Description

Technical Field

[0001] The present invention relates to the field of blockchain technology, and in particular to a tax planning and tax-related blockchain physical examination system. Background Art

[0002] Blockchain technology originated from cryptography and was first introduced in 1976 by Bailey W. Diffie and others in the form of cryptographic currency. Its essence is a shared database with the characteristics of being “unforgeable”, “traceable throughout the process”, “traceable”, “open and transparent”, and “collectively maintained”.

[0003] At present, medical examination data is mainly managed by medical institutions, and there are strict restrictions and regulations on the transmission and sharing of important personal information. Physical examination data are scattered in various medical institutions, and the physical examination data standards of different medical institutions are not unified, resulting in low interoperability of medical information systems among institutions. As a result, a common phenomenon has been created: people cannot directly use their physical examination data in a previous hospital in one hospital, and can only re-examine. In addition, the payment income and expenditure and tax planning information of patients cannot be accurately and effectively calculated between hospitals, making the exchange and sharing of medical examination data very difficult, seriously hindering the effectiveness of physical examination reports and the timeliness of tax planning information statistics, and there is a certain risk of information leakage. According to Article 40 of the Regulations for the Implementation of the Enterprise Income Tax Law: "The physical examination fees incurred by enterprises for employees can be deducted within 14% of the total wages and salaries." It is a key project of corporate tax planning. For this reason, a tax planning-related blockchain physical examination system is proposed to solve the above problems. Because the tax network is very complex, it is very difficult for large enterprises to use information from the tax blockchain network for tax planning and control. It is also difficult to improve the efficiency of information interaction, especially the efficiency of information interaction in the tax blockchain network. Summary of the invention

[0004] The purpose of the present invention is to provide a tax planning and tax-related blockchain physical examination system, which can solve the shortcomings of the existing technology that the information validity of the physical examination system and the timeliness of tax planning information statistics are seriously lacking, and can improve the efficiency of physical examination-related tax planning information statistics. In the preferred solution, the response delay of the blockchain network can also be reduced.

[0005] In order to solve the above technical problems, the present invention adopts a technical solution: a tax planning and tax-related blockchain physical examination system, including a tax planning module and a medical health examination device, the tax planning module and the medical health examination device are connected to the sending module through a wireless or wired network, the sending module is connected to the blockchain network, the sending module is connected to a judgment unit through a wireless or wired network, the judgment unit is connected to multiple user nodes, and the user nodes are interactively connected to each other with an audit node and a supervision node;

[0006] The audit node is connected to the tax planning module, which is used to calculate and store the user node information. The tax planning module includes a tax planning calculation unit and an encryption storage unit. The encryption storage unit encrypts and packages the calculation data of the tax planning calculation unit and transmits it to the sending module.

[0007] The user node is connected to the audit module. The audit module includes an audit node audit unit and a user node audit unit. The audit node audit unit is connected to the blockchain network. The user node audit unit is interactively connected with the blockchain network for information. The blockchain network also includes a tax planning control output and storage module.

[0008] In the preferred solution, the user node is a blockchain physical examination terminal, which includes an input module, an output module and a processing module. The input module includes an ID card scanner, a camera, a fingerprint collector and a payment unit.

[0009] In the preferred scheme, a medical health examination device is also provided. The medical health examination device is used to send the physical examination report to the judgment unit according to the requirements of the blockchain network. The judgment unit is used to judge the consistency between the physical examination report and the user node information. When the consistency test is passed, the judgment unit sends the physical examination report to the blockchain network through the sending module.

[0010] In the preferred solution, the audit module uses the DPOS consensus protocol to select audit nodes with audit rights.

[0011] In the preferred solution, the regulatory nodes include tax administration departments, industrial and commercial administration departments, banking regulatory departments and other credible third-party institutions, and the blockchain network distributes regulatory keys to each regulatory node.

