The best mode of the present invention

In order to make the purpose, technical solutions, and advantages of this application clearer and clearer, the following further describes the application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

The voiceprint data processing method provided in this application can be applied to the application environment as shown in FIG. 1. Fig. 1 is a diagram of an application environment in which a voiceprint data processing method operates in an embodiment. As shown in FIG. 1, the application environment includes a terminal 110 and a server 120. The terminal and the server communicate through the network. The communication network may be a wireless or wired communication network, such as an IP network, a cellular mobile communication network, etc., where the number of terminals and servers is not limited.

Among them, the terminal 110 may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices. The server can be implemented as an independent server or a server cluster composed of multiple servers. The terminal 110 obtains the first voiceprint collected by the first application, and obtains the valid device identification information corresponding to the first application locally. The valid device identification information is based on the device universally unique identification information of the device where the first application is located and the application information of the first application The generated universal unique identification information of the device includes one of the device serial number or the mobile device identification code, and the voiceprint verification request is sent to the server 120. The voiceprint verification request includes the valid device identification information and the first voiceprint, so that the server Obtain the standard voiceprint corresponding to the first application according to the valid device identification information, verify the consistency of the standard voiceprint and the first voiceprint to obtain a verification result; receive the verification result returned by the server 120, and perform corresponding operations according to the verification result.

In an embodiment, as shown in FIG. 2, a method for processing voiceprint data is provided. Taking the method applied to the terminal 110 in FIG. 1 as an example for description, the method includes the following steps:

Step 210: Obtain a first voiceprint collected by a first application, and obtain valid device identification information corresponding to the first application locally, where the valid device identification information is based on the universally unique identification information of the device where the first application is located Generated with the application information of the first application, the universal unique identification information of the device includes one of a device serial number or a mobile device identification code.

Among them, the first application may be an application that comes with the system on the device, or may be an application installed by downloading. The type of the first application is not limited, and may be a login application, a payment application, a social application, a game application, and so on. The first application may be one or more sub-applications in the main application, and each sub-application is attached to the main application to run and enter the sub-application through the main application's page.

Specifically, the valid device identification information corresponding to each application can be obtained from the storage space corresponding to each application. This storage space still exists after the application is uninstalled. If it is installed again after uninstallation, the application data of this application previously stored in this storage space It can still be used. The data in the target storage space can be stored in the form of key-value pairs. In one embodiment, the key is a unique name for editing, for example: key=voice:print:username, and the value is the valid device identification information corresponding to the application.

Voiceprint refers to the sound wave spectrum of a voice signal. Voiceprint has specificity and stability. Through voiceprint recognition, user identity can be detected. The collected voice data can be extracted through the voiceprint feature extraction model to obtain the voiceprint feature, so as to obtain the first voiceprint according to the voiceprint feature. Voiceprint features can include: acoustic features, morphological features, prosodic features, language, dialect and accent information, channel information, etc.

The serial number of the device is the unique serial number given by the device. Some devices will return junk data. Therefore, when the normal serial number cannot be returned on the device, the mobile device identification code will be used. The mobile device identification code includes IMEI ( International Mobile Equipment Identity, international mobile equipment identification code) number, by GSM (Global System for Mobile Communications (Global System for Mobile Communications) device returns, reinstallation of the application will not change, the user must grant permission. The MEID (Mobile Equipment Identifier)/ESN (Electronic Serial Number) number is returned by the CDMA (Code Division Multiple Access) device. Usually the device supports both GSM and CDMA, the IMEI number And MEID/ESN number can participate in generating effective equipment identification information at the same time. When the junk data is returned after extracting the serial number, the application will apply to the user for the "read_phone_state" permission to open the device. After having this permission, the IMEI number and MEID/ESN number of the device can be extracted.

The device's universal unique identification information is generated by the device's own system. The device's universal unique identification code can ensure that all elements in the distributed system have unique identification information, but there may be two identical device universal unique identification information. The value of the valid device identification information is unique, because the valid device identification information is generated by the universal unique identification information of the device and the application information of the first application to further ensure uniqueness. The application information of the first application is information unique to the application, and may be application identification information, application operation information, etc., or a combination of multiple different types of application information.

In one embodiment, the valid device identification information includes identification bit information, and the identification bit information is used to identify the information category of the universally unique identification information of the device.

In an embodiment, valid device identification information is also generated according to historical operation information acting on the first application. The historical operation information includes at least one of time operation information, space operation information, and equipment space status. Time operation information includes current operation time, system time can be converted to Timestamp, spatial operation information includes geographic location information, and geographic location information can be converted to region through "World and Region Name Code" and "National Region Code Table" Code Location. The space state of the device can be the current space position of the device, including the tilt angle, and the movement speed can be collected by the gyroscope. The historical operation information may also include operation object information, such as the user ID of the operation application. Multiple different types of historical operation information and device universal unique identification codes can be combined to generate valid device identification information.

Even if different applications belong to the same device, different applications have different unique valid device identification information due to different application information.

