Description
Technical Field
The invention belongs to the field of block chains, and particularly relates to a transaction data supervision method.
Background
With the development of informatization and digital currency, more and more businesses and individuals make purchases of goods and delivery of orders through online transactions. When a transaction is generated, private data such as bank account information, identity information and the like of two transaction parties are inevitably acquired by a transaction platform, the information is lost, falsified, leaked and the like, and the private data of a user is easy to be an attack target of a hacker after the scale of the transaction platform becomes large.
The block chain has the technical characteristics of decentralization, openness, anonymity, safety, non-falsification and the like, can ensure the privacy of both users when applied to a transaction platform, can reduce the trust cost among different participants, and improves the working efficiency.
For these trading platforms, it is also necessary for government regulatory authorities to monitor the trading content, and to perform processes such as responsibility tracing and recall in the first time when the quality problem or related disputes occur in the commodities. However, the contradiction between the requirement of high information disclosure by government regulation and the requirement of privacy protection by enterprises is very severe, and how to ensure that the government can not only ensure that transactions are normal, but also protect the privacy of the enterprises is a great problem.

The transaction data supervision method provided by the invention can also have the technical characteristics that the method comprises the following steps: and when the transaction credibility weight is not higher than a preset threshold value, generating corresponding warning information to the receiving party based on the historical transaction contract of the initiator and the corresponding transaction failure identification so as to remind the receiving party that the transaction request has credible risk.
The transaction data supervision method provided by the invention can also have the technical characteristics that the transaction data is stored in the database under the chain and can only be accessed by the initiator and the receiver.
The invention also provides a computer-readable storage medium, which stores a computer program, wherein the computer program, when executed by a processor, implements the transaction data monitoring method as described above.
The present invention also provides a computer device comprising: a memory and a processor; the memory has stored thereon a computer program executable by the processor; when the processor runs the computer program, the transaction data supervision method is executed.
Action and Effect of the invention
According to the medical information transaction data supervision method, the readable medium and the computer equipment, when a transaction request is obtained, the initiator can be verified according to the transaction credibility weight of the initiator, a corresponding transaction contract is generated when the initiator is verified to be credible and the two parties agree, and the transaction contract is further subjected to multi-party encryption through the keys of the initiator, the receiver and the supervisor. Meanwhile, when the transaction is carried out between the receiver and the initiator and the transaction data is generated, whether the transaction data is legal or not can be automatically judged according to the transaction contract, and further, when the transaction data is judged to be legal, the transaction data is directly stored into a linked database, so that the transaction data actually generated by the two parties of the transaction can not be leaked, and the privacy of the two parties can be protected.

Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the effects of the invention easy to understand, the transaction data supervision method, the storage medium and the computer equipment of the invention are specifically described below with reference to the embodiments and the drawings.
< example >
FIG. 1 is a flow chart of a transaction data monitoring method in an embodiment of the invention.
As shown in fig. 1, the transaction data monitoring method specifically includes the following steps S1 to S4.
Step S1, a transaction request initiated by the user node as the initiator to the user node as the receiver is obtained.
In this embodiment, the holders of the user nodes may be various enterprises, organizations, or individuals.
And step S2, verifying whether the transaction credibility weight of the initiator is higher than a preset threshold, and entering step S3 when the transaction credibility weight is higher than the preset threshold, and entering step S4 when the transaction credibility weight is not higher than the preset threshold.
Each user node has a corresponding transaction confidence weight, and the transaction confidence weight is adjusted to be reduced when the user loses confidence (namely, the agreed contract is not finished). In this embodiment, the transaction confidence weight has a value range of 0 to 1, and the predetermined threshold value is 0.7.
Step S3, generating corresponding trade contract according to the trade request after the receiver agrees, and storing the contract on the block chain after multi-party encryption based on the key of the initiator, the receiver and the supervisor, and then entering step S5.
In step S3 of this embodiment, the keys of the initiator, the receiver, and the administrator are calculated to obtain an encryption key through multi-party security calculation, and the transaction contract is encrypted based on the encryption key.
Step S4, based on the historical transaction contract of the initiator and the corresponding transaction failure identification, generating corresponding warning information to the receiver so as to remind the receiver that the transaction request has credible risk, and then entering step S3.
In this embodiment, the warning information includes the transaction confidence weight of the initiator and the bad transaction record, so that the receiver determines whether to receive the transaction request lifted by the initiator according to the information, and if the initiator receives the transaction request, the process proceeds to step S3 to generate the contract.
In addition, in this embodiment, the monitoring party can obtain the corresponding encryption key through the multiparty security calculation again according to the key in the trusted execution environment, and further decrypt and access the transaction contract, thereby implementing the monitoring of the transaction contract.
And step S5, when the transaction data submitted by the initiator or the receiver is received, verifying the transaction data according to the transaction contract, and when the transaction data is verified to be legal, entering step S6, and when the transaction data is verified to be illegal, entering step S7.
And step S6, adding a trade completion identifier for the corresponding trade contract.
In this embodiment, the supervisor may also screen the transaction contract according to the transaction completion identifier and the transaction failure identifier.
In addition, after adding the transaction completion identifier to the transaction contract, the corresponding transaction data may be stored in the linked database, and these transaction data can only be accessed by the initiator and the receiver.
And step S7, sending the transaction data to the supervisor for secondary verification, and entering step S8 when the supervisor verifies that the transaction data is illegal, and entering step S6 when the verification is legal.
And step S8, adding a transaction failure identifier for the corresponding transaction contract, and reducing the transaction credibility weight of the initiator or the receiver initiating the transaction data.
The above explains the specific content of the transaction data supervision method provided by the embodiment. In other aspects of the invention, the above-described method may also be configured as a corresponding computer program and stored in a memory of a computer device. When the processor of the computer device runs the computer program, the transaction data monitoring method of the embodiment can be executed.
In addition, the embodiment also provides a computer storage medium, where the computer storage medium stores computer-executable instructions, and the computer-executable instructions are used to enable a computer to execute the transaction data supervision method provided by the embodiment of the invention.
Examples effects and effects
