And step S21, the intelligent double-recording terminal responds to the user operation and sends an intelligent double-recording communication request for opening the intelligent double-recording authority to the intelligent double-recording server.
In this embodiment, the user operation may be a voice operation or a touch operation, which is not limited herein. The intelligent double-recording permission is used for representing the permission of double-recording information transmission between the intelligent double-recording terminal and the intelligent double-recording server, and the intelligent double-recording communication request is used for requesting the intelligent double-recording server to initiate identity authentication.

In this embodiment, the authentication information includes voice information, fingerprint information, and face image information. In some embodiments, other biometric information may also be included.
And step S24, the intelligent double-recording server checks the identity verification information, judges whether the intelligent double-recording terminal passes the verification, and sends authentication information to the intelligent double-recording terminal when the intelligent double-recording terminal passes the verification.
In this embodiment, the authentication information is used to indicate that the intelligent dual-recording terminal passes the verification.
And step S25, after receiving the authentication information, the intelligent double-recording terminal responds to the double-recording operation of the user to perform double recording on the user, and sends the obtained current double-recording information to the intelligent double-recording server for processing.
In this embodiment, the double recording operation may also be a voice operation or a touch operation.
It can be understood that, by executing the above steps S21-S25, the intelligent dual recording terminal sends an intelligent dual recording communication request for opening the intelligent dual recording right to the intelligent dual recording server, the intelligent dual recording server initiates a user authentication request to the intelligent dual recording terminal after completing verification according to the intelligent dual recording communication request, the intelligent dual recording terminal transmits recorded authentication information to the intelligent dual recording server, the intelligent dual recording server verifies the authentication information and sends authentication information to the intelligent dual recording terminal when determining that the intelligent dual recording terminal passes the verification, the intelligent dual recording terminal performs dual recording on the user after receiving the authentication information and sends the obtained current dual recording information to the intelligent dual recording server for processing. Therefore, before the intelligent double-recording communication service interaction, the intelligent double-recording server and the intelligent double-recording terminal can carry out communication verification through the biological characteristic information of the user, so that accurate and reliable communication verification is realized, and the subsequent intelligent double-recording service handling efficiency is ensured.
In a specific embodiment, the inventor finds that, in order to implement reliable verification of the encrypted authentication signature and avoid errors or deviations during verification, the intelligent dual-record server needs to consider the association between request messages when analyzing the intelligent dual-record communication request, so as to ensure the integrity of the encrypted authentication signature obtained by analysis. To improve this purpose, in step S22, the intelligent dual-recording server parses the intelligent dual-recording communication request to obtain the encrypted authentication signature of the intelligent dual-recording terminal carried in the intelligent dual-recording communication request, which may specifically include the contents described in the following step S221-step S224.
Step S221, parsing the intelligent dual-recording communication request to obtain request packet distribution information and multiple groups of request packet frames in the intelligent dual-recording information request, querying whether a service request tag and a non-service request tag exist in the request packet distribution information, and determining a first request packet frame located under the service request tag and a second request packet frame located under the non-service request tag in the multiple groups of request packet frames on the premise that the service request tag and the non-service request tag exist in the request packet distribution information.
Step S222, calculating a correlation coefficient between a first request packet frame in the plurality of groups of request packet frames under the service request label and a second request packet frame in the plurality of groups of request packet frames under the non-service request label based on a first request packet frame in the plurality of groups of request packet frames under the service request label and a packet identification degree of the first request packet frame, and generating a correlation coefficient matrix between the service request label and the non-service request label according to the calculated correlation coefficient.
Step S223, for each matrix element in the correlation coefficient matrix, determining a first mapping element value of the matrix element in the first characteristic queue corresponding to the service request tag and a second mapping element value of the matrix element in the second characteristic queue corresponding to the non-service request tag, and migrating at least a part of the first request packet frame under the service request tag to the non-service request tag based on a matching degree between the first mapping element value and the second mapping element value corresponding thereto.
Step S224, generating a packet frame transmission path of the first request packet frame under the service request label, extracting a difference value between an execution function of each path node in the packet frame transmission path and an execution parameter output value of an execution function of a previous path node of the path node, extracting a packet feature set of the first request packet frame under the service request label on a time sequence according to the difference value, determining a target feature corresponding to the encryption authentication signature from the packet feature set, and obtaining the encryption authentication signature based on the target feature.
In this way, based on the contents described in the above steps S221 to S224, the association between the request messages can be considered when the intelligent double-record communication request is analyzed, so as to ensure the integrity of the encrypted authentication signature obtained by analysis, and avoid errors or deviations when the encrypted authentication signature is subsequently verified.
In one possible implementation, in order to achieve accurate verification of the cryptographic authentication signature, in step S22, the smart dual-directory server may achieve verification of the cryptographic authentication signature through the following steps a-c.
