[0026] Please refer to Figure 1 and Figure 2 , Figure 1 This is a flowchart of an implementation method of a blockchain-based data transmission method provided by this application. Figure 2 It is a schematic diagram of the framework structure of an implementation method of the sender and the receiver in this application; the method includes:

[0027] S11: The data exchange platform of the sender extracts the data to be transmitted from the sending business system in the sender's intranet.

[0028] This implementation manner may be executed by a data exchange platform of the sender, and the data exchange platform transmits the data to be transmitted of the sender to the receiver.

[0029] In one embodiment, the data exchange platform may be a software or system, or a collection of multiple systems or software, which can communicate with the sending business system in the sender's intranet to extract the data to be transmitted in the sending business system. The sender's data exchange platform may be deployed in the sender's intranet or in the sender's extranet. The sender's data exchange platform may extract the data to be transmitted from the sending business system in response to the request of the sending business system; the sender's data exchange platform may also actively extract the data to be transmitted from the sending business system in response to user instructions. The data to be transmitted may be the business data generated by the sending business system.

[0030] In a specific embodiment, the data exchange platform of the sender is deployed in the intranet of the sender. The data exchange platform of the sender extracts the data to be transmitted from the sending business system in response to the request of the sending business system. Specifically, the sending business system calls the interface of the data exchange platform of the sender, and transmits the execution JOB parameters to the data exchange platform of the sender through the interface. The data exchange platform of the sender extracts the data to be transmitted from the sending business system based on the execution JOB parameters. The JOB parameters include: the name of the job, the type of the job, the specific action of the job, the start time of the job, the repetition interval of the job, the end time of the job, whether the job is automatically deleted after completion, whether the job is enabled, whether an event is triggered when the job status changes, and the scheduling rules of the job. The JOB parameters can control the execution time, frequency, and input parameters of the job to ensure that the job can be executed according to predetermined rules and conditions. The data to be transmitted can be structured data or unstructured data.

[0031] The sender and the participant may be two organizations or institutions or agencies or units with a certain association relationship, and the association relationship may be an association between organizations or institutions or agencies or units, or an association between businesses. For example, the sender and the participant are in a superior-subordinate relationship, the sender and the participant belong to the same superior organization, the sender and the participant both process the same business, and the business of the sender or the participant depends on the business data of the other party. Understandably, the sender and the participant are different.

[0032] S12: Encode the data to be transmitted to obtain encoded data of the data to be transmitted.

[0033] In one embodiment, the data to be transmitted may be processed to obtain unique coded data of the data to be transmitted. For example, the data to be transmitted may be encoded in any manner such as binary encoding, decimal encoding, ASCII encoding, Unicode encoding, etc. to obtain coded data.

[0034] In a specific implementation, a hash operation may be performed on the data to be transmitted, and the obtained hash value may be used as the encoding data of the data to be transmitted.

[0035] S13: The data to be transmitted is transmitted to the data exchange platform of the recipient through the gateway, and the encoded data is uploaded to the blockchain.

[0036] In one embodiment, the data exchange platform of the sender transmits the data to be transmitted to the data exchange platform of the receiver through the network gate, and uploads the encoded data to the blockchain. The data exchange platform of the receiver is used to send the data to be transmitted to the receiving business system in the receiver's intranet when the encoded data on the blockchain verifies the data to be transmitted. The step of verifying the data to be transmitted can be performed by the data exchange platform of the receiver or by other nodes in the blockchain. Among them, the sender and the participant can be a participating node in the blockchain or not a participating node in the blockchain.

[0037] It can be understood that in other embodiments, the encoded data can also be uploaded to the blockchain by the sending business system, that is, after the sender's data exchange platform obtains the encoded data, it sends the encoded data to the sending business system, and the sending business system further uploads the encoded data to the blockchain.

[0038] Among them, the network gate is an information security device that uses a solid-state switch read-write medium with multiple control functions and can connect two independent host systems. Since the two independent host systems are isolated by the network gate, there is no physical connection, logical connection, or information transmission protocol for communication between the systems, and there is no information exchange based on the protocol, but only non-protocol ferrying in the form of data files. Therefore, the network gate physically isolates and blocks all network connections that have potential attacks on the intranet, making it impossible for external attackers to directly invade, attack, or destroy the intranet, thus ensuring the security of the internal host.

