[0056] Financial services, used to introduce third-party investment and increase the success rate of transactions;

[0057] Tax supervision is used to collect taxes generated during the transaction process and ensure the legality of goods transactions.

[0058] Transaction data storage subsystem, used for:

[0059] Adopt the five-flow integration data collection and storage method to associate the five-flow data so that each flow can verify and complement each other to form a complete business chain; the five-flow integration data collection and storage is to integrate the contract flow, capital flow, invoice flow, logistics flow and information flow to achieve centralized data management and storage; for example: through the contract number, the transaction terms in the contract flow are associated with the payment record in the capital flow, the invoice information in the invoice flow, the delivery certificate in the goods flow and the business communication record in the information flow; comprehensively collect all kinds of data involved in the five flows to avoid data loss, and provide sufficient data support for the verification of business authenticity and business analysis. For example: in a sales business, ensure that all relevant data such as sales contracts, customer payment records, sales invoices, goods delivery orders, and communication records between business personnel and customers are collected; as shown in the following table:

[0060]

[0061]

[0062] Table 1: Five-stream data display table

[0063] Clean, organize and verify the collected data to ensure the accuracy, consistency and timeliness of the data. For example, verify the key information such as tax rate and amount in the invoice data, and compare and review the transportation time in the cargo flow and the delivery time agreed in the contract. Establish a data warehouse to store and encrypt the five-flow integrated data by subject, and establish a data access control mechanism and a data quality monitoring indicator system.

[0064] The transaction data storage subsystem includes:

[0065] The data processing module is used to identify and remove duplicate records in the five-stream data. For example, in the capital flow data, there may be duplicate payment records caused by system failure or operational errors. The duplicate data can be determined and deleted by comparing key factors such as payment time, amount and information of both parties to the transaction; the erroneous information in the five-stream data can be corrected. For example, in the invoice flow data, there may be incorrect tax rates. By comparing with tax policies and relevant contract terms, the erroneous tax rates can be corrected; the missing values ​​in the five-stream data can be supplemented, and different processing methods can be adopted according to the importance and accessibility of the data; if the data can be derived or supplemented by data from other flows, such as the delivery date in the contract flow If the missing value of transportation time can be supplemented by the shipping date in the date and cargo flow, it will be supplemented; if it cannot be supplemented, it will be marked as missing data, and whether to further investigate and obtain it will be decided based on business needs; the data in different formats in the five-stream data are converted into a unified standard format, for example: the date format is unified as "YYYY-MM-DD", and the amount data is uniformly retained to two decimal places, etc.; the five-stream data are classified and encoded for easy storage and query; for example: the business type is classified and encoded, the sales business is coded as "01", the procurement business is coded as "02", etc.; the goods and services are classified and encoded, and different goods or services are assigned corresponding codes according to industry standards or internal enterprise standards.

[0066] The data storage module is used to establish a data warehouse to store, deeply analyze and mine the five-stream data. It supports the integration and conversion of five-stream data from different data sources, organizes and stores them by subject, and provides support for data analysis. For example, by building a data warehouse with a sales theme, the contract flow, capital flow, invoice flow, logistics and information flow data related to procurement business can be stored in a centralized manner, making it convenient for enterprises to conduct sales performance analysis, customer behavior analysis, etc.

[0067] The security management module is used to establish a data access control mechanism and assign different access levels according to the user's role and authority. For example, financial personnel can access and modify the capital flow and invoice flow data, business personnel can access the contract flow and information flow data, and only senior management or data managers can have full access to all five flow data. Symmetric encryption algorithms are used to encrypt the five flow data, especially data involving corporate secrets, customer privacy and financial information. For example, symmetric encryption is used to encrypt the commercial confidentiality clauses in the contract and the customer's bank account information to ensure the security of data during storage and transmission. Regularly back up the five flow data and formulate a data recovery plan. The backup data can be stored in an off-site data center or cloud storage platform to prevent data loss due to natural disasters, system failures or human damage. For example, enterprises can perform full backups of important business data every day, incremental backups every hour, and regular backup data recovery drills. Establish a data quality monitoring indicator system to monitor the accuracy, completeness, consistency and timeliness of data in real time. For example, monitor whether the tax rate and amount in the invoice flow data comply with the tax policy, whether the delivery date in the contract flow is consistent with the arrival date in the goods flow, etc. When data quality problems are found, the problem handling process is initiated in a timely manner. Through data tracing, the root cause of the problem is found, and appropriate measures are taken to correct it. For example, if the payment amount in the fund flow data is found to be inconsistent with the amount in the contract flow, by checking the operation records of the financial system, contract terms and payment approval process, it is determined whether the problem is caused by system failure or human error, and the corresponding treatment is carried out.

[0068] The anti-tampering module is used to use data signing technology to perform anti-tampering processing on the data to prevent the five-stream data from being maliciously tampered with during transmission or storage. Specifically, it includes the following steps:

[0069] Sort the data to be signed according to the data name. The sorting rule is to sort in ascending order according to the ASCII code value of the data name. If the same characters are encountered, they are sorted in ascending order according to the ASCII code of the second character, and so on. This can ensure the consistency of the data content of both the signature and the verification. Combine the sorted data and the corresponding value into the format of "data = data value", and connect these data with the & character to generate a digest string. Calculate the digest value of the digest string through the digest algorithm, and use the asymmetric encryption algorithm to encrypt the digest value with the client's private key to generate a signature. Send the five-stream data content, character encoding, and signature method information to the server. The server receives Then, the same sorting and concatenation operations are performed on the data, and the signature is decrypted by the public key to obtain the summary value of the signer; the decrypted summary value is then compared with the summary value of the signature verifier. If the two are equal, the signature verification is successful, indicating that the data has not been tampered with; otherwise, the opposite is true; specifically, the summary value is obtained by performing a summary calculation on the data to be signed, and then the summary value is asymmetrically encrypted with the signer's private key to generate a signature; the signature verification process is to perform the same summary calculation and public key decryption operations on the received data, and finally compare the decrypted summary value with the summary value of the signature verifier to see if they are consistent; this effectively prevents the five-stream data from being maliciously tampered with and ensures the integrity and security of the data.

