With the development of science and technology, various operation data generated by operation are recorded by each enterprise through electronic equipment so that the enterprises can manage the operation process. The credit data of the cooperative enterprise is one of the more important operation data, and can provide basic data for the enterprise to make a partner decision.
Each enterprise records credit data of already collaborating enterprises, such as: the stability of products, the reliability of products and the like are provided, but the credit data obtained by a single enterprise is relatively single, and other credit data of cooperative enterprises need to be obtained from other enterprises. Credit data exchange between enterprises is generally performed as follows: enterprise a needs to obtain the credit data of enterprise C from enterprise B, enterprise a sends a data request to the electronic device of enterprise B through the electronic device, and the electronic device of enterprise B retrieves the credit data of enterprise C from the database according to the data request and sends the credit data to the electronic device of enterprise a.
However, there is a phenomenon that the credit data is tampered by the enterprise B in the above credit data exchange process, so that the enterprise a cannot accurately obtain the credit data of the enterprise C.

When data exchange occurs between any two devices in the exchange system, an exchange record is stored in the blockchain. In addition, any device in the switching system can upload the latest credit data to the block chain to realize real-time update of the block chain, and the credit data can be uploaded only after multi-party verification when being uploaded to the block chain, so that the reliability of the block chain is ensured. In addition, the block chain is stored in an encryption mode, so that the block chain is guaranteed against being stolen or tampered, and the reliability of the block chain is guaranteed.
The responding device 101 acts as a participant in the data exchange, requesting the device 102 to act as an initiator in the data exchange. The authentication device acts as an authenticator for the credit data. An exchange request is sent by requesting device 102 to responding device 101, and responding device 101 parses the credit data from the exchange request and looks up the credit data from the database. After finding the credit data, the responder device 101 determines whether the credit data is verified, and if the credit data is verified, the responder device sends the credit data to the requester device 102.

The responding device, after determining the credit information, looks up the credit data from a locally stored database. After the credit data is found, whether the credit data meets the exchange condition is judged. I.e. to determine whether the authenticity of the credit data has been verified.
And S403, the responding device sends the credit data to the requesting device when the credit data meets the exchange condition.
Wherein the credit data is sent by the responding device to the requesting device if the credit data has been validated, i.e. the credit data is authentic. In addition, verification data may be added to the credit data to indicate the authenticity of the credit data.
S404, the response equipment carries out verification processing on the credit data when the judgment result is negative, and a final verification result is obtained.
If the credit data is not verified, that is, the credit data is unreliable, the responding device needs to verify the reliability of the credit data to obtain a final verification result. If the final verification result shows that the verification is passed, the credit data can be continuously sent to the request equipment, and the credit data exchange between the request equipment and the credit data exchange is realized. If the final verification result indicates that the verification is not passed, the credit data exchange cannot be performed in the requesting device.

s501, the request device sends an exchange request to the response device.
S502, the response equipment judges that the credit data stored in the database meets the exchange condition.
S503, when the response device judges that the credit data stored in the database meets the exchange condition, the response device sends the credit data to the request device.
Steps S401 to S403 are the same as steps S201 to S203 in the embodiment shown in fig. 4, and are not repeated here.
S504, the response device sends the credit data to at least one verification device when the judgment result is negative.
If the credit data is not verified, the credit data is sent to the verification device for verification, that is, the reliability of the credit data needs to be verified by at least one verification device.
And S505, the verification equipment verifies the credit data to generate an intermediate verification result.
The verifying device verifies the reliability of the credit data sent by the response device according to the locally stored credit data and generates a corresponding intermediate verifying result.
The intermediate verification result includes verification pass and verification fail. And when the verification device determines that the credit data sent by the response device is unreliable according to the locally stored credit data, generating an intermediate verification result that the verification is not passed. And when the verification device determines that the credit data sent by the response device is reliable according to the locally stored credit data, generating an intermediate verification result of passing the verification.
S506, the response device receives the intermediate verification result of the credit data returned by the at least one verification device.
After the verification equipment generates the intermediate verification result of the credit data, the intermediate verification result is sent to the response equipment, and the response equipment determines the final verification result of the credit data according to at least one intermediate verification result.
S507, the response equipment determines the final verification result of the credit data according to at least one intermediate verification result.
Wherein after the response device receives at least one intermediate verification result, a final verification result is obtained by statistically analyzing the intermediate verification result credit data.
Obtaining a final verification result by statistically analyzing the intermediate verification result, which specifically comprises: and judging whether the number of the intermediate verification results which show that the verification is passed reaches a preset number. If the judgment result is yes, generating a final verification result which shows that the verification is passed. And if the judgment result is negative, generating a final verification result indicating that the verification fails.
Preferably, after the number of intermediate verification results indicating verification pass exceeds half, a final verification result indicating verification pass is generated. And if the number of the intermediate verification results which represent verification passing is less than half, generating a final verification result which represents verification passing.
And S508, when the final verification result shows that the verification is passed, the response equipment stores the credit data into the block chain to generate an updated block chain.
When the final verification result of the credit data indicates that the verification is passed, the credit data is stored in the block chain to generate an updated block chain, the data in the block chain are verified by the response device, the block chain can be directly transmitted between the response device and the request device in the switching network, and the block chain with high reliability can be obtained.

