Embodiment 1

[0052] figure 1 It is a flow chart of a voiceprint verification method provided by Embodiment 1 of the present invention. This embodiment is applicable to user registration systems such as passport and other similar rapid user registration systems. The method is executed by the user client, and the method in this embodiment specifically includes the following operations:

[0053] 110. The client generates and displays the random identifier of each keyboard element with a fixed identifier, so that the user can set a password by inputting a sound signal of at least one random identifier of the keyboard element;

[0054]The fixed identifiers of the keyboard elements are letters or numbers or item pictures, and the random identifiers of the keyboard elements are letters or numbers. The client generates random identifiers of keyboard elements with fixed identifiers according to a certain algorithm, so that the fixed identifiers of each keyboard element correspond to a random ident...

Embodiment 2

[0067] Figure 5 It is a flow chart of a voiceprint verification method provided by Embodiment 2 of the present invention, the method is executed by the server, such as Figure 5 As shown, the method includes the following steps:

[0068] 210. The server receives the first sound signal sent by the client and input by the user when setting the password;

[0069] The first sound signal sent by the client when the user sets the password means that when the user registers, the client generates and displays the random identifier of each keyboard element with a fixed identifier and the password preset by itself, and enters Sound signal of random identifier of at least one keyboard element.

[0070] 220. The server extracts at least one random identifier from the first sound signal, where each random identifier corresponds to a keyboard element with a fixed identifier;

[0071] The fixed identifiers of the keyboard elements are letters or numbers or item pictures, and the random i...

Embodiment 3

[0088] Image 6It is a flow chart of a voiceprint verification method provided by Embodiment 3 of the present invention. This embodiment is applicable to user login systems such as passport and other similar user quick login systems. The method is executed by the user client, and the method in this embodiment specifically includes the following operations:

[0089] 310. The client generates and displays the random identifier of each keyboard element with a fixed identifier, so that the user inputs the password by inputting a sound signal of at least one random identifier of the keyboard element when logging in;

[0090] The fixed identifiers of the keyboard elements are letters or numbers or item pictures, and the random identifiers of the keyboard elements are letters or numbers. The client generates random identifiers of keyboard elements with fixed identifiers according to a certain algorithm, so that the fixed identifiers of each keyboard element correspond to a random id...

Abstract

The invention discloses a voiceprint verification method and device. The method includes: the client generates and displays the random identifier of each keyboard element with a fixed identifier, so that the user can input at least one random identifier of the keyboard element. The password is set by sound signal; the client receives the first sound signal input by the user when setting the password, and transmits the first sound signal to the server. The server receives the first sound signal sent by the client when the user enters the password; the server extracts at least one random identifier from the first sound signal, wherein each random identifier corresponds to a keyboard with a fixed identifier elements; the server determines the fixed identifiers of the keyboard elements corresponding to the extracted random identifiers, and determines and saves the password set by the user according to the determined fixed identifiers. Through the above method, the problem that the fixed password is visible in the prior art is avoided, and the security is improved.

Description

technical field [0001] Embodiments of the present invention relate to voiceprint recognition technology, and in particular to a voiceprint verification method and device. Background technique [0002] Traditional login methods based on passwords or gestures are of average security. Once the passwords or gestures are known to others, the login can also be completed. Voiceprint verification uses the user's voiceprint information to enhance security. In the prior art, the voiceprint recognition method is used to authenticate the login user, which mainly includes a voiceprint authentication method combining random number strings / arbitrary text and keyboard passwords. [0003] The details are as follows: During the user registration phase, the client receives the first sound signal generated by the user reading the password and the second sound signal generated by the user reading the random number string / arbitrary text generated by the server, and the client receives each sound...