[0070] The transaction data display subsystem is used to:

[0071] A hash algorithm is used to establish associations between data based on unique fields or attributes in the five-flow data, so that the contract flow, capital flow, invoice flow, goods flow and information flow are integrated together, and the overall picture of the business is presented in an intuitive and clear manner; helping enterprises to better manage and monitor business processes and ensure the authenticity and compliance of the business. The following is a solution for the integration and display of five-flow data.

[0072] Transaction data display subsystem, including:

[0073] The data integration module is used to match data records with the same unique identification value in different data sources in the five-stream data using a hash algorithm to determine the same attributes of the data records; the unique identification mentioned above includes: contract number, order number, invoice number, waybill number, etc., which are unique in their respective business flows and can accurately represent a certain business entity or transaction activity. By matching data records with the same unique identification value in different data sources, such as contract flow, capital flow, invoice flow, logistics and information flow, it is determined that these records belong to the same business event; for example: if there is a contract with a contract number of "HT001" in the contract data, and the corresponding "HT001" identification can also be found in the capital payment record, invoice information, cargo transport order and business communication record, then these records can be associated together.

[0074] Specifically, the application steps of the hash mapping method are as follows:

[0075] Considering the efficiency of five-stream-in-one data acquisition, the unique identifier of the data is quickly matched and the CRC32 function is used to generate the hash value;

[0076] import hashlib

[0077] data="unique_identifier_123"

[0078] hash_object=hashlib.crc32(data.encode()).hexdigest()

[0079] print(hash_object)

[0080] For the unique identification field in each data source, the above function is used for hash operation. The unique identification of the business flow is the contract number, the unique identification of the logistics is the waybill number, the unique identification of the capital flow is the capital flow, the unique identification of the bill flow is the invoice number, and the unique identification of the information flow is the contract number. The hash function is called for the unique identification of the above five flows to obtain the corresponding hash value; the generated hash value is stored in the corresponding data structure, and a hash value set, such as the contract number hash value set, is searched in another hash value set, such as the invoice number hash value set, to see if the same value exists; when two hash values ​​are found to be the same, the corresponding unique identification cannot be directly determined to match, and an accurate comparison is performed through the original unique identification. After the above steps, the five-flow data can be quickly associated and the result set formed by the five-flow display can be found.

[0081] The data display module is used to display the basic information of all contracts in the form of a list. The basic information includes: contract number, signing parties, signing date, contract amount, contract period, etc. The display methods include: displaying the time distribution of contract signing and the distribution of contract amount through charts. For contracts being executed, the progress of the contract execution is displayed through progress bars and status indicators, such as: signed, being executed, completed, etc. The specific display methods are as follows:

[0082] Logistics display:

[0083] It displays the transportation track, inventory status, delivery and receipt time of goods, etc. It shows the transportation route of goods through a map, uses a bar chart to show the inventory levels of different warehouses, and uses a line chart to show the inventory change trend. For the goods in and out of the warehouse, it can provide detailed records, including operation time, operator, quantity of goods and other information.

[0084] Fund flow display:

[0085] Display the inflow and outflow of funds, including the payer, payee, amount, payment time, payment method, etc. Use a bar chart to show the total amount of fund inflow and outflow in different time periods, and use a line chart to show the changing trend of fund flow. For large-value fund transactions, highlight them and provide detailed transaction information and approval process records.

[0086] Ticket flow display:

[0087] Display the basic information of the invoice, such as invoice number, invoice date, invoice amount, tax rate, buyer and seller information, etc. Display all invoices in the form of a table, and use charts to show the distribution of invoice amounts, the time distribution of invoice issuance, etc. For abnormal invoices, such as amounts that do not match the contract, duplicate invoices, etc., they are marked with different colors and early warning information is provided.

[0088] Information flow display:

[0089] Display various information exchange records in the business process, such as emails, text messages, instant messaging records, etc., use a timeline to show the sending and receiving time of the information, and use a list to show the content of the information and the sender and receiver. For important information exchanges, highlight them and provide relevant attachments and links.

[0090] In order to better demonstrate the operation process of a transaction platform based on the authenticity of renewable resource business, the present invention provides a transaction method based on the authenticity of renewable resource business, comprising the following steps:

[0091] Step 1: When the business nodes of the entire renewable resource transaction process are completed through blockchain technology, the five-stream data will be uploaded to the blockchain system for storage, and transaction data evidence query services can be provided to third parties;

[0092] Step 2: Establish a data warehouse to associate the five streams of data so that each stream can verify and complement each other to form a complete business chain, and store and encrypt them by topic;

[0093] Step 3: Establish a data access control mechanism and a data quality monitoring indicator system, and use data signing technology to prevent data tampering;

[0094] Step 4: Use the hash algorithm to associate the attributes between the five data flows, so that the contract flow, capital flow, invoice flow, goods flow and information flow are integrated together, and the overall picture of the business is presented in an intuitive and clear way;

[0095] Step 5: Use charts to show the time distribution of contract signing and the distribution of contract amounts, and use progress bars and status indicators to show the progress of contract execution.
