Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of an identity authentication method based on voiceprint pattern identification according to an embodiment of the present invention, and as shown in fig. 1, the method includes:
step S01, receiving a service request sent by the user terminal, where the service request at least includes an authentication voice and a user identifier.
In the "instant authentication" mode, since the user can perform voice authentication only at a designated place, it is impossible to control the surrounding voice environment and security. In the embodiment of the invention, before the user initiates the service according to the self requirement, the user can firstly send the service request, such as an ATM money-taking request, an electronic door lock-unlocking request and the like, to the authentication server through the user terminal, such as a mobile phone or a fixed telephone and the like. Since the service request is sent in advance through the user terminal, the user can freely select a voice environment more concealed, secure, or more suitable for voice authentication to send the service request.
The service request comprises at least authentication voice and user identification. Of course, the specific process may also be executed in two steps, where a service request with a user identifier is sent to the authentication server through the user terminal, and then after receiving the agreement information replied by the authentication server, the authentication voice is recorded and sent to the authentication server through a voice collecting device of the user terminal, such as a microphone of a mobile phone or a fixed telephone.
And step S02, obtaining authentication voiceprint information according to the authentication voice, and comparing the authentication voiceprint information with pre-stored reserved voiceprint information which is uniquely corresponding to the user identification to obtain confidence.
After receiving the service request, the authentication server analyzes the authentication voice to extract the authentication voiceprint information. And meanwhile, pre-stored reserved voiceprint information which is uniquely corresponding to the user identification is found in the database according to the user identification in the received service request. And comparing the authentication voiceprint information with the reserved voiceprint information, and obtaining the score of the confidence coefficient according to the similarity of the authentication voiceprint information and the reserved voiceprint information.
And step S03, if the confidence is greater than a preset confidence threshold, generating a graphic identifier corresponding to the user identifier and sending the graphic identifier to the user terminal, and meanwhile, setting the authentication time range of the graphic identifier.
The authentication server compares the obtained confidence with a preset confidence threshold, if the confidence is less than or equal to the confidence threshold, the service request is judged to be failed, and an instruction for re-acquiring the authentication voice can be sent to the user terminal, so that the user terminal acquires new authentication voice through the voice acquisition equipment to recalculate the confidence until the confidence is greater than the confidence threshold. Of course, after determining that the service request fails, the authentication server may also send a service request failure identifier to the user terminal, so that the user terminal re-initiates the service request.
And if the confidence obtained by the authentication server is greater than the confidence threshold, judging that the authentication is successful. At this time, a graphic identifier, such as a bar code or a two-dimensional code, corresponding to the user identifier may be generated. The graphic identifier may be a graphic identifier obtained through a random sequence, and does not include any specific information, and may also be obtained according to information such as a user identifier, and is not specifically limited herein.
Meanwhile, an authentication time range of the graphical identifier needs to be set, for example, half an hour, 1 hour, and the like, and the authentication time range may be preset by the authentication server according to a service request sent by the user, or may be specified by the user through the user terminal, for example, 1:45 to 2:15 in the afternoon.
Then the authentication server will associate the obtained graphic identification and authentication time range with the user identification and store them in the database, and at the same time, send success request information to the user terminal, the success request information at least includes the graphic identification, so that the user terminal and the authentication server realize the synchronization of the graphic identification. Of course, the successful request information may also include information such as an authentication time range.
Step S04, if the identity authentication information sent by the user terminal is received in the authentication time range, the authentication is judged to be successful; wherein the identity authentication information at least comprises the graphic identification.
The user sends a service execution request to the authentication server at a place where the user transacts services, such as in front of an ATM or a door lock, where the service execution request may be sent through a system terminal of the authentication server, such as an ATM, or may be sent directly through a user terminal.
The authentication server sends an identity authentication request to the user terminal or the system terminal, and the image acquisition equipment of the system terminal receives identity authentication information from the user terminal, wherein the identity authentication information comprises the graphic identifier and is sent to the authentication server.
