Referring to fig. 1, the voice password authentication method provided in the present application may be applied to an application environment shown in fig. 1. In which a terminal 110 communicates with a server 120 through a network, and a user 100 operates the terminal 110 through an input device. The terminal 110 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 120 may be implemented by an independent server or a server cluster formed by a plurality of servers.

In an embodiment, as shown in fig. 2, a voice password authentication method is provided, which is described by taking the method as an example applied to the terminal in fig. 1, but the method is not limited to be implemented only on the terminal, and specifically includes the following steps: s01, displaying verification prompt information

The prompt message may be a message that is verified in voice verification, such as a number less than ten, and a message that is also used to prompt the user to perform an operation, such as "please click on a displayed number".

In one embodiment, an online verification mode and an identification mode are verified; the terminal firstly identifies the identification mode of the current verification, and if the identification mode is a simple online verification mode, namely the verification purpose is only manual operation confirmation, a number within ten is displayed; if the identification is identification, prompting 'please tap the digital password in sequence' or 'please tap the digital password with the prompt' and the like.

S02, according to the verification password, the user taps to generate tapping sound and tapping rhythm

In the internet access verification mode, the user can knock the terminal on a screen, a back shell and the like according to the verification prompt information for a plurality of times to generate knocking sound. Of course, the operation is not limited to the terminal, and the sound can be generated by knocking other objects, such as a desk and the like.

In the identity recognition mode, a user can generate knocking sound on a screen, a back shell and the like of the terminal according to the verification prompt information by knocking times, and the knocking sound forms rhythm at intervals of numbers and certain time. For example: if the verification prompt message is 'please tap the second and third bits of the numeric password in sequence', if the second bit is '3' and the third bit is '1', the user only needs to tap 3 continuously, then tap 1 after stopping, and then the operation can be completed.

S03, recording, obtaining the sound frequency of the knocking sound, and identifying the knocking number and the knocking rhythm

The terminal collects the knocking sound of the user to form a sound wave frequency spectrum. The collected sound wave frequency spectrum corresponds to every knocking, and a wave crest can appear in the sound wave frequency spectrum, so that the identification is simple, and the accuracy rate is high. In the identification process, only the number of the continuous wave peaks is identified, and the number which needs to be input by the user can be identified. In addition, for the input with more than two numbers, in the identification process, an interval time period threshold value between wave peaks is preset, and if the interval time period threshold value is exceeded, the input of another verification code number can be considered to be started. Therefore, the user does not need to speak in the open, the problem that the user is embarrassed in the public environment or the environment with other people nearby is solved, the user does not need to speak towards the mobile internet terminal suddenly, or the user is difficult to open particularly when the user is famous, and meanwhile the privacy is prevented from being revealed.

S04, converting the information into character information to be verified, and verifying to obtain verification result

And the terminal collects the knocking sound of the user to form a sound wave frequency spectrum, converts the sound wave frequency spectrum into character information to be verified, and verifies the character information. And in the online verification mode, if the verification is passed, the corresponding page is automatically skipped. If the authentication passes in the identification mode, the identity is confirmed, allowing the user to do further operations.

Referring to fig. 3, in one embodiment, further includes:

s00, collecting specimen of voice password

And the terminal starts a recording function, collects a sample of the voice password and forms an original sound wave frequency spectrum corresponding to the user. The user can customize the number of taps and the tempo change. For example: if the user is customized to a total of 10 taps, the tempo changes to: 1-3-3- -2-1, only corresponding times need to be knocked in sequence when the samples of the voice passwords are collected, and rhythms are formed according to corresponding intervals. Where each number represents the number of consecutive taps and "-" represents the time unit of the interval. Each user can customize the personalized number and rhythm of taps. Preferably, when the total number of taps is large, such as 15, more rhythm changes can be customized: "5-10", or "1-3-5-3- - -3", etc., each user may define himself. The terminal collects the knocking sound, extracts information such as wave crests, continuous times, wave crest interval time intervals and the like after forming a sound wave frequency spectrum, converts the information into character information representing the user password, such as 1-3-3-2-1, and the character information is locally cached or sent to a server to serve as an original password or a secret key of the user.

S01, displaying verification prompt information

If the user records the sample of the voice password, a prompt of 'please click the recorded voice password and rhythm' or a related approximate prompt is displayed.

In the internet access authentication mode or the identity recognition mode, a user only needs to knock on a screen, a back shell or a nearby object of the terminal according to a pre-recorded password and rhythm to generate knocking sound, the number of wave crests of the knocking sound is the same as that of the original recording, and the change trend of the rhythm and the original recording is the same.

The terminal collects the knocking sound of the user to form a sound wave frequency spectrum.

The terminal collects a sound wave frequency spectrum formed according to the collected knocking sound of the user, extracts information such as wave crests, the times of continuous wave crests and interval time periods among discontinuous wave crests, converts the information into character information of a password to be verified, and verifies the character information. For example, if the voice command stored by the user at the server is "1-3-3-2-1", the voice command is converted into the character information to be verified, which is also "1-3-3-2-1", and the verification is passed. In an optimization, the verification process can set fault-tolerant rules, such as completely identical knocking times and differences of local rhythms, for example, "1-3-3-2-1"; local identity exceeding a threshold, such as "1-3-3-2", "3-3-2-1", etc., may be considered to be the same instruction, thus increasing the validation pass rate. The specific implementation can be customized and configured according to the actual situation.

In one embodiment, S03, recording, obtaining the audio of the tapping sound, identifying the number of taps and the tapping rhythm, and detecting the vibration of the terminal to acquire the vibration variation curve. The terminal not only generates tapping sound but also inevitably generates vibration by tapping at each time, a vibration curve is formed by detecting the vibration caused by each tapping, and the vibration curve is converted into second character information to be verified according to the wave crest of the curve, the quantity of the wave crest and the time interval of the wave crest, so that the accuracy rate of voice password verification can be improved. When the environment is noisy or the voice acquisition fails, the vibration detection can be used as an auxiliary verification means so as to improve the identification accuracy and expand the application occasions. The vibration detection and conversion into the character information to be verified is similar to the processing of the knocking sound, and the processing is not repeated. Therefore, when the verification is carried out through the voice password verification method, a user only needs to knock a terminal screen, a back shell or peripheral objects to generate knocking sound, and the user can carry out verification by knocking the body with a preset rhythm, so that the problem that the user is difficult to open in public places and the like is effectively solved, the operation is convenient, and brand-new use experience can be brought to the user.

In one embodiment, as shown in fig. 4, there is provided an authentication apparatus including: verification information prompt module, audio acquisition module, audio identification module, verification information conversion module, comparison module, wherein: and the verification information prompt module is used for prompting voice password verification operation. The audio acquisition module is used for starting a recording function, acquiring a sample of the voice password, forming an original sound wave spectrum corresponding to the user and further completing the sample acquisition of the voice password; and collecting the knocking sound of the user to form a sound wave frequency spectrum. The audio identification module is used for extracting information such as wave crests, continuous wave crest times, interval time periods between discontinuous wave crests and the like according to the collected sound wave frequency spectrum. And the verification information conversion module is used for converting the information identified by the audio identification module into character information of the password to be verified. The comparison module is used for comparing the pre-recorded or preset password for verification.