[0012] In the preferred solution, the user node is also used to query the information of the tax plan and physical examination report through the address of the hospital network end, and perform identity authentication or decryption through the public key and private key;

[0013] The user node divides the information related to the physical examination into two parts. One part is the tax planning calculation information, which includes the user identity, physical examination time and physical examination amount; the other part is the physical examination report information, which includes the specific information of the physical examination items and physical examination results. The physical examination report information is based on the random inspection information requirements of the blockchain network and is submitted to the medical health examination equipment through the user node.

[0014] In the preferred solution, the encrypted data packets produced by the tax planning module and the physical examination reports produced by the medical health examination equipment are encrypted by private keys, and then the encrypted data are uploaded to the blockchain network and blocks are produced.

[0015] In the preferred solution, the blockchain network generates new blocks through the hospital's network nodes, and then adds them to the main chain to form a permanent storage of physical examination data and tax planning data, and adds a timestamp through a hash function; the timestamp is used to ensure that the block follows the timing link in the blockchain network; the blockchain network is a Merkle tree-based structure.

[0016] In a preferred solution, the blockchain network includes a business chain network and multiple query sub-chain networks, and the business chain network is connected to the multiple query sub-chain networks through an index linked list.

[0017] In the preferred solution, the query subchain network establishes the corresponding blockchain according to the data update load time, and the update load time is the time required for each business to initiate modification and confirm the data;

[0018] The proposed update load of each query subchain network is set to an average value, and the proposed new data is updated to the query subchain network with a load lower than the average value first;

[0019] The maximum value of the update load is also set. When the data chain reaches the maximum value of the update load, no new data will be added.

[0020] When the update load time of all query subchain networks exceeds the maximum value, a new blockchain is established as the query subchain network;

[0021] The chain head of the query subchain network contains the data list of the current blockchain and the data expiration time. When the data expiration time is reached, the corresponding data in the current blockchain is deleted. The chain head also includes the last update load time data.

[0022] The tax planning and tax-related blockchain physical examination system proposed by the present invention can effectively solve the problem that the tax planning and tax-related information and physical examination information generated by traditional medical physical examinations are slow to transmit and query and there are data security risks; a structured, non-forgeable electronic physical examination data and tax system is established by using distributed recording and storage technology based on blockchain, which has high security. The risk of uncontrollable leakage of sensitive information in physical examination data is reduced, and the security and credibility of physical examination data are increased; at the same time, the real-time and accurate data requirements of corporate tax planning and tax review by tax authorities are met. In the present invention, the information related to the physical examination is divided into two parts, including tax planning calculation information with a very small data volume, which is used for bookkeeping operations. The physical examination report information with a large data volume is used for credibility verification according to the random sampling information requirements of the blockchain network. With this scheme, on the basis of ensuring the reliability of information, the resource consumption of the blockchain network by redundant data is also avoided. The query sub-chain network set in the blockchain network adopts the update load time to evaluate the response speed of the query sub-chain network, thereby greatly improving the response and processing efficiency of the entire blockchain network. The set data expiration time can automatically delete the invalid data, further improving the utilization efficiency of resources. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figure 1 , 3A tax planning and tax-related blockchain physical examination system includes a tax planning module and a medical health examination device. The tax planning module and the medical health examination device are connected to a sending module through a wireless or wired network. The sending module is connected to a blockchain network. The sending module is connected to a judgment unit through a wireless or wired network. The judgment unit is connected to multiple user nodes. The user nodes are interactively connected to an audit node and a supervision node.

[0032] The audit node is connected to the tax planning module, which is used to calculate and store the user node information. The tax planning module includes a tax planning calculation unit and an encryption storage unit. The encryption storage unit encrypts and packages the calculation data of the tax planning calculation unit and transmits it to the sending module.

[0033] The user node is connected to the audit module. The audit module includes an audit node audit unit and a user node audit unit. The audit node audit unit is connected to the blockchain network. The user node audit unit is interactively connected with the blockchain network for information. The blockchain network also includes a tax planning control output and storage module. Figure 7 It is the operation interface of the audit module in the present invention.