[0039] In a specific embodiment, Figure 2As shown, the data exchange platform of the sender sends the data to be transmitted to the first network gate via the front-end processor of the sender, and the first network gate sends the data to be transmitted to the data exchange platform of the receiver via the front-end processor of the receiver. In other words, the data to be transmitted first reaches the front-end processor of the sender from the data exchange platform of the sender located at the back end. The front-end processor can be a device or system located at the front end. The front-end processor of the sender sends the data to be transmitted to the front-end processor of the receiver through the first network gate. The front-end processor of the receiver can perform preliminary processing and analysis on the received data, and forward the processed data to the data exchange platform of the receiver located at the back end. Among them, the data exchange platform of the sender and the front-end processor of the sender are both located in the intranet of the sender, and the data exchange platform of the receiver and the front-end processor of the receiver are both located in the intranet of the receiver.

[0040] In the above method, both the sender and the receiver deploy data exchange platforms. The sender's data exchange platform extracts the data to be transmitted from the sending business system in the sender's intranet, encodes the data to be transmitted, and obtains the encoded data of the data to be transmitted; transmits the data to be transmitted to the receiver's data exchange platform through the network gate, and uploads the encoded data to the blockchain; the receiver's data exchange platform is used to send the data to be transmitted to the receiving business system in the receiver's intranet when the encoded data on the blockchain verifies the data to be transmitted. The data of the sending business system is transmitted to the receiving business system through the sender's data exchange platform and the receiver's data exchange platform, so as to realize data transmission between at least two business systems in different intranets. Furthermore, the verification of the data to be transmitted based on the encoded data on the blockchain can ensure the security of the data entering the receiving business system.

[0041] In the above-mentioned implementation manner, the plaintext data of the data to be transmitted is transmitted to the data exchange platform of the recipient through the network gate. In other implementation manners, considering the possibility of leakage of the plaintext data, in order to further improve data security, the data to be transmitted can be encrypted before being transmitted to the data exchange platform of the recipient through the network gate to obtain ciphertext data, and the ciphertext data can be transmitted to the data exchange platform of the recipient through the network gate. It can be understood that in other implementation manners, the encoded data can also be transmitted to the data exchange platform of the recipient. In a specific implementation manner, the data to be transmitted and the encoded data can be encrypted together to obtain ciphertext data. The ciphertext data is transmitted to the data exchange platform of the recipient through the network gate. Among them, the encryption can be performed using the national secret SM2 algorithm with a private key.

[0042] Since the sender and the receiver use different systems, the data formats used by the two may be different. Therefore, in one embodiment, after the data exchange platform of the sender extracts the data to be transmitted from the sending business system in the sender's intranet, it can perform preset processing on the data to be transmitted to obtain the final data to be transmitted; wherein the preset processing includes classification and / or format conversion. Among them, the classification and summary can classify and summarize the data to be transmitted according to the data type and / or the time when the data is generated. It can be understood that in other embodiments, after the data to be transmitted is transmitted to the data exchange platform of the receiver through the network gate, the data exchange platform of the receiver can perform preset processing on the data to be transmitted, and after the data to be transmitted is verified, the preset processed data to be transmitted is sent to the receiving business system in the receiver's intranet.

[0043] In one embodiment, the data exchange platform of the sender can also monitor the entire process of data transmission, for example, monitor the target process, the target process includes at least one of the extraction process and the encoding process, the extraction process is the process in which the data exchange platform of the sender extracts the data to be transmitted from the sending business system in the sender's intranet, and the encoding process is the process of encoding the data to be transmitted and obtaining the encoded data of the data to be transmitted. In response to monitoring the existence of an abnormality in the target process, an operation corresponding to the abnormality is performed; and / or, in response to the number of abnormalities generated in the same target process exceeding a threshold, an early warning is issued. For example, if the extraction process is abnormal more than 3 times, an early warning message can be generated and displayed on the front end to remind the user.

[0044] Wherein, when the target process is an extraction process, monitoring the target process to have an abnormality may include monitoring that the data to be transmitted is not extracted or that erroneous data to be transmitted is extracted. When the target process is an encoding process, monitoring the target process to have an abnormality may include monitoring that the encoded data is not obtained or that the encoded data is incorrect, wherein the encoding data error includes but is not limited to the format of the encoded data being different from the preset format. It can be understood that the above-mentioned monitoring of the target process to have an abnormality is only exemplary, and in other embodiments, it may also be other situations, which can be set by the user according to the specific situation.