And the authentication server compares the received graphic identification with the graphic identification in the database, and if the received graphic identification is the same as the graphic identification in the database and the current moment is within the corresponding authentication time range, the authentication server judges that the identity authentication is successful and can execute the corresponding service.
If the graphical identifiers are different or the current moment is not within the authentication time range, the identity authentication is judged to be failed, and an identity authentication failure instruction is sent to the user terminal, wherein the identity authentication failure instruction can also comprise a failure reason and a further operation instruction. For example, if the graphical identifiers are different, the identity authentication request can be retransmitted, so that the user terminal retransmits the identity authentication information; and if the current time exceeds the end time of the authentication time range, the graphical identifier is invalid, and a user terminal needs to initiate a service request again to acquire a new graphical identifier. And if the current time does not reach the beginning of the authentication time range, the user terminal can be prompted to indicate the authentication time range. Of course, after the identity authentication is determined to fail, the mode may be switched to the "instant authentication" mode immediately.
The embodiment of the invention verifies whether the authentication voice is successfully authenticated or not by receiving the service request which is sent by the user terminal and contains the authentication voice and the user identification through the authentication server, and if the authentication voice is successfully authenticated, the corresponding graphic identification is generated and sent to the user terminal, so that the user can safely and reliably realize the identity authentication through the graphic identification of the user terminal within the preset authentication time range.
Fig. 2 is a flowchart of another identity authentication method based on voiceprint pattern identification according to an embodiment of the present invention, and as shown in fig. 2, before the step S01, the method further includes:
step S011, receiving the registration information sent by the user terminal, wherein the registration information at least comprises the user identification and the reserved voice.
Before a user requests a service through a user terminal, the user needs to register with an authentication server. Specifically, registration information may be sent to the authentication server through the user terminal, where the registration information at least includes the user identifier and the reserved voice. The user identifier may be a user ID, a user mobile phone number, or a user mailbox set by the user. The reserved voice may be a phrase or sentence as required by the authentication server.
Of course, step S011 may also be performed in two steps, sending the registration request, setting the user identifier, and then collecting the reserved voice by using the voice collecting device of the user terminal according to the instruction of the authentication server.
And step S012, obtaining the reserved voiceprint information according to the reserved voice.
After receiving the registration information, the authentication server analyzes the reserved voice according to a preset voice extraction rule to obtain reserved voiceprint information. And then storing the user identification and the corresponding reserved voiceprint information into a database after the user identification and the corresponding reserved voiceprint information are associated.
The embodiment of the invention verifies whether the authentication voice is successfully authenticated or not by receiving the service request which is sent by the user terminal and contains the authentication voice and the user identification through the authentication server, and if the authentication voice is successfully authenticated, the corresponding graphic identification is generated and sent to the user terminal, so that the user can safely and reliably realize the identity authentication through the graphic identification of the user terminal within the preset authentication time range.
Based on the above embodiment, further, the graphic identifier includes any combination of the user identifier, reserved voiceprint information, and authentication time range.
The graphical identifier generated by the authentication server may be generated according to a random sequence, or may be generated according to a sequence of any combination of the user identifier, the reserved voiceprint information, and the authentication time range, and the generated graphical identifier includes the above information, thereby simplifying the subsequent identity authentication process.
For example, if the graphical identifier includes a user identifier and an authentication time range, at this time, the system terminal may directly acquire the user identifier and the authentication time range by acquiring the graphical identifier on the user terminal, and send the user identifier and the authentication time range to the authentication server for identity authentication, without waiting for an identity authentication request sent by the authentication server to be acquired.
The generation rule and the contained information of the specific graphic identifier may be set according to actual needs, and are not specifically limited herein.
