The specific process is as follows; Data definition: define the real-time data of seeds in the customs intelligent seed cabinet, define a unified data model and metadata, including data structure, data type, and data format; Data mapping: Map the real-time data of seeds in the customs intelligent seed cabinet, determine the data mapping relationship between the real-time data of seeds in the customs intelligent seed cabinet, and make the data consistent; Data rules: formulate data rules and constraints based on the real-time data of seeds in the customs intelligent seed cabinet, specify the legal scope of data, define the constraints of data, automatically review the real-time data of seeds in the customs intelligent seed cabinet, and determine whether it complies with regulations; Data testing: Test the real-time seed data of the customs smart seed cabinet after consensus is reached, check the consistency and accuracy of the data, and make adjustments or storage based on the test results.

[0031] In this embodiment, as a preferred technical solution of the present invention, the uplink storage module further includes: A data storage unit, used to store the real-time data of seeds in the customs smart seed cabinet on blockchain; Based on the real-time data of seeds in the customs smart seed cabinet, the blockchain node is searched, the real-time data of seeds in the customs smart seed cabinet is encrypted using an encryption algorithm, and the encrypted real-time data of seeds in the customs smart seed cabinet is securely stored on the blockchain node.

[0032] In this embodiment, as a preferred technical solution of the present invention, the access control module includes: Data query unit, used to query the real-time data of seeds in the customs intelligent seed cabinet; Through smart contracts or API interfaces, the customs department initiates data query requests to the blockchain network; Access verification unit, used to verify access rights of customs authorities; After the blockchain network receives the data query request sent by the customs department, it verifies the access rights of the customs department.

[0033] In this embodiment, as the preferred technical solution of the present invention, the blockchain network verifies the access rights of the customs department and performs the following operations: Obtain the data query access port of the customs department; Based on the pre-set data query access ports of the blockchain network, a comparative analysis of the data query access ports of the customs department is conducted; Among them, the data query access port of the customs department is compared one by one with the multiple data query access ports pre-set by the blockchain network to determine whether the data query access port of the customs department is within the range of the multiple data query access ports pre-set by the blockchain network; When the customs department's data query access port is within the range of multiple data query access ports pre-set by the blockchain network, the customs department has the authority to access blockchain data; When the customs department’s data query access port is not within the range of multiple data query access ports pre-set by the blockchain network, the customs department does not have the authority to access the blockchain data; After the customs department's access rights are verified, the customs department can access the data only if the verification is qualified.

[0034] Therefore, through smart contracts or API interfaces, the customs department initiates a data query request to the blockchain network. The blockchain network verifies the access rights of the customs department. After the verification is qualified, the data query request will be routed to the corresponding blockchain node. After receiving the data query request, the blockchain node obtains the encrypted customs smart seed cabinet seed real-time data from the blockchain according to the authority, and decrypts and restores the encrypted customs smart seed cabinet seed real-time data, and returns the decrypted and restored customs smart seed cabinet seed real-time data to the customs department, so that the customs smart seed cabinet seed real-time data can be shared, thereby realizing data sharing on the blockchain.

[0035] Specifically, the access security monitoring of the data query access port is performed in real time, and the following operations are performed: Collect data in real time to query the operating parameters of the access port, wherein the operating parameters include request rate, request processing response time rate, error code ratio and attack blocking rate; The operation abnormality determination coefficient is obtained by using the request rate, request processing response time rate, error code ratio and attack blocking rate included in the operation parameters of the data query access port; The abnormal operation determination coefficient is obtained by the following formula: Where C represents the operation abnormality determination coefficient; n represents the number of unit times contained in the operation time of the data query access port; R i represents the request rate corresponding to the i-th unit time; T pi represents the request processing response time rate corresponding to the i-th unit time; E i A represents the error code ratio corresponding to the i-th unit time; i represents the attack blocking rate corresponding to the i-th unit time; Comparing the operation abnormality determination coefficient with a preset determination coefficient threshold; When the operation abnormality determination coefficient exceeds a preset determination coefficient threshold, the encryption strength of the data query access port is determined, and the security of the data query access port is determined by the encryption strength.

