Therefore, the biological feature identification results with different biological feature dimensions can be analyzed, so that the access authority configuration list and the information authority matching result can be determined relatively independently based on different biological feature identification results, the influence deviation between the access authority configuration list and the information authority matching result can be ensured not to be overlarge, the reliability of the information authority matching result can be improved, and the accuracy of the difference value between the target authority security level and each candidate authority security level in the preset security level queue can be ensured. Therefore, when a plurality of candidate permission safety levels are selected, the candidate permission safety levels corresponding to the information access path related to the payment terminal to be detected can be selected as much as possible, so that when the information safety risk of the payment terminal to be detected is judged based on the information access path, different biological characteristics identified by the payment terminal to be detected can be comprehensively considered, the reliability of information safety risk detection is improved, the information safety of the payment terminal to be detected during online payment is ensured, and the privacy information and important information stored in the payment terminal to be detected are prevented from being stolen.

In some examples, the selecting n candidate privilege security levels from the preset security level queue based on the difference between the target privilege security level and each candidate privilege security level as described in step S33 may include the following: and selecting n candidate permission security levels with the largest difference from the preset security level queue based on the difference between the target permission security level and each candidate permission security level in the preset security level queue.

In practical application, in order to comprehensively consider different biological characteristics identified by the payment terminal to be detected so as to improve the reliability of information security risk detection, the biological characteristic similarity rates corresponding to different detection time nodes need to be considered, so that the instantaneous variability of the biological characteristics is considered. To achieve this, in step S33, it is determined whether the payment terminal to be detected has information security risk based on the information access paths of the n candidate privilege security levels, which may exemplarily include the contents described in the following steps S331 to S336.

Step S331, based on the path similarity between every two adjacent information access paths in the information access paths of the n candidate permission security levels, determining a current index information set used for calculating the comprehensive security level corresponding to the n candidate permission security levels.

Step S332, based on the current index information set, obtaining a to-be-detected index data set corresponding to each payment detection time node of the to-be-detected payment terminal in a first set payment detection time period, where the first set payment detection time period includes at least two payment detection time nodes, and the to-be-detected index data set corresponding to each payment detection time node includes the network index parameters of the payment network collected or calculated by the payment network parameter verification unit in the to-be-detected payment terminal in the corresponding payment detection time node.

Step S333, determining a biological feature similarity rate between the to-be-detected index data sets corresponding to each payment detection time node in the first set payment detection time period.

Step S334, determining a payment behavior feature set of the payment terminal to be detected in the first set payment detection period according to the biological feature similarity between the to-be-detected index data sets corresponding to the payment detection time nodes in the first set payment detection period.

Step S335, determining the payment behavior evaluation index of the payment terminal to be detected in the first set payment detection time period according to the payment behavior feature set.

Step S336, calculating comprehensive security levels corresponding to the n candidate permission security levels through the payment behavior evaluation index; judging whether the comprehensive security level is greater than a set security level; determining that the payment terminal to be detected has no information security risk when the comprehensive security level is judged to be greater than or equal to the set security level; and determining that the payment terminal to be detected has information security risk when the comprehensive security level is judged to be smaller than the set security level, and locking the payment behavior interface of the payment terminal to be detected when the payment terminal to be detected has information security risk.

Thus, by applying the contents described in the above steps S331 to S336, the payment behavior feature set of the payment terminal to be detected in the first set payment detection period can be determined according to the biological feature similarity between the to-be-detected index data sets corresponding to the nodes at the time of payment detection in the first set payment detection period, and the payment behavior evaluation index of the payment terminal to be detected in the first set payment detection period can be determined according to the payment behavior feature set, so that the comprehensive security level is calculated based on the payment behavior evaluation index, and thus the biological feature similarity corresponding to the nodes at different times of payment detection can be considered, so that the instantaneous variability of the biological features is considered, and further, different biological features identified by the payment terminal to be detected are comprehensively considered. It can be understood that whether the payment terminal to be detected has the information security risk or not is detected through the comprehensive security level, and the reliability of information security risk detection can be improved.

Further, the acquiring of the to-be-detected index data set corresponding to each payment detection time node of the to-be-detected payment terminal in the first set payment detection period described in step S332 may be implemented by the following contents described in steps S3321 to S3324.

