Detailed Description
In order to make the objects, technical solutions and advantages of the present application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.
The voiceprint data processing method provided by the application can be applied to the application environment shown in fig. 1. FIG. 1 is a diagram of an application environment in which a voiceprint data processing method operates in one embodiment. As shown in fig. 1, the application environment includes a terminal 110 and a server 120. The terminals and the servers communicate with each other through a network, which may be a wireless or wired communication network, such as an IP network, a cellular mobile communication network, etc., wherein the number of the terminals and the servers is not limited.
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 may be implemented as a stand-alone server or as a server cluster consisting of a plurality of servers. The terminal 110 acquires a first voiceprint acquired by a first application, acquires a target storage space corresponding to the first application, acquires effective equipment identification information corresponding to the first application from the target storage space, wherein the effective equipment identification information is generated according to an equipment universal unique identification code of equipment where the first application is located and historical operation information of the first application, and sends a voiceprint verification request to the server 120, the voiceprint verification request comprises the effective equipment identification information and the first voiceprint, so that the server acquires a standard voiceprint corresponding to the first application according to the effective equipment identification information, and verifies the consistency of the standard voiceprint and the first voiceprint to obtain a verification result; and receiving the verification result returned by the server 120, and executing corresponding operation according to the verification result.
In one embodiment, as shown in fig. 2, a voiceprint data processing method is provided, which is described by taking the method as an example applied to the terminal 110 in fig. 1, and includes the following steps:
step 210, acquiring a first voiceprint acquired by the first application, acquiring a target storage space corresponding to the first application, and acquiring effective device identification information corresponding to the first application from the target storage space, wherein the effective device identification information is generated according to a device universal unique identification code of a device where the first application is located and historical operation information of the first application.
The first application may be an application carried by a system on the device, or an application installed by downloading, and 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 the like. The first application may be one or more sub-applications within the main application, each sub-application running dependent on the main application, entering the sub-application through a page of the main application.
Specifically, each application has a corresponding storage space, and this storage space still exists after the application is uninstalled, and if the application is installed again after uninstalling, the application data of this application stored before this storage space can still be used. The data in the target storage space may be stored in the form of key-value pairs. In one embodiment, a key is a unique name for an edit, such as: key = voice print name, value is valid device identification information corresponding to the application. In one embodiment, the data is stored through keyChain in the iOS operating system, the keyChain is a storage space, the data is stored in a "key-value" form, and four operations of adding, deleting, changing and searching can be performed on the data.
The voiceprint is a sound wave frequency spectrum of a voice signal, has specificity and stability, and can be used for detecting the identity of a user through voiceprint recognition. The collected voice data can be extracted through a voiceprint feature extraction model to obtain voiceprint features, and therefore the first voiceprint is obtained according to the voiceprint features. The voiceprint features can include: acoustic features, lexical features, prosodic features, languages, dialect and accent information, channel information, and the like.
The universal unique identification code of the equipment is generated by a system of the equipment when calling the application every time, for example, the UUID generated by the ios system, and the system does not store the UUID, so that the UUID is stored by a target storage space corresponding to the application. The device common unique identification code may guarantee that all elements in the distributed system have unique identification information, but there may be 2 identical device common unique identification codes. The value of the valid device identification information is unique, and the uniqueness is further ensured because the valid device identification information is generated by the device universal unique identification code and the historical operation information of the first application. The historical operation information comprises at least one of time operation information, space operation information and equipment space state. The time operation information includes a current operation time, and may convert a system time into a Timestamp, and the space operation information includes geographical Location information, and may convert the geographical Location information into a region code Location through a "world and region name code" and a "national region code table". The space state of the device can be the current space position of the device, including the inclination angle, and the movement speed can be acquired through a gyroscope. The historical operation information may also include operation object information, such as application identification, user identification of the operating application, and the like. A variety of different types of historical operating information and device universal unique identification codes may be combined to generate valid device identification information.
Even if different applications belong to the same device, different unique valid device identification information exists due to different historical operation information and different generation time of the universal unique identification code of the device.
Step 220, sending a voiceprint verification request to the server, where the voiceprint verification request includes the valid device identification information and the first voiceprint, so that the server obtains a standard voiceprint corresponding to the first application according to the valid device identification information, and verifying the consistency of the standard voiceprint and the first voiceprint to obtain a verification result.
