[0032] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings.

[0033] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the concept of the present application, therefore the present application is not limited to the specific embodiments disclosed below.

[0034] The embodiment of the present application provides a block-based enterprise digital business card trusted verification method, which is used for the establishment of the enterprise digital business card in the tax business system, proposes a multi-dimensional digital business card trusted authentication method based on block chain, involves information collection module, performance evaluation module, smart contract, weight score, business card chaining, each authentication node synchronizes the block chain information to the distributed digital identity authentication system, obtains all digital certificates and their effective state, prevents digital identity data from being tampered with, digital identity information is traceable, improves the value of distributed digital identity and data, and quickly authenticates the digital business card with zero knowledge.

[0035] The method of the present application is based on encryption algorithm, block chain technology and existing financial and tax system, divides the enterprise information in multiple dimensions, and calculates the experience formula Obtain the credibility of the enterprise-0+zero knowledge proof.

[0036] As Figure 1 shown, the method specifically includes the following steps:

[0037] S1, create a block account for each enterprise in the system, obtain a unique account address, enterprise private key, public key, etc., for the identification of enterprise identity and the authorization of subsequent behavior.

[0038] Through investigation, collect enterprises of different properties in various industries nationwide for sampling and compare with the enterprise registration information of reliable channels such as industry and commerce, tax authorities, etc., to form the basic characteristic values Pi0 of various types of enterprises, and establish a basic characteristic library as an important basis for subsequent enterprise characteristic comparison.

[0039] The enterprise registers in the system and fills in the relevant information required by the system: enterprise name, enterprise certificate number, enterprise region, enterprise industry, business scope, certificate, etc. The collection of relevant information is completed, and the administrator submits the system.

[0040] S2, collect enterprise application information periodically or driven by events, and decompose it into multiple trusted features including data sources, information integrity, information modification, business participation, activity, and multiple dimensions V(n). According to the industry, nature of the enterprise, etc. Set the weight of each dimension as the basis model of the enterprise feature, and perform vector processing and normalization on the information collected by the enterprise to obtain a multi-dimensional vector V=(V0, V1, V2, …, V n ) and calculate the initial feature value according to the different weights Wj of each vector. If the feature value meets the expectation Pi0, the next step will be performed, otherwise the enterprise will be prompted to modify.

[0041] S3, set up an enterprise manager block account, compare the enterprise information basic information including: enterprise name, registered capital, type, status, registered capital, business scope with the business registration information, and submit the block chain by the enterprise manager through the smart contract after meeting the expectations. The smart contract calculates the initial credit score according to the preset formula where Vj is the component of the collected data, Wj is the weight of each component, and Ai is the weight average of i enterprise, and K(i) = ||P i - i0 || 2 , Ai*Pi as the initial credit score, and the information is written into the block after the calculation is completed. Distributed in each node to form an initial credit score, generate a digital business card for the enterprise on the blockchain, and automatically synchronize to each node.

[0042] S4, collect business data during the enterprise financial activity process, such as invoice issuance, inspection, business accounting, logistics, transactions, contract performance, and information of counterparties. Through frequency, completion, quantity, etc. Statistical data, the information module collects its statistical data regularly, and these collected dynamic data are also subjected to vector processing and normalization. The enterprise manager block account is submitted to the block, and the formula is applied. After calculation by the smart contract, update the credit level information in the digital business card node, and at the same time save the enterprise information credit level of the block before the update in the block, which can be used as historical query. The block address of the business card is used as the id of the digital business card.

[0043] The sources of credit changes for a company's business card are twofold: first, company information submitted by the company's administrators after review; and second, the system periodically collects relevant information. The collection and update time can be set and adjusted according to actual business needs, such as recalculating once a year. The content of the company's digital business card includes: {Company Name, Company Certificate Number, Company Region, Company Industry, Credit Rating, Timestamp, Hash Block, and Business Partner Map}, which is stored as an array to store the information after each calculation and change, and saves the update records for the most recent 5 years.

[0044] Every time the business card information is changed, it is automatically synchronized to all nodes. The business card ID can be used to query the company's publicly available basic information and credit rating, and the process of changing the company's information can be traced.

[0045] S5. The establishment of an interactive evaluation system: After enterprises establish a relationship within the system, they can rate each other's contract performance. After a communication and interaction period, the system automatically submits the rating to the smart contract. The smart contract determines whether the submitting enterprise is a business partner of the other enterprise; only business partners can authorize rating. The smart contract calculates the weight based on the proportion of the submitting enterprise's total contracts. N is the number of companies, where Qj is the rating of company j, Ij is the weight of company j, and Si is the average weight of the ratings of other companies to company i. i ×Ws+Ci×W c ) / (W s +W c Where Ws represents the weight of the score in relation to the company's credit, Ci represents the company's basic credit, and Wc represents the weight of the basic credit. After calculation, the company's credit is written into the block. This creates a secure, reliable, tamper-proof, and zero-knowledge verification digital business card for the company.