[0036] The technical effect of the above technical solution is: by collecting the operating parameters of the data query access port in real time (such as request rate, request processing response time rate, error code ratio and attack blocking rate), the system can instantly perceive the operating status of the port. This real-time monitoring mechanism helps to quickly identify potential security threats or performance bottlenecks, thereby allowing the system to take countermeasures in time to reduce potential losses. Using the collected operating parameters, the operation abnormality determination coefficient (C) is calculated by a specific formula, which comprehensively reflects the overall operating status of the data query access port. Compared with the monitoring of a single parameter, this method is more comprehensive and accurate, and can more accurately identify the abnormal behavior of the port. By presetting the determination coefficient threshold, the system can flexibly adjust the sensitivity of security monitoring according to actual needs. This helps to balance the security and performance of the system and avoid false positives or negative positives caused by excessive sensitivity. When the operation abnormality determination coefficient exceeds the preset threshold, the system will determine the encryption strength of the data query access port. This mechanism helps to promptly discover and repair the problem of insufficient encryption strength, thereby improving the security of the data query access port. Through real-time monitoring and abnormality determination, the system can promptly discover and optimize performance bottlenecks and improve the operating efficiency of the data query access port. At the same time, this mechanism also helps to reasonably allocate system resources and avoid resource waste and excessive consumption.

[0037] In summary, the technical effects of this technical solution in terms of performance indicators are mainly reflected in real-time monitoring and response, accurate operation abnormality judgment, flexible judgment threshold setting, encryption strength judgment and security improvement, performance optimization and resource utilization, etc. These effects jointly improve the security and operation efficiency of the data query access port.

[0038] Specifically, when the operation abnormality determination coefficient exceeds a preset determination coefficient threshold, the encryption strength of the data query access port is determined, and the security of the data query access port is determined by the encryption strength, and the following operations are performed: When the operation abnormality determination coefficient exceeds a preset determination coefficient threshold, the encrypted transmission times of the data query access port are retrieved; Extract the attack frequency and bandwidth utilization corresponding to each encrypted transmission number; The encryption transmission safety factor is obtained by using the attack frequency and bandwidth utilization corresponding to each encrypted transmission number in combination with the operation abnormality determination coefficient; The encryption transmission security factor is obtained by the following formula: Among them, S represents the encryption transmission security factor; m represents the number of encryption transmissions; f i represents the attack frequency corresponding to the i-th encrypted transmission; P direpresents the bandwidth utilization rate corresponding to the i-th encrypted transmission; C represents the operation abnormality determination coefficient; f b represents the standard deviation of the attack frequency corresponding to m encrypted transmissions; P b It represents the standard deviation of bandwidth utilization corresponding to m encrypted transmissions; Comparing the encrypted transmission security factor with a preset encrypted transmission security factor threshold; When the encryption transmission security factor exceeds a preset encryption transmission security factor threshold, the security of the data query access port is determined to be abnormal, and a security abnormality alarm is issued.

[0039] The technical effect of the above technical solution is: by introducing parameters such as the number of encrypted transmissions, attack frequency and bandwidth utilization, and combining the operation abnormality determination coefficient, the solution can more accurately evaluate the security of the data query access port during the encrypted transmission process. The calculation of the encrypted transmission security coefficient takes into account information from multiple dimensions, making the security determination more comprehensive and accurate. The solution can monitor the operating status of the data query access port in real time, and immediately determine the encryption strength when an abnormality is found. This dynamic monitoring mechanism helps to timely discover potential security threats and respond quickly, thereby reducing security risks. By presetting the encrypted transmission security coefficient threshold, the system can flexibly adjust the sensitivity of security monitoring according to actual needs. This helps to balance the security and performance of the system, avoid false positives or false negatives caused by excessive sensitivity, and ensure that security abnormality alarms can be issued in time when necessary. When the encrypted transmission security coefficient exceeds the preset threshold, the system can determine that the security of the data query access port is abnormal and issue a security abnormality alarm. This mechanism helps to timely discover and repair security vulnerabilities, enhance the security protection capabilities of the system, and protect the security and integrity of data. Through real-time monitoring and accurate security determination, the solution can optimize the utilization of system resources and avoid unnecessary waste of resources. At the same time, this mechanism also helps to improve the operating efficiency of the system and ensure the stability and reliability of the data query access port.

[0040] In summary, the technical effects of this technical solution in terms of performance indicators are mainly reflected in accurate security judgment, dynamic monitoring and response, flexible security threshold setting, enhanced security protection capabilities, and optimized resource utilization. These effects jointly improve the security, stability, and operating efficiency of the data query access port.
