Step S110 is to obtain a processing instruction of the payment verification request generated according to the payment verification environment information sent by the blockchain node, and obtain corresponding request processing information after processing the payment verification request according to the processing instruction.

Step S120, obtaining the verification environment update element sequence according to the payment verification environment update information of the payment terminal device corresponding to the request processing information for the request processing information.

Step S130, according to the label transfer parameter and the updating change parameter of the updating element of the verification environment, obtaining verification parameter service information, and performing fast Fourier transform on the field parameter of the verification parameter field in the verification parameter service information to obtain a field marking value sequence corresponding to the verification parameter field.

Step S140, the transaction voucher label transfer parameter corresponding to the verification parameter field in the verification parameter service information is reversely converted to obtain the voucher service label transfer parameter corresponding to the verification parameter field, and a request processing updating process is generated according to the voucher service label transfer parameter and the field marking value sequence, so that the corresponding payment verification request generated by the payment verification environment information is continuously processed based on the request processing updating process.

In this embodiment, the request processing information may be used to indicate a processing reason corresponding to the current request processing, for example, when the payment verification request is intercepted, may be used to indicate a reason of the current interception, for example, a reason of intercepting a certain failed verification environment element.

In this embodiment, when the payment terminal device obtains the request processing information, the user may be prompted to switch the current payment verification environment, so as to change to a payment verification environment with higher security, and in this process, the payment terminal device generates a payment verification environment update after the switching, so as to obtain a verification environment update element sequence, where each verification environment update element in the verification environment update element sequence includes an update change parameter of the verification environment update element and a tag transfer parameter for describing a verification tag to which the verification environment update element belongs. For example, the update change parameter may be used to indicate a configuration parameter of the verification environment update element after the update change, and the tag transition parameter may be used to indicate a configuration parameter of the verification tag to which the verification environment update element belongs after the transition.

In this embodiment, the transaction certificate label transfer parameter may be used to indicate a transfer parameter of a security certificate for verification of parameters related to the transaction certificate in a label transfer process, a field parameter of a verification parameter field in the verification parameter service information may be used to indicate an arrangement condition of field parameters in a payment verification process, and thus, after performing fast fourier transform, a field indication value sequence corresponding to the verification parameter field may be obtained.

Based on the above design, after the verification parameter service information is generated according to the label transfer parameter and the update change parameter of the verification environment update element, mapping field parameters of an authentication parameter field in the authentication parameter service information into a field designation value sequence, and the transaction voucher label transfer parameter is inversely converted into a voucher service label transfer parameter, a request processing updating process is generated by combining the voucher service label transfer parameter and the field marking value sequence, the follow-up request processing updating verification operation is carried out by considering that the payment voucher service is suitable for the label transfer process after the payment verification scene is updated and the field marking value sequence related to the verification parameter service information, thereby being convenient for flexibly adapting to the last payment verification environment when the payment verification environment changes, and further improve the scene practicality of mobile payment when improving the security of mobile payment.

In one possible implementation, for step S110, in order to effectively improve the security of mobile payment under various payment verification environments, the following exemplary sub-steps may be implemented, which are described in detail below.

And step S111, acquiring at least one verification element sequence from the payment verification environment information sent by the block nodes.

In this embodiment, each verification element object in each verification element sequence belongs to the same verification tag, and each verification element object corresponds to a tag configuration parameter under the verification tag to which it belongs. For example, it is possible to acquire authentication element objects of which authentication tags belong to the same authentication tag from the payment authentication environment information transmitted from the block node, and determine the authentication element object belonging to each authentication tag as a corresponding authentication element sequence.

For example, when the blockchain node performs verification of the payment request, it needs to upload payment verification environment information to the big data platform first, where the payment verification environment information may include a plurality of verification element objects, each verification element object may refer to a related security environment field that needs to complete verification, and these security environment fields may be used to represent different environment attributes in the payment verification environment. Similarly, for different verification element objects, the types of the corresponding security environment fields are different, and therefore, the verification element objects may correspond to a certain verification tag one to one, that is, the verification tag may be used to represent the types of the security environment fields.

In this embodiment, the verification threat attribute may be used to indicate an attribute field that may have a verification threat capability, the verification threat attribute feature may be used to indicate a field feature sequence corresponding to the verification threat attribute, and the corresponding threat attribute confidence may be used to indicate a degree that the field feature sequence corresponding to the verification threat attribute has the verification threat capability.

In this embodiment, the attack tracking parameter may be used to represent tracking process information of a security verification attack behavior that may be generated, so that an attack path graphical object corresponding to each verification tag may be determined according to the attack tracking parameter of the verification tag to which each verification element object corresponds, and the attack path graphical objects are used to represent key content in the attack tracking process, so as to generate a processing instruction of the payment verification request corresponding to the payment verification environment information according to the attack path graphical object corresponding to each verification tag.