The embodiment of the invention verifies whether the authentication voice is successfully authenticated or not by receiving the service request which is sent by the user terminal and contains the authentication voice and the user identification through the authentication server, and if the authentication voice is successfully authenticated, the corresponding graphic identification is generated and sent to the user terminal, so that the user can safely and reliably realize the identity authentication through the graphic identification of the user terminal within the preset authentication time range.
Based on the above embodiment, further, the service request further includes a service type; correspondingly, the graphic identifier also comprises a service type.
In order to be able to increase security and further simplify the identity authentication procedure, the user terminal sends a service request to the authentication server, said service request also comprising the type of service, e.g. money to be taken and/or transferred. The authentication server stores the service type in a database, and the service type is contained in the graph identifier when the graph identifier is generated after the voice authentication is completed. Therefore, when the identity authentication information is sent to the authentication server by the subsequent user terminal, the service type in the acquired graphic identifier can be obtained through analysis, and the service type is compared with the service type in the database, so that the correctness of the graphic identifier is further verified, and the corresponding service operation is started to be executed at the same time, and other service types are not allowed to be executed.
The embodiment of the invention verifies whether the authentication voice is successfully authenticated or not by receiving the service request which is sent by the user terminal and contains the authentication voice, the user identifier and the service type through the authentication server, and if the authentication voice is successfully authenticated, the corresponding graphic identifier is generated and sent to the user terminal, so that the user can safely and reliably realize the identity authentication through the graphic identifier of the user terminal within the preset authentication time range.
Fig. 3 is a flowchart of another identity authentication method based on voiceprint pattern identification according to an embodiment of the present invention, and as shown in fig. 3, the method includes:
step S10, a service request is sent to an authentication server, the service request at least comprises authentication voice and user identification, so that the authentication server obtains authentication voiceprint information according to the authentication voice and compares the authentication voiceprint information with pre-stored reserved voiceprint information uniquely corresponding to the user identification to obtain confidence, if the confidence is greater than a preset confidence threshold, a graphic identification corresponding to the user identification is generated, and meanwhile, the authentication time range of the graphic identification is set.
Before a user initiates a service according to the self requirement, the user firstly sends a service request to an authentication server through a user terminal. The service request comprises at least authentication voice and user identification. The specific process can be executed in two steps, firstly, a service request with a user identifier is sent to an authentication server through a user terminal, and then after receiving agreement information replied by the authentication server, the authentication voice is recorded through voice acquisition equipment of the user terminal and sent to the authentication server.
After receiving the service request, the authentication server analyzes the authentication voice to extract the authentication voiceprint information. And meanwhile, pre-stored reserved voiceprint information which is uniquely corresponding to the user identification is found in the database according to the user identification in the received service request. And comparing the authentication voiceprint information with the reserved voiceprint information, and obtaining the score of the confidence coefficient according to the similarity of the authentication voiceprint information and the reserved voiceprint information.
The authentication server compares the obtained confidence with a preset confidence threshold, if the confidence is less than or equal to the confidence threshold, the service request is judged to be failed, and an instruction for re-acquiring the authentication voice can be sent to the user terminal, so that the user terminal acquires new authentication voice through the voice acquisition equipment to recalculate the confidence until the confidence is greater than the confidence threshold. Of course, after determining that the service request fails, the authentication server may also send a service request failure identifier to the user terminal, so that the user terminal re-initiates the service request.
And if the confidence obtained by the authentication server is greater than the confidence threshold, judging that the authentication is successful. At this point, a graphical identifier corresponding to the user identifier may be generated.
Meanwhile, an authentication time range of the graphical identifier needs to be set, and the authentication time range can be preset by the authentication server according to a service request sent by a user or can be specified by the user through a user terminal.
And step S11, receiving the graphic identifier sent by the authentication server.
Then the authentication server will associate the obtained graphic identification and authentication time range with the user identification and store them in the database, and at the same time, send success request information to the user terminal, the success request information at least includes the graphic identification, so as to realize the synchronization of the graphic identification between the user terminal and the authentication server. Of course, the successful request information may also include information such as an authentication time range.