[0034] The preferred solution is Figures 4 to 7 In the embodiment, the user node is a blockchain physical examination terminal, which includes an input module, an output module and a processing module. The input module includes an ID card scanner, a camera, a fingerprint collector and a payment unit. Figures 5 and 6 In the figure, the operation interface of the blockchain physical examination terminal is shown. The blockchain physical examination terminal is the most basic data interaction unit of the present invention. The physical examination of enterprise users and their accompanying tax data enter the tax planning and tax-related blockchain physical examination system through the blockchain physical examination terminal. The blockchain physical examination terminal is mainly composed of four modules, namely: input module, output module and processing module. The input module is composed of a camera, an interactive screen, a chip reader, an ID card scanner, a fingerprint collector and a QR two-dimensional code scanner. The QR two-dimensional code scanner can not only assume the function of a mobile payment unit for scanning payment codes, but also scan other types of two-dimensional codes according to system needs to collect user extended information. This is also the physical basis for the system to have secondary development and performance scalability. The output module is composed of a tax control voucher printer and an A4 paper import and export; the tax control voucher printer is provided with a special maintenance hole, which can be disassembled and repaired by maintenance personnel with professional identities; the A4 paper import and export can perform output tasks such as printing reports, and can also recycle A4 paper materials with user handwritten signatures and scan and upload them. The appearance is composed of a metal case, corporate logo, blockchain medical examination terminal nameplate, instruction manual, heat sink, cabinet buckle, and cabinet lock. The preferred body shell is made of aluminum alloy material, which can effectively protect the internal components and provide good product heat dissipation. At the same time, it can express the manufacturer and usage of the terminal in a concise and beautiful manner. Figure 5 ,6 In the blockchain physical examination terminal, the blockchain physical examination terminal has user-friendly UI interaction features; supports data exchange with mainstream spreadsheets, such as .xlxs, .csv, .sav, and other files; system roles and usage permissions can be set as needed to ensure that people with different system identities use different system functions; the system uses cloud technology to back up data in real time to ensure that precious system data is not damaged or lost; the system supports secondary development, and grassroots units can change the design of specific system functions according to their own business changes; the system restricts the format of data options for secondary development to ensure that no matter how the system functions are updated, the data caliber of the input system does not change significantly, which provides necessary guarantees for the real-time analysis of the system background big data; system logs are generated in a timely manner to facilitate the tracking and maintenance of the system status, and specific system roles can set system transactions to remind downstream nodes in a timely manner. In addition, the system terminal also supports cardless physical examinations. Physical examinees use fingerprints and irises. Iris detection is achieved by loading iris recognition packages and camera firmware, and the qualifications of physical examinees in the database are obtained through biological feature comparison.

[0035] The preferred solution is Figure 3 , 4 In the present invention, a medical health examination device is also provided. In addition to being used for user physical examination operations, the medical health examination device is also used to send the physical examination report to the judgment unit according to the requirements of the blockchain network. The judgment unit is used to judge the consistency between the physical examination report and the user node information. When the consistency test is passed, the judgment unit sends the physical examination report to the blockchain network through the sending module. With this solution, it can be ensured that the physical examination report randomly checked by the blockchain network is consistent with the user node information to be checked. This improves the reliability of information and can significantly reduce the resource consumption of the blockchain network.

[0036] The preferred solution is Figure 1 In the audit module, the DPOS consensus protocol is used to select audit nodes with audit rights. The DPOS consensus protocol refers to delegated proof of stake, which is the fastest, most efficient, most decentralized and most flexible consensus model among all consensus protocols. The right of stakeholders to approve voting is used to solve consensus problems in a fair and democratic manner. Network parameters ranging from fee estimates to block intervals and transaction sizes can be adjusted by selected representatives. The deterministic selection of block producers allows transactions to be confirmed in an average of only 1 second. This consensus protocol is designed to protect all participants from unnecessary logic checks to improve efficiency. Figure 7As shown in the figure, the auditor's work scene interface in the audit module is displayed. Through the information interconnection of blockchain technology, the user node information in the physical examination data of enterprises in different hospitals, such as user name, physical examination amount and physical examination time, can be presented seamlessly on the operation interface of tax auditors. The system can intelligently provide tax auditors with the push of the proposed audit results through intelligent calculation, which can greatly simplify the tediousness of the tax authorities' work, facilitate the collection of tax-related information of physical examinations of enterprises and hospitals, reduce the possibility of errors in tax accounting, and effectively provide real-time data support for corporate tax planning.

