In addition, the sequence of steps in each method embodiment described below is only an example and is not strictly limited.

In order to facilitate understanding of the technical solution of the present embodiment, the following briefly describes the prior art: with the wide application of the receivable payment mode, the application of the receivable payment warranty financing is more extensive, and specifically, the receivable payment warranty financing means that under the condition that an enterprise sends an unexpired receivable payment formed by credit to a bank or a warranty institution in an agreement form, the latter provides the enterprise with comprehensive services of trade financing, receivable payment management, receivable payment collection, bad payment guarantee and the like.

In the upstream and downstream of a B-class supply chain of the Internet, a core enterprise occupies absolute position and speaking right, a large number of small B-class suppliers exist upstream, and the core enterprise generally proposes credit for an upstream first-class supplier and issues corresponding credit evidence for capital turnover and operational liquidity of the core enterprise, and the first-class supplier forms accounts receivable. In order to better acquire the fund flow, the primary supplier is conditionally transferred to a bank or a warranty organization in an agreement form, and the bank or the warranty organization provides financing services for the primary supplier and performs services such as receivables collection and the like for the core enterprise. However, the accounts receivable relate to the core enterprise billing, and the primary supplier generally takes paper commercial bills, so that the primary supplier can only transfer the accounts receivable to one secondary supplier, and cannot perform split transfer to a plurality of secondary suppliers, and in this way, a plurality of financial institutions repeatedly give credit to the same accounts receivable, thereby causing bad accounts of the financial institutions.

Fig. 1 is an overall flowchart of a data processing method according to an embodiment of the present invention; FIG. 2 is a schematic diagram of splitting billable information according to an embodiment of the present invention; fig. 3 is a schematic diagram of performing a verification process on all link data corresponding to the receivables information according to the embodiment of the present invention; referring to fig. 1 to 3, in order to overcome the above-mentioned drawbacks, the present embodiment provides a data processing method, which can implement digitization of invoicing information of accounts receivable based on a blockchain technology, split transfer of bills among suppliers, and support split transfer among unlimited levels of suppliers; in addition, the tree-shaped full link backtracking of accounts to be collected can be realized based on the block chain technology, and the occurrence of repeated credit granting can be avoided by utilizing the irreversible characteristic of the block chain.

It can be understood that the execution subject of the data processing method includes: an enterprise server/enterprise processor, an n-level vendor server (exemplified by a level one vendor server), an n +1 level vendor server (exemplified by a level two vendor server), and a financial institution server/financial institution processor, and the respective execution bodies may be implemented as software or a combination of software and hardware. Specifically, the method may include:

step 1: a core enterprise server (hereinafter referred to as a "first server") performs an operation of issuing an invoice for accounts receivable.

Specifically, the first server may obtain account data first, and the account data may include: account objects, account amounts, account-related details, and the like; and generating receivable account information according to the account data, and making an account receivable according to the receivable account information, wherein the receivable account making can comprise identification information corresponding to the account data.

In addition, the first server can call a pre-stored electronic signature certificate, and the electronic signature certificate is used for corresponding receivable billing to perform electronic signature, so that account information can be conveniently checked, and the receivable billing can have legal effectiveness so as to prevent enterprise repudiation.

step 2: after the electronic signature is completed, the first server writes the receivable billing information as a billing document into the block chain through an intelligent contract protocol; the blockchain may be a blockchain platform for supply chain financing.

It is understood that the method in this embodiment may further include: when the electronic signature of the receivable account billing fails, the first server is not allowed to write the receivable account billing into the block chain, and at the moment, the first server can be controlled to display the warning prompt information so as to prompt the user to process the account information in time in order to facilitate the user to know the progress of the account information in time.

step 3: after the invoicing of the receivable payment is written into the block chain, a primary supplier server (hereinafter referred to as a second server) corresponding to a primary supplier can read the invoicing document in the block chain through an intelligent contract protocol; the second server can carry out electronic signature on the invoicing document, and write the invoicing document after the electronic signature into the block chain again to form the circulated invoicing document with receivable accounts.

It is understood that the method in this embodiment may further include: when the second server fails to electronically sign the invoicing document, the second server is not allowed to write the invoicing document into the block chain, and at the moment, the first server can be controlled to display the warning prompt information so as to prompt the user to timely process the invoicing document, so that the user can timely know the progress condition of account information.

step 4: and the second server reads the account receivable invoicing document on the block chain through the intelligent contract protocol and can transfer the account receivable invoicing document.