Based on the design, the verification threat attribute characteristics of each verification element sequence are extracted in a verification threat attribute mining mode, and the attack tracking parameters of the verification tags corresponding to the verification element objects are determined based on the threat attribute confidence, so that the configuration parameters of the tags are converted into effective payment security identification bases. Therefore, according to the attack tracking parameters of the verification tags corresponding to the verification element objects, the attack path graphical object corresponding to each verification tag is determined, and the processing instruction of the payment verification request corresponding to the payment verification environment information is generated according to the attack path graphical object corresponding to each verification tag, so that the response strategy for each payment verification request is determined, and the mobile payment safety under various payment verification environments is effectively improved.

In one possible implementation, step S112 may be implemented by the following exemplary sub-steps, which are described in detail below.

In the sub-step S1121, for each verification element sequence, traversing the verification element object in the verification element sequence, extracting the verification element content comparing the configuration parameters of each tag under the verification tag to which the verification element sequence belongs from the verification element object, and determining the content related data corresponding to the verification element sequence according to the extracted verification element content.

In the substep S1122, set content features included in the content of each verification element in the content-related data are removed, content nodes of the content of the verification element with the removed set content features are split to obtain first content-related data, and the confidence of each content node is determined according to the number of existing lines of the content nodes in the content of the verification element included in the first content-related data.

And a substep S1123 of removing content nodes with the confidence degree smaller than a preset confidence degree threshold value in the first content related data to obtain second content related data, taking the content nodes with the confidence degree not smaller than the preset confidence degree threshold value as pre-content nodes to obtain a pre-content node sequence, and determining a post-content node sequence which corresponds to each pre-content node and consists of content nodes connected behind the pre-content node according to the occurrence condition of each pre-content node in the pre-content node sequence in the second content related data.

And a substep S1124 of determining whether the post content node sequence is empty, recursively returning if the post content node sequence is empty, and counting the confidence level of each content node in the post content node sequence if the post content node sequence is not empty, and determining whether the confidence level of each content node meets the minimum confidence level requirement.

And in the substep S1125, if the confidence level of the content node does not meet the requirement of the minimum confidence level, recursively returning, if the confidence level of the content node meets the requirement of the minimum confidence level, merging the content node and a preposed content node corresponding to the postposed content node sequence to obtain a new preposed content node, determining the postposed content node sequence of the new preposed content node, and performing recursive mining on the postposed content node sequence corresponding to the new preposed content node to obtain all target preposed content nodes meeting the requirement of the minimum confidence level and corresponding confidence levels.

For example, the recursively returned data is all currently obtained target pre-content nodes meeting the minimum confidence requirement and corresponding confidences, all target pre-content nodes meeting the minimum confidence requirement and corresponding confidences are obtained, the target pre-content nodes are used as verification threat attribute features of the verification element sequence, and the confidences of the target pre-content nodes in the post-content node sequence are used as threat attribute confidences corresponding to the verification threat attribute features.

In a possible implementation manner, for step S113, in order to accurately and comprehensively determine an editable object having a tampering behavior, thereby improving the coverage rate and accuracy of detecting the tampering behavior, and effectively determining an attack tracking parameter of the authentication tag to which each of the authentication element objects corresponds, the following exemplary sub-steps may be implemented. The detailed description is as follows.

And a substep S1131, screening candidate verification threat attribute features larger than a preset threat attribute confidence degree from the verification threat attribute features according to the verification threat attribute features and the corresponding threat attribute confidence degrees, so as to obtain candidate verification threat attribute features.

And a sub-step S1132, obtaining a first tampering suspected behavior list corresponding to the first attribute feature node and a second tampering suspected behavior list corresponding to the second attribute feature node on the candidate verification threat attribute feature.

For example, the first list of tampering suspected behaviors includes a plurality of change behaviors of the first attribute feature node to change the associated command line in the candidate verification threat attribute feature, the second list of tampering suspected behaviors includes a plurality of change behaviors of the second attribute feature node to change the associated command line in the candidate verification threat attribute feature, and each change behavior includes a plurality of change behavior flow nodes.

And a substep S1133, based on the preset change behavior category, clustering the multiple change behaviors in the first tampering suspected behavior list to obtain a clustered first tampering suspected behavior list. The preset change behavior category belongs to types corresponding to the plurality of change behavior flow nodes.

In the substep S1134, the modified behavior process nodes corresponding to each preset modified behavior category in the preset modified behavior category sequence in the clustered first tampered suspected behavior list are combined into a first initial modified behavior sequence.

And a substep S1135, performing deduplication on the first initial modified behavior sequence to obtain a first modified behavior sequence, thereby obtaining a first modified behavior sequence corresponding to a preset modified behavior category sequence, and combining each modified behavior flow node in the first modified behavior sequence into a first modified behavior flow node sequence corresponding to the first attribute feature node.

For example, the first modified behavior flow node sequence corresponds to a preset modified behavior category sequence, and the preset modified behavior category type is a sequence formed by various modified behavior categories for tamper behavior detection.