[0045] Please refer to Figure 3 and Figure 4 , Figure 3 It is a flowchart of another implementation method of the blockchain-based data transmission method provided by this application. Figure 4 It is a schematic diagram of the framework structure of an implementation method of a sender, an intermediate management party and a receiver in this application. The method includes:

[0046] S31: The data exchange platform of the sender extracts the data to be transmitted from the sending business system in the sender's intranet.

[0047] S32: Encode the data to be transmitted to obtain encoded data of the data to be transmitted.

[0048] Among them, for the specific implementation of steps S31 and S32, please refer to steps S11 and S12 in the first implementation of the blockchain-based data transmission method provided in this application, which will not be repeated here.

[0049] S33: The data to be transmitted is transmitted to the intermediate management party through the network gate, and the data exchange platform of the intermediate management party transmits the data to be transmitted to the data exchange platform of the recipient through the network gate, and uploads the encoded data to the blockchain.

[0050] In one embodiment, in addition to the sender and the receiver, an intermediate management party is also included. The intermediate management party may be the superior of the sender and the receiver, or may be at the same level as the sender or the receiver, or may have a business relationship with the sender or the receiver. In a specific embodiment, taking the example that the intermediate management party may be the superior of the sender and the receiver, the sender may first send the data to be transmitted to the intermediate management party, which may review the data before sending it to the receiver. It can be understood that there may be one or more receivers, and multiple receivers may be selected by the intermediate management party from multiple candidate parties.

[0051] The data exchange platform of the sender transmits the data to be transmitted to the data exchange platform of the intermediate management party through the network gate, and the data exchange platform of the intermediate management party transmits the data to be transmitted to the data exchange platform of the receiver through the network gate. The data exchange platform of the sender can upload the coded data to the blockchain. The data exchange platform of the intermediate management party receives the data to be transmitted, and can encode the received data to be transmitted using the same encoding method, and upload the obtained coded data to the blockchain. It can be understood that the data exchange platform of the intermediate management party can obtain the coded data uploaded by the data exchange platform of the sender from the blockchain and compare it with the coded data obtained by itself. If they are consistent, the received data to be transmitted will be forwarded to the data exchange platform of the receiver.

[0052] The receiving party's data exchange platform can also encode the received data to be transmitted and upload the obtained encoded data to the blockchain. All participants upload the encoded data to the blockchain, and data traceability can also be achieved.

[0053] In one embodiment, the intermediate manager can also serve as a receiver, that is, after the data exchange platform of the intermediate manager receives the data to be transmitted, it determines whether the intermediate manager is the receiver. If so, when the data to be transmitted is verified based on the encoded data on the blockchain, the data to be transmitted is sent to the intermediate business system in the intranet of the intermediate manager.

[0054] In a specific embodiment, Figure 4As shown, the data to be transmitted first reaches the front-end processor of the sender from the data exchange platform of the sender located at the back end, and the front-end processor of the sender sends the data to be transmitted to the first front-end processor of the intermediate management party through the first network gate, and the first front-end processor of the intermediate management party forwards the data to be transmitted to the data exchange platform of the intermediate management party located at the back end, and the data exchange platform of the intermediate management party determines whether it is the receiver, and if not, the data to be transmitted is sent to the second front-end processor of the intermediate management party, and the second front-end processor of the intermediate management party sends the data to be transmitted to the front-end processor of the receiver, and the front-end processor of the receiver can perform preliminary processing and analysis on the received data, and forward the processed data to the data exchange platform of the receiver located at the back end. Among them, the data exchange platform of the sender and the front-end processor of the sender are both located in the intranet of the sender, the data exchange platform of the receiver and the front-end processor of the receiver are both located in the intranet of the receiver, and the front-end processor of the intermediate management party and the data exchange platform of the intermediate management party are both located in the intranet of the intermediate management party. It can be understood that the front-end processors mentioned in this embodiment can selectively perform preliminary processing and analysis on the received data.