[0037] The preferred solution is Figure 1 In the blockchain, regulatory nodes include tax administration departments, industrial and commercial administration departments, banking regulatory departments and other credible third-party institutions, and the blockchain network allocates regulatory keys to each regulatory node.

[0038] In the preferred solution, the user node is also used to query the information of the tax plan and physical examination report through the address of the hospital network end, and perform identity authentication or decryption through the public key and private key;

[0039] The core of the blockchain network is to improve the reliability of information through redundant information storage and mutual authentication, but this solution also leads to a significant decrease in the efficiency of the blockchain network database. To overcome this problem, the user node divides the information related to the physical examination into two parts, one part is the tax planning calculation information, which includes the user identity, physical examination time and physical examination amount; the other part is the physical examination report information, which includes the specific information of the physical examination items and physical examination results. The physical examination report information is based on the random inspection information requirements of the blockchain network and is submitted to the medical health examination equipment through the user node. With this structure, the redundant data of the blockchain network can be greatly reduced, and the links that need mutual authentication can also be reduced, thereby greatly improving the efficiency of the present invention.

[0040] The preferred solution is Figure 3 In the process, the encrypted data packets produced by the tax planning module and the physical examination reports produced by the medical health examination equipment are encrypted by private keys, and then the encrypted data are uploaded to the blockchain network and blocks are produced.

[0041] In the preferred solution, the blockchain network generates new blocks through the network nodes of the hospital, and then adds them to the main chain to form a permanent storage of physical examination data and tax planning data, and adds a timestamp through a hash function; the timestamp is used to ensure that the block follows the timing link in the blockchain network; the blockchain network is a Merkle tree-based structure. The Merkle tree uses the SHA256 algorithm for encrypted input and output, and uses the PoW algorithm to verify the difficulty and workload of creating new blocks. In the defined blockchain network, tax authorities, relevant institutions, medical institutions, and physical examination companies, as different system roles, jointly maintain and ensure the authenticity and validity of information; at the same time, they have different access permissions for different types of information, and there are both publicly visible parts. For example: the number of physical examinations, the name of the unit for physical examinations, etc., and there are also permission-visible parts, for example: with the consent of the patient, a third-party medical research institution can access anonymous patient medical records for medical research.

[0042] The preferred solution is Figure 2 In the blockchain network, there are business chain networks and multiple query sub-chain networks, and the business chain network is connected to multiple query sub-chain networks through an index chain table. With this structure, transferring part of the data to the query sub-chain network can greatly improve the response speed of the entire blockchain network and avoid a large number of query operations affecting the efficiency of the business chain network.

[0043] In the preferred solution, the query subchain network establishes the corresponding blockchain according to the data update load time, and the update load time is the time required for each business to initiate modification and confirm the data;

[0044] The proposed update load of each query subchain network is set to an average value, and the proposed new data is updated to the query subchain network with a load lower than the average value first;

[0045] The maximum value of the update load is also set. When the data chain reaches the maximum value of the update load, no new data will be added.

[0046] When the update load time of all query subchain networks exceeds the maximum value, a new blockchain is established as the query subchain network;

[0047] The chain head of the query subchain network contains the data list of the current blockchain and the data expiration time. When the data expiration time is reached, the corresponding data in the current blockchain is deleted. The chain head also includes the last update load time data.

[0048] The above-mentioned embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The embodiments and features in the embodiments of the present application can be arbitrarily combined with each other without conflict. The protection scope of the present invention shall be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
