[0002] In the existing insurance industry, claims settlement, as an important part of insurance services, is directly related to the protection of customers' rights and interests and the reputation and operational efficiency of insurance companies. The traditional insurance claims settlement process usually follows the linear model of "claim reporting → claim acceptance → claim review → notification of payment". However, with the continuous expansion of the insurance market and the increasing richness of insurance products, the traditional claims settlement method that relies entirely on manual work has gradually revealed its limitations. Specifically, there are the following main problems:

[0003] Low processing efficiency: The manual review process is cumbersome, involving multiple links such as data collection, verification, and evaluation. Due to human resource constraints, the processing speed is often unable to meet customers' expectations for quick claims settlement, especially during peak periods, when processing time is greatly reduced.

[0004] Low processing accuracy: During the manual review process, human factors (such as fatigue, negligence, misunderstanding, etc.) are difficult to completely avoid, which may lead to errors in the claims results, affecting customer experience and the reputation of the insurance company.

[0005] Therefore, there is an urgent need for a new claims review method that integrates automation and intelligence to achieve comprehensive optimization and upgrading of the claims process. Summary of the invention

[0089] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0090] Continue to refer Figure 2 , showing a flowchart of an embodiment of a blockchain-based claims processing method according to the present application. According to different requirements, the order of the steps in the flowchart can be changed, and some steps can be omitted. The blockchain-based claims processing method provided in the embodiment of the present application can be applied to any scenario where claims processing is required, and the blockchain-based claims processing method can be applied to products in these scenarios, for example, claims processing in the field of finance and insurance. The blockchain-based claims processing method comprises the following steps:

[0091] Step S201, when receiving a claim request from a customer, extracting claim data from the claim request, and calling a preset target identification agency to perform data identification on the claim data; wherein the claim request carries the claim data.

[0092] In this embodiment, the blockchain-based claims processing method is run on an electronic device (e.g. Figure 1 The server / terminal device shown in the figure) can obtain the claim request through a wired connection or a wireless connection. It should be pointed out that the above-mentioned wireless connection method may include but is not limited to 3G / 4G / 5G connection, Wi-Fi connection, Bluetooth connection, WiMAX connection, Zigbee connection, UWB (Ultra Wi-Fi Band) connection, and other wireless connection methods currently known or to be developed in the future. The executor of the present application is specifically a claims processing system, or simply referred to as the system. The present application can be applied to the business scenario of claims processing of insurance companies in the field of financial insurance. The above-mentioned customers may be insured customers of the insurance company. The above-mentioned claim request is a claim application initiated by the customer in the claims processing system. The customer logs in to the claims processing system and uploads the corresponding claim data on the system interface of the claims processing system. The above-mentioned claims data at least includes the insurance contract and claim materials. Exemplarily, the claim materials may include medical records, discharge summaries, original medical expense receipts, medical expense settlement details (prescriptions), copies of medical expense receipts, disease diagnosis certificates, forensic medical appraisal certificates or hospital appraisal certificates (disability appraisal reports), etc.

[0093] The above-mentioned target identification agency can be a trusted third-party identification agency selected by the insurance company or blockchain project team, responsible for digital identification of all insurance contracts and claims materials. The digital identification process includes: carefully reviewing the claims data to confirm its authenticity, integrity and compliance. Then, the target identification agency uses digital signature technology to sign the identification results and generate identification identifiers (such as hash values, timestamps, etc.), and then returns the identification results and identification identifiers to the system in digital form.

[0094] Step S202: If the claim data passes the data authentication, the claim data is structured and parsed to obtain corresponding target claim data.

[0095] In this embodiment, the above-mentioned structured parsing refers to parsing the claim data into a structured data format and extracting the identification identifier to obtain the callable parameters of the smart contract, that is, the above-mentioned target claim data.

[0096] Step S203: construct a transaction based on the target claim data to obtain a corresponding claim transaction, and broadcast the claim transaction to the target blockchain network.

