Description

Technical Field

[0001] The present invention relates to the technical field of government information processing, and in particular to a government service authorization traceability analysis method, system, equipment and medium. Background Art

[0002] At present, the application scenarios of authorization and delegation in the process of government service are very extensive. Many regions have established online authorization and delegation platforms and solved the authentication of "I can act on behalf of others" through information technologies such as user authentication, face recognition, electronic signatures, and online documents. However, there is still the problem of credible authentication of forged authorization data. At the same time, the authorization and delegation verification process is complicated, applicants and agents have to run errands many times, business processing personnel have a large workload, and the authorization and delegation content, records, documents, and service processes cannot be traced, and there are problems such as legal disputes caused by false authorization.

[0003] Therefore, how to achieve traceability analysis of government service authorization scenarios, improve the feasibility of authorized services, and at the same time improve the user experience of applicants and staff is a technical problem that needs to be solved urgently. Summary of the invention

[0004] The technical task of the present invention is to provide a government service authorization service traceability analysis method, system, equipment and medium to solve the problem of how to realize the traceability analysis of government service authorization service scenarios, improve the feasibility of authorized services, and at the same time improve the user experience of applicants and staff.

[0005] The technical task of the present invention is achieved in the following way: a method for tracing and analyzing the source of government service authorization, which is specifically as follows: Combine blockchain technology with the authorization and entrustment service platform to collect authorization information and service data of government service items in real time through data collection procedures; Use the block chain structure in the blockchain to store, verify and manage the authorization information and business data of collected government service items; Encrypt data transmission and storage through hash encryption algorithm to ensure data security; Use distributed node consensus algorithm to update data in the blockchain to ensure data consistency; Use the Hardhat framework to implement business data transaction smart contract algorithms to prevent data tampering; The data service interface is used to realize the authorization service traceability analysis and information verification of a single business.

[0006] As a preferred option, the data collection program is built based on the springcloud framework. The data collection program collects authorization data and business processing data of various departments; In order to ensure the real-time and integrity of data collection, the data collection program uses the http interface to connect, and the interface type is application / json, post type; The data collection program includes an authorization information entry interface and a business information entry interface; among them, the input parameters of the authorization information entry interface include id (data unique identifier), authorizer name, authorizer ID number, authorizer contact information, authorized person name, authorized person ID number, authorized person contact information, authorization matters, authorization type and authorization time; the output parameters of the authorization information entry interface include a successful save flag and a blockchain flag; the input parameters of the business information entry interface include id (data unique identifier), authorization id (corresponding authorization unique identifier), business name, processing time, processing status, approver, approval opinion, department and processing matter information; the output parameters of the authorization information entry interface include a successful save flag and a blockchain flag; In response to high concurrency situations, the data collection program supports deployment in a distributed mode to achieve real-time data entry for each department without causing congestion. After data collection, it is first parsed and decomposed into block data, then encrypted and waits for the results to be saved.

[0007] As a preferred method, the authorization information and business data of the collected government service items are constructed into a business chain using queue and one-way linked list technology, as follows: The authorization process information and service data of each business are divided into two blocks. In order to ensure high concurrency of access data, a queue is used to put the received block information into the queue in the order of the incoming time according to the first-in-first-out principle, and then the corresponding throughput is set according to the performance of the blockchain for block access; The obtained blocks are stored in the business chain in a one-way list storage format, where each block includes a block header + a block body; the block header includes the block hash, a miniature reference to the previous block address, a timestamp of block generation, the transaction status of this block, the size of this block, and the difficulty of this block.

[0008] As a preferred method, the hash encryption algorithm adopts the SHAA256 algorithm. Through the SHA256 encryption algorithm, the authorization information and application process information involved in the business are encrypted, transmitted and stored in an orderly manner to ensure data security. The SHA256 algorithm is an iterative hash function of the Merkle-Damgard structure. The calculation process of the iterative hash function of the Merkle-Damgard structure is divided into two stages: message preprocessing and main loop. In the message preprocessing stage, the message padding and extended padding are completed, and the input original message is converted into n 512-bit message blocks. Each message block is then processed using the SHA256 compression function. The calculation process is an iterative calculation process. When the last message block (the nth block) is processed, the final output value is the SHA256 value of the input original message.

[0009] As a preferred method, the distributed node consensus algorithm adopts PBFT, which is a Byzantine fault-tolerant consortium chain algorithm. The specific process of PBFT is as follows: ①The client sends a request to invoke the service operation of the primary node; ②The primary node broadcasts the request to the backup node; ③ Each node executes the request and then sends a reply to the client; ④ If the client receives no less than f + 1 (assuming there are 3f nodes in total) identical responses from different nodes, the client will consider the identical responses to be the return results after the operation.