Specifically, the voiceprint verification request is used for verifying whether the currently acquired voiceprint is consistent with the voiceprint bound in the history, if so, the user identity is verified, and corresponding operation can be executed on the first application. If the authentication is not passed, the authentication of the user is failed, and the operation authority of the first application does not exist. In order to obtain the standard voiceprint corresponding to the application of the device, the valid device identification information corresponding to the application of the device needs to be sent to the server to obtain the corresponding standard voiceprint. The effective equipment identification information is unique, so that the corresponding standard voiceprint can be uniquely determined, the problem that the verification result is inaccurate due to the fact that the same equipment identification information is obtained from different applications of a plurality of different equipment to obtain the wrong standard voiceprint is effectively solved, and due to the uniqueness of the effective equipment identification information, the server can distinguish different equipment, can distinguish the same application on different equipment and can distinguish different applications on the same equipment only by storing the incidence relation between the effective equipment identification information and the standard voiceprint, so that the voiceprint verification accuracy is improved, and the voiceprint information management effectiveness is guaranteed.
And step 230, receiving the verification result returned by the server, and executing corresponding operation according to the verification result.
Specifically, if the verification is successful, the corresponding operation may be performed on the first application. When different functions of different pages of the application need to be operated, one or more voiceprint verification requests can be sent to the server at one time, if the same voiceprint is adopted when a plurality of different application operating instructions are verified, the voiceprint verification requests only need to comprise the same collected voiceprint, if different voiceprints are adopted when different application operating instructions are verified, the voiceprint verification requests can comprise a plurality of first voiceprints and correspond to the application operating instructions, a plurality of different verification results corresponding to the application operating instructions are obtained, and only the verification results can be executed for the operation of the operating instructions passing the verification. In this case, it is necessary to ensure that each different operation command of the same device has a corresponding standard voiceprint.
In this embodiment, effective device identification information corresponding to a first application is acquired from a target storage space, the effective device identification information is generated by a device-universal unique identification code of a device where the first application is located and historical operation information for the first application, and a corresponding standard voiceprint is acquired from a server according to the effective device identification information.
In one embodiment, the method further comprises: the method comprises the steps of obtaining an operation instruction acting on a first application, obtaining current operation information corresponding to the operation instruction, collecting a standard voiceprint corresponding to the first application through the first application, obtaining a device universal unique identification code of a device where the first application is located, generating current device identification information corresponding to the first application according to the device universal unique identification code and the current operation information, obtaining a target storage space corresponding to the first application, storing the current device identification information serving as effective device identification information to the target storage space when the effective device identification information corresponding to the first application does not exist in the target storage space, and sending the effective device identification information and the standard voiceprint to a server so that the server stores the incidence relation between the effective device identification information and the standard voiceprint.
The operation instruction is used for executing corresponding operation on the first application, and may be an installation operation instruction, a start operation instruction, a login operation instruction, a friend adding operation instruction, a payment operation instruction and the like. It can be understood that the operation instruction may be one or more, but as long as the target storage space already has valid device identification information, the subsequent operation instruction does not need to be obtained again, and the current device identification information does not need to be generated again, and various operations of the same device and the same application, which need to verify the voiceprint, share the same standard voiceprint.
In particular, the standard voiceprint can be a voiceprint of a user of the device owner, only users matching the standard voiceprint having permission to operate an application on the device. Since the valid device identification information generated by different applications of the same device is different, different standard voiceprints can be set for different applications. The generated effective equipment identification information corresponding to each application is stored in the private storage space corresponding to each application, so that the convenience and accuracy of subsequent acquisition of the effective equipment identification information corresponding to each application are ensured, and the incidence relation between the effective equipment identification information and the standard voiceprint is prestored in the server, so that subsequent voiceprint verification is facilitated.
In one embodiment, the obtaining of an operation instruction acting on a first application, obtaining current operation information corresponding to the operation instruction, acquiring a standard voiceprint corresponding to the first application through the first application, obtaining a device universal unique identification code of a device where the first application is located, and generating current device identification information corresponding to the first application according to the device universal unique identification code and the current operation information includes: acquiring an application starting instruction for starting a first application for the first time; acquiring the system time of current equipment corresponding to an application starting instruction, acquiring the geographical position information of the current equipment corresponding to the application starting instruction, and acquiring a universal unique identification code of the equipment generated by the equipment where the first application is located according to the system time of the current equipment; and combining the current equipment system time, the current equipment geographic position information and the equipment universal unique identification code to generate current equipment identification information corresponding to the first application.
