Description

Technical Field

[0001] The present invention relates to the field of electronic digital data processing, and in particular to a supply chain bill system based on blockchain technology. Background Art

[0002] With the development of the global economy and the complexity of supply chain management, supply chain bills play an increasingly important role in inter-enterprise trade. Supply chain bills are usually used to record and track the entire flow of goods from suppliers to end customers. Traditional bill management systems mainly rely on paper documents and centralized electronic systems, which have many problems and challenges. First, paper bill management is inefficient, easy to lose and damage, and difficult to achieve real-time updates and multi-party sharing. The parties spend a long time in the process of bill delivery and confirmation, which increases transaction costs and operational risks. At the same time, the forgery and tampering of paper bills are difficult to prevent, which seriously affects the security and trust of transactions. Secondly, although the centralized electronic bill system has improved management efficiency to a certain extent, there is still a risk of data tampering, loss and leakage due to the centralized storage of data on a single server or a few servers. In addition, the incompatibility of systems between different enterprises and the lack of uniformity of standards have led to serious information islands, and it is impossible to achieve efficient collaboration and interoperability across enterprises and systems.

[0003] The foregoing discussion of the background art is intended only to facilitate an understanding of the present invention. This discussion does not acknowledge or admit that any of the material referred to is part of the common general knowledge.

[0004] Many bill processing systems have been developed. After a lot of searching and reference, it is found that the existing bill processing systems are such as the system disclosed in the publication number CN112149077B. These system methods generally include: receiving the issuance request of the supply chain bill, and obtaining the bill data and the bill issuer according to the issuance request, adding the bill issuer to the authority identifier corresponding to the bill data, and storing the bill data on the blockchain through consensus. However, this system simply applies blockchain technology to the bill system processor, which only solves the authenticity problem but not the risk problem. Fraud is still prone to occur in the bill processing process, and security needs to be improved. Summary of the invention

[0005] The purpose of the present invention is to propose a supply chain bill system based on blockchain technology to address the existing deficiencies.

[0006] The present invention adopts the following technical solution:

[0010] The background management module includes an application classification unit, an instruction generation unit and an application feedback unit. The application classification unit is used to receive application information sent by the foreground application module and classify the application information. The instruction generation unit extracts key information from the application information based on the classification result to generate an instruction and sends it to the service processing module or the block recording module. The application feedback unit is used to receive the instruction feedback results of the service processing module and the block recording module and perform subsequent processing;

[0011] The service processing module includes an instruction activation unit, a service execution unit and an information feedback unit. The instruction activation unit is used to receive instruction information and activate the corresponding execution processor. The service execution unit is used to execute the corresponding ticket service content. The information feedback unit is used to feed back the ticket service information to the background management module.

[0012] Furthermore, the interface display unit includes a framework display processor and a basic information processor, the framework display processor is used to display the framework information of the interface, and the basic information processor obtains specific display content in the display interface;

[0013] The basic information processor directly obtains user information after the user successfully logs in, automatically generates basic query application information and sends it to the background management module, waits to receive user basic information fed back by the background management module and displays the user basic information at a corresponding position in the frame;

[0014] Furthermore, the service execution unit includes an execution processor and a verification processor, wherein the execution processor is used to execute instruction information, and the verification processor is used to verify the ticket-related information during the execution of the instruction;

[0015] The execution processor is divided into the billing execution processor, the endorsement execution processor, the discount execution processor and the settlement execution processor according to the service type of the bill;

[0016] Furthermore, the basic information processor queries and counts the user's ticket status information, and calculates the user's credit index P according to the following formula:

[0017]

[0018] Where n1 is the number of bills in the initial state of the user as a bill issuer, n2 is the number of bills in the transfer state of the user as a bill issuer, n3 is the number of bills in the completed state of the user as a bill issuer, n4 is the number of bills in the expired state of the user as a bill issuer, and k is the credit penalty coefficient;

[0019] The credit index is displayed in the interface display unit as the basic information of the user;

[0020] Furthermore, when executing the endorsement and discounting services, the execution processor calculates the security index Q of the bill according to the following formula:

[0021]

[0022] Where P1 is the credit index of the bill issuer, m is the number of endorsements in the bill cycle, P2(i) represents the credit index of the i-th endorser, and P2 is the credit index of the current endorser;

[0023] In particular, when the current service is a discounted service, P2 is 0;

[0024] The execution processor sends the security index to the recipient of the ticket.

[0025] The beneficial effects achieved by the present invention are:

[0026] This system ensures the authenticity of bills through blockchain technology, obtains the credit information of each user through analysis of historical bill information, and during the bill transfer process, analyzes the bill's existing processing stages and the credit information of the users involved to obtain the security of the bill, so that the bill transferee can better judge whether to accept the transfer of the bill, thereby reducing the risk in the bill transfer process.