As shown in fig. 2, assuming that the receivable billing documents are transferred to a secondary supplier server (hereinafter referred to as a "third server") corresponding to n secondary suppliers, that is, the receivable billing documents (parent billing documents) need to be split into n sub-documents, the sum of the split n sub-documents cannot exceed the total amount of the receivable billing documents, and each sub-document includes a unique identifier of the receivable billing documents, in general, the unique identifier may be a billing number of the receivable billing documents, and the unique identifier may be convenient for a financial institution (e.g., a bank) to obtain link information corresponding to the receivable billing documents so as to track, check and verify the link information.

It can be understood that when the parent invoicing document is split, if the parent invoicing document is split to have surplus, that is, the total amount corresponding to the parent invoicing document is greater than the sum of the amounts of all the split sub-documents, a surplus sub-document can be formed according to the surplus amount, and the surplus sub-document is written into the block chain through the intelligent contract protocol to be stored.

Similarly, after the third server receives the corresponding sub-document, the third server may perform re-assignment processing based on the sub-document, that is, the secondary supplier may split the sub-document as a total invoicing document again by applying the scene and the usage requirement, and transfer each split document to a third-level supplier server (fourth server) corresponding to n third-level suppliers, that is, the sub-document needs to be split into n documents, the sum of the sums of the split n documents cannot exceed the sum of the sub-documents, and the n documents include unique identifiers of the sub-documents (that is, the unique identifiers of the invoicing documents to be received), so that a tree link corresponding to the invoicing document to be received is formed, where the tree link information at least includes: the account payable system comprises a first server, an account payable billing document corresponding to the first server, a second server, a parent billing document corresponding to the second server, a third server, a child document corresponding to the third server, a fourth server and a document corresponding to the fourth server.

step 5: and the third server corresponding to each secondary supplier can receive the sub-documents sent by the second server, electronically sign the sub-document information and write the signed sub-document information into the block chain.

In addition, after the third server receives the sub-document, the sub-document billing information can be generated according to the sub-document information, the sub-document billing information is electronically signed, and the signed sub-document billing information is written into the block chain. Specifically, since the number of the secondary suppliers may be n, at this time, n sub-document billing information may be generated and may be written into the block chain through the intelligent contract agreement.

Repeating the steps 4 and 5 can realize that the supplier server corresponding to the n-level supplier splits the receivable bill and realizes the process of transferring the bill to the supplier server corresponding to the n + 1-level supplier, and the specific implementation process can refer to fig. 2.

step 6: the supplier server (n-level supplier server and/or n + 1-level supplier server) can initiate a warranty financing application to a financial platform server corresponding to a financial platform (such as a bank, a warranty organization and the like), can read an invoicing document corresponding to receivable information on an n-level supplier block chain through an intelligent contract protocol, and can split the invoicing document into 2 auditing documents after obtaining the invoicing document, wherein the method comprises the following steps: 1 financing sub-document +1 remaining sub-document, and it can be understood that when the whole invoice transfer is carried out on the invoice data, no remaining sub-document exists. When the remaining sub-documents exist, the n-level supplier server can carry out electronic signature on the remaining sub-documents and write the electronic signature into the supply chain insurance financing block chain platform through the intelligent contract agreement.

step 7: after the financial platform server receives the insurance management financing application and the financing sub-sheet, the full link of the financing sub-sheet can be backtracked through an intelligent contract, as shown in fig. 3, namely, the multi-branch tree link data formed corresponding to the collected account is backtracked and verified, the correctness of financing amount is ensured, and therefore repeated credit granting among a plurality of financial institutions is avoided.

step 8: after the financial platform server completes verification processing, if all link data pass verification, electronic signature can be carried out on the financing sub-list, and the financing sub-list is written into the supply chain insurance financing block chain platform through an intelligent contract protocol.

According to the data processing method provided by the embodiment, the block chain digital processing is carried out on the account receipt and billing information, the trueness and the credibility of the account receipt and billing information are effectively ensured by utilizing the characteristic that the block chain cannot be tampered, and the enterprise, the supplier or the bank can be effectively prevented from repudiation by the digital signature mode of the account receipt information; secondly, the operation of splitting the corresponding receipt bill is realized based on the block chain, and the fast and convenient transfer of the receivable bills among the multi-stage suppliers can be realized based on the supply chain, so that the quality and the efficiency of processing the corresponding receipt information are effectively improved; finally, on the aspect of financing management, the full link data of the corresponding account receipt billing information is subjected to backtracking verification processing through an intelligent contract agreement, the safety and reliability of financing and paying of financial institutions are ensured, the pneumatic control cost of the financial institutions is reduced, the situation that multiple financial institutions repeatedly give credit to the same account receipt is effectively avoided, the normal operation of the service of prompting receipt of the account receipt and the like for core enterprises is further ensured, the practicability of the method is improved, and the market popularization and application are facilitated.