[0055] It can be understood that the data exchange platform of the intermediate management party and the data exchange platform of the receiving party and the data exchange platform of the sending party have the same function, that is, the data exchange platform can perform preset processing on the data to be transmitted and monitor the target process. The data exchange platform of each participant can include three modules. The first module is used to store and unstore the data to be transmitted and to put the encoded data on the chain, wherein storage or unloading means entering the database corresponding to the data exchange platform or extracting it from the database. The second module is used for the transmission and encryption and decryption of the data to be transmitted. The third module is used to monitor the execution process of the first module and the second model. The data exchange platform introduced in this application can open up the data channels between various units and departments, further improve the level of informatization, integrate resources, and operate more efficiently. Provide full-process support for data extraction, packaging, encryption and decryption, transmission, and storage, and provide full-link monitoring function for data packet flow to help operation and maintenance personnel locate the data packet transmission process and status in time.

[0056] See also Figure 5 , Figure 5 It is a flowchart of another implementation method of the blockchain-based data transmission method provided by this application.

[0057] S51: The data exchange platform of the receiving party receives the data to be transmitted which is transmitted by the data exchange platform of the sending party through the network gate.

[0058] This implementation is executed by the data exchange platform of the receiving party, and the data exchange platform of the receiving party receives the data to be transmitted by the data exchange platform of the sending party through the network gate. Specifically, the data exchange platform of the sending party sends the data to be transmitted to the front-end processor of the sending party, and the front-end processor of the sending party transmits the data to be transmitted to the front-end processor of the receiving party through the network gate, and the front-end processor of the receiving party sends the data to be transmitted to the data exchange platform of the receiving party. It can be understood that the front-end processor of the receiving party can perform preliminary processing and analysis on the data to be transmitted before sending it to the data exchange platform of the receiving party.

[0059] For the specific execution steps of the data exchange platform of the sender, please refer to the aforementioned embodiment and will not be repeated here.

[0060] S52: Obtain the encoded data corresponding to the data to be transmitted from the blockchain.

[0061] In one embodiment, the coded data corresponding to the data to be transmitted may be obtained by encoding the data to be transmitted by the data exchange platform of the receiving party and uploaded to the blockchain. In other embodiments, the coded data corresponding to the data to be transmitted may be obtained by encoding the data to be transmitted by the data exchange platform of the intermediate management party and uploaded to the blockchain.

[0062] S53: Verify the data to be transmitted based on the encoded data.

[0063] In one embodiment, the data exchange platform of the receiving party can encode the received data to be transmitted to obtain the data to be verified corresponding to the data to be transmitted; determine whether the data to be verified and the encoded data are the same, and in response to the data to be verified and the encoded data being the same, determine that the verification of the data to be transmitted is passed.

[0064] In a specific implementation, the encoded data corresponding to the data to be transmitted in the blockchain is the target hash value. The data exchange platform of the recipient can perform a hash operation on the received data to be transmitted to obtain the hash value to be verified, and determine whether the hash value to be verified is the same as the target hash value. If they are the same, it is determined that the data to be transmitted has been verified; if they are the same, it is determined that the data to be transmitted has not been verified.

[0065] It is understandable that in other embodiments, the data to be transmitted may not be verified by the data exchange platform of the receiving party, and other nodes may be introduced to send the data to be verified to other nodes, and the other nodes obtain the encoded data on the blockchain and compare the encoded data with the data to be verified. If the comparison is consistent, it is determined that the verification is passed, and if the comparison is inconsistent, it is determined that the verification is not passed. The verification result is sent to the data exchange platform of the receiving party.

[0066] S54: In response to the verification being successful, the received data to be transmitted is sent to a receiving service system in the receiving party's intranet.

[0067] If the verification is successful, it means that the data to be transmitted received by the data exchange platform of the receiver is the same as the data to be transmitted in the sending business system of the sender, which means that the data to be transmitted received by the data exchange platform of the receiver has not been tampered with and the data is safe. Therefore, the safe data to be transmitted is sent to the receiving business system in the receiving party's intranet. In this way, the data security in the receiving business system can be guaranteed.

[0073] In one embodiment, the first data transmission device 70 also includes an encryption module, which is used to encrypt the data to be transmitted to obtain ciphertext data, or to encrypt the data to be transmitted and the encoded data to obtain ciphertext data before transmitting the data to be transmitted through the network gate to the data exchange platform of the recipient. The transmission module 73 is used to transmit the ciphertext data to the data exchange platform of the recipient through the network gate.