Step 220: Send a voiceprint verification request to the server. The voiceprint verification request includes valid device identification information and the first voiceprint, so that the server obtains the standard voiceprint corresponding to the first application according to the valid device identification information, and verifies the standard voiceprint The consistency with the first voiceprint is verified.

Specifically, the voiceprint verification request is used to verify whether the currently collected voiceprint is consistent with the historically bound voiceprint. If they are consistent, it means that the user's identity has been verified and the corresponding operation can be performed on the first application. If the verification fails, it means that the user identity verification has failed, and there is no operating authority for the first application. In order to obtain the standard voiceprint corresponding to this application of this device, it is necessary to send the valid device identification information corresponding to this application of this device to the server to obtain the corresponding standard voiceprint. Since the valid device identification information is unique, the corresponding standard voiceprint can be uniquely determined, effectively avoiding the problem of incorrect standard voiceprint obtained by the same device identification information in different applications of multiple different devices, resulting in inaccurate verification results , And because of the uniqueness of the effective device identification information, the server only needs to store the association relationship between the effective device identification information and the standard voiceprint, so that different devices can be distinguished, and the same applications on different devices can also be distinguished. Different applications on the device can also be distinguished, which improves the accuracy of voiceprint verification and ensures the effectiveness of voiceprint information management.

Step 230: Receive the verification result returned by the server, and perform a corresponding operation according to the verification result.

Specifically, if the verification is successful, the corresponding operation can be performed on the first application. When you need to operate different functions on different pages of the application, you can send one or more voiceprint verification requests to the server at a time. If the same voiceprint is used for verification of multiple different application operation instructions, the voiceprint verification request only needs to be Including the same collected voiceprint, if different voiceprints are used for verification of different application operation instructions, the voiceprint verification request can include multiple first voiceprints, corresponding to each application operation instruction, and multiple application operation instructions are obtained Corresponding to different verification results, only the operation whose verification result is a verified operation instruction can be executed. In this case, it is necessary to ensure that there is a corresponding standard voiceprint for each different operation command of the same device.

In this embodiment, the valid device identification information corresponding to the first application is obtained locally. The valid device identification information is generated by the device universally unique identification information of the device where the first application is located and the application information of the first application, and the server is generated according to the valid device identification information Obtain the corresponding standard voiceprint, because the effective device identification information is unique for different devices and different applications, thus ensuring the accuracy of obtaining the standard voiceprint on different devices, and verifying the consistency of the standard voiceprint and the first voiceprint The verification result is obtained, thereby improving the accuracy of the voiceprint verification and ensuring the accuracy of the operation authority for performing the corresponding operation according to the voiceprint verification result.

In one embodiment, the method further includes: obtaining an operation instruction acting on the first application; collecting the standard voiceprint corresponding to the first application through the first application; obtaining the universally unique identification information of the device where the first application is located, according to the device The universally unique identification information and the application information of the first application generate the current device identification information corresponding to the first application; when there is no valid device identification information corresponding to the first application locally, the current device identification information is used as the valid device corresponding to the first application The identification information is stored locally, and the valid device identification information and the standard voiceprint are sent to the server, so that the server stores the association relationship between the effective device identification information and the standard voiceprint.

The operation instruction is used to perform a corresponding operation on the first application, and may be an installation operation instruction, a startup operation instruction, a login operation instruction, an add friend operation instruction, a payment operation instruction, and the like. It is understandable that there can be one or more operation instructions, but as long as valid device identification information already exists locally, there is no need to regenerate the current device identification information for subsequent acquisitions of the operation instructions. The same device has the same application. Various operations that require voiceprint verification share the same standard voiceprint.

Specifically, the standard voiceprint may be the voiceprint of the user of the device owner, and only users who match the standard voiceprint have the authority to operate applications on the device. Since the effective device identification information generated by different applications of the same device is different, different standard voiceprints can be set for different applications. The generated valid device identification information corresponding to each application is stored in the local private storage space corresponding to each application, so as to ensure the convenience and accuracy of subsequent acquisition of the valid device identification information corresponding to each application. The association between the device identification information and the standard voiceprint facilitates subsequent voiceprint verification.

In one embodiment, when the server stores the voiceprint of the device user, it sets a flag bit for the effective device identification information. If the flag position is "1", it means that the serial number is used when generating the effective device identification information for the device. SerialNumber; if the flag position is "0", it means that the device used the IMEI number or MEID/ESN number when generating valid device identification information.

In one embodiment, the operation instruction acting on the first application is acquired, the standard voiceprint corresponding to the first application is collected through the first application, and the universal unique identifier of the device where the first application is located is acquired Information, generating the current device identification information corresponding to the first application according to the universally unique identification information of the device and the application information of the first application includes: acquiring an application startup instruction for starting the first application for the first time; acquiring the first application according to the application startup instruction 1. The device serial number of the device where the application is located. When the device serial number is normal data, the device serial number and the application information of the first application are combined to generate the current device identification information corresponding to the first application; when the device serial number is abnormal data, The mobile device identification code of the device where the first application is located is obtained, and the mobile device identification code and the application information of the first application are combined to generate current device identification information corresponding to the first application.