Step S3321, acquiring the network index parameters of the payment network acquired by the payment network parameter verification unit in the payment terminal to be detected in the set time interval after the first payment detection time node starts, and determining the data set of the to-be-detected index corresponding to the first payment detection time node according to the network index parameters of the payment network acquired by the payment network parameter verification unit in the payment terminal to be detected in the set time interval after the first payment detection time node starts, wherein the first payment detection time node is any one payment detection time node in the first set payment detection time interval.

Step S3322, when the payment network parameter verification unit in the payment terminal to be detected does not acquire the network index parameter of the payment network within a set time interval after a second payment detection time node starts, determining a data set of the to-be-detected index corresponding to the second payment detection time node according to the network index parameter of the payment network calculated by the payment network parameter verification unit in the payment terminal to be detected, where the second payment detection time node is any payment detection time node other than the first payment detection time node within the first set payment detection time interval.

Step S3323, the payment network parameter checking unit in the payment terminal to be detected does not collect the network index parameters of the payment network within the set time interval after the third payment detection time node starts, and the data sets of the indexes to be detected corresponding to the first set number of payment detection time nodes which are continuous before the third payment detection time node are all determined according to the network index parameters of the payment network calculated by the payment network parameter verification unit, sending payment network acquisition instructions to the payment network parameter verification unit, so that the payment network parameter verification unit collects the network index parameters of the payment network in response to the payment network collection instruction, the third payment detection time node is any payment detection time node except the first payment detection time node and the second payment detection time node in the first set payment detection time period.

Step S3324, acquiring the network index parameters of the payment network collected by the payment network parameter verification unit in response to the payment network acquisition instruction, and determining the to-be-detected index data set corresponding to the third payment detection time node according to the network index parameters of the payment network collected by the payment network parameter verification unit in response to the payment network acquisition instruction.

It can be understood that, by executing the steps S3321 to S3324, the data set of the to-be-detected indicator corresponding to different time nodes for payment detection can be completely determined, so as to provide sufficient data basis for the subsequent calculation of the comprehensive security level, and ensure the reliability of the subsequent calculation of the comprehensive security level.

Further, the determining of the biological feature similarity between the to-be-detected index data sets corresponding to the payment detection time nodes in the first set payment detection period in step S334 may be implemented by the following two implementation manners.

In the first implementation mode, a dynamic network index parameter set is determined from index data sets to be detected corresponding to each payment detection time node in a first set payment detection time period; and respectively determining the biological feature similarity between each index data set to be detected, except the dynamic network index parameter set, in the index data set to be detected corresponding to each payment detection time node in the first set payment detection time period and the dynamic network index parameter set.

In a second implementation manner, the biological feature similarity rates between the to-be-detected index data sets corresponding to every two adjacent payment detection time nodes in the first set payment detection time period are respectively determined.

It will be appreciated that the above-described embodiments of determining the biometric similarity ratio may alternatively be used to flexibly and quickly calculate the biometric similarity ratio.

On the basis of the above steps S331 to S336, the to-be-detected index data set corresponding to each payment detection time node in the first set payment detection time period includes a traceability index data set and a non-traceability index data set, and the payment behavior feature set includes a first payment behavior feature set determined according to the biological feature similarity rate corresponding to the traceability index data set of each payment detection time node specified in the first set payment detection time period, and a second payment behavior feature set determined according to the biological feature similarity rate corresponding to the non-traceability index data set of each payment detection time node specified in the first set payment detection time period. Based on this, the determining, according to the payment behavior feature set, the payment behavior evaluation index of the to-be-detected payment terminal in the first set payment detection time period in step S335 includes step S3350: and determining the payment behavior evaluation index of the payment terminal to be detected in the first set payment detection time period according to the first payment behavior feature set and the second payment behavior feature set.

Further, the determining, in step S3350, a payment behavior evaluation index of the to-be-detected payment terminal in the first set payment detection period according to the first set of payment behavior characteristics and the second set of payment behavior characteristics may further include the following steps S3351 to S3353.

Step S3351, determining the payment behavior evaluation index of the payment terminal to be detected in the first set payment detection time period as a first target evaluation index under the condition that the behavior feature difference coefficient corresponding to the first payment behavior feature set is not smaller than a preset first difference coefficient threshold and the behavior feature difference coefficient corresponding to the second payment behavior feature set is not smaller than a preset second difference coefficient threshold.

