As shown in fig. 1-2, a transaction data processing method for facilitating tax fast inspection includes the following steps:
step S1: acquiring the transaction data, and performing signature determination on the transaction data; when the transaction data is stamped, both transaction parties are required to stamp the transaction data so as to ensure the true validity of the transaction information.
Step S2: the method comprises the steps of obtaining the account data of the transaction, wherein the account data are a combination of a material account, a material flow account, a fund account and a transaction account, scoring the material account, the material flow account, the fund account and the transaction account respectively, judging whether the scores are larger than a threshold value, and executing step S3 if the scores are larger than the threshold value;
Step S3: acquiring a current transaction evidence chain data packet, wherein the evidence chain constructs the whole process of the current transaction, and each link can check each related original credential data acquired by the transaction data;
Step S4: and uploading transaction data, ledger data and evidence chain data packets.
When tax auditing is carried out, the transaction data of each time is required to be checked and cross-compared, whether the transaction data is matched with the transaction records or not is determined, and whether the tax has a problem or not is determined. However, due to the fact that information islands exist among all parties, data cannot be interconnected, and therefore third-party verification and authentication are lacked in related transaction data of a supply chain. For this purpose, the invention packages and uploads transaction data, ledger data and evidence chain data. When a certain transaction is required to be checked, a corresponding file can be downloaded, and the transaction data of the time exist in the file, wherein the transaction data of the time are required to be signed by a corresponding company so as to ensure that the data source is real and effective, and when the transaction data have a question, the data can be traced. And the material account, the material flow account, the fund account and the transaction account exist in the account data, the same associated data exist among the four accounts, the real effectiveness among the four accounts is immediately scored through the same associated data, and when the data is larger than a threshold value, the account data is real data, and the credibility is high. The third layer is an encrypted transaction evidence chain data packet; the transaction evidence chain constructs a complete transaction chain from suppliers, the mass-ceramic company, ticket receiving units, goods using units, and the corresponding original credential data of each link in the transaction can be seen through the chain. The whole data product is built on the block chain, so that the reality, the completeness and the non-falsification of the data are ensured.
The five-in-one tax check requirement is constructed through the cross verification of the material standing account, the material flow standing account, the fund standing account and the transaction standing account, the authenticity of the transaction service is verified, and the pain points that the industrial raw material cost is difficult to identify and the tax is difficult to finish are solved.
Preferably, the transaction data in the step S1 includes a trade order number, an applicant, an application date, a total amount of the present transaction, and a transaction date.
Preferably, the ledger data includes sales invoice data, contract data, pound sheet information data, track information data, transaction body information, and payment voucher data.
Preferably, the specific process of scoring the material account, the material flow account, the fund account and the transaction account is as follows:
scoring is carried out by the condition that whether material data fields in three data tables of sales invoice data, contract data and pound bill information data are matched with each other or not and whether the number fields of materials are consistent or not, so that scoring of a material standing book is formed;
Scoring is carried out according to the conditions that whether the delivery addresses, the receiving addresses and the receiving and delivering address positioning match with each other or not in the three data tables of contract data, invoice information data and track information data are consistent, so that scoring of the logistics ledger is formed;
Scoring is carried out according to the conditions that whether the receiving and dispatching addresses in the track information data, the contract data and the transaction main body information are consistent with each other, and whether the mutual matching of the transaction main body address and the receiving and dispatching address positioning is consistent or not, so that scoring of a transaction account is formed;
and scoring is carried out according to the condition that whether the receipt and payment person, the billing body and the transaction amount are matched with each other or not in the three data tables of the transaction body information, the payment receipt data and the sales invoice data are consistent, so that the scoring of the fund ledger is formed.
When scoring is carried out, if the fields used for matching are the same, a score of 1 is obtained, and if the fields are different, a score of 0 is obtained; for example, in the material ledger, the sales invoice data comprises the names, specifications, quantity, price, sales amount, freight and insurance fees, invoicing date, payment conditions and other content vouchers of the sold commodities. The contract data also contains the names, specifications, quantity, price and sales amount of the sold goods, and the pound bill information data contains information for writing and understanding the types, names, quantity, weight and the like of the goods; at this time, the names of the sold goods in the sales invoice data, the names of the sold goods in the contract data and the goods names in the pound bill data are mutually matched and judged in pairs, the condition that the goods name fields are mutually consistent is judged to score, and then the data of the specification, the quantity and the like are judged in the same mode. The final score of the material ledger is obtained, and because the score is not full due to the possible error in input, the score threshold is set in the invention, and only the material ledgers with the score higher than the threshold can be considered to be valid. Similarly, the logistics ledger, the transaction ledger and the fund ledger are respectively obtained through the method. Because the ledger data are recorded by different departments of sources, information islands exist among a plurality of departments, the data volume is large, the difficulty of communicating and counterfeiting is high, and the method can fully utilize the full consistency of five-stream information, namely information stream, bill stream, contract stream, transport stream and fund stream, thereby verifying the authenticity of economic service.
Preferably, step S4 further includes obtaining identity information of both the current transaction parties, taking the identity information of both the current transaction parties as download verification information, and uploading the download verification information, the transaction data, the ledger data and the evidence link data packet together.
In order to ensure the security of the data of the present transaction, the invention can acquire the identity information of both transaction sides as the download verification information, and only the data of both transaction sides can acquire the account data of the present transaction in the corresponding blockchain address. Ensuring confidentiality of transaction information.
