[0042] At present, the opening and management process of traditional social security cards is cumbersome, with information security risks and low data timeliness, and the business data of each link is not transparent. This application proposes a method for online opening and management of third-generation social security cards based on blockchain technology. By building a blockchain, it is agreed that each business participant will be on the chain, where each business participant includes but is not limited to social security management agencies, banks, card merchants, logistics service providers, etc., and smart contracts such as verifying user information and social security card operations are published on the chain to realize the online processing of the entire chain of business processes of the third-generation social security card from user application to card collection and social security agency management. While improving the efficiency of opening and management of the third-generation social security card, it also ensures the security, timeliness and traceability of business data.

[0043] like Figure 1 As shown, the embodiment of the present invention discloses a social security card opening management method based on blockchain, and the steps of the process include:

[0044] Step S100: construct a unified blockchain platform, which includes a social security card management agency node, a bank node, a card merchant node, and a logistics service provider node.

[0045] Step S200: Obtain the user identity information and identity verification materials submitted by the user. The social security card management agency node receives the user identity information submitted by the user, performs a preliminary review based on the identity verification materials, and stores the user identity information that has passed the review on the chain.

[0046] Step S300: Verify the user identity information through a smart contract. After the user identity information is verified, a unique social security card number is generated at the social security card management agency node, and the social security card account information and the corresponding user identity information are stored on the chain. The card opening application is triggered through a smart contract, and the card opening application instruction is broadcast to the bank node and the card merchant node.

[0047] Step S400, the bank node receives the card opening application instruction from the social security card management agency node, obtains the social security card account information and corresponding user identity information from the chain, performs social security card financial card opening, generates a unique social security card financial card number, stores the social security card financial card number, financial information, etc. on the chain, triggers the card making application through the smart contract, and broadcasts the card making application instruction to the card merchant node.

[0048] Step S500, the card merchant node receives the card opening application instruction and the card making application instruction, verifies through the smart contract whether the card opening application instruction and the card making application instruction are consistent on the social security card management agency node and the bank node, and after the verification, performs social security card physical card making, generates a social security card physical card, stores key information such as card making information on the chain, generates logistics transportation instructions through the smart contract, and broadcasts the logistics transportation instructions to the logistics service provider node.

[0049] Step S600: The logistics service provider node receives the logistics transportation instruction, obtains the physical social security card and related information to be transported on the chain, generates a logistics order, and stores key data such as logistics order information and logistics transportation information on the chain.

[0050] Step S700: Obtain on-chain data from the social security card management agency node for query.

[0051] Step S800: Configure the corresponding smart contract to automatically execute tasks according to preset rules and logic.

[0052] In an embodiment of the present invention, building a unified blockchain platform specifically includes steps S101, S102, S103, and S104.

[0053] Step S101. Build a blockchain-based alliance chain and put business participants on the chain. The alliance chain includes multiple nodes, and the nodes are used to represent business participants. The business participants include social security management agencies, banks, card merchants, and logistics service providers.

[0054] In an embodiment of the present invention, it is necessary to build a blockchain-based alliance chain platform and invite various business participants to go online, wherein the alliance chain platform includes multiple nodes, each node represents a business participant, and each business participant includes but is not limited to social security management agencies, banks, card merchants, logistics service providers, etc., that is, the alliance chain platform includes at least social security management agency nodes, bank nodes, card merchant nodes, and logistics service provider nodes, and all business participants can interact and share data on a unified platform.

[0055] Step S102: Formulate unified data standards and interface specifications.

[0056] Among them, data standards and interface specifications include data format, encryption method, transmission protocol, etc., to ensure smooth data exchange and verification between nodes of various business participants, and to achieve data consistency and verifiability between nodes.

[0057] Step S103: Store a copy of the ledger on each node based on the distributed ledger technology, and synchronize the ledgers of all nodes based on the consensus mechanism.

[0058] Each business participant node has a complete copy of the ledger. When the data changes during the social security card opening process, these changes will be synchronized to all nodes, ensuring the consistency and timeliness of the data.

[0059] Step S104. Write a corresponding smart contract according to the business rules for opening a social security card, publish the smart contract on the blockchain, and automatically execute tasks according to preset rules and logic.

[0060] According to the business rules for opening social security cards, corresponding smart contracts are written and published on the blockchain, including identity authentication, authorization management, data integration, card application processing, automatic card production, etc. It can automatically perform tasks according to preset rules and logic, reducing manual intervention and error rates.

