Before explaining the scheme in detail, the technical context of the scheme is briefly introduced:

Blockchain technology is to use the blockchain data structure to verify and store data, use distributed node consensus algorithms to generate and update data, use cryptography to ensure the security of data transmission and access, and use intelligence composed of automated script code. A new distributed infrastructure and computing method that uses contracts to program and manipulate data. Among them, the distributed nodes and consensus algorithm mechanism in the blockchain make the blockchain have the characteristics of decentralization, autonomy, and openness. Cryptography is used to ensure that the information in the blockchain cannot be tampered with. The blockchain is currently divided into public blockchain, alliance blockchain and private blockchain. Among them, each node in the public blockchain is open to anyone, and anyone can download and obtain the complete blockchain data. Public blockchain is the earliest blockchain and the most widely used blockchain.

The inventor found that although the customer has medical insurance awareness, he does not have a high degree of understanding of the insurance contract. After subsequent medical treatment, the insurance product is found to have a certain waiting period; and the insurance product's claim conditions are not clear. I don't know what kind of diagnosis can make claims, which may cause false reports, increase the work of insurance personnel, and may make the customers 'claims untimely, or fail to report, causing customers' property losses.

In order to solve the above problems, the inventors designed the following technical solutions:

This application provides a blockchain-based medical insurance claim method, as shown in FIG. 1, which is a flowchart of a blockchain-based medical insurance claim method according to an embodiment of the present application. Medical insurance claims methods include:

S11. Establish a medical insurance block header for the customer. The medical insurance block header includes the customer's medical insurance contract.

When a customer purchases medical insurance, a medical insurance block header is established for the customer, and the signed medical insurance contract is stored in the medical insurance block header, so that it is convenient to follow up the contract terms and check the claims with the diagnosis certificate. Of course, the medical insurance block header also stores the customer's identity information in order to verify the identity of the customer. The identity information can include name, gender, contact information, home address, family members, insurance type, and so on.

In addition, after the establishment of the medical insurance block header, customers can record each medical information in the block when they seek medical treatment, thereby forming a customer's own medical record chain, which is convenient for customers to understand their physical conditions and achieve the purpose of storing diagnostic certificates.

S12. Establish a medical record chain for the customer, and map the medical record chain to the medical insurance block header. Among them, the medical record chain is a blockchain used to store the customer's medical information. The medical record chain includes at least one block, and one block is the customer Medical information for one visit.

In this embodiment, after the medical record chain is mapped to the medical insurance block header, when the customer logs in to the system to view his own medical records, he can view all the blocks (medical records) up to the current one time, so that it is easy to track and understand his own development It is also convenient for subsequent queries.

Each time the customer visits the doctor's medical information in a block-type recording, a block is generated for each visit to the doctor, which is convenient for customers, medical institutions and insurance companies to make queries.

It should be noted that the medical information involved in this embodiment may include such information as the client's current medical diagnosis, complaining condition, treatment measures, test results, medication, etc. The medical information of this medical treatment is recorded in the medical record chain In a block of this section, the medical institution has absolute authority. Once the record is completed, it cannot be modified or deleted. This guarantees the security of medical information on the one hand and the authenticity of medical information on the other. , Saving the subsequent claims review process.

S13. After the customer seeks medical treatment, the medical information in the block corresponding to the medical treatment is checked against the medical insurance contract in the header of the medical insurance block corresponding to the customer.

In other words, the customer will record the medical information of the current medical treatment in a block each time he visits the doctor. At this time, each time a block is generated, the degree of matching with the medical insurance contract in the head of the medical insurance block needs to be checked. Verify that the diagnosis contained in the medical information matches the terms of the medical insurance contract.

S14. If the verification is successful, the customer will be compensated according to the medical information and medical insurance contract in the block corresponding to the current medical treatment.

The customer will record the medical information of this medical treatment in a block each time he visits the doctor. When the medical treatment is completed, the medical information in the identification block and the terms of the medical insurance contract in the medical insurance block header are automatically verified. Matching degree. When the verification match is high and successful, the customer will be compensated according to the terms in the medical insurance contract. Anyway, if the verification fails, no claim will occur.

What needs to be explained is that claim settlement can be understood as the system automatically notifying the corresponding insurance personnel of the customer. After verifying the situation, the insurance personnel will make claims to the customer according to the medical information in the block corresponding to the medical treatment and the corresponding clauses in the medical insurance contract. . In this embodiment, because the system automatically checks whether the medical information in the block meets the terms in the medical insurance contract in the medical insurance block header according to the generated block, it can save the processing flow such as feedback of the case to the insurance company, and save Labor costs, and the claims cycle is greatly shortened.

In addition, the matching check can be based on keywords. For example, the medical insurance contract is a major disease contract that claims for cancers such as stomach, liver cancer, and esophageal cancer. When related words such as cancer or cancer appear in medical information, then The verification was successful.

