[0049] With the development of the economy, more and more companies need to conduct financing and other businesses in order to achieve rapid development. When conducting financial businesses such as financing, the company needs to first process the business on the supply chain financial platform, and then the supply chain financial platform will sign the corresponding business data, and finally the supply chain financial platform will send the signed business data to the funding party. However, when the funding party and the supply chain financial platform do not belong to the same legal entity, the supply chain financial platform can tamper with the business data without the knowledge of the company and the funding party, that is, the data provided to the funding party is different from the business data operated by the company, that is, the existing business processing method has the risk that the supply chain financial platform may tamper with the business data, resulting in low security of the business processing method.

[0050] Therefore, in response to the above problems, the embodiments of the present application provide a business processing method, apparatus, device and readable storage medium, which can improve the security of business processing.

[0051] See also Figure 1 A business processing method provided in an embodiment of the present application can be applied to a first server, wherein the first server can be a funding party server, and the funding party server refers to a server used by an institution such as a bank that can provide financing services to an enterprise through a second server, and specifically includes the following steps.

[0052] S101: Receive uplink information sent by a second server.

[0053] In this embodiment, the first server may first receive the on-chain information sent by the second server. It is understandable that the second server may specifically be a supply chain financial platform server, which will upload the business data to be verified to the blockchain and send the corresponding on-chain information to the first server. The first server may receive the on-chain information sent by the second server, so as to obtain the business data to be verified from the blockchain and send the business data to be verified to the client for verification, thereby avoiding the possibility of the second server tampering with the business data, thereby improving the security of business processing. The business data to be verified may be the data obtained by signing the original business data on the client, and the on-chain information may include the storage location information of the business data to be verified on the blockchain.

[0054] It should be noted that the first server can monitor the first blockchain node. When the business data sent by the second server is uploaded to the chain, the first blockchain node can directly send the uploaded information to the first server.

[0055] S102. Obtain the business data to be verified from the first blockchain node according to the on-chain information.

[0056] In this embodiment, after receiving the on-chain information sent by the second server, the first server can obtain the business data to be verified from the first blockchain node according to the on-chain information. It can be understood that the first blockchain node is connected to the first server, and can specifically be a funding party blockchain node, which is a node for uploading or downloading data in the blockchain. The first blockchain node and the second blockchain node corresponding to the second server are located in the same blockchain, and the second blockchain node can specifically be a supply chain financial platform blockchain node. Specifically, the first server can send the on-chain information to the first blockchain node, and the first blockchain node downloads the corresponding business data to be verified from the blockchain and sends it to the first server, so that the first blockchain node can obtain the business data to be verified, so as to send the business data to be verified to the client for verification, avoiding the possibility of the second server tampering with the business data, thereby improving the security of business processing.

[0057] In one possible implementation, the first server can obtain the encrypted business data to be verified from the first blockchain node according to the chain information; receive the key sent by the second server; decrypt the encrypted business data to be verified according to the key to obtain the business data to be verified. It can be understood that in order to avoid the illegal acquisition of business data and further improve the security of business processing, the second server will first encrypt the business data to be verified by the key before uploading the business data to the blockchain to obtain the encrypted business data to be verified, and upload the encrypted business data to the blockchain, and send the chain information and key to the first server. After receiving the chain information and key, the first server can first obtain the encrypted business data to be verified from the first blockchain node according to the chain information, and then decrypt the encrypted business data to be verified according to the key to obtain the business data to be verified, so as to send the business data to be verified to the client for verification, thereby avoiding the possibility of the second server tampering with the business data, thereby improving the security of business processing.

[0058] S103: Send the service data to be verified to the client.

[0059] In this embodiment, after obtaining the business data to be verified, the first server can send the business data to be verified to the client so that the enterprise user can verify whether the business data to be verified is the same as the business data generated by business processing on the second server, thereby avoiding the possibility of the second server tampering with the business data and improving the security of business processing.

[0060] In one possible implementation, after sending the business data to be verified to the client, the first server can also receive the verification result sent by the client; if the verification result is verification passed, the trusted identifier is added to the business data to be verified to obtain the trusted business data; the trusted business data is uploaded to the blockchain through the first blockchain node. It is understandable that the first server can also add a trusted identifier to the business data to be verified that has been verified and confirmed by the enterprise user according to the verification result returned by the client, obtain the trusted business data, and upload the trusted business data to the blockchain, so that the first server or other organizations in need and with authorization can query all trusted historical business data of the enterprise through the blockchain.

[0061] It can be seen that a business processing method is provided in an embodiment of the present application, which is applied to a first server. Since the second server uploads the business data to be verified to the blockchain and sends the on-chain information to the first server, the first server can obtain the business data to be verified from the blockchain according to the on-chain information, and send the business data to be verified to the client for verification, thereby avoiding the possibility of the second server tampering with the business data, thereby improving the security of business processing.

