[0044] like Figure 1-4 As shown, the background transaction method for realizing malicious transaction tracking based on blockchain technology includes the following steps:

[0045] S1. All persons involved in the transaction need to authenticate their personal information through the transaction personnel authentication module 1, and the personal information of the transaction personnel is stored in the blockchain database module 5 through the information storage module 4.

[0051] Working principle: When using the background transaction system and method based on blockchain technology to track malicious transactions, first, before the transaction, all persons participating in the transaction need to authenticate their personal information through the transaction personnel authentication module 1, and store the personal information of the transaction personnel in the blockchain database module 5 through the information storage module 4. After the personal information authentication is passed, the transaction is confirmed by the transaction confirmation module 2, which means the transaction starts. During the transaction, the transaction behavior is monitored in real time through the transaction process monitoring module 3, and the monitoring data is also stored in the blockchain database module 5 through the information storage module 4; secondly, the violation storage module 18 can store operations defined as violations. When the transaction process monitoring module 3 monitors the behavior in the violation storage module 18, the violation screening module 10 can screen the violation during the transaction monitoring process, and then the violation judgment module 19 can confirm whether the behavior is a violation. When a violation occurs for the first time, a warning is given through the violation warning module 11, and at the same time, the transaction The easy-to-interrupt module 12 interrupts the transaction process, and the interruption timing module 13 times the interruption time. After the timing ends, the transaction is resumed by the transaction recovery module 14; then, when the violation occurs again, the alarm module 15 is used to process the alarm, and the transaction termination module 16 terminates the transaction, which improves the security of the transaction and reduces the incidence of malicious transactions; finally, the data in the blockchain database module 5 is regularized by the data regularization module 17, and the data is sorted into relative types of transaction events within a relative time by the time regularization module and the type regularization module, so as to facilitate the subsequent screening and extraction of data, and the transaction is tracked by the transaction tracking module 6, and then the qualified transaction records are screened out from the blockchain database module 5 by the data screening module 7, and the screened transaction records are extracted by the data extraction module 8, and then the corresponding transaction records are locked and continuously tracked by the locking and tracking module 9. This is the working principle of the background transaction system and method for malicious transaction tracking based on blockchain technology.
