Detailed Description
Various exemplary embodiments, features and aspects of the present disclosure will be described in detail below with reference to the accompanying drawings. In addition, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present invention. It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details. In some instances, well known means have not been described in detail so as not to obscure the present invention.
Referring to fig. 1, an embodiment of the present invention provides a method for noninductive logging in a car machine account, including the following steps S1 to S5:
step S1, when the vehicle-mounted APP receives account information of a user for selecting login currently, the vehicle-mounted APP outputs first prompt information for prompting the user to send a preset voice instruction, and sends an account verification request to a voice assistant;
specifically, the car APP (Application program for short) is installed on the car, and the voice assistant may be integrated as a part of the car, for example.
The preset voice instruction can be a login account and is used for indicating to log in the vehicle-mounted computer account according to the account information selected by the user to log in currently.
When the step is implemented, the user inputs selection information through the input unit, and selects an account to be logged in, for example, account 1, it should be noted that account 1 should be an account that has been previously subjected to voiceprint registration, otherwise, the subsequent step S3 will fail, and the vehicle account cannot be logged in without sense. The following description of the embodiments will be given by taking account 1 as an example.
In the step, when the vehicle APP receives account information selected by a user to log in, the first prompt information is generated, displayed through a display unit of the vehicle APP and/or broadcasted through a voice broadcasting unit of the vehicle APP, and meanwhile, an account verification request is generated and sent to a voice assistant.
Step S2, the voice assistant responds to the account verification request, acquires a current voice instruction sent by the user, and performs voice recognition on the current voice instruction to obtain current voiceprint characteristics;
specifically, after receiving the account verification request, the voice assistant performs voiceprint verification of the user, specifically, after the vehicle device prompts according to the first prompt information, the user sends a current voice instruction (for example, "login account"), and the voice assistant acquires the current voice instruction and performs voice recognition on the current voice instruction to obtain a corresponding current voiceprint feature.
Step S3, the voice assistant acquires pre-stored voiceprint characteristics associated with the account information, matches the pre-stored voiceprint characteristics with the current voiceprint characteristics, and if the pre-stored voiceprint characteristics are consistent with the current voiceprint characteristics, sends a successful recognition result to the vehicle APP;
specifically, when user account 1 successfully registers voiceprint, voice assistant can store the pre-stored voiceprint feature associated with the account information, and when the pre-stored voiceprint feature is voiceprint registration, the voiceprint feature of the user recorded by the voice assistant, so that the voice assistant can determine that voiceprint verification is successful and generate a successful recognition result and send the result to the car-mounted device APP by matching the pre-stored voiceprint feature with the current voiceprint feature, and if the pre-stored voiceprint feature is consistent with the current voiceprint feature, the current user and the account 1 selected by the user to log in are indicated, and voiceprint registration is successfully performed in advance.
Step S4, when the vehicle APP receives the successful recognition result, the vehicle APP obtains a voiceprint information associated certificate corresponding to the account information, sends the voiceprint information associated certificate to a server to carry out a login request, and receives an authentication result returned by the server in response to the login request; the voiceprint information associated certificate is cached in the vehicle machine in advance, and the authentication result is obtained by the server performing login authentication according to the voiceprint information associated certificate and the voiceprint information associated certificate cached in advance by the server;
specifically, when voiceprint registration of a user account 1 is successful, the car machine caches a voiceprint information association credential keytone 1 associated with the account 1, the voiceprint information association credential keytone 1 is a credential for performing an imperceptible login corresponding to the account 1, after receiving a recognition success result of a voice assistant, the car machine APP acquires keytone 1 associated with the account 1 according to the account 1, and sends the keytone 1 to a server of a car Service Provider (TSP) for performing a login request, after receiving the keytone 1, the server matches keytone 1 with keytone pre-stored at one end of the server, and if the matching is consistent, authentication is successful.
Illustratively, when the vehicle APP sends the Keytoken1 to the server to perform a login request, the VIN code of the vehicle is also sent to the server, the server acquires one or more Keytokens pre-stored at one end of the server according to the received VIN code, matches the one or more Keytokens with Keytoken1, if one end of the server has one Keytoken matched with Keytoken1, the authentication is successful, and the server sends the authentication result to the vehicle of the corresponding vehicle according to the VIN code of the vehicle.
And step S5, when the vehicle APP receives the authentication result returned by the server and is successful, logging in the vehicle account according to the account information.
