Description

Method and device for sharing medical expense information based on blockchain {METHOD AND APPARATUS FOR SHARING INFORMATION ON HOSPITAL COST BASED ON BLOCKCHAINS}

It relates to a method and apparatus for sharing medical expense information based on a block chain. Specifically, the present invention identifies medical expenses for each treatment item from a treatment fee receipt for treatment performed in an animal hospital, matches pre-categorized disease codes for treatment items, and includes information on medical expenses for each disease code. It relates to a method and apparatus for sharing information through a blockchain.

In veterinary hospitals, the principle of the same treatment fee applied to general medical care is not applied due to the absence of an appropriate medical evaluation agency and the absence of a standard medical treatment code. As a result, electronic medical records (EMR) are not applied to veterinary hospitals, and the quality of service and medical expenses differ greatly depending on the area and size of veterinary hospitals.

Since it is virtually impossible for consumers to obtain reliable evaluation information for veterinary hospitals, information asymmetry occurs between medical service providers and consumers for animals. Accordingly, excessive medical treatment occurs, causing a problem of generating excessive costs and a medical accident.

Although the domestic insurance industry introduced companion animal medical insurance, domestic non-life insurance companies that launched companion animal medical insurance products have a loss ratio of over 100%. The reason for this is the lack of standard treatment codes in the medical system of veterinary hospitals and the use of blind spots such as the absence of electronic medical records.

Accordingly, there is a need for a method and apparatus capable of standardizing treatment items as treatment codes, and collecting objective data on how much treatment costs were charged according to standardized treatment codes for each veterinary hospital.

In addition, each application unit 11 of the plurality of nodes 10 generates a new block connected to the block chain when a block containing the first hash value corresponding to the transaction related to treatment information is generated according to a preset block chain related algorithm. It is possible to compete with other nodes 10 to obtain authority.

According to an embodiment, among the mode nodes 10 constituting the block chain, the application unit 11 of the node 10 in which the proof of work for the block corresponding to the treatment information or authentication information is made is a new block corresponding to the authentication information. It occupies the creation authority of, and after generating a new block corresponding to medical treatment information or authentication information, it can be transmitted to one or more other node(s) 10 participating in the blockchain.

At this time, Proof of Work (PoW) may be preset in the application unit 11 as an algorithm of a method of proving that the user has participated in the corresponding work by repeating the process of finding a block hash below the target value numerous times.

In addition, the application unit 11 combines the creation date and time of the new block, the version, the bits, the root hash, the hash of the previous block, and a temporary value called a nonce, and converts it into a hash. Block hash value of

Accordingly, the application unit 11 of each node 10 constituting the block chain combines all transactions made during the generation cycle of the block corresponding to the new block to form a new block. A plurality of different nodes 10 may compete with each other to find a hash value less than a target value in order to occupy the right to generate a new block for connection to the previous block of the new block.

In addition, among the numerous nodes 10 participating in the network, the node 10 that first finds the block hash value below the target value wins the competition, and the winning node 10, the node 10 that first finds the block hash. The application unit 11 of (B) notifies the mode node 10 that it has won the competition and sends a new block generated by the application unit 11 of the winning node 10 (B) to the winning node 10 ( It can be transmitted to one or more nodes 10 other than B).

In addition, the application unit 11 of the other node(s) 10) (C) participating in the blockchain-related network other than the winning node 10 (B) is the new block received from the winning node 10 (B). If there is no abnormality after checking the validity, the approval information that approved the creation of the new block may be transmitted to other node(s) 10 constituting the blockchain other than the self.

In addition, the application unit 11 of each of the plurality of nodes 10 participating in the network collects approval information received from the node(s) 10 other than the node 10 to which it belongs, and the nodes participating in the entire network ( If a majority of 10) approve a newly created block, the new block can be adopted as a formal block and added to a preset shared ledger.

In this case, the application unit 11 may connect and store the new block like a chain to the previous block generated immediately before the creation of the new block among one or more blocks included in the shared ledger.

In addition, the application unit 11 of the winning node 10 (B) generates reward information corresponding to a preset amount when obtaining permission to generate a new block and stores it in the electronic wallet set in advance in the winning node 10 (B). I can.

Meanwhile, in addition to the above-described configuration, the application unit 11 of each of the nodes 10 constituting the block chain calculates the share ratio of nodes having a certain share or more based on the accumulated and stored reward information generated through the block chain. , In a manner in which the probability of being selected as a block generator is determined in proportion to the stake held by each node, that is, a node randomly selected according to the proof of stake may be set as the winning node 10 (B).

In addition, the application unit 11 of the winning node 10 (B) may generate a new block corresponding to medical treatment information or authentication information and transmit it to other nodes 10 (A, C).

According to the above-described configuration, the application unit of each of a plurality of different nodes can store a new block in a preset shared ledger by linking it with the previous block.Through this, even if a specific node is forged and medical information is forged, the shared ledger based on the blockchain If the hash value of a block stored in a specific node connected like a chain using a hash changes due to forgery, it is possible to easily find the block whose hash value has changed when it is checked against the shared ledger of another node to detect forgery of medical information. Therefore, the integrity and stability of medical information-related data can be guaranteed.