[0063] S201: Receive business data to be verified sent by the client.

[0064] In this embodiment, the second server may first receive the original business data sent by the client. It is understandable that the enterprise user may open the browsing page of the second server through the client, perform business processing on the browsing page of the second server, and generate corresponding business data. The client may send the business data as business data to be verified to the second server. Specifically, the client may also sign the generated business data through an electronic certificate, such as a U-shield, to obtain the original business data, to indicate that the original business data is generated by the enterprise user operating on the client.

[0065] In one possible implementation, the original business data sent by the client is received; the signature of the original business data is verified; if the verification is successful, the original business data is determined as the business data to be verified. It is understandable that in order to further determine the validity of the received business data to be verified, the second server can perform signature verification on the received original business data that has not been verified, and after the signature verification of the original business data is successful, the original business data is determined as the business data to be verified for subsequent verification.

[0066] S202: Upload the business data to be verified to the blockchain through the second blockchain node, and generate on-chain information.

Wherein the on-chain information may include the storage location information of the business data to be verified on the blockchain.

[0068] In one possible implementation, the second server can encrypt the business data to be verified to obtain encrypted business data to be verified; and upload the encrypted business data to be verified to the blockchain through the second blockchain node. It is understandable that in order to prevent business data from being illegally obtained and further improve the security of business processing, the second server will first encrypt the business data to be verified by a key before uploading the business data to the blockchain to obtain encrypted business data to be verified, and upload the encrypted business data to be verified to the blockchain, and send the chain information and key to the first server, so that after receiving the chain information and key, the first server can first obtain the encrypted business data to be verified from the first blockchain node according to the chain information, and then decrypt the encrypted business data to be verified according to the key to obtain the business data to be verified, so as to send the business data to be verified to the client for verification, thereby avoiding the possibility of the second server tampering with the business data, thereby improving the security of business processing.

[0084] S5. Upload the business data to be verified to the blockchain through the second blockchain node, and generate on-chain information.

[0085] In this embodiment, after generating the business data to be verified, the second server can upload the business data to be verified to the blockchain through the second blockchain node and generate the on-chain information. It can be understood that the second blockchain node is a node connected to the second server for uploading or downloading data in the blockchain.

Since the second server uploads the business data to be verified to the blockchain and sends the on-chain information to the first server, the first server can obtain the business data to be verified from the blockchain according to the on-chain information, and send the business data to be verified to the client for verification, so the possibility of the second server tampering with the business data is avoided, thereby improving the security of business processing.

[0090] See also Figure 3 , an embodiment of the present application provides another business processing method, which specifically includes the following steps.

[0091] P1 is a browser in the PC environment of enterprise users. The supply chain finance platform system page is displayed in the browser. Enterprise users complete supply chain finance business operations on the page, such as debt issuance. At the same time, the enterprise U shield is used to complete the business data signature.

[0092] P2 is a supply chain finance platform service. P1 sends the business operations and U-shield signatures of enterprise users to P2. After P2 completes the signature verification and related business logic, it encrypts the business data and sends it to P3 to complete the business data chain.

[0093] P3 is a blockchain node deployed on the supply chain finance platform operator, and forms a blockchain service with F3. When P3 receives P2's request to upload data to the blockchain, it reaches a consensus with F3 and completes the upload of business data to the blockchain. After that, it notifies P2 of the upload result. P2 sends the uploaded information and key to F2. Asymmetric key encryption is used to ensure secure key transmission.

[0094] F3 is a blockchain node deployed on the funding side, and forms a blockchain service with P3.

[0095] F2 serves the funding party and is deployed on the funding party. After F2 receives the on-chain information and key from P2, it queries the on-chain business data ciphertext from F3 and decrypts it with the key to obtain the original business data. The original business data will be displayed in F1.

[0096] F1 is a browser in the PC environment of the enterprise user. The funding party system page is displayed in the browser. The page contains the business data operated by the enterprise user in P1, which is provided by F2. There is a link in P1 that can jump to F1. When the enterprise user completes the supply chain financial business operation in P1, he can jump to F1 through the link to confirm whether the business data displayed in F1 is consistent with P1. If it is consistent, it proves that the supply chain platform has not tampered with the original intention of the enterprise user. If it is inconsistent, the enterprise user can terminate the business and then contact the supply chain financial platform and the funding party to handle the exception.

[0097] In the blockchain composed of P3 and F3, business data confirmed by enterprise users will be stored and cannot be tampered with. Therefore, the funding party or other organizations in need and with authorization can query all credible historical business data of the enterprise through the blockchain.

[0098] It can be seen from this that the embodiment of the present application provides a business processing method and designs a secondary confirmation mechanism to display the business data operated by enterprise users in the funding system to prove that the supply chain finance platform has not tampered with the business data during the flow of business data.