Step S3352, determining the payment behavior evaluation index of the payment terminal to be detected in the first set payment detection time period as a second target evaluation index, when the behavior feature difference coefficient corresponding to the first payment behavior feature set is not smaller than the first difference coefficient threshold, and the behavior feature difference coefficient corresponding to the second payment behavior feature set is smaller than the second difference coefficient threshold.

Step S3353, determining the payment behavior evaluation index of the payment terminal to be detected in the first set payment detection time period as a third target evaluation index under the condition that the behavior feature difference coefficient corresponding to the first payment behavior feature set is smaller than the first difference coefficient threshold and the behavior feature difference coefficient corresponding to the second payment behavior feature set is smaller than the second difference coefficient threshold.

Therefore, different third target evaluation indexes can be determined according to different behavior characteristic difference coefficients, and therefore the third target evaluation indexes are ensured to be matched with an actual payment service scene.

Further, the determining, in step S334, a payment behavior feature set of the payment terminal to be detected in the first set payment detection period according to the biological feature similarity rate between the to-be-detected index data sets corresponding to the payment detection time nodes in the first set payment detection period includes the following contents described in steps S3341 and S3342.

Step S3341, determining at least one target traceability index data set with the payment network reliability weight higher than a first set reliability weight threshold and at least one target non-traceability index data set with the payment network reliability weight higher than a second set reliability weight threshold from the to-be-detected index data sets corresponding to each payment detection time node in the first set payment detection time period.

Step S3342, determining the first payment behavior feature set according to the biological feature similarity corresponding to the at least one target traceability index data set, and determining the second payment behavior feature set according to the biological feature similarity corresponding to the at least one target non-traceability index data set.

In addition, the determining, according to the biological feature similarity between the to-be-detected index data sets corresponding to the payment detection time nodes in the first set payment detection period, the payment behavior feature set of the to-be-detected payment terminal in the first set payment detection period described in step S334 may also be implemented by the following implementation manners: determining the timeliness coefficient of each biological characteristic similarity according to the number of the to-be-detected index data contained in the to-be-detected index data set corresponding to each payment detection time node in the first set payment detection time period; and determining a payment behavior feature set of the payment terminal to be detected in the first set payment detection period according to the biological feature similarity between the to-be-detected index data sets corresponding to the payment detection time nodes in the first set payment detection period and the timeliness coefficient of each biological feature similarity.

It can be understood that the two further implementation manners for step S334 are implemented according to the payment network reliability weight and the timeliness coefficient, so that an implementation manner that is easy to implement can be flexibly selected according to an actual service scenario for implementation.

It is to be understood that the difference between the target permission security level of the information permission matching result determined in step S32 and each candidate permission security level in the preset security level queue may be implemented in any one of the following three embodiments.

In a first embodiment, the difference between the target privilege security level and the candidate privilege security level is determined based on the timing difference weight between the target privilege security level and the candidate privilege security level.

In a second embodiment, the difference between the target privilege security level and the candidate privilege security level is determined based on the access heat difference weight between the target privilege security level and the candidate privilege security level.

In a third embodiment, the difference between the target privilege security level and the candidate privilege security level is determined based on the intrusion risk level difference weight between the target privilege security level and the candidate privilege security level.

In one possible embodiment, in order to ensure that the target information right distribution of the payment terminal to be detected can cover the private data and the important data stored in the payment terminal to be detected, the determining, according to the access right configuration list of the second biometric identification result, of the target information right distribution of the payment terminal to be detected, as described in step S32, may further include implementing the following steps S321-S326.

Step S323, performing encryption and decryption verification by using the first dynamic key sequence corresponding to the access right combination, to obtain an encryption and decryption verification result of each information access identifier in the access right combination.

Step S324, based on the encryption and decryption verification result of each information access identifier in multiple access right combinations, performing key sequence adjustment on the first dynamic key sequence corresponding to the access right combination to obtain a first adjusted key sequence corresponding to the access right combination.

Step S325, add the first adjusted key sequence corresponding to the access right combination to the access verification key set corresponding to the access right combination.

Step S326, returning to and executing the step of determining a first dynamic key sequence corresponding to the access permission combination in the access verification key set corresponding to the access permission combination until the permission security evaluation coefficients corresponding to the multiple access permission combinations reach set coefficients; and when the authority security evaluation coefficients corresponding to the multiple access authority combinations reach the set coefficient, determining the target information authority distribution of the payment terminal to be detected based on the authority security evaluation coefficients and the multiple access authority combinations.