[0061] The present invention also provides a possible implementation scheme, which can build a unified blockchain platform, including: utilizing the permission control mechanism of the blockchain to achieve fine management of the data access rights of each node, that is, only authorized nodes or users can access specific data resources, such as banks and social security management agencies can access application user information, while card merchants have no right to access the user information, thereby ensuring the safe sharing and use of data; using a multi-party consensus mechanism to integrate information between various business participants, and using a consensus mechanism in the process of opening a social security card to ensure the consistency and credibility of the data. In the process of data integration, all business participants conduct consensus confirmation on the integrated data to ensure the authenticity and integrity of the data.

[0062] The embodiment of the present invention uses blockchain technology through distributed ledger and encryption mechanism to ensure that all data in the process of opening a social security card cannot be tampered with, effectively avoiding the risk of malicious modification or deletion of data, and ensuring the authenticity and integrity of social security card information. In addition, by putting all business participants involved in the process of opening a social security card on the chain, information silos are broken, and cross-departmental information sharing and intercommunication can be achieved. There is no need to transmit and confirm data through multiple intermediate links, which improves the timeliness and accuracy of data and simplifies the process of opening a social security card. Users only need to submit application information on the user side, and relevant departments can obtain and process it in real time through the blockchain, which greatly improves the user experience.

[0063] The embodiment of the present invention also provides the main process based on each node of the blockchain during the online opening and management of the third-generation social security card, including:

[0064] The user submits personal information (such as name, ID number, contact information, etc.) and identity verification materials (such as ID card scan, face recognition, etc.) on the user end, and the user end sends the information to the social security card management agency for preliminary review. After the review is passed, the relevant information is sent to the blockchain network for further verification through smart contracts to ensure the authenticity and uniqueness of the information. Zero-knowledge proof, homomorphic encryption and other technologies are used to protect user privacy data to ensure verification and operation without leaking the original data;

[0065] After the social security card management agency node verifies the user's application, a social security card account is opened for the user and a unique social security card number is generated. Key data such as social security card account information, user identity information and opening time are stored on the chain, and the card opening application processing is triggered by the smart contract. The card opening instruction is automatically broadcast to the bank and card manufacturer nodes. The social security card management agency node can also be used to implement online management including user information modification, card opening progress query, social security card loss report, social security card cancellation, social security card reissue, financial information query, basic information management, etc. The corresponding operation records will be uploaded to the blockchain for storage;

[0066] The bank node receives the card opening instruction from the social security management agency in real time, obtains the identity information and account information of the corresponding card opening user on the chain, and the bank background automatically performs social security card financial card opening and generates a unique social security card financial card number. After the generation is completed, the social security user's financial card number, financial account information and other key data are stored on the chain, and the card application processing is triggered through the smart contract. The card making instruction is automatically broadcast to the card making merchant node. Bank nodes can also be used to implement other services including reporting the loss of social security financial cards, unblocking social security financial cards, canceling social security financial cards, activating social security financial cards, replacing social security financial cards, social security financial card balance (inquiry), social security financial card details (inquiry), and social security financial card account movement. The bank stores financial information on the chain and uses the instructions of the smart contract to call other services of the bank to implement tasks;

[0067] The card merchant node receives the social security card management agency's card application instructions and the bank's card application instructions in real time, checks and verifies the consistency of the instructions and data on the blockchain from the social security card management agency and the bank through smart contracts, and after verification, it produces the social security physical card, generates the third-generation social security card physical card, stores the key data such as the card production information on the chain, and automatically generates logistics transportation instructions through smart contracts and broadcasts them to the logistics service provider node;

[0068] The logistics service provider node receives the card merchant's logistics and transportation instructions in real time, obtains the cards to be transported and related information on the chain, automatically generates logistics orders, and stores key data such as logistics order information and logistics transportation information on the chain, so that all business participants can grasp the logistics situation in real time. Finally, the logistics service provider will send the physical social security card to the user.

[0069] In the embodiment of the present invention, after each business participant is on the chain, based on the multi-party consensus mechanism of data, the information barriers between different departments in the traditional model are broken, and the real-time sharing and integration of cross-departmental data are realized. Based on the tamper-proof and security of data in blockchain technology, when the social security card management agency faces the functions of querying the progress of social security card opening, the progress of physical card logistics, the financial status of social security card, etc., which rely on the data of non-agency data, it can be directly realized by obtaining the data on the chain; when facing the transaction functions of social security card loss, social security card unblocking, social security card cancellation, etc., which need to link with business participants such as banks, the corresponding smart contract can be issued to automatically execute tasks according to the preset rules and logic to realize the transaction function, improve the handling efficiency and reduce manual intervention and error rate. At the same time, all key operations and time of online management of social security cards are recorded on the blockchain, so that the whole process can be traced, which is convenient for audit and supervision, and realizes the online management of social security cards.

[0070] The embodiments of the present invention realize the on-chain sharing of user information, card opening data, logistics information, social security and financial information, etc., implement access control and identity authentication mechanisms, and prevent unauthorized access and operations.