[0097] In this embodiment, the specific implementation process of the above-mentioned transaction construction based on the target claim data to obtain the corresponding claim transaction will be further described in detail in the subsequent specific embodiments of this application, and will not be elaborated in detail here.

[0098] Step S204, determining the verification node corresponding to the claim transaction, and performing node identity verification on the verification node based on the target identification agency; wherein the number of the verification nodes includes multiple.

[0099] In this embodiment, the verification nodes at least include nodes such as insured customers, insurance companies, and regulatory agencies. The specific implementation process of the verification node identity authentication based on the target identification agency will be further described in detail in the subsequent specific embodiments of this application, and will not be elaborated here.

[0100] Step S205: If the verification node passes the node identity authentication, a preset smart contract is executed based on each verification node to verify the claim transaction and obtain a corresponding verification result.

[0101] In this embodiment, the above-mentioned smart contract is a pre-built smart contract corresponding to the claims processing. For the construction process of the smart contract, this application will provide further detailed descriptions in subsequent specific embodiments, and will not be elaborated on here. Among them, when the above-mentioned smart contracts are executed separately based on each of the verification nodes, the smart contract will check whether the target claims data contains a valid identification identifier when receiving the target claims data. Specifically, the smart contract confirms the authenticity of the identification identifier by using a predefined verification algorithm (such as hash value comparison). If the verification passes, the target claims data is considered to be authentic; if the verification fails, the above-mentioned claim request is refused to respond.

[0102] Specifically, the process of verifying the claim transaction includes: checking the legality of the claim transaction. This includes verifying whether the signature of the claim transaction is valid (ensuring that the claim transaction is initiated by the correct account), checking whether the cost of the claim transaction meets the network requirements (such as the Gas fee in Ethereum), and verifying whether the format of the claim transaction complies with the specifications of the target blockchain network. If the claim transaction fails in any verification link, it will be rejected and marked as invalid. If the claim transaction passes the verification, the smart contract executor on the verification node will load and execute the smart contract function specified for the claim transaction. Among them, the smart contract will read the data of the claim transaction (such as the hash value of the claim material, the contract ID, etc.), and execute the corresponding logic to automatically match and verify the claim transaction. For example, it includes comparing with the original contract information, claim rules, and previously stored hash values ​​stored on the blockchain, and then generating the corresponding verification results.

[0103] Step S206: Generate a validity result corresponding to the claim transaction based on the verification result.

[0104] In this embodiment, the specific implementation process of generating the validity result corresponding to the claim transaction based on the verification result will be described in further detail in subsequent specific embodiments of the present application and will not be elaborated on here.

[0105] Step S207: If the validity result is valid, the target claim data is processed based on the smart contract to obtain a corresponding claim result.

[0106] In this embodiment, if the above validity result is valid, that is, the claim transaction is confirmed to be valid, the smart contract will execute the corresponding logic to calculate the claim amount corresponding to the above claim transaction and obtain the corresponding claim result, wherein the claim result may include success / failure status, claim amount, claim time and other data.

[0107] Step S208: Based on the claim settlement result, payment of the claim amount to the customer is processed.

[0108] In this embodiment, the specific implementation process of the above-mentioned payment of the claim amount to the customer based on the claim result will be further described in detail in the subsequent specific embodiments of this application and will not be elaborated in detail here.

[0109] When receiving a claim request from a customer, the present application extracts claim data from the claim request and calls a preset target identification agency to perform data identification on the claim data; wherein, the claim request carries claim data; if the claim data passes the data identification, the claim data is structured and parsed to obtain the corresponding target claim data; then a transaction is constructed based on the target claim data to obtain a corresponding claim transaction, and the claim transaction is broadcast to the target blockchain network; then the verification node corresponding to the claim transaction is determined, and node identity verification is performed on the verification node based on the target identification agency; wherein the number of the verification nodes includes multiple; if the verification node passes the node identity verification, the preset A smart contract is used to verify the claim transaction and obtain a corresponding verification result; subsequently, a validity result corresponding to the claim transaction is generated based on the verification result; if the validity result is valid, the target claim data is processed based on the smart contract to obtain a corresponding claim result; finally, based on the claim result, the claim payment is processed for the customer. In this way, the present application is based on the use of the target blockchain network and the automated program execution based on the smart contract, which can automatically and accurately complete the claim processing for the claim request submitted by the customer, reduce the processing workload of the claims auditor, reduce the error rate of human errors, effectively improve the processing efficiency and accuracy of the claims processing, and is conducive to improving the customer's user experience.