[0010] As a preferred option, the business data transaction smart contract algorithm rules are as follows: Through the smart contract transaction request initiated by the user, the data involved in the transaction request is divided into on-chain data and off-chain data. The on-chain data is processed by consensus through the consensus node of the blockchain, and the off-chain data is calculated and processed through program logic analysis and verification proof is provided; It determines whether the business information in the transaction request message is consistent with the received content, reaches a real-time consensus on the judgment result, and executes the smart contract based on the consensus result.

[0011] Preferably, the authorization service traceability analysis and information verification of a single business is provided through the http interface. The format of providing data traceability and verification services to the outside world is as follows: ① Authorization information tracing service: The input parameter of the authorization information tracing service is the business serial number; the output parameter of the authorization information tracing service is the returned authorization information; the authorization information includes the authorization time, the information of the authorizer, the information of the authorized person and the authorization matters; ②Business information tracing service: The input parameter of the business information tracing service is the business serial number; the output parameter of the business information tracing service is the returned business information; among them, the business information includes application time, authorizer information, authorized person information, matter information, handling link information, handling status, approval time and handling opinions; ③Data verification service: The input parameters of the data verification service are the business serial number, authorizer, authorized person and authorization ID; the output parameters of the data verification service are the returned authorization confirmation information; among them, the authorization confirmation information includes the verification result, authorization time, authorizer information, authorized person information and authorization matters.

DETAILED DESCRIPTION

[0018] The government service authorization service traceability analysis method, system, equipment and medium of the present invention are described in detail below with reference to the drawings and specific embodiments of the specification.

[0019] Embodiment 1: As attached Figure 1 As shown, this embodiment provides a method for tracing and analyzing the source of government service authorization, and the method is specifically as follows: S1. Combine blockchain technology with the authorization and entrustment service platform to collect authorization information and service data of government service items in real time through data collection procedures; S2. Use the block chain structure in the blockchain to store, verify and manage the collected authorization information and business data of government service items; S3, encrypt data transmission and storage through hash encryption algorithm to ensure data security; S4.

Use the Hardhat framework to implement the business data transaction smart contract algorithm to prevent data tampering; S6. Realize the authorization service traceability analysis and information verification of a single business through the data service interface.

[0020] The data collection program in step S1 of this embodiment is built based on the springcloud framework, and the data collection program collects content including authorization data and business processing data of each department; To ensure the real-time and integrity of data collection, the data collection program uses the http interface, and the interface type is application / json, post type; The data collection program includes an authorization information entry interface and a business information entry interface; among them, the input parameters of the authorization information entry interface include id (data unique identifier), authorizer name, authorizer ID number, authorizer contact information, authorized person name, authorized person ID number, authorized person contact information, authorization matters, authorization type and authorization time; the output parameters of the authorization information entry interface include a successful save flag and a blockchain flag; the input parameters of the business information entry interface include id (data unique identifier), authorization id (corresponding authorization unique identifier), business name, processing time, processing status, approver, approval opinion, department and processing matter information; the output parameters of the authorization information entry interface include a successful save flag and a blockchain flag; In response to high concurrency situations, the data collection program supports deployment in a distributed mode to achieve real-time data entry for each department without causing congestion. After data collection, it is first parsed and decomposed into block data, then encrypted and waits for the results to be saved.

[0021] As attached Figure 2 As shown, the authorization information and service data of the government service items collected in step S2 of this embodiment use queue and one-way linked list technology to build a service chain, which is as follows: S201. Divide the authorization process information and service data of each business into two blocks. To ensure high concurrent access to data, a queue is used to put the received block information into the queue in the order of the incoming time according to the first-in-first-out principle. Then, the corresponding throughput is set according to the performance of the blockchain for block access. S202. Store the obtained blocks in the business chain in a one-way list storage manner, where each block includes a block header + a block body; wherein the block header includes a block hash, a miniature reference to the previous block address, a timestamp of block generation, transaction status of this block, size of this block and difficulty of this block.

Each message block is then processed using the SHA256 compression function. The calculation process is an iterative calculation process. When the last message block (the nth block) is processed, the final output value is the SHA256 value of the input original message.

[0023] Blockchain is a distributed decentralized network that provides immutability, privacy, security, and transparency. No central authority exists to validate and verify transactions, but every transaction in the blockchain is considered fully secure and verifiable.

[0025] A smart contract is a computer protocol designed to communicate, verify or execute a contract in an informational manner. Smart contracts allow for trusted transactions without a third party, which are traceable and irreversible. The Hardhat framework is a development environment specifically designed for Ethereum smart contract development. It provides a set of tools and utilities that make it easier to compile, test and deploy smart contracts on the Ethereum network.

[0026] The specific algorithm rules of the business data transaction smart contract in step S5 of this embodiment are as follows: ① Through the smart contract transaction request initiated by the user, the data involved in the transaction request is divided into on-chain data and off-chain data.