As shown in fig. 6, another embodiment of the present application provides a credit data exchange method, which is applied to the above exchange system, and the method includes:
s601, the request device sends an exchange request to the response device.
Wherein the exchange request comprises description data of the credit data and the first summary data. The first summary data is used to describe the exchange data provided by the requesting device for exchanging credit data with the responding device. The exchanged data may also be credit data reflecting the credit rating of the enterprise, or other types of data.
For example: the summary data of the credit data provides stability data of the product for enterprise a in the first quarter and the summary data of the exchange data provides stability data of the product for enterprise B in the first quarter.
S602, the response device judges that the first summary data meets the first requirement condition.
The first requirement condition is whether the first summary data is the current requirement data. The method for judging whether the first summary data meets the first requirement condition by the response device specifically includes: and matching the first summary data with the current demand data, and determining that the first summary data meets the first demand condition if the matching is successful.
For example: when the current demand data provides stability data of products for enterprise B, the exchange data provides stability data of the products for enterprise B in the first quarter, the exchange data belongs to the stability data of the products provided by enterprise B, the stability data and the stability data can be matched, and then the first summary data meets the first demand condition.
S603, when the response equipment judges that the first summary data meets the first requirement condition, the response equipment continuously judges that the credit data stored in the preset database meets the exchange condition.
Here, this step has already been described in detail in S402, and is not described here again.
And S604, when the response equipment judges that the credit data stored in the preset database meets the exchange condition, sending second summary data of the credit data to the request equipment.
Wherein, when it is determined that the reliability of the credit data has been verified, second summary data of the credit data is transmitted to the requesting device, and the requesting device may determine whether the credit data satisfies the requirement condition based on the second summary data.
S605, the request device judges that the second summary data meets the second requirement condition.
The second requirement condition is whether the second summary data is the current requirement data. The requesting device determines whether the second summary data meets a second requirement, and specifically includes: and matching the second summary data with the current demand data, and determining that the second summary data meets a second demand condition if the matching is successful.
For example: when the current demand data provides stability data of the product for the enterprise A, the credit data returned by the response equipment provides the stability data of the product for the enterprise A, and the credit data and the stability data can be matched, so that the second summary data meets a second demand condition.
And S606, the request device sends the exchange data when judging that the second summary data meets the second requirement condition.
When the request equipment judges that the second summary data sent by the response equipment meet the requirements, the request equipment agrees to carry out data exchange with the response equipment, and complete data of the data are exchanged to the response equipment.
S607, the response device sends credit data to the request device.
After receiving the exchange data sent by the requesting device, the responding device also sends credit data to the requesting device, and completes data exchange.
And S608, the response device forwards the exchange request to at least one verification device when judging that the first summary data does not meet the first requirement condition.
When the response device does not exchange data with the request device, the response device forwards an exchange request to the verification device, and at this time, the verification device serves as a participant of data exchange, and can continue to execute the credit data exchange method executed by the response device.
And S609, the response equipment forwards the exchange request to at least one verification equipment when the credit data is judged to meet the exchange condition.
After the response device exchanges data with the request device, the response device forwards an exchange request to the verification device, and at this time, the verification device serves as a participant of data exchange, and can continue to execute the credit data exchange method executed by the response device. That is, the requesting device may receive credit data returned by multiple devices.
S610, the response device generates record data for representing data exchange.
The response device records the data exchange process between the response device and the request device, records the data exchange process between the response device and the verification device, and generates corresponding record data.
S611, the response equipment stores the recorded data into the block chain and generates an updated block chain.
After the response equipment generates the record data, the record data is stored into the block chain to generate an updated block chain.
In the credit data exchange method provided by the embodiment of the application, the data requiring party sends the required data and the summary data of the exchanged data to other participating parties, when the participating parties judge that the exchanged data meets the requirements and the demanders judge that the data sent by the participating parties meet the requirements, the two parties exchange data, and otherwise, the exchange fails. And the whole exchange process is recorded on the chain, and the data source and the data destination are also recorded on the chain for tracing.
