samples "voice 1, 2, 3, 4, 5, 6" in WeChat The method of authentication, but there is a shortcoming in this authentication method, because human speech is a relatively stable frequency spectrum, and the reserved voice samples may be early, as time changes, sometimes the authentication fails due to changes in the vocal cords

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] figure 1 It is a flow chart of the present invention, including a mobile phone terminal and a server. Normal communication is carried out after instant messaging logs in to the server successfully, and the server records the language files to form a language file database and a call log. The steps of the present invention are:

[0025] 101 instant messaging login request;

[0026] 102 Extract the recent language file A in the call log;

[0027] 103. Identify and convert the language file A into text, and push the text to the client;

[0028] 104 Record the language of the pushed text, and the instant messaging user records the language of the pushed text according to the pushed text and imitates the scene of the original call;

[0029] 105 upload the language file B of the recorded push text;

[0030] 106 compare the voiceprints of language f...

Abstract

The invention relates to the information safety field, and especially relates to an immediate updating voiceprint authentication method and system. The immediate updating voiceprint authentication method is characterized by comprising the following steps: step (1), establishing a language file database containing a call log; step (2), acquiring a recent language file A in the call log; step (3), identifying the language file A and converting the language file A into words, and pushing the words to a client; step (4), recording languages of the pushed words by the client, and uploading a recorded language file B; and step (5), comparing a voiceprint of the language file B with a voiceprint of the language file A. The beneficial effects are as follows: the invention aims to provide the immediate updating voiceprint authentication method and the system, specifically for a WeChat application, voiceprint authentication can be carried out based on an original language call record, therefore, a sample language recording step can be omitted; and meanwhile, WeChat users generally have fresh memories of own recent language call tones, so that a foundation is laid for intonation authentication, and the authentication can be carried out by using joint comparison of voiceprints and intonations.

Description

technical field [0001] The invention relates to the field of information security, in particular to an instant-updated voiceprint authentication method and system. Background technique [0002] Since everyone speaks with a relatively stable frequency spectrum, the characteristics of these frequency spectrums are voiceprints. At present, voiceprint authentication has mature applications, such as the reserved voice samples "voice 1, 2, 3, 4, 5, 6" in WeChat However, there is a shortcoming in this authentication method. Since human speech is a relatively stable frequency spectrum, the reserved voice samples may be early. As time changes, sometimes the authentication fails due to changes in the vocal cords. Contents of the invention [0003] The purpose of the present invention is to provide an instant updated voiceprint authentication method and system. [0004] Technical scheme of the present invention is: [0005] An instant updated voiceprint authentication method, setti...
