Embodiment 1

[0052] figure 1 This is a flowchart of a voiceprint verification method provided in Embodiment 1 of the present invention. This embodiment is applicable to a user registration system such as passport and other similar user quick 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 a random identifier of each keyboard element with a fixed identifier, so that the user can set a password by inputting a sound signal of the random identifier of at least one 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 6This is a flowchart of a voiceprint verification method provided in Embodiment 3 of the present invention. This embodiment is applicable to a user login system 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 a random identifier of each keyboard element with a fixed identifier, so that the user can input a password by inputting a sound signal of the random identifier of at least one keyboard element when logging in;

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

Abstract

The invention discloses a voiceprint authentication method and device. The method includes the steps that a client generates and displays random identifiers of all keyboard elements with fixed identifiers, so that a user can set a password by inputting voice signals of the random identifiers of at least one keyboard element; the client receives first voice signals input by the user when setting the password and transmits the first voice signals to a server; the server receives the first voice signals sent by the client and input when the user sets the password; the server extracts at least one random identifier from the first voice signals, and all random identifiers correspond to the keyboard elements with the fixed identifiers respectively; the server determines the fixed identifiers of the keyboard elements corresponding to all the extracted random identifiers respectively, and determines and stores the password set by the user according to the determined fixed identifiers. By means of the method, the problem that in the prior art, the fixed password is visible is solved, and safety 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] The traditional login method based on password or gesture is generally safe. Once the password or gesture is known to others, the login can also be completed. Voiceprint verification uses the user's voiceprint information to enhance security. In the prior art, a voiceprint recognition method is used to authenticate the logged-in user, which mainly includes a voiceprint authentication method combining a random number string / arbitrary text and a keyboard password. [0003] The details are as follows: in the user registration stage, 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. The signal is transmitted to the server,...