Specifically, when the car machine APP receives that the authentication result returned by the server is successful, the current account 1 has the login authority, and then the car machine APP automatically logs in the car machine account 1.
Based on the above description, in this embodiment, after the user account successfully performs voiceprint registration, the subsequent vehicle-mounted account login needs to select the login account, and thus the vehicle can be logged in a non-sensitive manner by recognizing the voiceprint of the user.
In a preferred embodiment, the step S3 further includes: if the pre-stored voiceprint features are not matched with the current voiceprint features in a consistent manner, the voice assistant sends a recognition failure result to the vehicle APP; and when the vehicle APP receives the recognition failure result, outputting second prompt information for prompting the user to resend the preset voice instruction.
Specifically, the account 1 is taken as an example to be described, and when the pre-stored voiceprint features are not matched with the current voiceprint features, it is indicated that the account 1 selected by the user to log in has not been voiceprint registered in advance, or the content of the voice instruction sent by the user currently is wrong and is not the preset content of the voice instruction, for example, "login account". Therefore, a second prompt message is output to prompt the user to issue a preset voice command again, such as "login account".
After outputting the second prompt information, the voice assistant reacquires the current voice command sent by the user, performs voice recognition on the current voice command to obtain the current voiceprint feature, and then continues to execute steps S3-S5 according to the reacquired current voiceprint feature until the current voiceprint feature is successful, or the user stops the non-sensitive login process, or the number of recognition failures reaches a preset number of times, for example, 5 times, then the non-sensitive login is not allowed currently.
The specific process of noninductive logging in the car machine account number 1 can refer to fig. 2.
In a preferred embodiment, the voiceprint information associated credential pre-cached in the car APP in step S4 is specifically a voiceprint information associated credential generated by the server in response to the account associated voiceprint request of the car APP when the user performs user voiceprint registration in a login state in advance.
Referring to fig. 3, the pre-registering the user voiceprint in the login state by the user includes:
step S01, when the user is in account login, the vehicle APP receives a voiceprint registration request input by the user, and outputs third prompt information for prompting the user to send a preset voice instruction according to the voiceprint registration request;
step S02, the voice assistant acquires a current voice instruction sent by a user, performs voice recognition on the current voice instruction to obtain a voiceprint feature to be recorded, associates the voiceprint feature to be recorded with current login account information, stores the voiceprint feature to be recorded and the current login account information to obtain a prestored voiceprint feature, and returns a voiceprint recording success result to the vehicle APP;
step S03, when the vehicle APP receives the voiceprint recording success result, the vehicle APP sends an account number associated voiceprint request to a server, and receives a voiceprint information associated certificate returned by the server;
and step S04, the vehicle APP associates the voiceprint information association certificate returned by the server with the currently logged account information and then caches the voiceprint information association certificate in the vehicle.
Specifically, through voiceprint registration, an association relationship among a user voiceprint feature, a user account and a voiceprint information association certificate can be established, wherein the voiceprint information association certificate is used as a certificate of login authority, when a subsequent user account logs in, the user voiceprint can be identified only by selecting the login account, and as long as the voiceprint feature of the user is matched with the account selected by the user to log in, login authentication can be carried out on the vehicle through the voiceprint information association certificate and a server, and finally, the vehicle can log in without sense, so that more convenient and safer login experience is provided for a vehicle owner.
In a preferred embodiment, the third prompt message is specifically used to prompt the user to repeatedly send a preset voice command, such as "please say 5 login accounts";
wherein, the step S02 specifically includes:
the voice assistant acquires a plurality of voice instructions sent by a user, performs voice recognition on the voice instructions to obtain a plurality of voiceprint characteristics, and obtains the voiceprint characteristics to be recorded according to the voiceprint characteristics.
Specifically, if only the voiceprint feature of one voice command is collected, there may be a problem of inaccuracy, because the voice of the user speaking sometimes changes, for example, the speaking speed and the speaking voice all affect the extraction of the voiceprint feature, therefore, in this embodiment, 5 preset voice commands (for example, a fixed word of a login account) that the user repeatedly speaks are obtained, 5 corresponding voiceprint features can be obtained by performing voice recognition, according to the 5 voiceprint features, mean value processing or other calculation processing can be performed, a to-be-recorded voiceprint feature that can better represent the voiceprint features of the user is obtained, and the accuracy of subsequent voiceprint recognition is improved.