[0110] In some optional implementations, the step of constructing a transaction based on the target claim settlement data to obtain a corresponding claim settlement transaction in step S203 includes the following steps:

[0111] Construct a blockchain transaction.

[0112] In this embodiment, a blockchain transaction that can be broadcast to the blockchain network can be first constructed.

[0113] The target claim data is set as the data part of the blockchain transaction to obtain a corresponding first blockchain transaction.

[0114] In this embodiment, after the above-mentioned blockchain transaction is constructed, the target claim data obtained through structured analysis can be used as the data part of the above-mentioned blockchain transaction to obtain the corresponding first blockchain transaction.

[0115] The function and parameters of calling the smart contract are specified in the first blockchain transaction to obtain the corresponding second blockchain transaction.

[0116] In this embodiment, the function and parameters of the smart contract are pre-built designated data corresponding to the insurance claim processing. For example, the function of the smart contract may include submitC laim. The parameters may include the insurance contract ID, the hash value of the claim materials, etc.

[0117] The second blockchain transaction is used as the claim settlement transaction.

[0118] In this embodiment, the caller's account information can be further specified in the blockchain transaction to obtain the final claim transaction, thereby improving the completeness and accuracy of the obtained claim transaction.

[0119] This application constructs a blockchain transaction; then sets the target claim data as the data part of the blockchain transaction to obtain the corresponding first blockchain transaction; then specifies the function and parameters of calling the smart contract in the first blockchain transaction to obtain the corresponding second blockchain transaction; and subsequently uses the second blockchain transaction as the claim transaction. This application sets the target claim data as the data part of the constructed blockchain transaction, and specifies the function and parameters of calling the smart contract in the blockchain transaction, so that the transaction construction processing of the target claim data can be completed quickly and accurately, ensuring the accuracy and standardization of the obtained claim transaction.

[0120] In some optional implementations of this embodiment, the performing node identity authentication on the verification node based on the target authentication agency in step S204 includes the following steps:

[0121] Obtain a digital certificate provided by the verification node.

[0122] In this embodiment, an identity authentication mechanism for nodes in the target blockchain network is pre-established. The blockchain project team selects the required identity authentication technology based on project requirements and security requirements, and develops a set of clear identity authentication standards and processes, including how to generate digital certificates, how to manage public and private keys, and how to perform identity authentication.

[0123] Specifically, each node in the target blockchain network (including insured customers, insurance companies, regulators, etc.) needs to register its identity information in the target blockchain network. This usually involves submitting some necessary identity verification materials, such as business licenses, ID cards, etc. In turn, the certification body in the target blockchain network (which can be an independent third-party certification body or part of the target blockchain network) reviews the identity information of the node, and if the verification is passed, it will issue a digital certificate for it. The digital certificate usually contains the node's public key, the signature of the certificate issuer, the validity period, and other information. The node stores its own digital certificate in the target blockchain network and displays it when needed.

[0124] A public key of a preset certificate issuer is obtained based on the target authentication authority.

[0125] In this embodiment, the certificate issuer specifically refers to the certification authority in the target blockchain network.

[0126] The digital certificate is verified based on the public key of the certificate issuer.

[0127] In this embodiment, the target authentication agency verifies the digital certificate provided by the verification node by using the acquired public key of the certificate issuer to confirm the authenticity and validity of the digital certificate.

[0128] If the digital certificate passes the verification, it is determined that the verification node passes the node identity authentication; otherwise, it is determined that the verification node fails the node identity authentication.