Specifically, the first application, which is used as the application of the current voiceprint recognition, simultaneously obtains the device universal unique identifier UUID generated by the system and the system time and the located geographic Location of the device when the current device is started for the first time, may convert the system time into a Timestamp, and converts the geographic Location into a region code Location through a "world country and region name code" and a "national region code table". Finally, the character string generated by combining the UUID, the Timestamp and the Location is used as the current equipment identification information of the equipment, and the application is started on the equipment without regeneration.
In one embodiment, storing the current device identification information as valid device identification information to the target storage space comprises: and generating a random prefix and a random suffix, and combining the random prefix, the current equipment identification information and the random suffix in sequence to generate processing equipment identification information. And encrypting the processing equipment identification information to obtain encrypted equipment identification information, and storing the encrypted equipment identification information to a target storage space.
Specifically, the current device identification information generated by the above method is combined to reduce the identifiability of the identification, but the encryption of the current device identification information is also very important. The method for generating the random numbers is used for adding the random prefix and the random suffix to the current equipment identification information to obtain the processing equipment identification information, and then an encryption algorithm is adopted, such as base62, for coding to obtain the encryption equipment identification information, so that the safety of the identification code can be greatly improved, and the identification code cannot be easily cracked by attackers. In one embodiment, when the first application is started for the first time, the identification code generated by combined encryption is stored in the keyChain to serve as the unique identification of the device corresponding to the first application, and the value is transmitted back to the server side to be stored with the standard voiceprint. And then, when the equipment identification is matched, only checking whether a storage numerical value exists in keyChain of the equipment, if so, directly taking out the value to perform matching work, acquiring a corresponding standard voiceprint, and if not, representing that the matching fails and storing the generated value.
In one embodiment, step 210 is preceded by: the method comprises the steps of obtaining a current operation instruction type, storing data in a target storage space in a key-value pair mode, wherein a key is the current operation instruction type, a value is effective equipment identification information, and when the current operation instruction type does not have corresponding effective equipment identification information in the target storage space, storing the current operation instruction type and the current equipment identification information in the target storage space in the key-value pair mode. And acquiring a target standard voiceprint corresponding to the current operation instruction type, and sending the effective equipment identification information and the target standard voiceprint to the server so that the server stores the association relationship between the effective equipment identification information and the target standard voiceprint. The method further comprises the following steps: acquiring a first operation instruction acting on a first application, and determining a first operation instruction type corresponding to the first operation instruction; and acquiring effective equipment identification information which is corresponding to the first application and is matched with the first operation instruction type from the target storage space. The voiceprint verification request comprises effective equipment identification information and a first voiceprint, so that the server obtains a target standard voiceprint matched with the type of the first operation instruction according to the effective equipment identification information, and a verification result corresponding to the first operation instruction is obtained by verifying the consistency of the target standard voiceprint and the first voiceprint.
Specifically, according to the function of the operation instruction, the operation instruction with the same function may be used as the operation instruction with the same type, such as a payment type operation instruction, a login type operation instruction, and a friend adding type operation instruction, where the operation instructions with different types have different levels of priority and security, and may be verified by voiceprints of users with different levels of identities. If the payment type requires a higher level of priority, then authentication is performed by the voiceprint of the user with the higher level of identity. The current operation instruction type and the current equipment identification information are stored in a target storage space in a key value pair mode, so that corresponding different effective equipment identification information can be obtained according to different operation instruction types, operation instructions of the same application different types correspond to different effective equipment identification information, and a standard voiceprint corresponding to the target application operation instruction type can be obtained from a server through the effective equipment identification information, so that the operation instructions of the same application different types have different standard voiceprints, and verification is performed through different user identities. Due to the uniqueness of the effective equipment identification information generation, the accuracy of the standard voiceprint acquisition is ensured.
In one embodiment, the verification result includes verification results corresponding to a plurality of different operation instructions, and step 230 includes: and obtaining the operation instruction with the verification result of passing as a target execution operation instruction, and executing target operation acting on the first application according to each target execution operation instruction, wherein the target operation comprises at least one of login operation, payment operation and information modification operation.
Specifically, different types of instructions can be verified by users with different identities, so that the instructions can also correspond to different verification results, corresponding operations can be executed only if the verification results are the passed operation instructions, the operation authorities of a plurality of operation instructions can be verified in parallel at one time, and the voiceprint verification request carrying the voiceprint corresponding to the operation instructions is used for performing parallel verification, so that the voiceprint verification efficiency and the authority distribution convenience are improved.