Step a, sequentially extracting a plurality of continuous signature message frames in the encryption authentication signature according to a time sequence, determining the authentication category to which each signature message frame belongs, respectively setting category weights for the determined authentication categories on the basis of a distribution queue of a key random number of an encryption key corresponding to the encryption authentication signature, and after the category weights are set, sequencing the signature message frames according to the descending order of the category weights to obtain a message frame sequencing queue.
Step b, obtaining the sequencing position information of each signature message frame in the message frame sequencing queue, and determining the authentication reliability of each signature message frame on the time sequence through the mapping information of the sequencing position information in a preset signature authentication locus diagram; for the signature message frame with the authentication reliability lower than the set reliability, judging whether the authentication reliability of the previous signature message frame of the signature message frame in the message frame sequencing queue and the authentication reliability of the next signature message frame of the signature message frame in the message frame sequencing queue are both lower than the set reliability; under the premise that the authentication reliability of the previous signature message frame of the signature message frame in the message frame sorting queue and the authentication reliability of the next signature message frame of the signature message frame in the message frame sorting queue are both smaller than the set reliability, marking the signature message frame, the previous signature message frame corresponding to the signature message frame and the next signature message frame corresponding to the signature message frame by adopting a first reliability identifier; under the premise that the authentication reliability of the previous signature message frame of the signature message frame in the message frame sorting queue and the authentication reliability of the next signature message frame of the signature message frame in the message frame sorting queue are not uniform and are less than the set reliability, marking the signature message frame, the previous signature message frame corresponding to the signature message frame and the next signature message frame corresponding to the signature message frame by adopting a second reliability identifier; the first credibility mark is a mark corresponding to an abnormal signature, and the second credibility mark is a mark corresponding to normal credibility.
Step c, listing the credibility marks corresponding to each signature message frame in the message frame sorting queue according to the sorting of the message frame sorting queue to form a credibility mark queue, and calculating the current occupation ratio of the second credibility marks in the credibility mark queue; judging whether the current ratio of the second credibility identifier in the credibility identifier queue reaches a set ratio; when the current ratio of the second credibility identifier in the credibility identifier queue reaches the set ratio, determining that the encryption authentication signature passes verification; and when the current duty ratio of the second credibility identifier in the credibility identifier queue does not reach the set duty ratio, determining that the encrypted authentication signature does not pass verification.
It will be appreciated that based on the description of steps a-c above, accurate verification of the cryptographic authentication signature can be achieved.
In one example, in order to ensure the accuracy of recording the authentication information, it is necessary to consider and remove noise information when recording the information, and perform adaptive completion on the locally defective authentication information, and to achieve this, in step S23, the intelligent dual-recording terminal starts an authentication recording thread to record the authentication information of the user, which may specifically include the contents described in steps S231-S234 below.
Step S231, in the process of recording the identity authentication information, identifying the current biological characteristic category of the current identity authentication information; the biological feature classes comprise a first biological feature class used for representing voice features of a user, a second biological feature class used for representing fingerprint features of the user and a third biological feature class used for representing face images of the user.
Step S232, when the current biological characteristic category is the first biological characteristic category, extracting an amplitude-frequency curve of the current authentication information and determining curve characteristic data of the amplitude-frequency curve at a plurality of different pause time nodes, calculating a voiceprint defect curve corresponding to the amplitude-frequency curve according to the curve characteristic data, correcting the amplitude-frequency curve by adopting the voiceprint defect curve to obtain a target amplitude-frequency curve, and completing the current authentication information based on the target amplitude-frequency curve.
Step S233, when the current biometric feature category is the second biometric feature category, extracting a first image feature matrix of the current authentication information used for characterizing fingerprint line distribution of a user and a second image feature matrix of a discontinuous line used for characterizing the fingerprint line distribution, and determining matrix units with different feature weights in the first image feature matrix and the second image feature matrix; mapping a matrix parameter corresponding to any one matrix unit in the first image characteristic matrix to a target matrix unit with the maximum characteristic weight in the second image characteristic matrix to obtain a mapping parameter, determining a matrix fusion list between the first image characteristic matrix and the second image characteristic matrix based on the matrix parameter and the mapping parameter, performing fusion correction on the first image characteristic matrix and the second image characteristic matrix according to the matrix fusion list to obtain a third image characteristic matrix, and completing the current identity verification information based on the third image characteristic matrix.
Step S234, when the current biological feature type is the third biological feature type, extracting a face recognition result corresponding to the current identity verification information and weighting a plurality of recognition dimension indexes corresponding to the face recognition result to obtain a target dimension index; and when the index weight corresponding to the target dimension index is smaller than the set weight, correcting the face recognition result according to a preset correction model so as to complete the current identity authentication information.
It can be understood that, by performing the above steps S231 to S234, the noise information can be considered and removed when recording the information, and the locally missing authentication information can be adaptively complemented, so that the accuracy of recording the authentication information can be ensured.
In practical applications, the inventor finds that, in order to ensure complete verification of the authentication information when verifying the authentication information, in step S24, the intelligent dual-recording server verifies the authentication information, and determines whether the intelligent dual-recording terminal passes the authentication, and further includes the following contents described in step S241 to step S243.
