In addition, when the blockchain payment node carries out payment, a period of vacuum period of the equipment interface exists, and the interface access authority of the blockchain payment node is opened in the vacuum period of the equipment interface, so that a multiplier is provided for the invasion of third-party equipment.
It follows that in order to improve the above technical problem, the following two problems need to be solved:
(1) the detection of the payment network environment of the whole block chain network is realized;
(2) interface access rights of the blockchain payment node during the vacuum period are modified.
In view of this, embodiments of the present invention provide a method for detecting a payment network environment applied to blockchain payment and a network server, which can detect a payment network environment of an entire blockchain network and modify an interface access right of a blockchain payment node in a vacuum period, so as to prevent the blockchain payment node from being invaded by a third-party device when performing a blockchain payment action.
To better illustrate the technical solution, please first refer to fig. 1, which shows a system architecture diagram of a payment network environment detection system 100 applied to blockchain payment, where the payment network environment detection system 100 may include a network server 200 and a plurality of blockchain node devices 400. Wherein the blockchain node devices 400 communicate with each other to form a blockchain network, and the network server 200 communicates with the blockchain network to detect a payment network environment of the blockchain network and to instruct the blockchain node devices to modify the interface access rights. In the present embodiment, the block link point device 400 may be an intelligent electronic device having communication and mobile payment functions, such as a portable terminal. The web server 200 may be a server deployed in the cloud.
Further, on the basis of fig. 1, fig. 2 shows a flowchart of a payment network environment detection method applied to blockchain payment, which may be applied to the network server 200 in fig. 1, and specifically may include the contents described in the following steps S210 to S250.
Step S210, after obtaining the authorization of the first block link point device, obtaining a historical payment record corresponding to the first block link point device.
For example, the network server may issue an access request to the first blocklink point device in advance to obtain authorization of the first blocklink point device.
Step S220, after obtaining the authorization of the second block link point device having valid transaction behavior with the first block link point, classifying the plurality of payment lists in the historical payment record based on the historical collection record of the second block link point device, so as to obtain a plurality of valid payment lists and a plurality of invalid payment lists.
For example, the historical payment record may be retrieved from the second block node device, the time period of the historical payment record may be adjusted according to actual conditions, and the valid payment list indicates that the current payment behavior is valid, and the invalid payment list indicates that the current payment behavior is invalid.
Step S230, determining payment request rejection information corresponding to each invalid payment list and payment behavior data of the first block chain node device, based on the acquired network state data of the block chain network in which the first block chain node device and the second block chain node device are located in the current time period.
For example, the invalid payment manifest is in a one-to-one correspondence with the payment request rejection information.
Step S240, determining payment environment index data of the blockchain network based on at least the payment request rejection information, the historical collection records, and the network status data.
For example, the payment environment metric data is used to characterize the payment environment security of the blockchain network.

Therefore, the detection of the payment network environment of the whole block chain network and the modification of the interface access authority of the first block chain node device in the vacuum period can be realized, and the first block chain node device is prevented from being invaded by a third-party device when the block chain payment action is executed.
In practical application, the inventor finds that incomplete payment environment index data often occurs when determining the payment environment index data of the blockchain network, and innovatively finds that the time sequence difference condition of blockchain payment and blockchain transaction at different equipment ends is not considered. To improve this problem and ensure the integrity of the payment environment index data, the determination of the payment environment index data of the blockchain network based on at least the payment request rejection information, the historical collection record and the network status data, which is described in step S240, may specifically include the following descriptions in step S241 to step S244.

Step S243, calculating time sequence asynchronous data between the transaction prompt information and the payment risk prompt information based on the network state data and determining payment delay data of the block chain network according to the time sequence asynchronous data; the time sequence asynchronous data are used for representing the difference between the generation time of the transaction prompt message and the generation time of the payment risk prompt message.
Step S244, determining data distribution characteristics of the payment delay data in the network status data, weighting the data distribution characteristics by using a ratio of the valid payment list to the invalid payment list to obtain weighted distribution characteristics, and determining payment environment index data of the block chain network based on the weighted distribution characteristics.
In this way, by applying the above steps S241 to S244, the timing difference between the blockchain payment and the blockchain transaction at different device ends can be considered, so as to ensure the integrity of the determined payment environment index data.
In an implementation manner, in order to implement accurate and reliable modification of the interface access right of the first block-link point device to ensure information security of the first block-link point device, the modification of the interface access right of the first block-link point device according to the payment environment index data and the input instruction received by the first block-link point device to instruct the first block-link point device to perform block chain payment transaction, which is described in step S250, may further include what is described in the following steps S251 to S254.

Step S253, inquiring a current communication address of the transaction side equipment corresponding to the equipment identification information in a preset database, requesting equipment access authorization of the transaction side equipment based on the current communication address, generating an inquiry request for inquiring the equipment running state of the transaction side equipment according to the expected transaction time period and the expected transaction duration after obtaining the equipment access authorization of the transaction side equipment, and sending the inquiry request to the transaction side equipment to obtain target running state information returned by the transaction side equipment based on the inquiry request; wherein the target operational state information matches the expected transaction period and the expected transaction duration.
Step S254, determining an equipment interface vacuum period for which the first block link point equipment matches the expected transaction period and the expected transaction duration based on the equipment operating state; judging interface intrusion probability corresponding to the payment environment safety factor and interface permission information corresponding to the interface intrusion probability in the equipment interface vacuum period; and modifying the interface access authority of the first block chain node point equipment when the interface intrusion probability is greater than the set probability.
In the implementation process, when the contents described in steps S251 to S254 are executed, the interface access right of the first block-link-point device can be accurately and reliably modified, so as to ensure the information security of the first block-link-point device.