Step S12, sending identity authentication information to the authentication server within the authentication time range, so that the authentication server determines that the authentication is successful; wherein the identity authentication information at least comprises the graphic identification.
The user sends a service execution request to the authentication server at a place where the user transacts the service, wherein the service execution request can be sent through a system terminal of the authentication server or directly sent through a user terminal.
The authentication server sends an identity authentication request to the user terminal or the system terminal, and the image acquisition equipment of the system terminal receives identity authentication information from the user terminal, wherein the identity authentication information comprises the graphic identifier and is sent to the authentication server.
And the authentication server compares the received graphic identification with the graphic identification in the database, and if the received graphic identification is the same as the graphic identification in the database and the current moment is within the corresponding authentication time range, the authentication server judges that the identity authentication is successful and can execute the corresponding service.
If the graphical identifiers are different or the current moment is not within the authentication time range, the identity authentication is judged to be failed, and an identity authentication failure instruction is sent to the user terminal, wherein the identity authentication failure instruction can also comprise a failure reason and a further operation instruction. For example, if the graphical identifiers are different, the identity authentication request can be retransmitted, so that the user terminal retransmits the identity authentication information; and if the current time exceeds the end time of the authentication time range, the graphical identifier is invalid, and a user terminal needs to initiate a service request again to acquire a new graphical identifier. And if the current time does not reach the beginning of the authentication time range, the user terminal can be prompted to indicate the authentication time range. Of course, after the identity authentication is determined to fail, the mode may be switched to the "instant authentication" mode immediately.
The embodiment of the invention verifies whether the authentication voice is successfully authenticated or not by receiving the service request which is sent by the user terminal and contains the authentication voice and the user identification through the authentication server, and if the authentication voice is successfully authenticated, the corresponding graphic identification is generated and sent to the user terminal, so that the user can safely and reliably realize the identity authentication through the graphic identification of the user terminal within the preset authentication time range.
Based on the above embodiment, further, before the step S10, the method further includes:
and sending registration information to an authentication server, wherein the registration information at least comprises the user identification and reserved voice, so that the authentication server obtains the reserved voiceprint information according to the reserved voice.
Before a user requests a service through a user terminal, the user needs to register with an authentication server. Specifically, registration information may be sent to the authentication server through the user terminal, where the registration information at least includes the user identifier and the reserved voice.
Of course, the above process may also be performed in two steps, first sending the registration request, and setting the user identifier, and then collecting the reserved voice by using the voice collecting device of the user terminal according to the instruction of the authentication server.
After receiving the registration information, the authentication server analyzes the reserved voice according to a preset voice extraction rule to obtain reserved voiceprint information. And then storing the user identification and the corresponding reserved voiceprint information into a database after the user identification and the corresponding reserved voiceprint information are associated.
The embodiment of the invention verifies whether the authentication voice is successfully authenticated or not by receiving the service request which is sent by the user terminal and contains the authentication voice and the user identification through the authentication server, and if the authentication voice is successfully authenticated, the corresponding graphic identification is generated and sent to the user terminal, so that the user can safely and reliably realize the identity authentication through the graphic identification of the user terminal within the preset authentication time range.
Further, the embodiment of the present invention specifically exemplifies the services of cash withdrawal, transfer and the like of a bank ATM, and the specific flow is as follows:
1. when the voice print registration method is used for the first time, a user completes the registration process through a user terminal or in a bank to complete the acquisition of reserved voice print information;
2. before the user performs related banking services, voiceprint authentication is completed according to self conditions (anytime and anywhere) to generate a voiceprint graphic identifier;
3. the user presents the voiceprint graphic identification, the ATM scans and analyzes the voiceprint graphic identification of the user, and if the authentication is passed, the service is started; otherwise, the service is closed.