[0129] In this embodiment, if the authenticity and validity of the digital certificate are confirmed, it is determined that the digital certificate has passed the verification, and then it is determined that the verification node has passed the node identity authentication. If the authenticity and validity of the digital certificate are not confirmed, it is determined that the digital certificate has not passed the verification, and then it is determined that the verification node has not passed the node identity authentication. In addition, after the digital certificate is verified, the target blockchain network will control the operation authority of the verification node according to the information in the digital certificate (such as role, authority, etc.). The verification node that has not passed the identity authentication will not be able to participate in voting or perform sensitive operations.

[0130] This application obtains the digital certificate provided by the verification node; then obtains the public key of the preset certificate issuer based on the target identification agency; subsequently verifies the digital certificate based on the public key of the certificate issuer; if the digital certificate passes the verification, it is determined that the verification node passes the node identity authentication, otherwise it is determined that the verification node fails the node identity authentication. This application obtains the digital certificate provided by the verification node, and then obtains the public key of the preset certificate issuer based on the use of the target identification agency, and verifies the digital certificate according to the public key of the certificate issuer. If the digital certificate passes the verification, it is determined that the verification node passes the node identity authentication, otherwise it is determined that the verification node fails the node identity authentication, thereby achieving rapid and accurate completion of the node identity authentication processing for the verification node corresponding to the claim transaction, and ensuring the accuracy of the node identity authentication result. And only when it is determined that the verification node passes the node identity authentication, the verification node will be used to continue to execute the response processing for the claim request, which improves the processing standardization and processing security of the claim request, and effectively ensures the validity and accuracy of the claim transaction corresponding to the claim request in the entire target blockchain network.

[0131] In some optional implementations, step S206 includes the following steps:

[0132] A voting result corresponding to the claim transaction is generated based on the verification result.

[0133] In this embodiment, the verification result includes verification passed or verification failed. If the verification result of the node is verification passed, a voting result corresponding to the verification result is generated, which is a content that agrees with the transaction. If the verification result of the node is verification failed, a voting result corresponding to the verification result is generated, which is a content that disagrees with the transaction.

[0134] Filter out designated voting results that agree to the transaction from the voting results.

[0135] In this embodiment, the voting results generated corresponding to each verification node may be content-screened to obtain a designated voting result whose content is approval of the transaction.

[0136] Determine whether the number of the specified voting results is greater than a preset number threshold.

[0137] In this embodiment, the number of the designated voting results can be obtained by counting the number of the designated voting results. The value of the quantity threshold is the product of all voting results and the designated ratio. There is no specific limitation on the selection of the value of the designated ratio, which can be set according to actual processing requirements, for example, 2 / 3.

[0138] If so, a first validity result is generated indicating that the content corresponding to the claim transaction is valid.

[0139] In this embodiment, if it is detected that the number of the specified voting results is greater than the above-mentioned quantity threshold, it is determined that the claim transaction has reached the consensus of the majority of verification nodes, so that the claim transaction will be considered valid and accurate, and then a first validity result is generated that the content corresponding to the claim transaction is valid.

[0140] If not, a second validity result is generated indicating that the content corresponding to the claim transaction is invalid.

[0141] In this embodiment, if it is detected that the number of the specified voting results is less than the above-mentioned quantity threshold, it is determined that the claim transaction has not reached the consensus of the majority of verification nodes, so that the claim transaction will not be considered valid and accurate, and a second validity result is generated that the content corresponding to the claim transaction is invalid.