In this way, by applying the steps S321 to S326, iterative determination of the first dynamic key sequence can be realized, so that it is ensured that the permission security evaluation coefficients corresponding to multiple access permission combinations reach the set coefficient, and thus, target information permission distribution of the payment terminal to be detected can be determined based on the permission security evaluation coefficients and the multiple access permission combinations. The permission safety evaluation coefficient reaches a set coefficient, and the set coefficient is configured based on the private data and the important data stored in the payment terminal to be detected, so that the target information permission distribution of the payment terminal to be detected can cover the private data and the important data stored in the payment terminal to be detected by the method.

Further, the determining of the first dynamic key sequence corresponding to the access right combination in the access verification key set corresponding to the access right combination, which is described in step S322, may be exemplarily interpreted as the following step S3221-step S3224.

Step S3221, determining a second dynamic key sequence and a first static key sequence corresponding to the access right combination, and a first static key sequence corresponding to the target access right combination.

Step S3222, obtaining a first comparison result of the first static key sequence corresponding to the access right combination by performing bit-by-bit comparison on the first static key sequence corresponding to the access right combination and the first static key sequence corresponding to a target access right combination, where the target access right combination is all access right combinations including the access right combination in the multiple access right combinations.

Step S3223, obtaining a second comparison result of the first static key sequence of the access right combination by performing bit-by-bit comparison on the first static key sequence corresponding to the access right combination and the second dynamic key sequence corresponding to the access right combination.

Further, in the above step S3221, a first static key sequence corresponding to the target access right combination is determined, which includes the following contents: step S32211, acquiring an authority tag set of the target access authority combination, and determining an access authority activation record corresponding to the target access authority combination; step S32212, according to the authority label set of the target access authority combination, determining a first static key sequence corresponding to the target access authority combination in the access authority activation record corresponding to the target access authority combination.

In a further embodiment, the determination of the access right activation record corresponding to the target access right combination described in step S32211 may be implemented by the following steps a to d.

Step a, determining a second comparison result and a first comparison result of each access authentication key set in the access authentication key set corresponding to the target access right combination.

And b, calculating the queue continuity weight of each verification key queue in the access verification key set corresponding to the target access right combination based on the second comparison result and the first comparison result.

(1) And acquiring biological characteristic updating data from the first biological characteristic recognition result according to the target information authority distribution.

(2) Performing feature fusion on the biological feature updating data to obtain global biological feature data; the feature recognition degree of each feature data in the global biological feature data is a first feature recognition degree or a second feature recognition degree, and the feature data corresponding to all the first feature recognition degrees are dynamic feature data of the global biological feature data.

(3) And determining an information authority list matched with the dynamic characteristic data from the first biological characteristic recognition result.

(4) And determining an information authority matching result of the payment terminal to be detected according to the information authority list.

In step (1), the acquiring, according to the target information authority distribution, biometric update data from the first biometric identification result includes: determining biological feature description information according to the feature dimension division record of the second biological feature recognition result and the feature dimension division record of the first biological feature recognition result; and acquiring biological feature updating data from the first biological feature recognition result according to the biological feature description information and the target information authority distribution.

By the design, based on the content described in the steps (1) to (4), the information authority list can be determined in real time based on the biological feature updating data, so that the determined information authority matching result of the payment terminal to be detected has better timeliness.

In another alternative embodiment, the step S31 of obtaining the first biometric result and the second biometric result for the payment terminal to be detected may include the following steps S311 to S314.

Step S312, determining whether the log format in the current thread running log is changed relative to the log format in the previous thread running log of the current thread running log.

Step S313, if yes, determining the biological characteristic log event positioned from the current thread running log as an effective biological characteristic log event of the current thread running log; otherwise, fusing the biological characteristic log event positioned in the current thread running log with the effective biological characteristic log event at the corresponding position in the previous thread running log to obtain a fusion result, and determining the fusion result as the effective biological characteristic log event of the current thread running log.

Step S314, obtaining the first biometric identification result and the second biometric identification result according to different information extraction paths based on the valid biometric log event of the current thread running log.

In this manner, by applying the above-described steps S311 to S314, the validity of the biometric features between the different acquired biometric feature recognition results can be ensured.