In this embodiment, by establishing a medical insurance block header for a customer, and storing the medical insurance contract in the customer's medical insurance block header, and establishing a medical record chain for the customer, the customer medical record chain is mapped to the customer's medical insurance contract. The medical record chain is a blockchain that stores customer medical information. Each time a customer visits a doctor, a block can be generated based on the customer's medical information. The above method completely saves the customer's medical information and ensures the authenticity of the customer's medical information.

Further, in one embodiment, as shown in FIG. 2, it is another flowchart of a blockchain-based medical insurance claim method provided in an embodiment of the present application, and a method for establishing a medical insurance block header for a customer. include:

S110. Obtain the identity information of the customer.

S112. Use the hash algorithm to process the customer's identity information to generate a uniquely identified customer ID.

In this embodiment, the main role of the customer ID is identification and indexing, which facilitates subsequent inquiries.

Still further, in a specific implementation, as shown in FIG. 3, this is another flowchart of a blockchain-based medical insurance claim method provided in an embodiment of the present application, which combines the medical record chain with medical insurance. The method for mapping processing of the block header includes:

S121: Map the absolute address of the block included in the medical record chain and the customer ID of the customer, and record the result of the mapping process in the medical insurance block header corresponding to the customer.

In this embodiment, the customer information stored in the block header of the medical insurance is isolated from the medical information in the block included in the medical record chain, the privacy of the customer is protected, and the leakage of medical data is prevented.

Still further, in another specific implementation manner, referring to FIG. 3 continuously, a method for establishing a medical record chain for a client includes:

S120. When the customer seeks medical treatment, the customer's customer ID is verified, and the medical information generating block for the medical treatment is stored in the blockchain corresponding to the customer.

Inevitably, the medical institution that the customer visits each time may not be unique, so when the customer seeks medical treatment, the medical institution may perform a hash operation based on the identity information, and then compare it with the customer ID to verify the customer ID. After confirming the identity of the customer, the doctor can make an inquiry in the blockchain-based medical insurance system to check the customer's original medical conditions and medication situation, etc., in order to fully understand the customer's physical condition and give a reasonable diagnosis . Because the customer's medical information is recorded in the blockchain every time, when the customer has a crisis situation (unconsciousness), it is convenient for the medical work to make the correct treatment based on the record.

As shown in FIG. 4, this is another flowchart of a blockchain-based medical insurance claim method provided by an embodiment of the present application. A medical institution accesses the blockchain in a network node manner. The way the node performs encryption to verify and guarantee the valid legitimacy of the node. Specifically, before establishing a medical insurance block header for a customer, and the medical insurance block header includes the customer's medical insurance contract, the blockchain-based medical insurance claim method also includes:

S10. The medical institution at the time of the customer's medical treatment is connected to the blockchain-based medical insurance claim system in the form of a network node.

In this embodiment, each medical institution can be registered in the blockchain-based medical insurance claim system, and each successfully registered medical institution can independently form a network node for easy management.

Further, in order to ensure the security of each network node, the network node may be encrypted by an asymmetric encryption method. Public and private keys are generated by asymmetric encryption of all network nodes, where the private key is used to uniquely identify the node, and the public key is used to verify the legitimacy of the node.

The read, write, and modify permissions of each organization are described below, as shown in Table 1:

Table 1 Read, write and modify permissions

As shown in Table 1, only medical institutions have the right to write medical information into the blockchain, and no other person or institution can write. It should be noted that no one or organization has the authority to modify or delete the content in the block, but when the content record in the block is wrong and needs to be corrected, it can be modified by writing again. For example, the first timestamp is written in block A, the second timestamp is written in block B, and the third timestamp is written in block C. At this time, it is learned that there is an error in block A and it needs to be corrected. The fourth timestamp is written in block D, which connects block D with block A. When querying block A, the block D can be associated with the query to complete the block modification.

Since no agency has the right to modify, it can guarantee the authenticity of the data, prevent tampering, and avoid the fraudulent behavior of some customers.

The following briefly describes the claim process:

The customer selects a medical insurance product, completes system registration, establishes a medical insurance block header for the customer, and the medical insurance block header includes the customer's medical insurance contract, and generates a uniquely identified customer ID based on the customer's identity information.

After the medical institution logs in to the system, it verifies the customer ID, and generates a unique customer ID based on the customer identification information. When the unique identification is the customer ID, the identity verification is successful, and the medical information for the medical treatment is written into the area corresponding to the customer in the form of a block. In the block chain, the absolute address of the block and the corresponding customer ID are mapped for subsequent retrieval and reference. The medical information in the block is matched with the medical insurance contract in the header of the medical insurance block corresponding to the customer. If the check is successful, the medical information in the block corresponding to the current medical treatment and the medical insurance contract are checked. Claim. Thereby, rapid settlement of medical insurance can be realized, and customer fraud prevention can be prevented.