[0142] This application generates a voting result corresponding to the claim transaction based on the verification result; then selects the designated voting result with the content of agreeing to the transaction from the voting result; and subsequently determines whether the number of the designated voting results is greater than a preset number threshold; if so, generates a first validity result with the content corresponding to the claim transaction being valid; if not, generates a second validity result with the content corresponding to the claim transaction being invalid. After verifying the claim transaction and obtaining the corresponding verification result, this application generates a voting result corresponding to the claim transaction based on the verification result, and selects the designated voting result with the content of agreeing to the transaction from the voting result, and then analyzes the number of the designated voting results. If it is detected that the number of the designated voting results is greater than the preset number threshold, the first validity result with the content corresponding to the claim transaction being valid is automatically and accurately generated, otherwise the second validity result with the content corresponding to the claim transaction being invalid is generated, thereby achieving rapid and accurate generation of the validity result corresponding to the claim transaction based on the verification result, and effectively ensuring the data accuracy of the validity result of the generated target claim data. And only when the validity result is determined to be valid, will the target claim data be subsequently processed based on the smart contract to obtain the corresponding claim result, and the claim payment to the customer will be processed based on the claim result, effectively improving the processing standardization and processing security of the claim processing corresponding to the claim request.

[0143] In some optional implementations, step S208 includes the following steps:

[0144] A claim amount numerical value is determined from the claim settlement result.

[0145] In this embodiment, the above-mentioned claim settlement result at least includes data such as success / failure status, claim settlement amount, claim settlement time, etc. The claim settlement amount value corresponding to the claim settlement amount included in the claim settlement result can be obtained by performing data analysis on the claim settlement result.

[0146] A blockchain wallet address corresponding to the client is determined.

[0147] In this embodiment, the customer information (such as the customer name) of the customer can be obtained, and then the blockchain wallet address corresponding to the customer can be queried according to the customer name.

[0148] The target claim amount corresponding to the claim amount value is deducted from the preset smart contract account.

[0149] In this embodiment, the above-mentioned smart contract account may specifically be a smart contract account of an insurance company or a related institution.

[0150] The target claim amount is transferred to the blockchain wallet address.

[0151] In this embodiment, the target claim amount can be transferred to the blockchain wallet address in the form of digital currency to complete the claim payment process for the customer. The transfer process corresponding to the target claim amount is also recorded in the form of a transaction on the target blockchain network to ensure the transparency and traceability of the transfer. In addition, the customer can view and confirm the claim amount received through his own blockchain wallet.

[0152] This application determines the value of the claim amount from the claim result; then determines the blockchain wallet address corresponding to the customer; then deducts the target claim amount corresponding to the value of the claim amount from the preset smart contract account; and subsequently transfers the target claim amount to the blockchain wallet address. This application determines the value of the claim amount from the claim result, then deducts the target claim amount corresponding to the value of the claim amount from the preset smart contract account, and transfers the target claim amount to the blockchain wallet address corresponding to the customer, thereby automatically and accurately completing the claim processing for the claim request submitted by the customer, effectively improving the processing efficiency and accuracy of the claim processing, and is conducive to improving the customer's user experience.

[0153] In some optional implementations of this embodiment, before step S205, the electronic device may further perform the following steps:

[0154] Get the input smart contract code corresponding to the claims processing.

[0155] In this embodiment, the above-mentioned smart contract code may be a contract code written by the developers of the insurance company using a smart contract programming language according to actual business needs. Specifically, the developers cooperate with the legal, product and other departments of the insurance company to clarify the detailed rules such as the contract terms, claim conditions and claim amounts of each type of insurance. Then, based on the results of the demand analysis, the smart contract code is written using smart contract programming languages ​​such as Solidity. The smart contract code contains anti-counterfeiting verification logic, such as using a hash algorithm to summarize the insurance contract and claim materials, and compare them with the original hash value stored on the blockchain. Specifically, the content of the smart contract code may include: anti-counterfeiting verification of insurance contracts and claim materials -> conversion to judgment program input parameters -> automatic claim matching of contracts and parameters -> obtaining claim results.

[0156] The smart contract code is tested based on a preset testing strategy.

[0157] In this embodiment, the above-mentioned testing strategy includes unit testing and integration testing. The processing process of unit testing includes: testing each functional module of the smart contract by writing test cases to ensure its functional correctness. The processing process of integration testing includes: deploying the smart contract into the test environment, performing integration testing with other systems or contracts, and verifying whether its interaction with other components meets expectations.