Specifically, the device serial number SerialNumber can be obtained through the "android.os.Build.SERIAL" code that comes with the system. Since this interface does not distinguish whether the device is a mobile phone or a tablet or other types of devices, the application can read the device The serial number serves as the main identification of the device. However, using this method on some mobile phones will return junk data and cannot identify the device. At this time, you can use the IMEI number and MEID/ESN number for assistance. These three identifications can meet the requirements of GSM equipment and CDMA equipment at the same time. The device model is not supported and the acquisition fails. So when the junk data is returned after extracting the serial number, the application will apply to the user for the "read_phone_state" permission to open the device. With this permission, the mobile device identification code of the device, namely the IMEI number and/or MEID/ESN number can be extracted.

In one embodiment, when the device serial number is used, the identification bit information of the current device identification information is set to the first value; when the mobile device identification code is used, the identification bit information of the current device identification information is set to the second value. If the device serial number is used, the identification information can be set to 1, and if the mobile device identification code is used, the identification information can be set to 0.

In one embodiment, the current device identification information is stored locally as the valid device identification information corresponding to the first application: a random prefix and a random suffix are generated, and the random prefix, current device identification information, and random suffix are combined in order to generate processing Device identification information. The processing device identification information is encrypted to obtain the encrypted device identification information, and the encrypted device identification information is stored locally as valid device identification information corresponding to the first application.

Specifically, the current device identification information generated by the above method reduces the recognizability of the identification through combination, but the encryption of the current device identification information is also extremely important. Use the method of generating random numbers to add a random prefix and a random suffix to the current device identification information to obtain the processing device identification information, and then adopt an encryption algorithm, such as base62 to encode the encrypted device identification information, which can greatly increase the security of the identification code and ensure that it will not be easily Cracked by the attacker. In one embodiment, when the first application is started for the first time, the identification code generated by the combined encryption is stored locally as the unique identification of the device corresponding to the first application, and the value is transmitted back to the server and the standard at the same time. Voiceprint is stored. When you want to match the device identification later, you only need to check whether there is a stored value in the space corresponding to the first application in the device's local area. If it has been stored, the value is directly taken out for matching work, and the corresponding standard voiceprint is obtained. If there is no storage, it means a match. Fail and store the value generated this time.

In one embodiment, the method further includes: obtaining the current operation instruction type, and when the current operation instruction type does not have corresponding valid device identification information locally, generating the current operation instruction according to the current operation instruction type and the current device identification information The effective device identification information corresponding to the type of operation is stored locally, and the effective device identification information and standard voiceprint corresponding to the current operation instruction type are sent to the server so that the server stores the effective device identification information and standard voice corresponding to the current operation instruction type. The relationship between patterns. Obtain the first operation instruction acting on the first application, determine the first operation instruction type corresponding to the first operation instruction; obtain the target valid device identification information corresponding to the first operation instruction type; the voiceprint verification request includes the target valid device identification information, The first voiceprint, so that the server obtains the target standard voiceprint matching the first operation instruction type according to the target effective device identification information, and verifies the consistency of the target standard voiceprint with the first voiceprint to obtain the verification result corresponding to the first operation instruction .

Specifically, according to the function of the operation instruction, the operation instruction of the same function can be regarded as the same type of operation instruction, such as payment type operation instruction, login type operation instruction, and friend type operation instruction. Different types of operation instructions have different levels of priority. Level and security can be verified by the voiceprints of users with different levels of identity. If the payment type requires a higher level of priority, it will be verified by the voiceprint of the user with a higher level of identity. According to the current operation instruction type and the current device identification information, the effective device identification information corresponding to the current operation instruction type is generated, so that according to different operation instruction types, the corresponding different effective device identification information can be obtained. Different types of operation instructions of the same application correspond to different Valid device identification information, so that the standard voiceprint corresponding to the target operation instruction type of the target application can be obtained from the server through the effective device identification information, so that different types of operation instructions of the same application have different standard voiceprints, which can be verified by different user identities . Due to the uniqueness of the effective device identification information generation, the accuracy of the standard voiceprint acquisition is guaranteed.

In one embodiment, the verification result includes verification results corresponding to a plurality of different operation instructions, and step 230 includes: obtaining the operation instruction whose verification result is passed as the target execution operation instruction, and execute the operation instruction that acts on the first application according to each target. The target operation, the target operation includes at least one of a login operation, a payment operation, and an information modification operation.

Specifically, because different types of instructions can be verified by users with different identities, they may also correspond to different verification results. Only the operation instructions that pass the verification result can execute the corresponding operation, and multiple operation instructions can be verified in parallel at one time The operation authority of the operation authority is verified in parallel by the voiceprint verification request carrying the voiceprint corresponding to the operation instruction, which improves the efficiency of voiceprint verification and the convenience of authority distribution.