[0158] If the smart contract code passes the code test, the smart contract code is compiled based on the compilation tool in the target blockchain network to obtain the corresponding smart contract.

[0159] In this embodiment, a tool with a code compilation function is used as the compilation tool. If it is detected that the smart contract code passes the code test, the smart contract code is compiled by using the compilation tool to generate a deployable bytecode, that is, the smart contract.

[0160] Use the deployment tool in the target blockchain network to generate a deployment script corresponding to the smart contract.

[0161] In this embodiment, by using a tool with a script deployment function as the above-mentioned deployment tool, a deployment script corresponding to the smart contract is created based on the deployment tool, and parameters such as the bytecode, deployment account, and transaction fee (such as Gas fee) of the smart contract are specified in the deployment script.

[0162] Based on the deployment script, the smart contract is deployed in the target blockchain network.

[0163] In this embodiment, the deployment script is sent to the target blockchain network by using the API or command line tool of the general blockchain platform, and after waiting for the nodes in the target blockchain network to verify the transaction and reach a consensus, the smart contract will be successfully deployed on the target blockchain network.

[0164] This application obtains the input smart contract code corresponding to the claims processing; then performs code testing on the smart contract code based on a preset test strategy; if the smart contract code passes the code test, the smart contract code is compiled based on the compilation tool in the target blockchain network to obtain the corresponding smart contract; then the deployment script corresponding to the smart contract is generated using the deployment tool in the target blockchain network; subsequently, the smart contract is deployed in the target blockchain network based on the deployment script. After obtaining the input smart contract code corresponding to the claims processing, if it is detected that the smart contract code passes the code test, the smart contract code is compiled based on the compilation tool in the target blockchain network to obtain the smart contract, and then the deployment script corresponding to the smart contract is generated using the deployment tool in the target blockchain network, and then the smart contract is deployed in the target blockchain network based on the deployment script, thereby achieving fast and intelligent completion of the deployment of the smart contract, effectively ensuring the accuracy of the deployment of the smart contract.

[0165] In some optional implementations of this embodiment, after step S208, the electronic device may further perform the following steps:

[0166] Obtain target parameters corresponding to the claim settlement result.

[0167] In this embodiment, the above-mentioned claim settlement result may at least include data such as success / failure status, claim settlement amount, claim settlement time, etc. The above-mentioned target parameter refers to the relevant parameter corresponding to the corresponding claim settlement result generated after the claim settlement process.

[0168] Determine the target storage format.

[0169] In this embodiment, the target storage form is specifically a transaction form.

[0170] Based on the target storage format, the claim settlement result and the target parameters are stored on the target blockchain network.

[0171] In this embodiment, the claim settlement result and the target parameter can be recorded in the form of a transaction on the target blockchain network. These records are public, transparent and cannot be tampered with, and any participant of the target blockchain network can obtain this information by querying the blockchain.

[0172] This application obtains the target parameters corresponding to the claim result; then determines the target storage format; and subsequently stores the claim result and the target parameters on the target blockchain network based on the target storage format. After processing the payment of the claim amount for the customer based on the claim result, this application will also intelligently obtain the target parameters corresponding to the claim result, and then store the claim result and the target parameters on the target blockchain network based on the determined target storage format, thereby effectively ensuring the data security and non-tamperability of the claim result and the target parameters, and improving the intelligence of data storage.

[0173] In some optional implementations, the user information obtained has been consented to by the user and complies with the relevant laws and policies. In addition, this application reduces the probability of insurance fraud and reduces the losses of insurance companies through the tamper-proof capability of the blockchain, digital encryption technology, the authority of the appraisal agency, transparent supervision and other public participation.

[0174] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.

[0175] It should be emphasized that in order to further ensure the privacy and security of the above-mentioned claims results, the above-mentioned claims results can also be stored in a blockchain node.

Each data block contains a batch of network transaction information, which is used to verify the validity of its information (anti-counterfeiting) and generate the next block.
